Hey everyone,
I have been thinking about building a new set of speakers and was toying around with the idea of a 3 way, with an open baffle midrange (about 150-10khz) My question is on the midrange, will there be phase cancellation if they are too close to the wall?
Thanks

With just the higher frequencies and shorter wavelengths you could get by with a narrower baffle. So with the narrower baffle the speaker could be closer to the wall.
what mid do you have in mind?
10kHz upper crossover requires very small mid
small mid will struggle to start at 150Hz on open baffle
trust me
I was thinking of the Dayton 4" driver https://www.parts-express.com/pedocs/specs/295-369--rsp100p-4-spec-sheet.pdf
Crossovers are by no means determined yet. Maybe 300hz would be more suitable? Any estimates on how wide the baffle should be and how far from the wall?
Thanks

The Linkwitz Lab site is worth studying. 3 feet is considered the minimum distance from the front wall. I wondered whether there was a maximum distance so started this thread, there is some interesting discussion Open baffle maximum distance from front wall
xxlimm4,
open back midrange is a nice idea, but implementation in real world is mission impossible. Sound wavelength is the key and dipoles are really difficult to make working linearly for more than 2 octaves. You are asking for 6 octaves!
Dipole speakers are 4-way constructions nowdays, and besides Linkwitz check also Kreskowsky and his Tech studies to find out why it is so. NaO Note Design Objectives
The question about minimum distance to front wall is interesting, but difficult. We must consider also frequency range/wavelength, wall absortion, listening distance, side walls etc. There is no single right answer.

For baffle size (..check mark the dipole option and make sure that compensation is NOT checked).
