I am "slightly" over driving them. Currently I am using a Phoenix Gold MS 2125 bridged to each sub. Before that, there was a MS 2250 bridged to each one. The MS 2250 makes ~1400 watts @ 1.5 Ohms. We are down to a more reasonable 700-800 watts per channel...What are you powering them with?
Glad you liked it, but the 13TW5 only requires about 0.8 cu.ft. which is a heck of a lot less than most 12-inch subs require for good, smooth performance.I listened to a JL this weekend. I was impressed it did 99% of what a W6 will do.IMO
They are pricey though and the air space requirements are about the same as a regular sub.
