The SCC300 sealed in about 3.5 cubic feet has an F3 of about 36hz F10 of about 20hz. This balanced nicely in my room with no drone. However, it might NOT make folks happy that want the droning "boom boom" sound in their room. It also appeared that Al Garay found a disproportionate amount of boom boom in his room. The SCC300's relative high sensitivity at 8 ohms nominal (90db) is directly proportional to the size of cabient required. For every 3db of sensitivity drop, the cabinet size can be halved. For the "same" 8 ohm woofer at 87db @ 2.83 volts the cabinet could be 1.5 to 2 cubic feet.
For the "same" 4 ohm woofer at 87db @ 2.83 volts the cabient size would be .75 to 1 cubic feet. This is because there is a 3db simple mathematical gain of the 4 ohm woofer. The effective current (and voice coil thermal compression) of a 8 ohm 84db @ 2.83 volt woofer is equivalent to the voice coil thermal compression of a 4 ohm 87db @ 2.83 volt woofer. Both of these woofers will flow the same amount of current.
There IS a reason high sensitivity drivers are better - less thermal compression. The cost is a significantly larger cabinet given the same bass extension.
This explanation is probably more than what you expected. I suppose it's another way of conveying the SCC300 is very clean, but was designed more for clean bass than "boom boom". I think the SCC300 is a killer woofer, and agree with Randog in this vein. I think a single is sufficient, but 2 in either front corner will provide more a more symmetrical bass soundstage.
My 2c.
