I have a pair of B&O CX50 speakers. The woofer has been replaced with one of these The speakers have a great mid/hi, but the bass is very, very dull. Now I was wondering if adding bass reflex port would do it any good, and if so, what Fb to tune for to get a feel of some better lows?
The internal size of the cabinet is around 3,4 Liters. I was thinking about a 2,5cm bass port. I did some calculations using this spread sheet but I don't know if I'm off?
My experience with acoustics is very limited so any advice is highly appreciated before I start drilling holes in my old vintage speakers.
