Here is a bi-pole version that i drew up -- Scott is still building the prototype...
I'm looking forward to hearing it. This may be the best solution. Despite what some think of bipole speakers I've found them to be extraordinary when done correctly. My RS 40-1197 versions are still in regular use. My wife loves opera and the bipole 40-1197 reproduces the vocals in a very special way.

Default Bipoles

I am with you on that one Tim. I have made two sets of bipoles and absolutely love them both. You designed both of them and they seem to fit just right in my listening room. I really do hope to get into the shop tonight and Sunday to make some phase plugs and at least get a start on the 125st bipoles. I have some lovely lumber to work with. Based on the results I have from your other designs I am going to take a chance and go straight to a finished cabinet. Some how a nice looking cabinet seems to sound better? I hope to have something to take down to Victoria in June for Dave to enjoy.

Hmmmmmm that sounded like a commitment. Better be careful I willhave to come through.

Nuff said for now

I've not done any measurements of the bipole design so I can't say how the tweeter interaction will come down. Just be sure you (or Dave) can get to the XO.

Hmmmmmmmmmmm
I may never live that one down.
Apparently super short wires are a challenge for some. I had no trouble???
I will use a few more centimeters of wire so those with big mits can get at my handiwork...
I was quite proud of my work.

Nuff said for now

hey I was just wondering if anyone here had tested the tang band look-alike for this, the w4-655???
http://www.tb-speaker.com/detail/1208_03/w4-655sa.htm

at least they look similar, but the tang band only has half the xmax.

The similarities are in size and appearance but that's it. The differences go far beyond Xmax. Completely different motors and sound quality. Sonically, the TB doesn't come close to what the WR125 can do.

Timn8ter,

Any problem putting the port in the front? I need a design that will stand flush against the wall, and the Rosa may do the trick.

I don't see why that would be a problem and the bass should benefit with the wall re-enforcement. With the rear port I found placing the speakers about 2 feet from the wall worked best.
