I have a couple or three of questions on speaker design:
I have a pair of well gigged speakers bought second hand and the cabinets
are very tatty. These existing cabs are of chipboard. Would it be a good
idea to use MDF instead to make new cabs?
I have heard of cabs being carpeted, does this mean that the interior is
lined with carpet? if so what is the best to use?
The 15" base speaker seems to be compartmentalised, sparated from the rest,
tthere are 2x12" and 2xsmall rectangular horn like speakers, I'm not sure
yet if these are separated. Is it better to have them separated from each
other to avoid interference?
TIA
regards

mobile speakers need to be made of plywood for durability and weight.
Chipboard particleboard MDF will all fall apart if knocked,
carpet is generaly used on the outside of PA speakers for knock protection.
separate compartments for the woofer, the mid and tweeter prob can live
together ok.
line the enclosures (cabinets with bitumin or similar damping material if
not using them mobile,
otherwise use 2" audio foam.and stuff them with fibreglass as well, this
lowers the speed of sound in the cabinets and makes them seem to have more
volume.

I bond roof felt with instant nails in my speakers, all the internal
surfaces.

MDF works well for cabinets.

So does 20 ply birch plywood, but it is expensive.

Carpet covered means Ozite on the exterior.

the 12's and the horns can be in the same compartment.

the horns are not affected by pressurization from the 12's.

woundnt MDF be a bit fragile for mobile use?
and heavy too.

MDF is widely used in mobile applications, but if you want a solid upgrade
see Richard's comments about 20 ply birch plywood.
