Owned the Platinum Mk 4 in piano black when they first came out..
Have a set of Upgraded.Originals now...running a Sunfire 300x2 amp...
a marriage made in "Heaven." Going to get another amp soon and biamp them

I bought a pair of Plat III's in 1990, and I've regularly went out to find something that could dislodge me from these being my reference. They're still here. I've replaced both woofers and ribbons (with extras in storage) and while a few new speakers seemed intriguing NONE could come close to recreating the viscral texture of real musicians in a real space (REAL close. As in studio mike distance......if that's how the recordings were engineered.) They are (sorry) a little under dynamic in the bottom octave. But still flatter, lower than anything up to 15 times their original retail. (I built custom subs with custom drivers. Cross 'em over LOW......) what they do in every other octave above makes the investment in building (or buying, but you should take care what you match them with) subs for them. I use Polk SDAs/monitors as surrounds with the Carvers as main L/R. I keep going out trying to find SOMETHING that will make me consider an upgrade and it KEEPS ON NOT HAPPENING. If you happen across a pair (Plats in particular) GRAB 'EM!!!

Presentation of sound stage, flat frequency response, very tight bass and lots of it, reproduction of human voice and strings, price to performance ratio

Barn Door Size, WAF (Wife Acceptance Factor), Discontinued, Very Power Hungry, Stabilizing Feet Sheer off Base very easily

Let me first say right up front when I purchased these speakers 13 years ago, they were one of the best buys in audio. Today, in my opinion, they still surpass anything in the under $12,000 range. I am perplexed when I read a post about how uneven the frequency response is. Many magazine reviews have documented with very sophisticated testing equipment the ruler flat frequency response of these speakers. I suggest whoever does not have a flat frequency response check upstream for any equipment or room acoustics issues. (The room can play havoc on speaker response without the proper sound treatment) My set up consists of powering these speakers with a Carver TFM 75 which delivers 750 watts of clean power. These are very hungry and need plenty of power to make them sing. The reproduction of the human voice by these speakers is uncanny. Check out the DVD James Taylor “Live at the Beacon Theatre” or Sara K on a Chesky CD. It doesn’t get much better unless you are willing to jump into the 5 figure range. Have I mentioned the sound of strings reproduced through this speakers? Pop in Yanni “Tribute” track 3 and look to the heavens at the sound of the solo violinist. They need lots of room to breathe to create the type of sound I am describing. My speaker placement consists of placing the far edge 5 ft. and the near edge 46 inches from the rear wall. I am also set in 42 inches from the side walls with a distance of 6 feet between the inside edge of the speakers. The ribbons are approx. 11 ft. apart and 13 ft. from my listening position. For separation purposes, I have the ribbons on the outside edge rather than on the inside edge. In my room, the flattest response is achieved with the bass control in the 3pm, mid-range in 3pm and high in 5 pm position. No need for a subwoofer here. Check out the Eagles “Hell Freezes Over” opening cut for gut wrenching bass. I had to re-caulk my glass transom over the entry door to stop it from rattling. The soundstage has to be heard to be believed. It paints the artists like on a canvas. Placement is exact and the ambience created by the dipole design is remarkable. These speakers never tend to shout the way a dynamic speaker will when played loudly. Therefore, it is very easy to get in the mid 95db range and not realize it. (Watch that hearing loss) No listener fatigue here. I find I always listen to Audio DVD’s in stereo because I have not found a center channel that reproduces the vocals as well as the Carvers. Can’t justify spending the same amount of money for just a center channel that I spent for the pair of Carvers. Because of the shear size of these “Barn Doors”, one must have a dedicated listening room. Otherwise, the WAF (Wife Acceptance Factor) becomes a serious issue. Fortunately, when we built our house years ago, a dedicated media room was a must. In closing, since these are no longer produced the only way to acquire this audio bargain of a lifetime is to search the used market. I cannot speak for the earlier renditions since my pair was the last series produced. (Platinum Amazing Mk IV) However, it is well worth the time and effort to pursue. Be forewarned-Need lots of power, plenty of space, room treatments, and if married, a dedicated listening room. Once this criteria is met, you will be in audiophile heaven for very little money. Don’t forget to re-caulk the transoms!!!

