well if its a common chamber enclosure, then no sir, 6 cubes is not what is recommended. a single 15 at 3ft^3, i can go with that. but in common chamber enclosures, a single 6ft^3 volume doesnt have the same response, per woofer, as 2 single 3ft^3 volumes. you lose alot of back pressure on the subs when you make that assumption. if your running very low power though, this can help out a little by making the enclosure more efficient. this is where most people go wrong with common chamber enclosures. this is directly relative to your mechanical power handling. Hugh G - Wondering how you calculate proper air space for a common chamber enclosure? Is this effect true of all box designs (sealed, ported, bandpass)? Seems like it would be, just something I've never considered before. Thanks for the input on this. HI-PO - Good start to the build. I'll be following along to see where it takes you.............
