Used immediately with 12 amp 2X600W 8ohms and a compressor, rsultat: a membrane tear and a coil melted too strong in length and held her ....

I now use and hk jbl audio, nothing to do, but hey, considering the price, nothing to say (2 speakers + amp destocking 300)
you just have to not push the limit

the sound is loud in the treble, I also unplug two tweeters, a was much better

Speakon not just a jack 6.5
box strong enough, Gill forward, not the foam indoor, two winds faade

with the exprience I do not Rasht, but without the money to buy a good product better quality of