No subwoofer needed. The bass output capability of these speakers is incredible.

Time consuming to set up properly. Large room preferable. Because of their age I am fearful of having to obtain replacement surrounds for the woofers.

I am the original owner of the Carver Amazing Platinum, Mark IV version of these speakers. As far as I know, these were the last Platinums to be produced by Carver. The sound of these speakers is incredible, you really have to hear it to believe it. Because of my wide taste in music, I wanted a speaker that would sound warm and delicate with classical music and reproduce the dynamics without flaw, that would also give that live experience with rock and would be able to have bass necessary with Jazz. In other words, I wanted the perfect speaker. I looked long and hard and finally ended-up with the Carver Amazing Platinum Mark IV speakers. These speakers, in my opinion, are the best speakers ever made. I know that there are $100,000+ speakers out there, but lets be realistic, how many of us can acually afford to purchase them. I have even looked at the new Magnaplanars (the top of their line, at about $11,000) and would not part with my Carvers. The Carvers are truely a full range speaker. I don't understand why they were ever discontinued, but I hope that Bob Carver's new company, Sunfire, eventually reproduces these again. If you ever have the opportunity to purchase these speakers, buy them. You will not regret it.

Strengths of this speaker include looks, dipole characteristics, ability to play loud, resolution, coherence (at least down to the 150Hz crossover to the bass drivers) and dynamics.

Weakness would be size (they look like two black doors), need for almost unlimited power, lack of top end and the usual problem of matching a lightening fast ribbon with a dynamic woofer and complicated crossover network.

I purchased the Mark IV Carver Amazing Platinum speaker new in about 1994. Since then I have made some upgrades and changes. I added Harmonic technology resonance control devides to the body of the speaker near each woofer and small Marigo dots on the 12" woofers themselves. About 5 years ago I removed the Mark IV crossover and replaced it with an outboard Clearview crossover modified with improved transistors. I did this to better power the speakers by biamping and to ameliorate a dip in output (at least in my room) from about 230Hz to 550 Hz. I had very good success with this as it much improved the frequency response in that lower midrange area. The only negative result was a diminution in bass response. I was able to use my Parasound 2200 stereo amps in regular stereo mode instead of bridged which resulted in a more natural relaxed sound. The ribbon is the thing and is very clear and nuanced. I am able to immediately hear any improvement in the resolution of my source components. The speakers are positioned about 7' in front of a wall covered in Sonex 3" panels. This tweak quieted some distortion caused by hard reflected signals from the back wall. I also added a Musical Fidelity equalizer to boost the lower bass and upper treble. With these improvements the speaker is even less colored and has a smoother frequency response and better dynamics. Any audiophile who has had a speaker for 8 years has a bit of a bug to make an upgrade or change. I would like to figure out a way to give this speaker which begins to roll off at about 7kHz a top end and I would like to tighten and extend the bass. However with mods I have over 4k in these speakers and I would have to spend about double or more to achieve a significant improvement. Overall this speaker is just to good to replace easily. The combination of clarity, dynamics, ability to play loud or soft with good resolution and the top to bottom coherence of the ribbon are hard to beat. The Martin Logan Prodigy has more impactful bass and better integration of woofer and membrane but costs nearly 3x as much as my modified version. I can't be anything by happy though because people usually like the sound of my speakers very much and are impressed with the way the dipoles fill the room with sound equally loud right in front of the ribbon or off to the side or 15' away. I probably will try to further improve the sound of my speakers by upgrading my amps and figuring out some way to add a tweeter. I have continually upgraded my source components and cabling over the years but have never changed speakers so this may be the best recommendation a component can achieve. My source components are as follows Musical Fidelity Nu-Vista 3D CD player, Audible Illusion preamp, VPI Mark IV turntable, Eminent Technology ET-2 arm with Grado Sonata cartridge, HMS Gran Finale Top Match Box interconnect on CD player, Marigo interconnect on turntable, Cello Strings and Tara Decade interconnect to connect preamp to crossover and amps, Tara The One speaker cable on ribbon and welding cable on bass run.

