Re: Upgrading Subs – New Driver or new Sub –What would you do?
Stuart,
The variables are the TS parameters of the drivers you would upgrade to, and port velocity concerns if the upgrade has higher Xmax.
Doubling Xmax of the driver has the potential to increase output by 6 dB (if the air is not blown out of the ports) but will require 6 dB more power.
Going to a tapped horn design can give 6 dB more output with the same power (and another 6 dB if a driver with double the excursion is used), but requires a larger box.
David Mcbean's free program, Hornresp, can help decide if another driver will work better than the ones you have in the box you own, if you have the TS parameters for the speakers in the box.
