£213 GBP each, soon stacks up, if 2x driver per mid cab, 4x mid cabs.

no, beause the synergy horns are a conical horn there is far less throat distortion because of the higher flare rate. with an exponential horn the air starts distorting because of adiabatic compression.

Ouch!

Last term I heard a VRX rig, it sounded a little "shrill" to say the very least! Wink

Like a lot of JBL stuff, very top heavy, but some people seem to like that. I did a gig a while ago where the group brought a couple of VRX 932LAP´s and asked me to wire them in as side fills! Talk about shrill. I suppose they'd never heard about in-ears.    LOL

These (cp380) can be found lurking in Mach 1x15 cabs. The MDF ones with the silly rear protruding handles that snap off. eBay bargains sometimes

Beyma actually have some 1.4" drivers, that according to response graphs, have better 12-18k, than the CP380.

Top end is very dependent on the horn used.
Wider the horn dispersion, better the top end. No throw dough.
CD horns also suffers at the very top end, but provide most even dispersion.
Tractrix horns offers best on axis top end, but not to the rest of dispersion pattern.
You need to stop looking at specification graphs, unless you plan on using the same horn measurements were made with.

There is much to gain, from using same horn, measurements made with..

There are few exceptions, like B&C ME60, which sounds immaculate with Beyma 2" drivers.
