...and isn't that what we all want?
It's loud. It's clean. It has mojo.
Brendan effectively was the guinnea-pig for these two designs which I had floating around and hadn't yet had time to build up. It is likely I will offer a 10" coax speaker down the road as a "fun-use" speaker. i.e. less audiophile critical, but robust, efficient, and very good sounding. The sub should sound great for music and handle plenty of power. It just squeaks by as an 8 Ohm load, and is tuned to ~30Hz. Without any EQ it should be +0/-3dB from ~30-100Hz and >95dB @ 1m/2.8V. It's entirely within excursion limits above 28Hz with a 500W sine wave (8 Ohm nominal) across the range. It doesn't hurt that the port has the cross sectional area of an 8" diameter port! If Brendan bridges the 1850HD into the subs, the pair of subs should just tickle the 130dB @ 1m mark, which is well into pro-audio capabilites, with much more low end than most.
