What is the best HEAVY METAL speaker?

go over to youtube.com and type in JTR Growler duo subwoofer and triple 8
speaker. there is a lot of wind noise in the vid, but you'll get the idea. Make
sure you watch it till the end.

Best rock and roll speakers I ever heard were the Heil Air Motion Transformers (AMT1), two on each side.

Glenn and KK were racing across the heavens in my sound room last night. Lots of power and STATS work quite nicely.

For a larger room, any of the bigger Legacy speakers will work well (Focus SE and up). Though the Legacys have fairly high efficiency ratings, they like a lot of power. For a small to medium sized room, the Vapor Audio Arcus paired with a good sub would be very tough to beat. I own a pair of Arcus and they will play down to the mid 40's at any volume I can withstand in my room and not fall apart. The subwoofer will give that low frequency lock that metal music requires. Arcus have some of the best midbass of any speaker I've ever heard and will play it to extreme levels. These recommendations are based on if they fall within your budget, obviously.

Any of the old Polk Audio speakers that have the multiple 6.5 inch woofers and the passive bass radiator. They are the best bang for the buck and can handle all the power that you can throw at them. Just ask anyone that has ever owned them and they will agree that these speakers can rock.
