Fine looking driver huh?
It is kind of funny... a lot of commercial products are using a $50 driver and charging in the thousands. We are using a $499 driver and charging just over a grand.
I'm specing our version of the Tumult with just a 4 Ohm tap and different connectors for the amp but otherwise it is identical to the picture.
In room we should get pretty flat down into the teens. It partially depends on if we use any EQ and if so, how much. Since it isn't a ported box we won't fall off like a brick wall though. One of the advantages of a sealed box alignment is that your 6db fall-off matches room gain. We are doing some testing/measuring next week so once we finalize a couple details I'll post some more information on the frequency response. I hope to get one off to a third party for some independent testing so that there is no doubt about our performance.
The Double is just two subs. It is for the people who just cannot get enough. Even in a very large room one of these is going to deliver a ton of bass. Two will get you more obviously and you often get a little smoother in room response due to having two sub locations. Also you get lower distortion because each sub doesn't have to work as hard. They are nice and compact so it wouldn't be too hard to stick one in each front corner.
There are two amps in consideration so I don't want to give specifics on the amp until we finalize on one of the two. Both have the standard plate amp crossovers and functions. Once the decision is made I'll post some pics and give some more specs. We are going to run some test on one of the two in consideration next week and if it measures close to the advertised specs we will use it. Both amps in consideration are 1000W Class D amps. The one we are testing next week is better quality than the stock AVA-250s used on the RAVA (fit and finish...we shall see on specs).
The sub will be down firing. One of the challenges of using a driver with this kind of excursion and weight was that front firing it would blow the grill right off the box. Also, having the weight and motion of the driver centered on the center of gravity of the box eliminated some stability concerns we had when using it front firing.
Overall I’m stoked… I think they are going to sell like crazy and the biggest concern I have is shipping a 140 lb. subwoofer. I think we are going to stick with crating them and using a freight carrier only.
