Go on then Andy, please talk us through it

[NealG]

There's some glimpses of the Quasars in this Video

[Clive]

So what's all this fuss about valves, the sound quality's rubbish!

Interesting to view it again. I also noted a glimpse of Andrew's bad back

[James D]

I have a dimensioned drawing for the Quasars. I'll send then through to Andy. No need to make it hard for him

[Andrew]

Oh, this I gotta see! Go for it...

Thanks James, drawings and pics recieved and understood. Looks practical enough to make from my perspex(tive). However minimum thickness for dimensional stability would be a minimum of 8mm thk acrylic (10mm would be
ideal as long as the vibration absorbtion through the material did not distort any of the audio frequencies) I suppose its a case of trial and error for the discerning ear but what would help is not to oven form the acrylic but to line
bend, i think the best effect is to maintain the straight lines between the angles to create as flat a surface as possible to mount the speaker driver units. The side panels can be bonded with clear UV resin and the edges polished to finish the enclosure. Incidentally the specific gravity of acrylic is 1.19 if you wish to calculate weight and any other contigious factors related to sound reproduction.
Andy.

Well done Andy!
