Lad,
This thread is stale, but I thought I'd chime in as an M4 Turbo S owner with now about 200 hours on them and they simply wonderful. I hooked up my REL T-7 sub and it sure fills out that the lower octave in a way that makes the sound presentation come alive. They are very easy to drive with a 7 wpc tube amp, but also sound wonderful with a CJ solid-state amp. I could't be happier wit the sound I am hearing. Cheers, Mark
