I had a great time at the soundoff on Saturday - Chris's new bass bins sounded very impresive and show that you can do good things with 15 inch drivers in the bass range.
So here's a question. Does anyone think there would be interest in a sub designed specifically to go with HD15s, that is more sensitive than X1 (at the expense of not going as low), stacks neatly with HD15s and uses the same 15 inch driver that HD15 uses?
I expect 1550 would be OK.I'm hoping that I can design for whatever people are already using in their HD15s. That way, they only have to keep stock of one driver. Then you can play "mix and match" if you have say 10 HD15 cabs, 10 SD15 cabs and 10 drivers, you can move the drivers between the cabs. Or something. But a bandpass design will be fussier about using different drivers than HD15 is.
I'd also need to collaborate with someone who fancies building a prototype. I won't post designs before prototypes have been made due to the "controversy" that causes...
a wicked one modded for 15's would be the obvious solution as it works on the same principles as a hd15 and is just tuned much lower...a WOwith 12's would work but i reckon you could make a 15 version that was 2ft x 3.5-4ft x 1.5ft which would make it a more sensible cab size for moving and stacking etc...
Looking at specs, PD.154 looks like it will be the main driver, with the Fane as an alternative since its specs are quite similar. The Eminence has a 3 inch VC which rules it out completely. The JBL might be suitable, but seriously, who buys JBL drivers for anything other than replacements?
PS on first glance, the 1550 looks less suitable for this box than the 154, and since it's not in the list of recommended drivers for HD15, I'll rule it out. If there aren't enough bass bins for 1550, well, that's a different project.
