[QUOTE="Electrodynamic, post: 3290505, member: 548723"] This is getting slightly off topic, but you can't get around Hoffman's law. Using a LOT more power still means your efficiency has gone down if you're allowing more room for the other two categories. Think of the law as a pie chart - if you increase one part, the other two get smaller. Increase two parts and the one part left over gets considerably smaller. On that note, if enclosure size is 50% of your pie (i.e., a small enclosure), efficiency and low frequency extension will suffer. Sure you can add more power to make up for the loss of efficiency but your low frequency extension is still suffering. Attempts at getting around this have been done many times - take a look at the Sunfire cube subs - super tiny enclosures, LOTS of power, a PR and more EQ boost than you've probably ever seen. The result is a tiny sub that slams but it's not the cleanest on the face of the planet because the driver is working SO hard to produce all that bass. With the BM's enclosure sizes ranging from 0.5 sealed to slightly over 1 cube sealed for optimum performance, they're a formidable driver for small-to-medium sized enclosures. [/QUOTE]
