Plexi-Glass Baffle ?

Robertburchell · 23rd May 2006, 05:57 PM

I just read a thread about Glass enclosures, And I dont want to hijack that one so.. Ill start my own

Would it be alright to build a front baffle for a speaker out of plexiglass ?

Well, Ok, I'll allow it.

Sure, why not? Magnat did an all-plexiglass enclosure years ago that was quite beautiful. As mentioned in that thread, the issues with plexiglass is that it is soft (compared to glass) and easy to scratch.

A heck of a lot easier to work with compared to glass tho...

add less prone to breaking. My wife wants me to replace drab baltic birch open baffles with 3form ecoresion panels. (http://www.3-form.com/ ). Note a 4' x 8' x 3/4" sheet can cost 2k. I haven't inquired but I think you can have them cut, machined, and even bent to your specifications (at a price of course).

Hi,
You need a thick plexiglass , which is very expensive.Try to compare how thick plexiglass is required to be as rigid as 18mm plywood , for example.

A long time ago, I bought a pair of plexiglass panels and mounted 4" Phillips full-range drivers into the middle of the panels. A friend liked them so much, he bought them. That project sure paid for itself!

PS: The panels I used were no more than 1/4" thick, maybe around 2 by 3 Ft in size. It was smoke collored and freestanding on wood blocks. Just open panels with a single driver near the middle. Not bassy of course, but sounded fine! If resonances were in the panel, it was not very obvious. I think I paid less than 100 for the pair of panels back then.
