I have had a few of these in the past, their sound repro is superb and perfectly balanced.
I mistakenly over'powered 2 in a unit by hooking them in parallel at 50 watts, pop & kaput. Only 25 watts each thank you.
Mine are in separate boxes in a 2kw disco system, crossover around 3.5k.
Very, very loud, so please be careful, even when testing with a 1-1/2 volt battery, these are loud & will hurt your hearing.
The ultimate for big power sound systems and I've tried many.
I couldn't afford to order these in my local music shop, maybe a month wait, but thomann have plenty of them.
