Why not horns?

Mapman - Scan back up this very page about 10 entries and you will see a pretty complete recipe for my speakers that I submitted on July 20. If I wasn't clear or didn't provide enough info, feel free to ask me questions.

macro,

I see it.

Its not clear to me what the dbx does and whether a separate crossover of some sort is needed?

Thanks.

Here is the newer PA+ version. It does all the same things that mine does. I use it as a crossover, time delay and EQ.

With this device you can shape your sound any way that you want.

MJ,

So what is handled in your configuration by the JBLs versus the custom horn loaded drivers?

Are teh JBLs biampable or is the complete full range speaker in play but fed only a certain frequency range by the dbx acting as a crossover?

The JBL has a passive crossover built into the cabinet but there are connections on the back for separate driver hook up. At first I used the JBL XO and just disconnected the mid-range horn in the JBL and connected my AH300 horn instead.

Then when I got the dbx, I ran out of my preamp to the inputs of the dbx and then on to an amplifier that drives my horns and another amp that drives my woofers. Currently I have replaced the JBL woofers with a pair of RCF L15P530 woofers. The only thing from the JBLs that I still use is the box.

My crossover frequency between my woofers and my horns is 300 Hz. I use a 24 db/octave LR filter in both directions, one half meter of time delay, and a small amount of shaping. I'm sure I don't have it optimized but I'm quite happy with the sound overall. Does this explanation make sense?
