high end jbl or horns or emerald physics c1

I had a pair of JBL L-200 speakers sitting around here for a few years when I discovered Acoustic Horn Company. In speaking with the owner, Bill Woods, I became convinced that all my L-200 needed was a better horn. This proved to be true.
If you go to:

you can see my project which, I suspect is exactly what you are looking for.
They will play very loud with no breakup and the clearest, most natural, undistorted reproduction I have ever owned.

I bypassed the horn and crossover in the JBLs, mounted the ah300 on top and biamped through a dbx Drive Rack PA. It was a very simple mod.

Expand your listening tastes and buy speakers that can play all types of music. =8^)

I first thought my JBLs were king, no other speakers in the world can beat it. Oh boy, how much I was wrong.

Oldrockstar knows what he wants and explained what he wants and asked for help in getting realistic (dynamic) sound reproduction. He has probably been in a band and knows the feel of how it really sounds. FWIW - Dr Floyd Toole believes musicians and sound engineers listen differently from ordinary folks. He believes that untrained folks prefer more ambience and reverberation and coloration whilst musicians have a heightened sense to coloration and tend to prefer a clean transparent or "raw" or "thin" sound. Horses for courses...

i recommend a pair of jbl 4430 or jbl 4435 studio monitors. you will not go wrong regardless of the type of music you want to listen to. if you dont want a 2 way spekaer, how about a pair of 4355 studio monitors which are 4 way? excellent detail regardless of your taste in music. flush mounting the monitors reduces defraction distortion, this is one reason it is done in studios and this is the way i have all my monitors set up. also lets not forget, the first powered/active speaker was the jbl hartsfields (1960) with tube amplification. always compare speakers to live events not to other speakers. if you try that you will take the politics out of buying. if you would like any other info regarding these speakers dont hesitate to email me and perhaps i can help.

I second Ditusa suggestions.

Look into Tannoy before you decide. I have owned most all vintage Klipsch am I altec JBL collector as well as other vintage loudspeakers. And a Tannoy monitors is a good step up in performance over the vintage kit. Some guys have near give away prices on there tannoy studio monitors.
