I have an IDQ12 in a 1cf sealed box in the trunk, it has no punch at all, but plenty of bass below about 60hz.
In my last car I had an Infinity Perfect 10VQ which was between the front seats firing down in a .6 cuft sealed box. It hit hard and went plenty low for my music (mostly techno). My only complaint with it was that if I wasn't careful I would kill the speaker. Either I would blow out the surround or melt the voice coils. The speaker was rated for like 1400 watts - more than double what I had. but the sound was perfect for me.
In each case the sub was powered by about 600 watts at 4 ohms with a class a/b amp.
With the ten I could have it do 100hz+ no problem, and it was tight.
I am really disappointed with the IDQ12 in this configuration. If I cross it over much higher than 60hz it just doesn't add much. Luckily my 6.5's in the front doors have a pretty good kick, but . . .
The IDQ has more bass than I could ever need at super low frequencies - just no kick.
Is this a difference between a 12 and a 10 or is it my choice of speakers? I am ruling out placement to an extent because the 10 in its box in the middle of the room (in the house) hits and the 12 in its box doesn't.
If I add polyfill to the box that would make it worse right? Is my box too big?
I have heard so many rave reviews about the IDQ - is that only for 20-50hz?
I thought for sure it would be better than an Infinity 12.
I have not liked many of the JL speakers I have had. I killed a 10w3 and a 10w6 before putting in the infinity 10 which I prefered SQ wise - and it was less money.
I am considering getting the DIYMA 12, but i don't know if I want that much more weight in the back of my car and I heard it doesn't go very low?!?!?
Any suggestions?
Thanks!
BTW - the IDQ12 is a fairly old one. I don't know if there have been any changes over time. I bought it new around '99
