Overview:
I paid a paltry $12.75 for a pair of Phase Tech's off of Ebay. I've been a fan of their speakers and have owed many of them over the last 15 years. Some of them have been good and some bad, but these are the cream of the crop.
Looks:
They have to be some of the ugliest most generic and unassuming speakers I have ever owned. They are basically a generic black box with generic looking black drivers. They also have cheap spring clips in the back and a nasty looking vinyl finish.
Sound:
They make music come alive. I would caracterize them as lively and forward sounding. different than any other Phase Tech speaker I've ever owned. They have rythmn and pace and image very well. Voices are upfront and highly intelligible. They are neutral in tone. Music is alive and engaging.
Comparison:
VS. Phase Tech 7t. The 7T's sound flat and two dimensional in comparison. The midrange is compressed and bass is one notey. Winner 3t by a wide margin.
VS. PC 1.1II. The 1.1II's cost $880 new. They are richer sounding than the 3t's, go much lower, and have a better high end. They are not as musical as the 3t's and are tougher to tame. Their bass output is tough to control. Alone the 1.1II are a five star speaker, but they don't have the magic that the 3t's possess.
Summary:
A very very good speaker, one of the great unknowns in audio. I'm looking for another pair.

I am a student at Michigan State University. My budget after paying for school is very limited. I spend almost every extra dime on my system. The Phase Tech 3.5s are the most underated speakers on the market. Many poeple I talk to have never even heard of them. They are incredible. I have a Denon Avr2800 running them, with the phase tech power10 sub wired with the speaker levek inputs. Dire Straits new HDCD sounds absolutely incredible on it. With the sub taking over most of the lows the 3.5s are free to play the mids and highs with incredible ease. Dolby digital also sounds great, the 2800's ability to dtermine where the LFE signals are sent allows me to play crystal clear DD and DTS surround without using the sub preout. These speakers are a must have for the budget minded audio nut.

I just replaced my 20yr old system with new Tetro 3.5 bookshelf speakers as well as the Octave 10" subwoofer and Center speaker. I did not know what to expect replacing my BIG Sansui (w/12" woofers) with these tiny bookshelf's, but I am extremely satisfied. They are a huge step up from my old speakers that I became accustomed to, the Tetro's have very pleasant full range sound. The are not too fussy about placement either with the 1" soft dome tweeter. They seem a little "bright", but turning down the treble a notch or two brings it down to a very realistic voice reproducing sound. If I close my eyes I can almost see David Crosby sitting in my living room. These speakers deserve more notoriety. I've never heard of them before, but the salesman at Columbia AV said that they were a great value. I paid $260(plus sub and center) for the pair and am extremely happy with the sound ($770 for all speakers). They don't look half bad either on the new stands that I purchased. These speakers are an extremely good value for the money. They far exceeded my expectations and really exploit the clean sound that my Sony DA30ES($750) reciever can deliver. They come with a 5year warranty. Phase Tech is very selective about the relailers who sell their speakers, so you might not find these speakers at the large discount stores.

I bought the 3.5 bookshelf speakers along with a center speaker from Phase Technology and a 10" subwoofer about 3 weeks ago. The speakers sound awesome, especially music with individual instrument (guitar, cello, sax) or vocals. The speakers produce extremely good clarity and presents. The only problem I has was setting up the subwoofer. I thought I needed to turn up the bass to full power since I only purchased the 10" for my 12X20 listening room, but it sounded too "boomy" and I did not like it. After several attempts to adjust my recievers EQ settings, I got smart and turned the level on the sub down to 1/2 and now my bass is perfect. I got a great deal on the bookshelf speakers and did not spend an arm and a leg to get excellent sound quality. I am not qualified to compare these speakers to any of the really expensive speakers available out there, but I used to own a pair of Bose 901 speakers that I always enjoyed listening to, and these blow them away with clarity. I recommend these speakers for both quality and value. Check out my review of my new reciever if you want to. http://www.audioreview.com/reviews/Receiver/Sony_STR-DA30ES.shtml

I was recently shopping around to replace my old system (about 10yrs old) with some good quality low priced speakers. I compared these to jbl TLX-171 and 181's, definitive tech's bp 6 and 8, jbl HLS series(can't remember the model #)a Boston acoustic bookshelf, a definitive tech bookshelf, and cervin-vega re-50's. I found the jbl's to be very nice speakers BUT they were lacking in reproduction of voices both female and male. (something that you can expect from a metal dome)plus the 181's were very boomy with their 10 inch driver. dEfinitive tech's bp series also produced very good highs but were lacking in the human voice reproduction. the bass off of the bp-6 model was very similar in response characteristics of the 3.5's which is suprising, becuase the definitive's are floorstanding. jbl hls series was far too boomy and the cone tweeter was definatly a mistake on jbl's part. (this was a common trend among all HLS models) the boston's produced decent sound from a bookshelf but had a drop of in the mid range bass. the definitive tech model i auditioned had a very large soundscape but the highs were not balanced with the output from the woofer, they were far to bright. the cervins were a very nive speaker but were ridiculouse in size. they use an enormouse woofer 12" or so, needless to say they are UGLY. plus they are about 150 dollars more. the teatro's definatly came out on top when teamed with a sub. (Yamaha's YST-SW80)the soft dome on these speakers produced very sweet human voices but didn't loose much from the characteristics of a metal dome, a little bit less shimmer. they produce good bass from about 60Hz, very smooth and not punchy like some other models. when teamed with the sub crossed over at about 90Hz they sound exceptional. a definate best buy.
