Why. Are you experiencing a problem?Quote:

Hi Geoff,I think my speakers are a bit “boomy” in the bass department.They are revealing and not shrill or fatiguing but I feel there could be more weight to the bass.Following advice posted by amongst others,Paul...RFC...I’ve shortened the port tube which brought immediate improvements, and was hoping removing the original foam and replacing it with Silent Coat
would help further.I also intend to fit an internal brace.
If memory serves me right ,are your speakers non Hpd and therefore a different creature so to speak...

Yes, mine are later versions and do have an internal bracing shelf, but thats the main difference between cabinets. This may be a good mod for yours.
An easier mod that may help with bass boom, might be to put a decent depth of teased long fibre wool in the bottom of the cabinet, leaving a gap around the back of the port tube. Wool is an excellent damping material and not desperately expensive and it can of course be easily removed if need be.
I had the same feeling about the "boomyness" of my Chatsworth cabs, which are certainly more flimsy than the Cheviot.
A quick trick is to stack a heavy crate of LPs on top of it. It really helped deadening the thing.
Additionally you may try to tune the drivers by playing with the four screws at the front, finger tight works best.
