Well guys (and gals)...
Sorry for the not-so-punctual update. But I've been busy...busy marveling at this thing //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif...
First of all I'd like to thank Mike for the amazing opportunity to demo such a great subwoofer.
Now, to get things started...
WOW. I opened the box, and that is all I said. This thing is massive, especially for a 12. Obviously, with quad stacked mags...and the gigantic motor...but pics do not do it justice. The clearance on this basket is a thing of glory...I mean view you get of the coil and top of the former...an the dual spiders is simply amazing. (get used to this word) //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
I was quite happy to get my hands on it, especially since I was going to be the first person to actually get to send it some power!!!! WOO! Although, I have less than perfect enclosures for the task. Oh well.
I basically dropped it in the box I have for my 15MT. Made a large baffle for a 12, and plopped it on top. The box is 4.6 cubes @32hz with 90in^2 of port.
To tell you, at first I had one MTX 1501d hooked up...and to tell the honest truth...I was sort of disappointed. Then again, I know this thing isn't the most efficient //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif. So, without hesitation, I went for some real power! The Power supplied by a pair of MTX 1501d's strapped @4ohms (each amp seeing a 2ohm load...read as 2500+ watts total).
WOW! wowowowowowowowow, this single 12 is REDICULOUS! I mean INSANE! The shear displacement capabilities are out of this world. It's obviously unlike any woofer I've experienced to date. The driver had no hints of any distortion, took whatever I threw at it and reproduced it with exact precision.
In this particular box (which is obviously not optimal) it struggled with higher bass.When I say struggled, I do not mean it struggled to produce it...I mean it struggle to produce it with as much enthusiasm as every other frequency. That's ok, that's why I have sealed mids with 13MM one-way xmax...and 200+rms per side //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif (My XXX mids). So I adjusted my xover to have the sub on 50hz HP @24 dB/oct slope.
Anyways, it's a great subwoofer. With LOADS of obivously LINEAR displacement capabilities. Give it power, and it will give you TONS of loving in forms you'd never imagine from a single 12. It's simply amazing.
In the few remaining days, I will try to see if I can throw it in a sealed enclosure. I'll update if necessary.
