I have:
1 pair Klipsch ksp400
1 Klipsch ksp-c6 center
1 Klipsch ksw 15
1 pair ksp-s6
All was purchased brand new and is still in boxes and never been opened and is up for sale!! Email me if interested at jssmitty517@gmail.com

I will start off by saying that if you ever find a pair of these, get them. They are impossible to find now and cannot really be sold on Ebay since they are so massive.

I owned a pair a few years ago and ended up selling, I seriously regret doing this. These are probably the best sounding pair of speakers I have ever owned, I remember being floored by the amount of effortless sound they put out.

I am a huge Klipsch fan but the horns can get a little harsh at times, not with these ones. They do not have the standard titanium or metal based tweeters. I had them Bi-Amped and they handled every bit of power I pumped into them.

There is an issue with the subwoofer amp, which is too bad, but it is repairable. The caps tended to swell and produce a hum, sooooo... replace the caps. The subs when working though will literally make you sick with the amount of output they have. If you need more bass than this then you should go to the doctor because you are probably completely deaf.

I will wrap this up by saying that my second favorite speaker I have owned is the Klipsch Chorus, and these KSP's are better by a long shot. A strange, rare, and nearly perfect speaker. If you can find an entire surround set then even better. I hope I can find another pair someday.

Well, here I am again to follow up on the Klipsch KSP 400 and KSP S6 and KSP C6 + Klipsch RSX4, RVX42 & SS.5 (presence/ambiance channels) & KSW 200 (rear channel sub) set up I have.

The sound is nothing short of breath-taking, LITERALLY.

Currently, my Livingroom gear set up consists of H&K Signature Series Amplifiers (1,5 and 2.1's), Marantz MM9000 amp, B&K Reference 50 S2 processor, Sony S5000ES BlueRay Player, Sony NS9100ES SACD/DVD Player, Harman Kardon DMC 1000 Digital Media Center, ADC SS 525X EQ (presence/ambiance channels), Yamaha DSP 3000 processor (for presence/ambiance channels), Tice Audio Power Block III Signature Series Power Condiitoner, Tice Solo Power Conditioner, NuReality Vivid 3D (presence/ambiance channels), 3 x Musical Fidelity X-10 V3 tube buffers, and a Sony Bravia EX700 60" LCD/LED HDTV.

All connections and main speaker cables are Monster Interlink MK300II & Interlink MK400 and Monster Z2 & Z3 speaker cables. The surrounds and sides are 10 & 12 AWG OFC speaker wires running through the ceiling and dropped, because I couldn't find Z series speakers cables long enough to meet the need (probably would have been cost prohibitive as well).

I have the HK Signature 1.5 amp powering the mid-bass drivers on the 2 x Klipsch KSP 400, the Marantz MM9000 powering the 4 x klipsch KSP S6 rear & side surround speakers, and HK Signature 2.1 amps powering the 2 x KSP C6 center speakers, 2 x tweeters of the KSP 400's and 9 x presence/ambiance speakers (4 x Klipsch RSX 4's, 1 x Klipsch RCX4, 4 x Klipsch SS.5's ) routed through the Yamaha DSP 3000 for additional realism. The Vivid 3D is connected before the DSP 3000 and adds more spatial expansiveness for the ambiance channels and I also use it to "sweeten" the ambiance channels a tad bit more (plus the active display is kool, but not distracting).

The 4 x Klipsch SS.5's are mounted above the 4 x Klipsch KSP S6's for side and rear ambiance channels. The 4 x Klipsch RSX4's are mounted above of which 2 x are mounted approx. 4 feet to either side of the Klipsch KSP 400's, and the 1 x Klipsch RVX42 (center presence/ambiance) is mounted above the 60" inch HDTV in between the two Klipsch KSP C6's.

Let me just say I have not yet heard another home system that surpasses the sound I am able to get from my current 17.3 speaker set up (and using 19 channels of amplification of the available 22 channels of amplification I have from 5 amplifiers since the KSP 400's are biamplified - the 3 x subwoofers are self powered). I have considered adding additional 2 side channels using Klipsch SS3's but I think that may be a tad too much.

Not trying to impress, but rather impress upon you the extent to which you can improve your aural listening pleasure, if you are willing to go that far (and I am).

