Excellent shallow mount subwoofer for the money! Well done NVX!

The following review is for SMW10D4, which is a part of the bundle you are viewing.

I purchased two of these and have only tried one so far. I have the 10" version in a nicely built prefab box (currently for test purposes) that specs right about 0.81 cuft sealed. I'm currently testing it in a preexisting system in a Honda S2000. Its being powered with a 500 watt NVX VAD series amplifier. I have to say that this subwoofer has impressed me more than I expected. The sound quality is quite good for this dollar amount. I am very happy to see that NVX chose to use a rubber surround as opposed to the foam on many of their other subs. I cannot speak to longevity or durability as I haven't had them long enough to comment on that. I'm planning to install them in the spare tire location in my 2022 Veloster N. At just 3.23" deep there will be plenty of space. I hope NVX continues along this line of design for their future of subwoofers. Thank you NVX! Well done!

The following review is for A202-10, which is a part of the bundle you are viewing.

this is an amazing sub box. It fit perfectly under my seat. I love the bed liner covering. It makes the box look so clean. and it won't scratch. I would recommend this to anyone.

The following review is for A202-10, which is a part of the bundle you are viewing.

nice looking box but the structural integrity of the box is weak - subs have a real hollow sound to them in this enclosure - i even went ahead and filled up each chamber with poly-fill, it help a LITTLE but still they dont sound right... you get bass.. but thats about it - nothing super quality about it. i put kicker comp RT's in it on a true 1200w kicker amp off factory radio
