Well, the last time Aperiodic was a popular means of implementing a sub for SQ was back.. around 1990-ish? And if you remember the subs of the day, back then - a 10mm Xmax was huge.
I'm just worried, expecially with that much power (these are quite efficient too), about the possibility of blowing apart a membrane...
...but, assuming you'll be building them yourself, that's just somethig else fun to experiment with, no need really even being constrained to the usual materials to sandwich in there, I suppose!
A more restrictive membrane would seem to also help - well - lower efficiency, if that's a plus, given all that power!
front loaded aperiodic because I have a trunk, in a rather huge fastback design vehicle, and it's purely being done for SQ. I have no care about SPL events, but I want the 2nd and 3rd order harmonic elimination of an AP membrane with the improved driver control it offers. Mainly two reasons. Better detail from the drivers, and because I can. I like AP enclosures with the right subs, partly because I listen to more complex music where detail is more important than volume, and I like a smooth blend from my 8" midbass to the 12" subs, instead of just something that's going to pound the car and listener to pieces.
Well, this is a great sub for "elimination of distortion" and "clarity and detail".
It would be interesting to combine that with an aperiodic install.
And it also offers you the possibility of trying the sub out in more traditional setups - try it out sealed, too, and compare...
...for SQ, personally I've always been a simple stuffed/sealed sort of guy.
With subs like these (even playing with Brahmas and XXX's) though, when "the sub itself" has certain distortion-eliminating properties, when you put that sub in an enclosure type that itself has certain distortion (blurring, if you will) properties, it becomes VERY interesting to listen to - a sub like this, in a "sq compromised" enclosure - even bandpass - still sounds cleaner than most subs in sealed boxes. It's an interesting thing to discover.
I even played with one in a high-tuned SPL-style box - something a friend of mine had knocked together - and I'll be damned if it STILL didn't sound clean, to the degree that you almost didn't notice the tremendous SPL peak that the box inherently created - or I should say, you almost bought it that the SPL peak 'must be in the recording'. Pretty cool.
My point is - you might experiment with this sub stuffed/sealed, and you might find it to be cleaner than your past experiences with Aperiodic setups!
Hopefully you'll tell us all how it goes, because I've definitely got my hands too full (and definitely no vehicle appropriate for it) to try an Aperiodic setup anytime soon. I'm curious though.
So any chance I can get on the waiting list for a pair of these?
Absolutely - I've got you mentally noted right now (I haven't mentioned it anywhere else, so it's easy to track interest right now
) - I'm going to be building a "priority list" of people like yourselves, make sure you guys get the royal treatment - I'll create something more official as we get closer to April/May.
