Perspex Quasar - Page 2

That's half-inch acrylic, correct? What did it cost? I can't find half-inch anywhere cheap, but then again I can't get the 1/8 inch anywhere online for under $40 for the amount that Home Depot charges $5 for.
It shouldn't be too hard to make it yourself w/ a heat gun and a good work table/forms.

I'm metric here in Italy so it's 15mm Plexiglass. It was very expensive. The sheet was metric 8ft by 4ft and cost 560 euros... But it was worth it 'cos my wife loves them and she would never have accepted wooden speakers this big.

I have received a couple of posts from people informing me that the picture links do not work. My apologises - my son erased them whilst updating some of his stuff....

I was one of the people who couldn't see the pictures but now I have, I am also impressed with the quality of finish.

When I designed my open baffles, I did have some reservations about using perspex or other plastics. Apart from the possibility of colouring through aging/exposure to ultra-violet light, there is a real possibility of scratching them. And then there is the cost of course!

In the end I went for glass although I can see that it would not be possible to make your folded design in glass (at least not easily).

Anyway James, welcome to the open-baffle club, clearly better sounding and clearly better looking!

Hi Nuuk,

Love your website! Nice piece of work.

Modern perspex is available with good resistance to aging via ultraviolet colouring - particularly if direct sunlight can be avoided. However the cost is high. For me it was the only way my wife would accept having the design in the house - she refused the glass designs I generated...

Acoustically they have exceeded my hopes for them - and continue to get better and better. I couldn't go back to closed boxes again...

Clearly better indeed! In all senses of the word!

ciao

James

No, this is a one-way trip as those of us who have made it have found!

I recently went to a hi-fi show and all that I could hear in any of the exhibitors' roooms were 'boxes'.

PS Thanks for your kind comments on the web site.

Well, I've always been late for everything ... and I'm a couple years late on this thread.
I'm a lover of the boxless sound and also couldn't return to conventional enclosures.
I am full of admiration for John, and anyone who undertakes a brave project like building from acrylic ... you can hide your mistakes in wood (and believe me, I have to do some hiding at times!)
The pics are gone now, but I'd love to see them - is this possible?
