The forward-firing full range CR125S drivers produce the full frequency spectrum without the treble peaks and other artifacts often heard with Fostex and Lowther drivers, along with surprisingly deep bass for a 4.5" driver. The drivers are only 86dB sensitivity, and the front and rear drivers are wired in parallel resulting in a four ohm load, so they are not intended for use with low powered tube SET amplfiers. The 40W/ch Monarchy class A zero feedback solid state amp I'm using to break them appears to be a good match.
