As i mentioned in an earlier post, I want to put a pair of 8-ohm Celestion Blues (15w ea.) in a Bluesbreaker reissue. The BB is wired with two 16-ohm speakers in parallel, for an 8-ohm load. The impedance selector on the amp has 4,8 and 16-ohm settings. Technically, I should be able to simply swap out the speakers, set the selector for 4 ohms and be fine. However, I've heard that it's better to use the highest impedance possible. So, in order to do that, I'd have to wire the speakers in series, for a 16-ohm load. Now, as the BB has a 1/4" speaker jack, I'm not sure how to do this. Can anyone enlighten me? (I know how to wire two speakers in series -- I'm just not sure how to do it into a 1/4 speaker cable). Thanks!
