Default Is there a way to build an open baffle ->b<-ipole? Does it make sense?

Hi all!

I was wondering... and did a search, and didn't find anything conclusive about the subject.

I have 4 Tang Band 4" W4-1337 drivers. I was thinking about building bipolar speakers in a closed box configuration. But then I read about how wonderful open baffle speakers sounded, and thought about building a pair of them. But apparently, bass cancellation will make the whole project moot.

And then I thought about building two open baffles, placing them back to back, and run them in parallel.

Would this take care of bass cancellation, and help me get the benefit of an open baffle configuration? Or is this idea just too dumb?

Default I'll take a shot at it...

Assuming the baffles of which you speak are flat baffles with no side 'wings'; it would seem that you would just be exaggerating the null at the side of speakers and increasing the 'phasey' effect. I wouldn't think you'd get much bass at all, but I could be wrong...

I've seen (but not heard) open baffle designs that utilize push-pull configurations, mounted on the same baffle, albeit it an offset baffle (Linkwitz Orions) and configurations where the bass drivers are mounted one behind the other on seperate baffles (Legacy). Supposedly, these designs have great bass.

It would seem an easy experiment though, that is, if we're talking about a boxless design.

An open baffle is always a dipole....

Hi,

The effect would be similar to placing a open baffle near a wall, no bass.

Go for two drivers a side in bipole configuration, add a supertweeter.

See P10's site for some ideas.
