U-Baffle

Pathfinder · 28th December 2006, 04:35 PM

Hi!

I have pair of DIY dipole speakers D-07(picture above), developed by Pekka Tuomela. Those speakers are usefull in range of 60-80 to 23000 Hz, and they wokrs very fine in my mind. I have used some active subwooffers with them but now I want to try wooffers which works as close same ways as my main speakers do.

So I think that U Baffle is the keyword when I'm solving my problems, there is only 2 "little" thinks that I can handle. How can I measure the
U baffle, and what kind of things I should take account when I'm choosing those wooffer-elements for u baffle?

Hope that somebody can help me, and sorry about my awful english!

Oh, and there is my D-07

Hi Pathfinder,

your english is much better than my Finnish

.
I like those speakers. They look very much like dipoles, not cardioids. So if you wanted woofers that work as close to the same way, then you might consider some dipoles like these H-baffles http://www.linkwitzlab.com/proto.htm#PW1
A pair, if you have the room, will provide plenty bass for music, but I would not recommend for Home Theater (movies).
If you indeed want a cardioid (or cardioid like behavior), then a U-baffle is what you need http://www.musicanddesign.com/u_frame.html

Good luck.

Thank you very much, AJinFLA!

The .doc is simple, but very usefull to me. I thought that U- and H-baffles works both like dipoles, and cause U-baffle can make the same job in smaler size thats why I choose the U-tyoe.

I just checked the PW1 and it seems to be something that I want. Is it better to make/buy own subwooferamp-module to the woofer than make passive x-over/EQ to fit that woofer with main speakers. I don't now why, but I don't want to but those passive components in my singnalway, like they have done in PW1/PXM1 project. What about real active x-over?
