Re: I can't hear my 1960a cabinet.
Man, I thought that moving from a combo to a half stack was forward progress. From reading your very well informed replies, it seems that I am dealing with a totally different animal now and a very temperemental one at that. I certainly went into this with both eyes closed and not expecting anything more than a perfect result.
It all makes sense to me now. Perhaps these cabinets work at their optimum when they are arranged in a wall like a stadium rock act has.
OK, I've just finished up in the garage and this is what I have done.
I picked up a sheet of 15mm MDF (same thickness as the Marshall back panel), measured it to exactly 3/4 the size of the original panel, cut it out, made the cut out for the jack plate, rewired the 4 speakers so that LEFT is now the top 2 and RIGHT is the bottom 2 and screwed it all back together.
I fired it up and everything works fine. Testing out the new configuration in a garage is not the ideal situation. The sound between the TOP speakers and the BOTTOM speakers is very different both in tone and in volume. The TOP speakers project the highs really well and I can't run the amp past 2.5 to get the same volume as I did with the original closed back config on 4.
The BOTTOM speakers are different again. Much more fatter sounding but I need to crank the amp up to 5 to get the same volume level but that's academic because the mix of frequencies are different so it's not a fair comparison.
Operating as a full quad, it is noticeably boomier in a good way. The sound does spread out more but it's hard to say just how much because it's solo in a garage. It is louder than compared to closed back form and I *think* I can hear alot of sound coming out the open back but that could be because of reflections.
The big and the only real test is going to be using it at a full band rehearsal. My theory is that using only the TOP speakers with the open back, will be like running a combo raised off the floor. I don't know for sure. Still need to experiment with but I think it has potential. Will let you know after tonight's rehearsal.
