very satisfied with my purchase

I'm very pleased with the overall quality, weight (lol) and look of my new xl 12. and did i mention the loudness! it has a very clean/ tight sound that i didnt expect, and in optimum box size, hits a good range of bass. But if u want more lows id go atleast half a cube bigger in box size. i think im a dc audio guy now! i wouldnt shy to say that its a bargain for a nearly competition level subwoofer, i could'nt imagine two of these things!

My Level 4's lasted me 8 years. Now its time for an upgrade. They were very helpful getting my subs upgraded and customer service was legit. THANK YOU SONIC FOR GIVING ME A DECADE OF BASS. DC AUDIO FTW.

DC Audio XL12 m4.1 D2

I would definitely recomend anything DC audio. And the XL is there best selling sub for a reason it’s sets in that sweat spot for an ultimate ground pounder yet can be used in huge competition setups if need be. And believe it or not they have decent sound quality. Is it warm as a dub 7? No but what little it lacks in sq it more then makes up for in spl it has truck loads of that. Throw 2 of these bad boys in your trunk on a DC 5k and watch stuff start falling off your car like it’s made of glass.
