I have made a lot of prototypes, but nothing that has stayed in the living room. I am now building 2 surrounds that will.
Before I realized the amount of work and money a nice cabinet took, I planned on building fronts with Dayton RS100's and a small neo-tweater to learn. I was already planning on replacing them with something better once I knew what I was doing, and decided to skip the first project. I've been playing with the Esoterics, but that is expensive and time consuming. I wanted something simple I can actually use in the near future.
For surrounds, I currently have a 7.1 system hardwired to my receiver with very cheap speakers. I have a wireless Dayton Audio XRA25 that will work with the sub and power 2 speakers, supposedly at 25 watts into 4 ohms. The plan is to gain WAF by eliminating wires, and improve sound by upgrading 4 crappy speakers to 2 better DIY ones.
I need something:
high efficiency into 4 ohms.
don't need to be full-range, but base extension is nice to have.
not necessarily ruler-flat, but decent audio quality without too much distortion
a high WAF
Sealed box for placement flexibility
The RS100-4 were a target on my early prototypes because they can play low for such a small woofer, and has low distortion and reasonable quality. I already have them, and they are perfect for this project. To gain the efficiency I need, I plan on 4 drivers in each box. Each box will be 5x5x24 inches high - close to the recommended size, high enough not to need a huge stand, but thin and small enough for WAF. To cut costs, I am eliminating the neo-tweeters (cost of crossover parts) which leaves me crossover-less (probably need a notch filter), which makes this a very boring build as far as electrical engineering and acoustical adjustments go. Still an adventure for me, as it will be the first time I try veneering something. I am hoping comb-filter isn't much of an issue, but it would be a possible issue even with a neo-tweeter. Surrounds make noise (bullets, explosions, etc) during movies, so hopefully the top-end will be acceptable.
Right now, I am trying to decide if I need bracing, and how much to use.
