You can go to Ohm Acoustics site and check out the Walsh Driver technology. The Walsh driver produces all frequecies up to 10K or 14k then it is switched over to a 3/4" super tweeter. This high crossover frequecy keeps any switching in the harmonic frequencies. The Walsh Driver is a fully coherent line source driver. I own them and they are astounding. Their mids are like electrostats.
Crossover-less Speakers
I'd like to hear from those of you who transitioned to crossover-less speakers. I have a pair of Thiel CS 2 2s. I like 'em but I'm curious about the full-range crossover-less speaker types. I'd like to know what speaker you have and what speaker you traded up from. Are you getting the full range from your spkrs? Are you experiencing any peaks and valleys in the frequency response? Are you happy with the lows or are you augmenting with a powered sub? Thanks.