The KSP series speakers have held up rather well, and the warmth of the mids coupled with the gentle (not searing), but detailed highs from the silk dome, horn loaded tweeters of the Klipsch KSP series and the thumping bass of the built-in 2 x 400W subs of the KSP 400 are so delicious, that once I sit and begin to listen, I have to sit for at least several hours and just soak up the bliss.

Friends and guests who have come over typically leave with a burning desire to put the money together for an immersive experience like that I was able to provide with my system. Really, when listening to music or watching a movie, you EXPERIENCE it... not just listen and watch. There is a DISTINCT difference, I tell you and once you experience it, nothing less will do.

I really like the KSP series from Klipsch, unlike other Klipsch series I have listened to, which can be a bit fatiguing due to the brightness of the highs. The fact that I have 3 x Musical Fidelity X10 V3 tube buffers through which the KSP 400's and the KSP C6's are filtered through may add some more warmth, but even without the buffers they sound phenomenal. Klipsch should have just improved upon these units instead of discontinuing them.

I personally like the KSP series better than any other Klipsch series I have auditioned, because of the liquid mids and detailed highs that do not over reach and the bass is friggin' AWESOME! If you can get the complete KSP series - DO IT! I guarantee you will not regret it.

Absolutely love them. Smooth and powerful. Unfortunately, we moved from the house where I had a dedicatied theater into a place where I now have to work with the "decorator". So...these are on the block. Anyone interested? Tiger Joe???

I bought a pair of these gorgeous black lacquer KSP-400s on eBay and drove over 800 miles to Los Angeles to pick them up because the cost of shipping via freight alone was around $850. Needless to say, I was not disappointed when I hooked them up to my system. I own other Klipsch speakers, namely the Synergy KSB 3.1 and KSB 2.1's paired with KSW 150 subwoofer. Other speakers I have owned or used in the past were Bose 901V, Bose 301s, and Technics SB-G500. I've spent many hours auditioning speakers such as Martin Logan, Polk, Boston Acoustics, Paradigm, Acoustic Research, JBL, and Infinity to name a few so I could educate my ears on what is considered "mid to hi-fi."

My current audio system consists of Harman Kardon Signature 2.0 preamp, Harman Kardon 2.1 Signature amp x 2 (4 channels of one HK 2.1 amp is used to bi-wire the KSP-400s), Harman Kardon PA5800 amp (additional presence channels), Denon DVD 5900 (excellent audio - uses Burr Brown) , ADC SS-525x, Fosgate Audionics DSL Model 3, 3A and 4 processors (excellent 7.3 capability - musicality far exceeds Lexicon MC-1. The only Lexicon that has a 7.3 capability is the MC-12), NuReality Vivid 3D processor, Technics SH-8040 Space Dimension Controller, DBX 400X Routing Switcher, Pioneer EX-9000 Dynamic Range Expander (similar to DBX 3BX), Pioneer SR-60 Reverberation Amplifier, Pioneer PL-L1000A Linear Tracking Turntable, SAE 5000A Impulse Noise Reduction, Akai GX-R88 Cassette Deck, Pioneer CT-S600 Cassette Deck, Klipsch KSP-400 (main), Klipsch KSP-C6 (center), Klipsch KSB 3.1 (rear), Klipsch KSB 2.1 (side), Klipsch SS-3, (front presence) Klipsch SS-.5 (rear presence), Klipsch KSW-150 (rear channel sub). I currently use 13 channels of amplification with 3 x 5-channel Harman Kardon amps, utilizing all Monster Interlink 300MkIIs, Monster Z3 Speaker cables, and Monster Ultra Definition Y-Adapters. With the current 9.3 setup, the overall imaging and soundstaging is unbelivably spectacular. I'm considering adding two more Klipsch SS-3s for side presence channels for a 11.3 speaker set-up in the near future to blow my mind(Presence speakers are mounted high - closer to the ceiling to give ambiance/headspace).

