I picked up an Acoustic B100 an decided to take out the head. My Trace Elliot will slide right in with a bit of finesse (read hammers, crow bars, gobs of grease) Next I'm switching the internal speaker to a 250 watt celetion 8 ohm and changing the speaker output to b parrellel to run a second 8 ohm cab for larger places. The B100 cab has no ports and its a bit smaller than my 15" Trace Elliot which is also sporting a 15" Celestion. Any idea about the smaller B100 cab? Should I port it, leave it closed or?
