Figured I'd ask here as well since there's a lot of experience with Dayton Reference drivers.
I'm kicking around a couple of ideas for a new set of open baffle speakers, and one of the key things I want to try is a dipole woofer. At first I was thinking of trying a wideband driver for the mid, with XOs at 200 and say 4K. But now I'm leaning towards keeping my Audax PR170M0 mid, replacing the Fountek JP3.0 with say a BMS/DDS combo (so I can move the XO lower), and putting an OB/H/U frame woofer under it. This'll be on an active XO with probably a Behringer A500 on the woofers, so I don't need it to match the 95dB+ of the mid/tweeter combination. However, with a reasonable 16-18" baffle, the PR170M0 could be stretched to 300Hz, but it's happier at around 400.
So, I need a woofer that'll work up to that range, and can be used in an OB/H/U. I started out looking at Eminence Alpha 10s/12s, but then someone suggested the RSS315 as a good choice for a 200Hz XO, and more research turned up the RS270 as an option too (maybe 2 of them per side?). I'll have a monopole sub at the bottom, and I'd be OK with say 80Hz as the XO to the sub, so the woofer wouldn't need to go lower than that.
So... what can I realistically expect with either of those drivers on a 16-18" baffle, maybe with some shallow wings or a U/H design? With or without EQ? Wouldn't a 300-400Hz XO get into the range of the U/H cavity resonance? Any other drivers I should be looking at?
And I know, the best driver to do what I'm trying to do is a Lambda, but that's way outside my budget.
Thanks,
