That is a really nice build. Insane its hitting so loud and such a low frequency. I agree with you Carl, if I had a large amount of cash available I'd invest in a crazy set up like that as well, just to be able to have one. Itd be kind of like a life's accomplishment.
But from the #'s posted, it looks pretty peaky. 150@ 22hz is SICK...but can't do 150 over 58hz, but does 156-57@30hz?
That boils down to a flawed box design (for daily/street bass), IMHO. Looks like the sealed side of that 4th order is a little too big.
Wouldn't you want flatter-ish response...that is, if you are looking for daily/street bass. Not a competition burp system?
Also, 48 $150 10's (at presale price, not sure on sticker price)? DAMMM!!!!!
(shameless plug) For instance, our DSP DDemo van w/ 10 DD2515 4th order. 150ish @20hz, 157-158dB at 40-80hz? Yes, that loud thru the whole range, and 7-8dB per octave roll off at 40hz aint bad Also, thats w/ only ~7-8kwrms. 161+ loaded to 0.2ohm....11kw
Guess we need to flood the interwebz w/ vids of the van once i get both amps installed
But, either way. SICK BUILD PEOPLE!!!! Huge respect from me! I love crazy loud musical systems!!!! There are VERY few out there.
What does one do when one wakes up? Grab a cup-of-joe, then while lightly stroking a puzzled chin say "....hhmmm, think I will put a pallet of sub woofers in my vehicle today... yeah that should do" . LOL LOL HA LMAO. Crazy, cool build.
