I have owned :radio shack mc 1000's, homemade,AR3a,s,marantz 12"3way's,infinity 12"3way's,kef coda's,spectrum 108a's,spica-tc-50,apogee caliper's(used),vandersteen 2ci's(used),energy c-2's,ar m1's,alon petete,proac 1sc,proac 2.5,alon 2's(used),dq-10's(used),ads10"2way's,vintage electrovoice,jenson,fisher,ar's,allison 2'slarge advent's,nht super zero's,boston acoustics a60's,phase reaserch's.I sold most of them.I still have the spica tc-50's(great for the money).I wanted the challenge of building some, after all of the experience I have now.I modifyed a pair of Design Acoustics ps/6a's(doped the 6.5" cone,shallow horn on.75"soft dome,6/db octive crossover to tweeter,added port,minimal damping material,removed dust cap from woofer. Sounds very fast,and detailed. bought some 12"pa horns,replaced innards with a paper tweeter,and 6/db octave crossover. Another pair of 16"horns w/ 4"paper cone woofer. The horns are mounted next to the monitors,and hooked up to a low cost amp/equalizer. The 1khz, and 2kz tames most of the horn colorations. A slight boost around 10khz adds life. You can laugh if you want,but with most recordings,detail and dynamics,coherency,and rapid transients are more involving than anything i have owned! even with low cost wire. I can turn volume up and down on the horns, to hear the difference. They really do add a stunning liveliness. The only price to pay, is an occasional recording,brings "some" notes "out" a bit much.
