- I've got six SM150's we bought about 5 years ago. They are driven from
- six 220 W/channel amps. Despite the wattage, it's rare that we drive
- them higher than 90 dB(A) SPL in our (dead but not anechoic) test
- chamber. But we've lost three tweeters and a fourth is starting to
- sound bad.
-
- When we first got the speakers, I had a pair connected to a breadboard
- circuit which developed an open and ruined my whole day. The sound
- brought people running from all over. I lost one tweeter then. OK, I
- deserved that, but the other speaker appeared to be fine. Since then I
- have been extremely careful and I can't think of any incidence of
- abuse.
-
- My group goes through a repair organization which takes care of
- replacing the drivers. I have yet to hear what the verdict was on any
- of these tweeters. Some of them might have been fixed under warranty.
- The distributor we bought the speakers from claimed that there was some
- sort of fluid they put on the speaker coil which would somehow prove
- whether the tweeter bought the farm due to misuse. Maybe it was green
- ink, like the stuff you use to improve the quality of CD's? 8-)
-
- I don't really like the sound of these speakers but we aren't likely to
- buy new ones real soon. Compared to some of the stuff we buy, these
- were cheap items (I think we paid about $350 each, and we've got a
- computer in the next room with a book value of about $100k) but they
- have high, uh, visibility...
-
- The tweeters on these are not EMITs but rather conventional dome
- types. I guess I've probably got some odd prejudices, but these
- speakers don't have any fiberglass (or equivalent) batting in them at
- all, and this just seems cheap somehow. They are ported (to the
- rear). The two midranges are wired in series. Yes, I know, they
- probably don't make these any more.
-
- I contacted Infinity about the tweeter burnouts. I asked them
- particularly about speaker fuses. They told me that I should consider
- buying their circuit breakers instead. These are about $25 apiece and
- are available for the tweeters and the midranges. This is a bit better
- than replacing the tweeters which are about $65 each. Looks like I
- might spring for the tweeter breakers and a couple of spare tweeters
- just in case. My repair organization is *slow*.