I have auditioned MartinLogan Prodigy, various B&W loudspeakers, Magnepan 20R (briefly) and Avalon Edilons, but none on my system.

Great midrange and can listen hour hours and hours and they will go very loud (for a home hi-fi speaker). Very impressive to listen too when warmed up. Good midrange and treble dynamics.

Need a BIG high quality power amp and need to be warmed up to give their best (about 30 minutes). The ribon does not quite integrate into the 2 x 4 x 12" woofers, and the upper bass is a bit soft. They can be a little polite with rock. The ribon does not quite integrate into the 12" bass drivers quite as well as the other reviews suggest, but at this price who is complaining! They are heavy, so getting the right position is a little back straining.

I heard these speakers at a hi-fi show when they were launched in the UK. The Silver seems to be much less of a good deal than the Platignum. When looking to upgrade about three years ago and saw these in a hi-fi shop second hand. After a bit of haggling I got them for GBP 500 (about $800). They needed a lot of tweaking and effort to get them to sing, but once done, they are fabulous. The trouble was that they were so good they showed up the parts of my system that needed attention. The Krell KSA50Mk2 I was using at the time was just not up to driving them with enough authority. I was a bit surprised, but when I upgraded to a Krell KSA200B with new speaker cables there was a massive difference. This speaker really does lover POWER and the ability to drive very low impedence with ease. The KSA200B puts out 350W/8 Ohm, 700W/4 Ohm, 1400W/2 Ohm etc.. They are a bit polite for out and out rock and I have found that I now appreciate a more varied musical diet. I use them with a Rel sub, as I find that in my room the bass rolls off at about 30Hz when they are positioned to sound best. The Rel sub takes it down to 18Hz almost flat by my ears. The rest of my system is: Meridian 508 24 bit CD Rock Reference/Exhalibre/AT-OC9 turntable DNM 3A pre-amp (twin power supply version) Krell KSA200B Rel Stadium 2 Sub-woofer Cable Talk interconnects QED silver speaker cables They need to be used in a large room, I am lucky enough to have a 35'' by 19'' room with 9'' ceilings and this is only just big enough for them. I don''t think anybody who has listened to the system that has not liked the sound or even been indifferent. These speakers are worth the effort and are a bargain if you can find them. They do dominate the room visually, but they look so good this is not a problem in my eyes. I have a separate music room, so I don''t get any issues. I have looked around at more expensive speakers, but I have not found the same quality, dynamics and clarity at anything like the price. The Apogee Diva may be better at some things like integration, the Wilson Maxx has more dynamics, but has a sting at the top end and is very costly. The new Quad 989 is great, but can not go loud. This is the problem, where do you go from here without spending the price of a nice car or a house?

Crystal clear, never break-up. Deepest bass I have heard from ANY speaker with out the use of a subwoofer.

Can be power hungry on certain recordings, other than that, none.

I got the Platinum MK.IV's in 1991. Right out of the box, I knew my search was over. NOTHING I have ever owned can come close to the performance of these marvels. Anybody who got a pair when they were available was very fortunate. Something like this does not come along too often. I drive them with bridged Carver M4.0t and TFM-42 amps. They are identical amps rated at 375wpc@8ohms in stereo, 500wpc@4ohms in stereo, and 1,000watts in bridged mono operation (which is how I use them). These products have basically been "on" since I got them all (1992). The guy designed some great products, SOME, are no doubt, already "collectors" items. I know these speakers are.

