I want to make some high efficiency dipole surround speakers for my HT.

The front and rear speakers for multi channel music are all Pi7 cornerhorns, and the center speaker is a Pi4 with added midhorn.

But I would like to try a 7.1 setup with dipole speakers for movies.

To keep up with the dynamic and high efficiency of the Pi´s, I think I need some horn tweeters, and that´s why I thought of a Klipsch RS-7 clone.

I will use an Eminence Beta 8A for the bass/mid and need a horn with about 90x60 coverage for the highs.

The RCF H100 horn looks nice and fits the bill, but what driver should I use, or should I rather go with a complete horn tweeter like the Beyma CP09 ?

I would like to cross over at 2-2,5khz and have looked at the new Eminence ASD1001 driver, does anybody know how that sounds ?

If anybody has any other suggestions please speak up.

I wouldn't configure the tweeters as a dipole though, because to do that, they would need to be wired out of phase. The idea is to reduce side radiation by cancellation. A dipole radiation pattern forms two lobes, in front and in back. If the horns in an RS-7 were configured as dipoles, you would have no treble out in front of the speaker, only out to the sides in narrow lobes directly on-axis in front of each tweeter.

I'd wire the tweeters in phase, and attenuate them to match the midwoofer.

I think I will change the design a bit though.

After looking at the Klipsch RS-62, I think it makes more sense to have a complete set of drivers on each side.

I will use two Monacor SP-6/150PA mouted in a 14-16liter bass reflex triangle shaped cabinet, that should give me a F3 of about 75hz.
For the compression drivers I think I´ll go with the new BMS 4524, it can be used down to 1900hz and is still very cheap.
The horns are not yet completely decided, but something nearly square with a 90x60 pattern is fine.

After thinking it over again, the dipole arrangement makes NO sense at all when using horn. I´ll just wire them as you suggested in a bipole arrangenment.
