Earthquake Sound SWS-6, 5x 6.5-Inch Shallow Woofer System Subwoofers, 4-Ohm (Pair)

Incredible sound and a super smooth bass line Coming from a 6.9 subwoofer. Very impressive Thanks

Interesting speaker. Looks good and follows similar lines as many other shallow mount speakers. I mounted mine in a 3L sealed enclosure which was made of 25mm MDF (birch was not needed for a box this small) and it was lined with two different types of material Foam behind the underside and poly-fill around the sides. Had two, they were wired in parallel (2ohms total) and fed from an amp putting out around 400wrms with the gains set at around 60%. High passed at 50Hz and low passed at 100Hz both on a -12dB slope and then the box was placed upside down on rubber door stops so as the bass plays down to the floor.. this hides any potential distortion and hides the localisation of the bass. RESULT: very good. does 100% of what I wanted and expected, a nice clean front bass sounds as the speakers are under the front seats. I am actually impressed, they are well made, look the part and for a 6.5in speaker do a good job.

Bought 2 pairs and each pair had one with a defective voice coil which rubbed internally creating an undesirable rattling sound. One of them even had a dent in the aluminium frame. On the upside, if you're lucky enough to get 2 good ones, they'll sound amazing!

Installed on BMW E90 base audio system, great bass, so happy!

Strong with heavy bass subwoofer.

One of the speakers did not work, it would rattle, the other one sounded ok but the box was made for the two subs,. I would give an update once i return them and get my reinbursement

These are good woofer replacements for doors. Be sure to get low pass crossovers. They take a week to break in. First day not much bass. Second week these kick in. Lots of strong bass. Also, be sure they are sealed around surface mounting area.
