Hi.
I need help.
The big question is: How to gain extra power without having phase problems.
The ideal answer to this is simple: Invent a driver that is capable of playing all audible frequencies at 150 dB with at sensitivity of 120 dB and 2 pi coverage at all frequencies. However, Ronnie Rackham has so far failed to invent such a driver (he did try though!)
The next answer (and thats where you guys come in) - is more drivers, each taking care of a specific frequency-area.
Now - if I want to use more drivers for one specifik frequency area, then troubles are at my feet!
In particular I am having troubles with the treble horns.
Setup:
18" bass bins (Turbosound design)
12" ATC PA75-314 BLCR drivers, 4 pr. side, in a standard reflex cabinet. 2 units pr. cabinet.
1" Beyma CP350/Ti with a horn in front. Currently with a 90 x 40 degrees horn. One driver and horn pr. cabinet, 2 cabinets pr. side.
I am thinking of using a 60 x 40 horn and then put the 2 speakers at an angle of 30 degrees, and by this way try to avoid that they mix up and therefore avoid phase problems. However, i would like more power in this area! How to gain this?
2 drivers pr. horn with a V-piece?
Another solution is to use a Beyma 6MI80 mid-high speaker, that has a phaseplug, and is capable of playing quite loud up to about 4,5 kHz... However, how would I then avoid phase problems, when I have 2 drivers side by side? (Vertical alignment is not an option due to transportation of the PA-system)
Looking forward to hear from you wise men! Please Help!
Cheers, Hans-Henning, Denmark
PS: Im getting frustrated with these phaseproblems. Currently the sound changes quite remarkebly as one move around on the dance floor.
Any good suggestions?

Hi there
Of course, an ideal speaker will have an efficiency far above 100% - it will as a matter of fact be able to generate more energy than has been put into it, and thereby be able to provide it self with energy needed, plus, of course, supply the coffe-machine at the same time!!!
