Super MWM

Recommended Posts

Thanks for the feedback, guys. I am going to look for a pair of these for now. Seems like a good first option to try, without building anything. I'll post in the classifieds.

If anyone knows anyone selling these, please send them my way!

Yes, it's called a Quarter Pie, since I designed that and the Super MWM. The quarter pies uses roughtly the same corner space as an FH-1 and is flat to 50 Hz. instead of 90. It's only a 90-135 degree single fold but I never used it past about 300-400 Hz. Very easy build.

Thinking about making a set that is van portable where the S-MWM's are not. Oh and they will go deeper.

ClaudeJ1,

that Q.Pie looks pretty intriguing to me so I am starting to seriously consider it or a variation of.

Questions:

What is the horn flare rate/type? Is such a fast opening profile necessary or just for ease of building?  I ask because I don't have my mid horns in the corners so the Q.Pies would be pulled out into the room, right underneath the mids, where the FH1 is now (potentially, just visualizing at this point). 

What driver/horn/crossover type did you use above the Q.Pie?

 

thanks!

And conveniently uses a 4 x 8 sheet of plywood for the top and bottom.

Almost like a plan isn't it. The length may vary depending on what Claude has to say. I don't want the top end of the horn to be below where I need to crossover.

Has anyone built these yet besides me? I sent plans out but have heard nothing back yet.

As soon as I get a construction/building/office built, I will.  Just trying to get by until the market settles out so I'm not $50,000 to deep into the build.  Currently, trying to work with what I have, doesn't leave room for the sets I already own.

Room is an issue for me as well.  I'm tapped out with the relatively small space I have for toys at home.

Local best source for 25mm Baltic Birch tells me 60" x 60" not available. 4' x 8' is but has gone up to $118.59 from $76 a year ago. I think I might drift up there and get a pile.

I bought 2 drivers (eminence kappa 15c) for a super MWM build. Felt I could do a decent job after what I learned from the pair of f20 subs that I built. As typical with life, I’m trying to finish a degree and we’re finishing our basement for extra living space. Hoping to do a build this fall/winter. Already running the K402’s on Peavey FH-1’s.. I’m halfway there!

You could point them out your garage door... at the neighbors.

I already have some big EVs and 396s in there for that.
