Re: Acoustic Elegance dual 12" diy sub.....

I'm building it for prize. I know you were saying 110 litre total volume, but that cab would be way larger than Prize can handle, and I dont recommend a system Q that low in a sealed sub unless your aiming for IB territory (in which case these are costly drivers for that use), or have very capable mains you plan to run lower than 80hz.

Listening to it tonight though, its sounding very nice, and a quick test on a BR confirms that this is going to go nice an low with eq (which I have).

I'll keep this thread updated anyway, and get some graphs up when I can.

Re: Acoustic Elegance dual 12" diy sub.....

i cross close to 60hz, so my mains are of course capable to at least there. a pair of cerwin vega m100 towers. i always forget i have a bit of a big speaker fetish in comparison to some people.(Okay... most people.) Do these subs actually suffer in the 80hz+ end from a lower q?

Re: Acoustic Elegance dual 12" diy sub.....

any sealed sub will change as system Q lowers. I wouldnt call this suffering, its just the character of sound changes, and for most people that dont have big low mains, a low system Q will seem to lack the upper mid bass, and focus heavily on low clean output. A high system Q will be great for small sats, with its focus on upper sub bass punch, so its all about finding what works best for you IMO.

Of course, all of the above is open to individual preference as well. Prize is obviously trusting in me to deliver based on my opinion. When I deliver this in a weeks time (hopefully), I'm sure he will be happy to add his view of the final product.

Re: Acoustic Elegance dual 12" diy sub.....

Yup, i'm following it pretty closely so far, and am very excited at the thought of getting it in my room. (And, yeah, sorry for any confusion, Moonfly is building the sub for me). I think, if possible, some graphs would be very interesting indeed. I don't have the necessarys to run REW as i've no 'line in'. It all seems to be going well so far though Moonfly.

Re: Acoustic Elegance dual 12" diy sub.....

yeah i think the vegas have a factory rating of 107db/w and some decent 15 inch drivers in a rather large cab. 34x18x18... lol! although i'd say closer to 96db, and tuned for some 35-40hz. I guess i'm spoiled to have a signifcant other that lets me keep these giants.

It seems this is a very solid build. I'd love to hear but, but am stuck in Canada. lol.

So far its sounding pretty decent, but the lower driver is leaking air and it needs some eq'ing. There is better to come and I'm gonna give it a few days of testing before I get cracking on the finish.

Nice one mate. What sort of timescale do you think we're talking as regards the finish?
