Absolutely. One could cheat a bit with an aluminum mold. Those are a lot cheaper, but also aren’t made for tens of thousands of units. I’m not sure though if they can actually be used for larger molds like for speakers.True, though just the mold of that size is extremely expensive.
I think the major reason to use plastic for PA speakers is the much lower weight. It makes transport and installation/deinstallation cheaper.For PA, sound leakage from around the cabinet is a less big deal, the enclosures tend to have simpler internal structures, and they tend to sell more units per model, so it works.
Good point. Having moved and set up enough plywood PAs in my college years, I think this is a major design consideration!I think the major reason to use plastic for PA speakers is the much lower weight. It makes transport and installation/deinstallation cheaper.
To give some sense of scale, the mold for a ~25L speaker we made was >$250K and that was over 5 years ago, and we got a very good deal on the mold. Also, the plastic isn't free, but it's definitely cheap. As you go bigger the cost will rise faster.even if a mold is € 200k.
No,no,it's not visible.The ones I have seen at least.Probably marketing / aesthetics. People see carbon fiber and they think "high performance" regardless of whether it makes sense.
That makes some sense. It's the kind of material you can use to create a curved but highly rigid surface, which I think makes sense for a WG.the only visible fiber carbon part was the waveguide of the tweeter
Oops forgot to say, these speakers are all used in commercial movie theatres.JBL 8320, JBL 8340 ect. All plastic based. Cheap second hand and sounds great for compression driver based speakers.
Probably to get the benefit of dissimilar materials and a quasi-constrained layer damping effect. Otherwise the aluminum could still "ring through" certain frequencies, no?I wonder why they add a carbon fiber shell when it has a (stiff) aluminum frame. It's like if Genelec wrapped their speakers in carbon fiber.
and i still dont get why that speaker cost so much...The KEF Blade 2 cabin is technically made of plastic
Because they can! I was considering a pair but I can’t justify the price for what they are especially since they jacked up the price so much!!and i still dont get why that speaker cost so much...
