This is a killer bass speaker with high sensitivity (100 dB @ 1w) and serious low end presence. Unfortunately, it did not work out in my W bin Kustom cabinet so it's up for sale. B-18 guys, this speaker would be an amazing choice to get the most out of your amp. The same goes for the rest of you. 4 ohms, 300 w RMS. 30 Hz - 2 kHz. One of the spring loaded wire clips thumb tab was mostly snapped off but is still totally functional. $125 + shipping OBO OR $160 for this AND the Mesa Road Ready 118! You can see a little bit of silicone seal left on the back of the mounting ring on the bottom of this picture.
