The E series woofer was designed to eliminate our typical frustrations with entry level woofers : low thermal capactiy, limited mechanical capacity and durability, and low motor force. The E series woofer utilize a high quality 2" copper voice coil wound on black aluminum anodized voice coil former. The coil is then mated to a large diameter high quality nomex spider on all three sizes fully equipped with round tied down tinsel lead wires to ensure the utmost levels of durability.
Of course this is Sundown Audio so we didn't stop there -- not even with our least expensive woofer! The E line is equipped with our proprietary custom tooled triple joint support ring (this ring was originally developed for the SA and Z v.3 lines) to prevent glue joint failure even under the most extreme circumstances. The thermal capacity of the coil is also further enchanced by a chamfered solid pole piece and direct voice coil gap ventilation -- features almost never found on an entry level woofer. As with all Sundown Audio woofers the E line features a large diamter magnet slug at a full 6.65" -- even our least expensive woofer is already making waves in the SPL lanes.

I've been running four of these subs for about 6 months. My enclosure is 5.5 cubes gross, 3 cubes net with 50 sq inches of port tuned to 35 hz. Each sub is getting roughly 400-500 watts rms at full tilt and handles it no problem. After a thirty minute commute at full tilt, the subs are slightly warm to the touch. I wouldn't hesitate doubling rms but it's really not needed. I'm very impressed with the build quality and the tonal accuracy of these subwoofers. Thank you Sundown for a great product and thank you SSA for a pleasant transaction!!
