I have a pair of Infinity SM152 speakers and one of the 15" woofers is blown
and I'm trying to find a replacement driver. A new OEM driver is over $300
(CAD) so I am trying to find a generic speaker that will work. I've tried a
few already but they are not as effecient and the bass end up sounding very
weak from one side.

Does anyone have the specs for these old monsters? Specifically the wattage
rating and the SPL. Frequency response would also be helpfull

TIA

**Actually, what you really need are the T/S characteristics of the drivers.
You can do this, by using the good driver. How did you "blow" the driver?
Amp go DC?

I dont know for sure how I blew the driver, but I do know that I have come
home a couple of times and found that one of my teenage daughters friends
has cranked the bass up as high as it would go and all the stuff that
usually sit on the speakers is on the floor. (conversation:"how did this get
like this?""I dunno, wasn't me") The cone makes a rasping sound when you
move it by hand. No sound comes out of that driver when its hooked up.

What are the T/S charateristics and how do I determine them?

**Thiel/Small characteristics. Most decent driver manufacturers supply them,
with their products. You can measure the characteristics in your good
driver, or pay someone to do it for you. Once you've determined the specs,
you can then search for a suitable replacement. Unfortunately, to describe
the method by which you can measure the driver yourself, is well beyond the
scope of the news group. The procedure will take around 2 hours, it you have
some basic test equipment. If you have computerised equipment, it will take
around 10 minutes.

I assume the foam surrounds are still intact? Dumb question, I know, but if
the surrounds are shredded, it's possible that the speaker just isn't
aligned properly with the voice coil anymore, thus the rasping sound when
you move the cone.

Best bet would probably be to ask Infinity.

Kind of a long-shot as well, but you could try to measure the internal
dimensions of the cabinet and plug them into something like
http://www.partsexpress.com/webpage....WebPage_ID=100 and see if it
returns any results.
