Ive had these speakers since 1998 they have great sound. They were 200 each I bought the floor models I believe for about 100 each so I've had them about 12 years now you really don't need a sub with these. The only complaint is they are really too big for bookshelf speakers. And distort at hi volume I think it has a lot to do with receiver

Excellent imaging, good frequency response. Generally pleasurable to listen to.

Cabinet construction quality. Very fragile tweeter

People, today you are talking to a changed man. For years, I've been something of an audiophile snob, preferring the likes of harman/kardon, (pre-IAG) Wharfedale, and McIntosh to that of Sony, Pioneer, and (cringe) RadioShack. The Shack was fine for solder and the odd connector I could not wait to get from Parts Express, but I never took their audio gear seriously. Even when Stereo Review and Audio wrote up glowing reviews of their Pro LX series (with Linaeum HFD), I chalked it up to some odd grading scale... "Of course they sound better than a Yorx boom-box, but they can't touch my SB-7000A's" was my prevailing thought. Fast forward 7 years. This morning while running some errands, I came across a fund-raising bazaar. Sitting under one table were two sets of Optimus speakers: a pair of Pro LX-7's and a pair of Pro LX-8's. Asking price was $10 per pair, or "$15 for all four", as the kindly lady told me. I bought them all, figuring I could use the tweeters for some project or another. When I got home, I decided to connect them up to my h/k 680i receiver. This was basically an after thought and meant mostly to see if the tweeters still worked. Two words: Mein Gott! I would never have expected this degree of high-quality and pleasurable sound from RadioShack. Beautiful, airy highs. Strong, tight bass. The only area they are lacking in, sonically, is slightly diminished mid-range; it is actually nice on some of my recordings where the mid-range glares a little. Absolutely wonderful sound, and easily comparable to some of the best speakers I have heard in their size range. I would have gladly paid 100 times what I did for them. A quick peak "under the hood" explained some things. Woofers are no less than Danish-made Peerless drivers. High-quality film capacitors in the crossovers, and Toshiba-built Linaeum tweeters. Good internal bracing and internal dampening. The only reminder of their low-end heritage is the very cheesy 5/8th-inch thick particleboard cabinet. Better than many speakers (Bose 201/301's, Sony, and others), but in some ways keeping them back. So now I am on a quest to find the Pro LX-10's, which were apparently the flagship of the line, with dual 7-inch drivers and Linaeum tweeter. Fortunately, many audiophiles share my former view of the series, so I should still be able to nab them up on the cheap... They're RadioShack, after all

Hilariously good imaging from omnidirectional tweeter, large bookshelf design has ok bass extension, some neat design on rear porting of woofer internally, very little 'chuffing' at port at higher volumes (strange, but nice). Subjective: found works best with solid state gear; tweeter is so easy on the ears already, tube pre made it too feathery and unenjoyable. Very nice pitch and tone to instruments that I'm sensitive to: piano (needs more bass extension tho), violin, & sax. Sounds good on all except hard rock (no matter, I'm getting old)

Pitifully cheap box construction, large bookshelf for many, may be advertised as bookshelf, but this is best as a standmount speaker (too much rearward tweeter diffraction on bookshelf). Subjective: not good on heavy rock; omni directional tweeter sounds wrong for this kind of music.

I've gone into RS for a thing or two over the years and always been impressed with non-fatiguing sound of the Linaeum tweeter. Found this model on audioreview. Out of the box it's a 2 star. With mods it's a darn serious 4 star sound knocking on 5. It's 5 I give it (maybe 4.51)modded, but that's about what the ratings are on it on Audioreview these days. Like below reviewer, I stuffed it with Parts Express damping sheets...it looks nice, so I did it in AND out. Rewired with 10ga. cable. Put them on solid, sand filled 18" stands. Kept them 3' from back wall(important). Lined the corners with mortite rope caulk, stuffed with Parts Express poly fibrefill. Wow - what a difference! For kicks, I defeated internal crossover and biamp them electronically at 2.5K. No kidding, these are so non-fatiguing, they took my Vandersteens out of action. These are my main speakers now...and they are darn fine and cheap. Mods cost, maybe, $200 (with $90 stands included). Look forward to mating with a nice subwoofer someday. I think the Peerless woofer, once relieved of subterranean bass duties, will shine as a midrange.

Tweeter, imaging, soundstage, bang for the buck. radio shack speakers are great bargain for hobbists that like to tinker with their speakers.

cheap enclosure, needs dynamat and more insulation.weird size (too big for most bookshelfs

i bought these speakers from Radio Shack as a discontinued item. the sound from the tweeter is awesume. i did notice how close the woofer is to the tweeter. well, i mounted the tweeter module on the bottom of the speaker and reversed it. now the woofer sits on the bottom and the port is at the top. i also lined the enclosures with dynamat and stuffed them with insulation. also they were rewired with 10 gauge monster cable. these modifications cost about 40 bucks a speaker but yields a speaker competitive with ones costing 5 times as much

The tweeter is great on reproducing strings, especially harp, dulcimer, and other ringing instruments. Try playing a c.d. of Alan Stivell playing his celtic harp and you'll see what I mean.

