blew my sub
I guess I was feeding my IDQ10 sub too many watts because it now can't
produce even moderate levels of bass without distorting. I've tested it with a home amplifier just to make sure and it sounds equally as bad. It puts out like a whizzing/tweeting noise constantly and can't get loud at all. I think my amp was giving it 360W which is 110W over its recommended RMS level and I didn't turn the gain down enough to compensate. It sounded great when it worked. From inspecting, there doesn't seem to be any visible damage to the coils or the cone. I'm now considering getting a different sub, one that can handle a bit more power. I was thinking of the Infinity Perfect 10.1 which I've heard in a friend's car. It's rated for 350W RMS so I think I'd be okay with that. At least that way I can still use my ten inch box. :\ Don |

Tough luck. What amp is it anyway? Oh yeah, I wouldn't expect the Infinity to handle any more power than the IDQ10. Is the IDQ10 still under warranty, or did you buy it online? |

The amp was an MTX404 which I thought would be providing 200W bridged but
it was underrated by quite a bit and put out 360W. I bought the sub from infinitecaraudio.com and they claim they warranty the sub for 2 years, so I'll see what they say my options are. Can you recommend another 10 inch sub that would do better than the Infinity Perfect 10.1 for under $200? I'd like to not have to worry about overpowering it with 360W. Thanks, Don J.

Well, first of all, ignore power ratings. You can't compare between brands. Second of all, even if your amp truly can deliver 360wrms, you may have been delivering more than that to the speaker if you were driving the amp into clipping. A high-powered 10 shouldn't be too difficult to find. I'd just take a replacement IDQ10 if it's truly covered under warranty. Otherwise, just grab anything. There are a zillion out there. |

How does your amplifier feel about all of this, Is it still working ? Hooking up a blown sub to yet another amplifier could of resulted in one hell of a bad day.

The reason I was looking at the Infinity Perfect 10.1 is because it is
rated higher (350W/1400W) and a few reviewers at Sounddomain say it can actually take 350-400W RMS. I know you said powr ratings are useless but there were also reviews for the IDQ10 where people said to be careful with the gains when feeding it 300W RMS. The Perfect 10.1 is supposedly more sensitive (94 dB compared to 89 dB for the IDQ10) so I assume I wouldn't have to feed it as much power to get the level of output I'm after. I was also looking at the Elemental Designs e1OO.44/14 or the e10K.44/14. I'll see what infinitecaraudio says about the warranty for my IDQ.

That's odd about the power handling with the IDQ. I fed an IDQ12 over 800
watts from a bridged Kicker ZR600 for over a year with no problems.

I would have hoped subwoofer sensitivity ratings might have been measured, hmmmm, I dunno...maybe somewhere in the subwoofer frequency range? Just a thought... Tony -- What's more likely? That an all-powerful mysterious god created the universe and then decided not to give any proof of his existence? Or, that he simply doesn't exist at all?

I would have hoped subwoofer sensitivity ratings might have been measured, hmmmm, I dunno...maybe somewhere in the subwoofer frequency range? Just a thought... Rarely. On reputable woofers, you'll see the sensitivity listed as "87 db @ 200 hz" or some such, but in most cases sensitivity is db of spl with 1 watt of input power played at 1 kHz measured from 1 meter directly in front of the woofer. If you think about it, very few "subs" are actually purpose designed bass drivers. Most are simply loudspeakers which have been optimized for high power input. What we have for 12" subs are often used by sound reinforcement guys as a midrange. -- thelizman teamROCS Car Audio Forums http://www.teamrocs.com/caraudio/ teamROCS Car Audio News http://www.teamrocs.com/news/ "It's about the music, stupid" This post is Copyright (C) 2004.

He may have just gotten a bum sub.
Hopefully they won't give him crap about replacement. "Paul Vina" wrote in message news:YfpYb.337631$xy6.1674410@attbi_s02... That's odd about the power handling with the IDQ.

Well Infinitecaraudio is letting me send the sub back to get examined and
repaired by ID. On the phone the guy told me I was probably giving it too much power but I explained I was only using an MTX404 rated for 200W bridged. I said it was likely giving it closer to 250W but that is its recommended RMS rating. Hopefully it won't take them too long to get a working one back to me.

I don't think you're overpowering your IDQ10. My IDQ12 has been living on a
steady diet of a bridged 900 watt Zapco amp for years now.

If you're still paying attention to this thread, Paul, I'm curious as to
whether you had to keep the gain turned low with this kind of power. If I'm pushing 360W RMS to an IDQ10 I'm wondering if the gain turned all the way up would be bad. Forgive my lack of knowledge--I'm still in the learning stages. Don On Tue, 17 Feb 2004 14:08:56 +0000, Paul Vina wrote: That's odd about the power handling with the IDQ.

I never really paid attention to where it was set. It was higher with the
single 12 than with the 3 10 or 2 12 setups but if you keep an ear out you can hear when you're overdriving your sub.
