That would be pretty high to be playing a driver as large as a 15" woofer. But it is possible to make with reach each other depending on the 15" driver.
Well, it's a rather heavy cone, strong'ish magnet, so probably not ideal. That combined with the U-frame speaks for a low crossover point. The U-frame will only be the depth of the driver, so not very deep.
You could get it down to around 800Hz if you are willing to give up some sensitivity.
I do not play very loud so it could be an option. Experiments will tell.
Thank you. I know there's quite a lot information about this design out there. It's just to find the right thread and post
The side wing length of the short wing depends on how high the driver is playing. If you box in a wavelength that is short enough to propagate within boxed in space then it will try to set up a cavity resonance. Rule of thumb is that if it is playing above 200Hz then you need to stick with an L shape using a long and very short side wing design. If playing below 200Hz only then it can be a full U shape.
Side wing lengths vary with application. I recommend measuring the response and seeing exactly what it is doing to dial it in.
Alright. Since it's for the mid/tweeter section, then I'll try L-shaped. I see you have added a small wing for the mid's in some of your designs and none for the tweeter. Why a small wing for the mid section?
Last question, long wing on the inside or outside? If a side wall is closer than optimal, my mind would say long wing on the inside, so you would benefit from the off axis cancellation towards the side wall. Correct?
