Not easy to blend anything with one of the most efficient horns out there. You just have to listen to it full range to even imagine trying to blend the bass…the 15a sccops down to around 80/100hz in a magical musical way. Forget any modern “lets pump air” home freindly solutions. Any bass to match the 15a will be in the “big boy” category!
