Infinity SM-112 Ideas?

[Zax1108]

So a co-worker of mine sold me a set of infinity SM-112 speaker towers for 50 bucks for the set. The woofers where damaged so he knocked off another 10. Real nice guy.

At any rate, I have plans to install new JBL woofers into the two towers the cross over system seems to be in good shape and the high and mid drivers are also in good shape.

Are they worth the new bass drivers or not really?

I have bose and klipsch THX line speakers for movies and hopped to use the infinitys for music.

But if they are going to take up more room then they will fill with sound I'd rather not put the work into them.

How are the stock woofers "damaged"? If it's merely the foam surround on the woofers that's bad, they can be repaired. Otherwise it's a hit or miss proposition swapping in woofers from another speaker.

Infinity's SM series speakers were conceived to compete with the Cerwin Vega speakers of the same era, and were designed to be affordable, easy to drive, and play loud. They make good party speakers, but not much else. Unfortunately, the SM's are not among the more desirable vintage Infinity's, all of which feature the famous EMIT tweeter. If you want some speakers around which to build a quality music playback system, I would look elsewhere.

They are very efficient, swapping in a new set of woofers is do-able, IF you get ones that are the same efficiency as the originals.

I had a set of the 15" version, one woofer had been hit by a basketball such that it worked OK at low levels, but the bent cone would cause all sorts of noise when it was pushed. I tried to swap in some JBL 2235H, thinking the box volume was just about right for them, only to find that the mid & tweeter level controls did not have enough range to balance them. I then tried a pair of 2225H's, which worked much better. And the mids and tweeters will keep up with a good woofer, they do get loud!

I ended up selling them with the original woofers to a guy that wanted to replace with JBL 2225H's...

Doing some research on them to find the efficiency rating, then finding a pair of woofers with that rating will get you in the ballpark.

I'm thinking there must be some Dayton or Eminence 12" woofer that will match up, I wouldn't spend a lot on JBL 2206's for that model, for one thing the cabinets are built like a drum...
