SPL brand subwoofers
#3
They are both pretty much a Chinese type SPL sub. Very basic, handle the power fine. Not very efficent. Depends on cost I guess. They do the job fine. For a few bucks more you can get into an American Made SPL sub which normally a recone can be purchased just in case of failure. And some of our fine members here may have some slighty used SPL subs for a fraction of the cost. How much are they from where you are looking at and how much power do you have and voice coil configuration requirements.
