First, some historical context... I live and record in a small terraced house with
neighbours on both sides. For the past 3 years or so, I've been doing all my guitar
recording by plugging my amp into an isolation cabinet (built by Paul Cornford). I've been
satisfied with the sounds I've been getting, using the Celestion Vintage 30 and either an
Oktava MK012 or an SM57.
However, it's now time to take things a little
I want to record my Fender Champ, but the design of my iso box doesn't
really allow for the addition of another speaker (the Champ is 4 ohm, whereas the existing
speaker is 8 ohm). I'm sure the box could be modified by a half-decent joiner, but I've
come to consider selling it and designing THE BEST COMPACT ISOLATION CABINET EVER!
So... I'd appreciate any advice or suggestions on perfecting my design, in terms
of soundproofing and acoustics-related internal dimensions.
criterion is that it has to be reasonably compact. The current box is 36" (L) x 24" (W) x
20" (H), and I wouldn't really want to go any bigger than that. It also has its single
speaker mounted on a plywood baffle half-way down the length of the box, although I'm not
sure why (perhaps to simulate the sound of an open-back cabinet?). I'd like to have a
baffle at each end, one for the 8" speaker, one for the 12" speaker, allowing plenty of
distance in between for experimenting with mic placement.
Then, what about the
soundproofing? The current box is constructed from 18mm MDF, lined with strips of the
standard grey foam you get from Studiospares (probably about 20mm). Would a
box-within-a-box be a better idea? Perhaps a layer of thin MDF or plywood within the layer
Enough of my waffle... all suggestions gratefully received!
