Small dipole speaker

esuko · 21st March 2007, 04:37 PM

Hello to everyone!

Spring is coming, so have to start thinking about new projects

I have been reading Linkwitz's great pages about OB-speakers. Not the easiest reading material, quite technical.
That brings me to my question i would like to have confirmation.

1. 40cm deep H-baffles point where the dipole 6dB/oct rollof starts?

2. 40cm wide baffles point where the dipole 6dB/oct rollof starts?

3. I can add 6dB gain from the ground in H-baffle situation?

4. Moving the dipole speaker from the rear wall i can get some more boost in the bass region?

I was wondering if i could build a realy small Orion like speaker.
27 TBFC/G for tweeter
L18 for mids
XLS12 for bass

Would a speaker with these drivers in a dipole configuration even compare to a small 2-way speaker?

For a US$ 25/year fee you could get MJKs loudspeaker Mathcad worksheets which would answer all your questions quite perfectly.
