I installed a pair of these in a MOJO 2x12 British style cab (offset, closed back). The cabinet is used with a Marshall SV20H or a Friedman DS40.
During the first week of playing I could not develop any of the enthusiasm for the BV-25M that other reviewers had reported before me. Actually, I found them quite boring. Their midrange sounded annoying, and overall they lacked of the harmonic complexity that I expect from Celestion type speakers when overdriven. I did not even feel tempted to play them for a few more days. Disappointed, but also knowing that most speakers need time to break in I fired them up again and kept going for a few more days.
After an accumulated 20 hrs. of playing the situation changed quite noticeably. The speakers now deliver a nicely balanced and sweet tone across the frequency spectrum, and they produce a complex and pleasant distortion when overdriven.
They are a fantastic match for the SV20H and my style of playing! Thank you, Mojotone!

These British speakers sound absolutely fantastic paired with my 45 watt British combo. Without a doubt, it’s the best sounding amp I’ve ever owned!!
