i hear people talking about RC40's all the time. what i am curious
about is the diff between the twin and single box...how much
diff in performance is there? is the two box muxh quieter???

I have a twin box for ellmo. sounded good enough on the dyno.

I;d like to comment but will expect to shot down

Well didnt Vizard say that the second box produces no noticeble reduction in performance for the reduction in noise?

But then many people who run single box only RC40 must do so for a reason (cost ?). Doc don't you have a single box?

I run a single box RC40, now 10 years old and still going good.
Rumour has it a twin box is better and quieter. Buy it- you can always lose the front box later if you want more noise.
