Is anyone else looking for their 1st active project?
How about a Modular 3 way shared design. What I mean is a system with the same tweeter and mid combined with a bass module depending on the size of room / requirements.
going active is daunting, and I want to remove as many of the mistakes as possible.
A shared design & configuration would remove a lot of the guesswork.
I don't have the overall budget for something like John K's Nao Note sleakers, otherwise that would be my first choice.
I am following the Freedsp 2 thread, and its very near finished and begging for a project. Hopefully it will cost a lot less that the mini DSP 8 channel. It uses Sigma studio, I had a quick look and Sigma appears more complicated than MiniDSP? I have a UMIK-1 measurement mic and have just started using REW.
Having a low cost design with the same amps, psu, speaker system would be very appealing. . A baseline crossover config to load would be a huge benefit, then use the room correction or REW to measure and adjust for each users room. We could share measurements and configs and design changes etc.
If we set a budget of up to $50ish per driver, up to $200 per speaker, should give a wide choice.*
An example might be;
Open Baffle for Tweeter & Mid, sat on top of Z baffle bass unit.
Amps could be TD3251d2; 1 chip in 4 x se for mid & tweeter and 1 chip for bass.
Or 3 x TDTPA3116D2 etc.
SMPS PSU.
Use best suited Ohm drivers for amp output
What about Dayton ND tweeter, this one has a wave guide;
Dayton Audio ND25FW-4 1" Soft Dome Neodymium Tweeter with Waveguide 4 Ohm *$20 x2 = $40
Or an AMT / Ribbon on top of the Vifa etc.
Vifa mid
Tymphany TG9FD-10-04 3-1/2" Glass Fiber Cone Full Range *$20 x2 = $40
GRS 15” woofer x 4 $100
GRS 15PF-8 15" Paper Cone Foam Surround Woofer
Drivers $180 ish
Anyone interested in a project like this?
This is the direction I am hoping to go in.
