A while ago I was on parts express and found some interesting drivers on closeout so I bought a bunch of them thinking that I would make a bunch of desktop speakers from them.
I have eight WFR0400211 and eight WFR0400215
They've been sitting around on a table. I think that they look really neat all grouped together in a square shape. now I have my heart set on using them all together in one speaker. The idea is to make two speakers with lots of drivers around the same size in two thin wall mounted cabinets that can be put side by side to look like one unit. The overall shape being like framed art.
I have these other drivers picked out (haven't modeled anything yet)
sixteen of ND105-8 eight per side.
and six of BC25SC06-04 three per side.
I'll also be using two 2x4 HD miniDSP units as crossovers.
I'm looking to have the amplifiers and power supplies independent for each cabinet, built on the outer sides under a glass pane so that they can be seen with nice colorful cable routing with toroidal transformers and caps and maybe have it lighted.
I know lots of tiny drivers isn't really a practical approach, but this is more about the visual interest of the whole thing, while still sounding very nice.
Questions:
I'm having a hard time picking out amplifier modules to use. The Sure boards on parts express seam to be the best fit for power and economical, but I'm worried about fan noise, and the more I read about them the worse they seam from a quality perspective. Are there better options for this project? I'd like to be able to mount the mosfets/ic's directly to a large heatsink rather than use fans.
Using the two slightly different WFR drivers, I know it would be better to use more of one type of driver for the upper midrange and let the ND105's handle more of the low end. I think it should be ok to split the midrange between the two, with the 215's in smaller enclosures and the 211's in larger enclosures tuned lower, with the ND105's used as bass drivers only. Should I give up on using both types of WFR drivers? It's already going to be an expensive project, I'd like to not buy a different set of midrange drivers.
