Thanks for your input chaps.
Rather than glue, and if your wood working skills are up to it! Create a recess in the area, slide your glass plate in. It can then be removed easily for cleaning.
Bit like the JBL L300 concept.
That looks interesting in that execution Jon. Although, TBH, I don't posses the woodworking skills to begin cutting channels and I would be lying if I said that I was prepared to put that much effort into the job.
I am thinking of a simple CD sized 5" carbon fibre disc to cover the mess..... That will retain most of the lovely veneered top with a little twist to create both a visual contrast in materials and shapes and might create a visual intrigue without looking too out of place? I hope....
Those look like a good find. They're a reflex, so what goes on inside the cabinet is important. The BAF wadding will damp midrange resonances and leave the bass untouched, which is what you want. The only thing we've found which beats it is Twaron Angel Hair. But it's very fine stuff so it would be worth getting a light mesh bag to put it in before putting it inside the speaker (eBay and Amazon sell light laundry bags which work well for this).
Wool tends to work at bass frequencies, so may not be ideal for these, and may also upset the reflex tuning by increasing the apparent interior volume that the driver 'sees'.
Hope that's of some help. Good luck with them.
Thanks Colin, Very helpful indeed. I'm not finding anything other than the links I posted so every contribution is most welcome. The Angel hair is very interesting because I was looking at cashmere wool and although it may not work as effectively as Twaron it's nice to know that my thinking was blindly heading in the right direction
. The quantities suggested are a little vague and could easily triple the price on a guestimate. 3-10 gm per litre @ 24 litre. The BAF weighs 233 so a little under 10g per litre. According to Mundorf they claim that 10-20% of comparable BAF is the required ammount. Would it be likely that these cabs will require more than 100g each? I appreciate that this is not a reasonable question to put to you, but.... experience really is priceless.
Would it be detrimental to fill the small gaps inside where the bracing meets the rear internal veneer with Ronseal high performance wood filler to make the rear face comletely flat, or will any interference with the cab complicate the performance? I am considering painting the 'chipboard' braces and the top of the sand/shot box with non shrinking cellulose dope to stiffen them. ...... or.....Am I just digging myself into a hole of amateur enthusiasm and ignorance?
I am looking at things where the manufacturer builds to cost, and a little more can yield a better performance.....
If you want to improve the crossovers replace the ferrite cored inductors with air core inductors - easy to wind yourself.
I've listed the component values of all but the inductors which give no indication of anything. I can't find any schematic or threads elsewhere. I want to spend a little more on better components but I'm stumped by these things despite reading around. I'm out of my depth on these as a simple part number is absent so I'd be gratefull for any advice on where to go with these.....
