I am going to retire my flat bass traps and construct 12 x 2m high tube traps. similar to ASC's
Im using fibreglass pipe cladding , 5cm thick and with an ID of 30cm and the same with an id of 27cm. comes in 1m length

1/2 the tube will be faced with reflective material so the tube can be used as either an absorber of hf or a diffuser/reflector .. whilst still acting perfectly as a bass absorber ...all you have to do is rotate the tube to change between absorption or reflection.
They will be clad in a suitable thin fabric to compliment my room and have end caps to "seal" the tube and they can be stacked

The 30cm id tubes are from either insulpro or St grobain.. they cost around R400 and the 27cm id is around R300 a tube
I am making the end caps out of 5mm black acrylic .
It should cost me around R550 for the 30cm and about R450 for the 27cm version
I aim to do 12 x 27cm x 1m and 12 x 30cm x 1m
Total cost will be around R12000....
The actual outside diameters of the tubes is 40cm and 37cm (5cm wall thickness)

An ASC tube trap  is around $5-700 a pop for a 3 ft length ... approx 10x the price of my DIY.
