Anybody listen to the new Boston SPG555 subs. WOW These things are awesome!!! My friend got 3 of them in a 3 cubic ft sealed common box wired to 1 ohm being pushed by a Hifonics Colossus II. These sound sooooo good. Tight, hard hitting and go deeeep. He used to run 3 mmats subs, let me tell you these thing are way better, the sound quality is night and day. Im selling my L7 kicker and buying one of these. You need to check these things out. You wont be dissapointed!!!
