Some extra information that wasn't on the website:
Confirmed that these do not have shorting rings.
They have Dual 2 Ohm Voice Coils.
Recommended XO is 80Hz or below.
Unlike the SQL 15s I am getting ready to play with, and which can handle GOBS more POWER than advertised...
The HT-18 v3 is 750w with 1500 peak. Nick said these are not going to hold up in the same manner as the SQLs and said the 750/1500 is a good figure. Pushing beyond could lead to thermal failure.
In all, these are absolute performance and value monsters. They will be capable of playing low and loud. Nick even said these could easily be driven from an NX3000 Amp.
Super tempting.
