I'M MOVING AND IF SOMEONE IS INTERESTED IN BUYING THE SM 105,SM85 AND SM CENTER CHANNEL PLEASE E-MAIL ME. ALL FOR 700$!!!

Tested these speakers out at an audio dealer. Tested them with a Bryan Adams CD going through a Carver receiver. At first they sounded great, but when real power was put through them (50 watts peak, 25 watts continuous), the woofer made a loud "CRACK". This turned me against these speakers and instead I bought a pair of JBL J2080s. The Infinitys are cosmetically great, but soundwise, I didn't like the harshness of the sound that was produced by them. It may have had something to do with how efficient this line of speakers is. In my opinion, the JBLs that I bought are far superior to the Infinitys, although the Infinitys would be great for a low powered system.

The SM 105 are of Infinity's "Studio Monitor" series and perform quite well.I bought them on sale at my former U.S. Air Force base's department store for about 3/5 of the MSRP. Not being of great income and constantly on the move, I searched for a mini system with good specifications, performance, and features for between 500 and 750 dollars. I found an Aiwa system boasting interesting specifications and bought it. About three months later the speakers' structures were vibrating so terribly that I could only listen to softest of music at the lowests of volume! Well, since the system boasted adequate power, I took advantage of a sale and bought the SM 105s. They feature a foam dome tweeter and a 10 inch woofer, about 35Hz - 27kHz, and 100 decibel sensitivity. Their finish is black oak veneer, feel very solid and appear to be of very high quality, even the speaker terminals look better than equivalent priced Cerwin Vegas, JBLs, Bose, etc. Since I'd be driving the SM 105s with a mini system (although rated at over 100 watts at 8 ohms) I knew I needed an efficient speaker, this was pivotal in my selection. Also, the listening room was my small apartment's living room, and neighbors notwithstanding, I like to play them loud - my musical preference being equally divided among Industrial, Dance/Techno/Trip-Hop and acoustic. To date, the SM 105s have maintained impressive integrity, especially when compared to a top of the line Kenwood rack system I owned a couple of years previous to the Aiwa system. Their sounstaging and imaging aren't great, and the bass can get a little whoofy, but the highs are crystal clear, if a little bright, and the bass is, overall, impressive; this in consideration of their size (large bookshelf, about 20x12x18 (HxWxL)) and price. I'm very satisfied with the SM 105s and strongly recommend them for anyone interested in playing non-critical, loud, controlled music. For home theater they also perform well. I have auditioned Infinity's Compositions Overture 3, and can say that I have been having odd, speaker based dreams as of late!

These speakers are a shambles. Expecting good sound from them, I hooked them up to a Denon integrated amplifier, and played some music through them. I quickly discovered the difference between crap speakers, and good speakers.
Compared to B&W P4's, which were originally on the Denon amp, these speakers are horribly bad. They have NO bass response, PA type midrange (ie loud and grating), and the treble is clear but completely unrealistic.

Obviously it is not fair to compare these speakers to such expensive other speakers, but it just goes to show that you get what you pay for. I highly recommend to anyone who is thinking about buying mid fi speakers like this to look at some better gear. These speakers would be fine if you didn't know any better, but they just pale into insignificance compared to a decent pair of 'good' speakers.

They are reputed to be loud. Yes that's true. They can hurt your ears. But the sad thing is that the bass doesn't play loud. It is only the screeching midrange and bright treble which put out high SPL. The bass was the laughing stock of my friends for a while. Off the Denon amp, it is very boomy and completely absent as far as low (<65Hz) goes. Then you try to get volume out of the 10" woofer, and the damn thing distorts like crazy. What a mess.

Also the pair that I was trying out were second hand and it's worth noting that the woofer's plastic edge, which surrounds it and bonds it to the box, had expanded for some reason, and now was letting air out. So pop up some bass and you could hear the air escaping like some sort of mad prisoner. So there goes the build quality...

In their defense, though, they sounded much better through some older, and less expensive gear. Through my 20 year old JVC amplifier, these speakers were actually rather good and seemed to put out resonable bass and clear midrange and treble. So a tip: Don't match these speakers up with unforgiving electronics as they don't like it very much.

IN CONCLUSION, these speakers' performance can be equaled by much smaller and better built speakers like B&W's etc costing about the same. Do not think that the 10" woofer means good bass, as it doesn't. The P4's have a 6.5" woofer and absolutely blow so many speakers away in bass response and quality just because of the build and design quality. These SM105's were just one of the victims of this assault.

Fine for casual listeners but really have NO redeeming features!