Some dullness in midrange.

Placement is very important for these speakers. I have a small living room with no good place to position speakers. Nothing seemed to work, given that the speaker sound (as noted in other reviews)is very directional. You need to find the right position. I ended up placing mine in corners of the room, one behind a door, facing up, with the back of each speaker sitting on an upside-down plastic tub so that the speakers were off the floor. The result is excellent. Somehow the sound disperses beautifully throughout the room. I no longer had the feeling that the sound was "aimed" at me.

Stocked up on the LX-5's for surrounds and remotes.

great quality sound the highs are very clean and crisp

midrange is a little absent but not bad bass is not its strong point (with a velodyne sub who cares!) the build quality leaves a little to be desired. the backs of my speakers are visible so i touched them up with a little black satin oil based enamel and they look great now.

i have a whole Home theater setup with the Linaum tweeter designed speakers from radio shack. i have PRO -LX10's as my front, a pro -CS 5 center speaker, Pro -LX-8's as my surround speakers(awesum) and Pro lx 5's as my back surround complemented with a velodyne cht 15 subwoofer. wow i can blow away most of the setups at circuit city or best buy.

Awesome tweeter, Small

More low end would be nice

I've had my PRO LX-8 for almost a year now and I'm telling you for the price what a steal. I was able to pick up the last pair from radioshack. They were actully set up as demos so I didn't even get a box for 169.00. With a five
year warranty you'd have to be stupid not to pick up a set if you could still find a set. I've played everything from hip hop to country through them and I'm telling you I'm really impressed.

Highs,mid bass,and db.

none

I have used these fantastic speakers since @1996. At the time Radio Shack was selling the LX5's,they couldn't keep those in stock.The next time I went in they had the LX10,and the LX8's.I listened to the LX10's, but they sounded very boxy,the highs where of course fantastic,so I was steered toward the LX8's and I was astownded at the clearity of the highs,the lows,the mids and all for $100 each. There was nothing on the market that could come close to the lows for this price and the clearity.The piano sounds like a piano not a synthasized piano,the violin is crisp and clear,horns are warm not piercing,all my recordings are like new,I could hear Jimi hendrix chewing bubblegum to editing sounds(clicks)from Pink Floyd to pages being turned by an orchestra.They make everything sound great from Mozart to Beethoven to Simon&Garfunkle to Pantera...
........I have LX5II's for my rear channel & A matching Pro CS-5 center channel, wirth every penny and then some.
RADIO SHACK! BRING THE LX8'S BACK!
please!!!!

It's been over a year since i did my first review. These speakers still rock. Since then I found and bought the last two in the long island/nyc/staten island area. :-P They are that good! All my friends are amazed at how good they are for the price i paid. I am going to upgrade my reciever and debating what to get to go w/ these speakers. Probably a marantz sr7000, sony db940, or denon 3300. Get them if you can find them and save major cash.

These speakers are a steal! It took some hunting, but I just picked up a pair yesterday for $69 apiece. They are selling out fast, but if you can get your hands on a pair, they are worth every penny. First, let me say that I'm an audio fan on a budget. In fact, I purchased these to replace the main channels of my KLH home theater combo. Am I ever glad I did! And without the reviews on this site, I probably never would have even known about them. Thanks guys!These speakers have a nice, even sound, no holes or bumps that I could hear. The tweeters have a sweet airy quality that sounds really nice with acoustic or live music. Low bass is not the strong point of these speakers. They have enough bass to shake the floor, but a twelve-inch sub is definately in my future. Also, I have noticed slightly muddled mid-bass from these speakers, but I am at a loss for space, so these are right up against a wall. From the other reviews here, moving them away from the wall should improve this, as well as perhaps some fiber-fill. Another comforting thing about this speaker is it's fairly long five-year warranty.
On a side note (and at the risk of sounding like a salesperson), I've done some research and found out that the Optimus LX line is actually an OEM line made by Aurasound, makers of Aura car, home, and multimedia speakers. Since it seems that Rat Shack is phasing out most of the LX line, it is comforting to note that Aura makes their own line of speakers using the Lineaum tweeter called Line Source. Prices are high, but they seem to have higher build quality. And for those interested in computer speakers, Aura makes a very nice 3-piece set that is priced at $99. In fact, before I got the LX-8s, I used my Aura computer speakers to listen to music, and they sound about 3 times better than my KLH setup did. More info can be found at www.aurasound.com
To sum it up, it really is too bad that these speakers will be entirely sold out soon. These speakers at the original price of $199 each were probably a better-than-average deal, but the sound quality coupled with the amazing low clearance price right now is a very good deal. I almost feel like I ripped Radio Shack off :)
