Sundown Audio E-15 D2 v.3 15" 500W RMS Dual 2-Ohm E Series Subwoofer
The third version of our acclaimed E series is all new for 2016. Since we introduced the first E series in 2012 we have sought to push the limits of entry-level woofers forward. Typical entry level woofers are highly limited in terms of linear excursion, mechanical ruggedness, and thermal performance – all of these bars have been raised once again for our third generation E series.
The new stamped steel frame is also significantly stronger than previous generation E series woofers & features an enhanced “Sundown style” high pressure vented spider landing. Working in conjunction with a motor ventilation system based on our SA series & the new, larger voice coil the third generation E series possesses thermal capacity unheard of in this class of subwoofer.
Bottom-line; if you are looking for a great subwoofer option and do not want to break the bank the Sundown E-Series woofers are for you & these are the best E series made to date. They are ideal for anyone from beginners to seasoned professionals seeking industry leading performance at a value price point.
