JBL 4425: oiling the veneer, and bass boom
I recently obtained a pair of 4425 Studio Monitors from the late 80's. Now that the woofers have been re-foamed, a couple of questions:
The cabinets are in great shape, but appear dried out. Should I use linseed or tung oil on the veneer, or what?
No matter where I put them in a large, vaulted listening room, no matter how high off the floor, there is a strong bass underline. A giant, one-note boom. Is this normal for a 4425? Could the refoaming or age of the speakers cause this?
Otherwise they're great home theatre speakers. Thanks.

Yeah, you might want to measure the tuning frequency of those enclosures and make sure they are 34 Hz or lower. What is the port again? 2.5" diameter port x 6" duct? You might want to measure the free air resonance of those 2214H's as well.