Nothing compares

"WOW" factor. Accurate, transparent audio reproduction across entire audible spectrum. Light, airy soundstage.

Hard to find, BIG, heavy, power hungry, expensive to repair, need a BIG room & BIG amps to optimize these beautys.

I had purchased a pair of Infinity Preludes from Ubid last fall. After having FOUR PAIRS of these speakers totally destroyed in shipping (by both UPS and FedEx) over a period of 5 MONTHS, Ubid & I agreed it was hopeless. They refunded my money & I once again found myself looking for a good pair of mains.

I was "awestruck" when I had first seen & heard the "amazings" back in the mid 80s & had always vowed that one day I would have a pair. My dream finally came true a few weeks ago after 15 (or so) years of waiting.

I had looked at these same speakers approximately 2 years before. They weren't in the greatest of shape, & one of the subs was not working. Made him a low-ball offer which he turned down, then accepted, then turned down again. I was pissed.

Six months later they showed up for sale again. Seems about every 6 or 8 months they would come up for sale again. Well, I decided to go have a look again, since it had been almost 2 years. They looked much better than I remembered, or maybe I just wanted them a little more. They had been stored for a year, the sub had been fixed, and they were local- so I forked over $1125 & loaded them into my truck. He still had the original boxes & manual, which was a definite plus. Couldn't wait to get them hooked up. I was not disappointed.

I'm continually "amazed" by the impact & dynamics of the bass. The ribbons are "amazingly" smooth, sounding somewhat softer than Apogee & no Maggie "slam". The detailing is hypnotic. They're bi-wired right now, as he no longer had the jumpers. I plan to remedy the situation shortly by bi-amping them, as they're currently underpowered. Would like to set up a quartet of identical M-500's, all in mono configuration. It's a hoot to crank them up & watch the room lights flicker. Sound quality is definitely source-dependent. Really brings out the weaknesses in certain recordings. Sound stage is very sweet, & works well with Carver's Sonic Holography technology on instrumental recordings.

The prelude's were really nice- small footprint, video shielded, good frequency response, but a little forward in the midrange. Some recordings sounded overly harsh & became fatiguing over time. Great for home theater though.

Overall, I'm happy with my decision. Only hesitation is how they'd incorporate into a digital theater system. Hmmm.

Thank god I don't have to contend with the "wife factor". I'm in LOVE with these monsters.

Bought my platnums in 1993,from a friend who wanted to buy some Magnapan's. I stole them for $700.00. After about two months, he was wanting to buy them back. Never have heard a better speaker. Perfect soundstage and imaging. The bass is
overwhelming, and the highs from the ribbons is awe inspiring. Friends come over and just sit and smile!!! the Pplatinum's are power hungry, so I feed them 800 watts,
which make them nearly kick my house off the foundation. During high listening levels, the lights in my listening room actually dim a little!!!! Will never sell these speakers. Too bad they are no longer made.

Excellent sound

None

Purchased 1987 OR '88, they stand about 5 1/2 feet high, are black, and have no realistic comparison at 2-3 times the price. I drive them with a NAD7600 which should be able to put out over 600 watts/ channel into the 2 ohm impedance, according to the documentation. Thus I am able to apply about half of the power some reviewers have found possible; the sound level is quite sufficient. At the higher levels, most music causes various objects in the room to start making annoying sounds. Appreciating these speakers probably depends on the owners hearing; personally I have tested in the 99 percentile.
I cannot hear or see any problem with the ribbon element.
Certainly these speakers dominate a room. Far from being an appearance problem, these speakers draw awed comments from all visitors, and more so when something is played.
The only annoying aspect of my set-up is the NAD7600 which when turned on defaults to a low power setting. It was designed this way so that pedestrian speakers would not be destroyed. The NAD7600 was $1500 new at teh same time and is a real bargain for the power capability. I guess they are also out of business.
