I heard them at a thrift shop playing background music. They are worth maybe $30 and are very difficult to sell. BTW, the sound manages to be boomy and dull at the same time.

Well I was kinda hoping for a RUN NOW response. I don't really need more speakers, but if they were the deal of the century I might be persuaded. It is the disease kicking in again I suppose. I still have a few days to think about it and get other responses. Your response was very much like the others. It was also recommended by the others to use these with a sub woofer...huh? Besides I do not own one anyway and would not expect to have to use one with 10" woofers anyway. It is a 30 mile road trip, which is not bad, but again I was looking for that RUN DON'T WALK responce . Thanks for the info.

They're not really hi end or anything but if you can get a decent price they'd be worth playing with. I think there are some simple mods you could do that would make them sound vastly better- add some filler/dampening material and add internal bracing.

Do NOT buy under any circumstances.
look for older RS line.
Right! I've heard the SM-152 and owned the SM-122 and they are better than the 2-way (IIRC) SM-112, which is not saying much. Boomy with muddy mids and highs are rare in "serious" speakers.

I'll away thanks
Thanks all...they were offered at $59pr. I will take your advice. I was under the impression that Infinity were good speakers. Just not the right model line I suppose. I actually have a pair of 6 1/2'' infinities in my tundra. The polypropylene cone had actually separated from the rubber surround after only a few years. Where they are mounted they were not even subjected to UV either.

Infinity quality has gone downhill very quickly, this includes their car audio.

Yes to the car audio too
Bought Infinity speakers for my truck and they fell apart in less than a year.
New Alpines been going strong ever since!
Which is a shame. I have some of the old green quartz cone Kappa components and the matching 12" sub that have followed me through several vehicles over the past decade and still sound incredible.

Infinity SM speakers under 150 are not all that well thought of. At the 150 and above they are OK. None of the SM line is up to the quality of the big classic Infinities, the Kappas or the RS series. The SM150 and up can be made better with work like cab bracing and additional dampening. The smaller ones are not worth the asking price you mentioned

Opinion
I combined the SM112 with some Klipsch rf10 that I bought for $60. They had been dropped and broke off one of the binding posts on each speaker (easy fix). I also found an M&K MX-90 with a little cabinet damage, but amplifier and speakers in great shape for $50. The kilpsch support the Infinity in the mid base area and the M&K takes over below 60hz. The upper end of the infinity are very good and clear. I know that many true audiophiles are present and might disagree, but many good sounding systems can be had relatively cheaply. I have a klipsch rf7 system at my real home, but due to work I am staying in an apartment and need something to listen to while I am away from home. As always it is your ears which need to be happy, you aren't here to please me.

Old thread, I know, but for anyone coming here for info like I do... Don't understand the hate that these get. I bought a pair that were in pristine condition, ($30) and re-foamed the woofers. I have many pairs of speakers, including JBL L-100, Sony SS-TL5, Pioneer CS-99A, and many Sansui SP series, etc... Just stating this, so you have an idea of what I've heard and am comparing them to. These are currently hooked up to my Sansui 8080, and I think they sound pretty dang good. A little lacking in the bass, but not bad at all. The cabinets and grills are beautiful on mine. I have them paired with a set of Wharfedale XP-2 at the moment. I did research them before I bought them - had they not been as cheap as they were, I would've passed based on the info I found. Now that they are re-foamed and I've heard them, I think they deserve better than what I've read. I've cranked them up pretty good on the 8080, and using no eq and just the tone controls on the mighty Sansui, I'm impressed with them. They sound clear and detailed, to me. They don't distort at volume, and the bass gets better as you add more power. Not a bad speaker, for what you can get them for. I wouldn't part with mine for any less than $150-$200, now that they are fixed. I've had a couple opportunities to sell them to buddies already. They sure are lookers.

I know these posts are aged a bit. But here goes. The "Infinity SM Series" are not infinity designed speakers. These are all Dr Sydney Harmon idea. The SM are a high output speaker with 4 order cabinets bracing does help, but any dampening make everything muddy. They are not in the same league as the Kappa of the early 80s, or even the RS 000/0001. They are made as a loud speaker, I will take Klipsch from the same era . I sold a lot of the SM at Highland Super stores in the Day. Late 80s, when 100 watt amps and receivers finally because affordable. Do not put any off brand drivers in them. they sound ever worse. Infinity made a lot of cash or should I say Harmon international, infinity owners. If you are willing to redesign the Crossover , and brace the hell out of the cabinets, I have seen some very respectable sound. But the cost is more that the original cost of the speakers(no one sold these at MSRP, ) $650 list were sold at $499.00. Ah the days of power speakers. It was fun.
One think I forgot to add , the original SM100 , made in 75 did not stay around long. 75/76, it was the only 8ohm infinity I could find from the 70s, I read what I could find on the design, it was mostly to be a home band speaker , loud bass, loud treble, not clean as all the others infinity. Seems that DR Harmon wanted to make some easy money in the mid to late 80s. Some facts, some personal opinion.

I have a set of SM-115's, they aren't junk but could be better. I did add 4 braces each from the baffles just behind the woofers screw mount to the back of the cabinets. There are gussets from the backs to the sides from the factory but more bracing wouldn't hurt any.
Just out of curiosity, what crossover rebuild would be required, do you have specs? Who knows, maybe some day...
