Polk DXi1240DVC

Polk 12" works great paired with Belva ported box and 1500 watt amp in my BMW, but sounds great and is all is expected.

DXi1240DVC

This polk came as a package with the BBX112 BK enclosure and did a really good job in my wife's BMW, I would recommend for a stater who wants a little extra bump for the daily commute.

Holy cow!!

Bought this as a replacement for another brand and all I can say is wow!! Sharp crisp bass!! Definitely would buy again!!

By Emilio on December 14, 2016


Bass on 40 bucks

For price the polk is great must have sealed 1 cubic ft box. Not for small enclosure this bass on budget is great.only downside the speaker terminals are not push terminals but what u expect for 40 bucks.

Works Just Fine

So far so good. I have it hooked to a Kenwood 600 watt amp and it sounds great.

By Keith Stone on October 17, 2016


For the money can't be beat.

Nice,crisp sound for those that want bass but no trunk rattle

By kinsley on October 9, 2016 Checkmark Icon Verified purchase


DXi is legit

to be honest I never had heard of DXi mostly I knew about the DB series but this 12" sub right here really provides a lot of boom, if anything I think they underrate their subs unlike some of the low end brands out there, I'd consider this a competitor to Rocford and Kicker at the fraction of the price. I put this in a sealed box, wired to a 2000 watt belva amp Sonic recommended and the boom I get is 10/10

Quality Sound on a budget

Money is tight and I needed a budget subwoofer that could satisfy my needs. I did not know what to expect when I purchased this sub but was blown away when the first time I hooked it up. I am running it on a NVX MVPA1 and the bass thumps in my trunk. Need to purchase some sound dampener because of how hard this thing hits.
