[QUOTE="SUBBASS, post: 8393858, member: 666179"] Comments from my Bob Carver friend: "Looking at the specs, the eight ohm looks more appealing. Higher bl, lower fs, qts is a touch lower . The vas is showing this is made for a small box because there is a lot of stiffness in the suspension so it takes a high power amp to get things moving." "Once moving, it should go well. Sealed box, small passive radiator box, to medium ported." "Lots and lots of mechanical resistance leads to the driver needing more power to produce the desired output. Go to sunfire.comand read the marylin monroe white paper. In acoustic watts output, it does not require a huge box for the same output level once the math is worked out. I tell you, bob carver was on to this long before the rest simply took his observations and ran with them before his patent on high bl woofers in small boxes was the normal. All bob no matter what the haters tell you." "Once out, bob could not convince his speaker was unique, so he lost the patent and the world got some bad *** woofers at the time from kicker, rockford, and most noted for big bass in a small sealed box, jl audio. The w7 was the pinnacle of this work." "Think of this. To get more ohms, more wire. More wire, more mass. More mass , lower resonance. Also more coiled wire. Stronger magnetic field at the voice coil gap." "Lower resonance from more weight" Any thoughts after reading the quotes? [/QUOTE]