However, let me focus on the KSP-400s... the pride and joy of my speaker system. These very unique speakers sound so warm, and yet superbly detailed without a hint of edginess or harshness and the bass is so well-controlled and fast that it can arguably rival speakers costing three to four times the original MSRP and blow away anything else near that price range. The d'appolito arrangement of the upper range horn driver and its vertically flanking mid-range/mid-bass drivers is at the perfect level of my ears, and I have the KSP-C6 center speaker set up to maintain the exact upper range driver height of the KSP-400s. I have auditioned all varieties of music from classical jazz to trance in the last several months and everything in between through the KSP-400s. I have to say without a doubt, that these are some of the best speakers I have ever auditioned. The midrange is just so warm and sweet (those of you who own these speakers MUST bi-amplify and use high quality speaker cables to really make them breathe - the difference is most definitely audible) and it ties in so well with the upper octaves, that I find myself listening and soaking up the aural bliss for hours on end (to my wife's chagrin). MOSFET amplifiers are highly recommended with Klipsch speakers due to their "tubey" sound... the Harman Kardon Signature series amps are probably one of the BEST matches for Klipsch, as they tend to be on the warm side of neutral and put out prodigious amounts of current (100+Amps). I have 200 watts RMS feeding into each KSP-400's upper range horn driver and the midrange drivers. That plus the 100+ amp high current capability of the HK amp makes it a perfect match with the discrete 400W amp built into each subwoofer section of the KSP-400. There have been some complaints regarding a ground loop "hum" of the sub's amplifier. That is most likely due to the house wiring having an improper/dirty ground. You can easily fix that issue by using a 3 to 2 prong adapter and a good line conditioner for your components.

Anyway, now that my ears are thoroughly spoiled, I'll probably never give these babies up... rather, I'm on the hunt for another pair of KSP-400s, and a matching set of KSP-S6 surrounds so I can use the extra pairs as rear and side channels instead of the KSB 3.1s and KSB 2.1s in my current set up.

Klipsch made a big mistake discontinuing the KSP series, rather than improving upon them. Many of the other newer Klipschs I have recently auditioned just do not have the midrange warmth and the silky upper range detail without edginess or harshness as these units do. If you can find a well-cared for pair of KSP-400s, do not hesitate to snap them up! Your ears will thank you. However, beware of the amplifier "hum," as it could be an early warning sign of impending amp failure in which case, you'd have to find similar plate amps (modified 500W Sunfire amplifiers would be nice as were used in the AR1s).

Super bass, clear mids and highs, very n ice look.

Too much sound for my apartment, sure neighbors will start complaining soon.

I wanted to get a quality upgrade of my Yamaha front speakers and was looking for a pair of SF-2, but the salesman tried the SKPS-400's and left no place for doubt. Been using it for a couple of weeks and they sound incredible, the powered bass causes the whole apartment to vibrate, mids and highs are excellent. If you're thinking in buying these speakers, don't hesitate!

solid build, HEAVY! Keep those original boxes for moving!!! great everything. Great warranty. MADE IN THE USA!!!!!

none. buzz fix above...

Love them...great everything and looks too. Got 'em with the mahogany finish. A-B compared with Def.tech's. Went back and forth probably 20 times, these just had a "brighter", better defined sound! Got the matching center channel too and in my 20 x 16 "theatre" room it just blows everything away!!! I only keep the bass/LFE level @ 30% and i can't keep the ceiling and walls from rattling. THAT'S a problem!!! That "buzz" some people talk about can be fixed by simply putting a ground adaptor on each AC plug!

heavy (115lbs each), not cheap, can''t find them anymore

I LOVE these speakers. Started out having the dreaded buzz/hum from the powered subs which could only be fixed by sending in the amp and control panel to Klipsch. Kudos to Klipsch customer service and techies. Turns out it was a problem with the control panel not the amp. Now that the buzz is gone I''m happier than a pig in...mud. First thing you notice is the unbelievable pounding bass. Takes a little fiddling with the knobs and some burn in time to get it sounding right and tight. Can''t imagine anyone needing more bass than a pair of these 15" 500watt monsters. Next thing that amazed me was the incredible detail I''ve not heard from other speakers. My personal taste lies towards crisp detailed sound and hearing subtle nuances as opposed to warmth. The KSP-400s are great in that respect and yet are not harsh. To the guy who rated these a 1 based on an audition at a dealer, I don''t doubt you didn''t like what you heard. But many speakers sound like crap when they aren''t broken in, especially in a showroom. I''ve heard $8,000 speakers sound like crap under those circumstances

I did not buy these speakers. But, I had an audition them from a friend of mine. They are excellent for TH and music as well. You could get a good deal on buying them now, since Klipsch has discontinued this porduct line. You might find them on web stores, e.g. www.tatumelectronics.com, for around $1,200 - $1,300/pair. I've also seen somebody trying to get them for almost $2,000/pair on www.ubid.com ???.
