If you have been in front of one of the cabs, played one, than please criticize. If you have not, than I would be happy to send one to you for a week, you pay shipping one way and then have at it. Please check out the demo videos on the Revsound FB page or do some searching. There are enough out there now and they went through extensive testing before being released. Without firsthand knowledge of a piece of gear criticism has little foundation, is not justifiable and a bit unkind. Duke and I had a long discussion re X-max quite a few years ago. You can probably find that if you care to. Driver technology has come light years from where it was in the 60s when I first began building. If you're a 15 guy you, perhaps, would not be satisfied with 8s but they do have their place and are quite formidable when properly loaded; especially this driver. With kindest regards and respect, David Luke
Your 2x8 may indeed work for some folks - I don't doubt that. Your 8x8 will probably work for a lot of folks. In my case, I play only one gig that requires that I bring an amp (everything else I'm on in ears, and the PA handles the work). All I have to do at that gig is keep up with a harp or an acoustic piano, and I'm good - no drum set or anything, so the requirements are very modest.
I've done WinISD simulation of the speaker I use for this gig, and your 2x8 - I designed and built mine especially for this purpose. It's a 110, but it's got a Ciare driver in there with an xmax of 6 mm - 3x the xmax of the Celestion driver you use. It's got about 1.5 times the surface area of an 8. So, the volume displacement (how much low end the thing can push) is 4.5 times the amount of one of your 8's - 2.25 times the amount of your 2x8. I find the capabilites my speaker has to be adequate for that gig - it exceeds the modest requirements by enough that it doesn't strain to do its job,and I have some headroom if things get louder. I wouldn't want less capability, however. If I were playing with a drummer, no way would my speaker be up to the task.
The efficiency of the driver is equal to one of your 8's. So, your 2x8 has twice the efficiency (in mid band) compared to my little 1x10. Comparing the 40 Hz output (I simulated your 2.8 in WinISD), however, yours is less efficient at that frequency (it rolls off higher) - the volume of your cabinet appears to be about 26 liters, and with the best tuning (most 40 Hz output) I can get, it's about 6dB less efficient at that frequency than my 110. I like my speakers to "dig" - I want 40 Hz to come out nice and clean, with plenty of output capability.
So, in short, while others may like your 2x8, I won't take advantage of your offer - in my case, I like what I have, I know it works well for what I need it to do, and what you're offering would have less capability in terms of what's important to me. I'm sure one of your 8x8's would be more than adequate for the job acoustically, but I'll stick with my little 33 lb cabinet for now.
