The new combined lower impedance just means more current will flow out of the amp so if you use the same settings, then there won't be any "easing" on the existing speaker - however you might find that you now have the volume turned down a little so it will help in that respect.
The current will shared between the 2 cabs and normally one would use the same impedance cabs so that they get an equal shared, in this case the ampeg will get approx 57% and the ashdown 43% of the current - not a huge difference.
The sensitivity of the speakers will be more significant in dictating which cab appears louder, but as I [i]assume [/i]the ashdown speakers are more sensitive I guess you find them pretty evenly matched.
Sounds like a nice addition to the original amp :-)[/quote]
yeah, they are pretty evenly matched! I highly recommend the ashdown/ampeg sound, you get the best from both companies! Thanks for the feedback everyone, appreciate it!
