A speaker physics question.

I think that thread got messed up in a transfer when the forum changed. The first post or so seems to be gone.

Sorry Buddy, I was thinking you were saying in general they won't sound good, Yes I understand the thunder will be down quite a bit from where they are now. But I do wish to get rid of that boxy sound. I don't know if the link I posted is messed up or not but it does still have a lot of good info in it and apparently a lot of others say that after putting the 604's in OB designs they were very pleased with the results.

Infinite baffles sound quite good when properly done. I'd want a sub though.

When you say sub do you mean like this 48 "? It's kinda small, I better get 4 :D

Yeah, that one!

You might want to use the backwave of the driver to put out more low frequency sound.

Yep, I had a thread bookmarked and it is no longer linked to the same URL.

How do those sound Westend?

I drew this up tonight. It's a 3/4 piece of MDF 24" x 36" with 2x3 frame, it has a 6.5 dia hole that the speaker goes through and has a clamping type of setup so your holding the speaker by the magnet. I wonder how bad the phase issues would be? I'm trying to get them as close as possible and This is about as close as you could physically get them I think. also trying to get the open sound of an open baffle along with some good bass. If anything else it it'll give you a good laugh. :D

That design allows the waves coming off the front and back to meet and cancel each other, turning the "baffle" into a stand.

How about half of an oak wine barrel (used for planters) with the open end facing the wall and the closed end facing forward with the speaker mounted in that?

So, if the horn or port is facing forwards, the sound coming out will have turned 180 degrees and be in faze with the speaker, and facing rewards will be out of faze and requires the sound to bounce off of the back wall 180 degrees to be in faze? How about these speakers with the ports or PR aimed out the sides, are they 90 degrees out of faze?

I dreamt up a folded horn kind of like your picture, but thought of a curved .75? dado slot cut into the sides and gluing three layers of .25? rubber conveyer belting to form pretty, gently curving pathways. I was going to do this to the front and back of the speaker and combine them at the front (which would be the bottom of yours), but the sound would still be out of faze with each other, so...instead of out the bottom, turn the one side another 180 degrees and below and in the same direction of the existing opening?
