After owning a bastanis setup for a few years I fancied a change so earlier this year I invested in some GPA 390-16 midband Compression Drivers. For HF I have some RAAL lazy ribbons. Bass is Open Baffle 2 x 15" Hawthorne Augies. I have just got the system running.
At the moment FR duties are divid out
Augie bass 20Hz -380Hz -Active via a Behringer DCX2496
GPA Midband - 380Hz - 7Khz
Lazy Ribbon Treble 7KHz - 25Khz
Apart from a bit of volume levelling and the odd crossover tweek the bass and treble of my new arrangement are reasonably well sorted. But the midband is all all a bit naked and ragged sounding, decent enough and showing real potential but of course its meant to have a horn on the front . In terms of efficient speaker systems I have past experience at home with Bastanis, Avantegarde, KHorn and Hedlunds and this (I hope) will stand me in good stead.
I have read anecdotally that its best to use the midband driver as low as possible so initially I am looking at some very large midband horns. I do have concerns that my 16 x 12 room wont be large enough but I wont really know until I try.
I am currently in progress of sourcing these and hope to have a few sets to compare in the next week or two.
