Sub DIY vs mass produced?

Is there anything that makes a mass produced sub better then something I could make myself? I want to add a pair of subs to my ht room & I would like to go with pair of 12's. I have a extra adcom gfa-5500 that I was going to use to power the speakers & possibly buy another gfa-5500. I was planning on using Image Dynamics IDQ12's for the speakers in a 4cu ft box tuned to about 20hz (that's what someone suggested I do).

IS there a reason a store bought mass produced sub would work better like a velodyne, JL or whatever?????

thanks

What crossover? Most HT?LFE subs come in about 100-120Hz.Will you be able to adjust their output to match the system,or will you be able to adjust via a processor/DVD with variable level?
I have had excellent results using the Dayton Reference drivers (HF,haven't played woth the HO versions).

If you want to beat or at least equal everything out there then you need one of these drivers.

I am going to try a paradigm x-30 for now. I was told to get a outlaw x-over (icbm1 or something like that) but I couldn't find one. So I am going to try the paradim x-over & I will see how it works.

& yea, mostly HT.... but if I can get it to blend properly for music I would use it along with my infinity kappa 8.1 vII's. So I want it to be very musical....

My girlfriend is actually moving in & we are combining our stereo's. Her receiver is about 8years newer then mine (I have a old Denon AVR-3000 & she has a yamaha something.... made is 1999 I beleive) & has sub volume controlls. She has 2 mirage 8 in powered subs & I think they sound horrible... boomy & no low end. I do plan on updating the receiver to something new withing a year or so (I want a processor but time will tell).... when that happends I might try to find one with a internal x-over but I am a ways from that.
More to discover
