WOW... subwoofers just keep GETTING BIGGER!!! This massive 21 inch sub from B2 Audio is a real head turner. It's no stranger to the dance floor either because sub gets DOWN! Stay tuned for lots more on this woofer as we test the wattage from our amp with a multimeter and a clamp meter. Don't forget to leave a comment telling us what type of box we should build for this! :)

I remember back in 01 when i got my first mtx rfl, it came in a osb wood box with an extra cone in it and i had an idea to build a ported box and test it. Instead of putting it in my car I plugged it into the 120 volt /60 hertz outlet in my shop ! The cops showed up 30 minutes later cause the neighbors complained the bass was so loud it shook the decorations off the walls of their apartments 75 feet away! We all had a laugh and i got to meet my neighbors in a odd way! Keep up the amazing work my friend!

It's not a nice sub and the guy behind B2 is an ass.. Trust me, he lives less than 10 miles from me, and from visiting B2 a few times, it's clear that he knows way too little to be manufacturing properly engineered speakers.

LOL do you realize the box would take up nearly half the space in your theater room? And it would produce MASSIVE bass. Imagine watching Transformers or some action movie like that and there's a huge explosion. That would blow your brains out of your head. You'd be like the Maxell guy sitting in the chair having your hair blown back by the bass

You should without a doubt make this part of the home theater tower setup. You need to make a ported box with a built in shelf on the front that will hold all of your receivers and amps and such, and the box itself will become a big ass TV stand. Down fire that bad boy with a side slot port and you will have a KILLER home setup!!!!
