Once you get past that the issue of LF cutoff of the horn is involved.
If you are looking to save weight, and have interchangeability, a pair of 2450J's would be the best choice. They also have a 4" voice coil ( rated at 100+watts ) and the driver is a bolt-on replacement that weighs only 10.5 lbs.
I have a pair and might consider trades...PM if interested.
