Default DVC subwoofers

How would wiring a SVC subwoofer in any way effect it's performance? I am refering to the Mach 5 10" sub which is DVC with 4ohm+4ohm voice coils yet the amp I am planning the use with it puts out 300 watts rms @ 4 ohm and only 170 @8 ohm is there any way to get around that by just using one of the voice coils?

You can drive one coil. Power handling (thermal) will suffer, it will NOT be cut in half though as some may try and tell you. You will have a change in the drivers electrical Q also, but you can use/exploit this by either shorting or putting a variable resistance on the un-driven coil. You could have a driver with a variable Q.

Or just run the coils in series and see how you like it....

I wouldn't do that. You give up half of the BL that way. The only situation I can think of where that would be a good idea is perhaps with dipole use where the higher Qts would be desirable, and where little power handling is required.

Instead, I suggest either accept the limited power, or use a different amp, such as a 2 channel power amp that can be bridged into an 8 ohm load. The behringer A500 will put out 500w bridged mono into 8 ohms, more than you need.
