For years I've used a 2-10 Jensen cab with an RD50 head. Cab loads to 4 ohms, but was only using one speaker out showing the amp an 8ohm tap. Other night I finally RTFM and put a blank plug in the external speaker out jack, and the amp reacted with deeper lows, much more punch and solid mids, clearer but less piercing highs, just a significantly better sounding amp over an already outstanding product. Guess the 'experts' saying a 100% ohm mismatch was fine were wrong... Question - I've been wanting to have a Bandmaster style cab built, with 3-10s. How could 3 8ohm 10s be wired using both speaker outs to present the amp head a total 4 ohm load? Thanks | ||

No combination or three 8's is going to gibe you 4 ohms. Series, all three, 24 ohms. Series one with two 8's in parallel gives you 12ohms. All three in parallel gives you 2.66. Two in series(16) and then in parallel with the last gives you 5.33. Nothing will give you 4. | ||

That's what I was thinking... Gotta put the pencil to this, to find a combination to give up either 4 or 8 ohms, though. I recently played a 3-10 set up (1st time in a very long time) and realized I gotta, just gotta have this,., | ||

5.33 ohms won't hurt anything if used on the 4 setting. The only way you will get 4 ohms out of three speakers is if they are 12 ohm speakers. THOSE would be hard to find(like they don't exist, I don't think, unless you had them MADE) Mike |
