Ok, so I'm looking for something with a more "tight" "punchy" sound than the L7 I currently have. I think the SI BM would suite my needs. But, I'm confused on wether the RMS is 500 watts or 600. In the description it states "600watts power handling" and in the chart it says RMS is 500 watts. Either way, I have 750 watts to throw at it. Can the BM handle it? Would the BM be considered SQL or atleast have better SQ than the l7? I'm done scouring the net for woofers, I'm selling the L7 and getting a BM if it will infact handle 750watts. Unless someone has a better SQL driver in mind that will handle 750 at 2ohm and be in the $300 price range...?
