My good friend @GTmaker commented in a recent email exchange that changing the cab might possibly have more of an influence on the sound than changing the speaker. I fully understand that speakers and cabs are both giant "rabbit holes", but I thought I would risk that and start this thread. In an attempt to keep the variables somewhat minimized, we have with the same "decent" quality 10" speaker going into various open back cabs. However, cab materials and dimensions can vary. We will assume that the cab construction is reasonably solid (i.e., not rattling, etc). We will now reverse this (i.e., the above) and put various speakers into the same "decent" quality cab. We will assume that the speakers have similar specs and are in a similar price range (I know...that is not easy...you have to pretend a bit). I fully understand that obtaining speakers is typically much easier than obtaining empty cabs. Don't let that colour your comments. Let the games begin. I expect @Roryfan will be here soon. I know that he enjoys trying various speakers but I'm not sure how many cabs are involved.
