Before my M80s I had a pair of Def Tech Pro tower 400s. They each had a 125 watt amp and was rated down to some where around 19HZ. There was no way in heck these speakers went that low. Mind ya I didn't do any frequency sweeps but you can tell when a speaker is truly full range. IMO they were nice but there is a lot of hype behind the brand.
I also had trouble with both amps on the subs TWICE. They did stand behind them but sending them back was on my dime. Even after that the amps would kick on every so often by themselves with nothing being fed to them. Hell I'd be just sitting here and then THUMP, the damn things would have turned on.
I sold them; bought my Axioms and never looked back. I'd bet ya the M80s reach lower then those so called subs in the Def Techs.
Oh and btw I had to send back the speakers and not just the amps.......$$$$$$.
