I’ve been considering upgrading my Goldenear LCR to some diy designs. I was looking at various proven designs, but traditionally love ribbon, planar, and AMT tweeters.
I ended up getting a decent deal on 3 Beyma TPL-200/H’s. So I’m completely skipping the basics of DIY speakers and jumping off the deep end with a full custom build.
My plan is three way active, with the tpl-200h, an undecided sealed mid, and the 18ds115 woofer ported.
I hope to find crown dci-n amps to use for power and processing. If not, I will get an ashly 24.24m for processing, and use my current analog dci amps.
Planning 1200hz crossover mid to tweet, maybe 350hz woofer to mid.
For mids, I’m currently most interested in the AE TD10M and TD12M, and the Beyma 12p80ndv2. I’m open to other suggestions.
The ae’s seem to be considered the reference mid, while the beyma is significantly cheaper, higher sensitivity, and has more motor force.
The faital 12fh520 and 12pr300 look promising as well.
The 18ds115 will be in 5cu roughly, tuned to 35hz.
I already have 2 of the 18ds currently in mini devastators, and picked up a third open-box recently.
The mini dev’s will be swapped to a modified version of the mini 21 v4, loaded with nsw6021’s.
I haven’t had time to do much modeling yet for volumes.
I plan to build the woofer modules to 25.5” high x 24” deep x 20” wide. This matches the mini-dev profile and will give me a size-matched front lineup.
Here’s the current setup:
There will be a woofer module between the mini dev’s, and one on each end.
Eventual plan is an at screen even with the front of the cabs. Is there a problem with having the mid and tweet farther back than the woofer?
Since the at screen and new projector are a ways off, this leaves me two options for the center. First is to use my current center and the woofer module as a two-way.
Second is to build a horizontal mtm with the beyma and some 8” mids. The faital 8pr200 looks like an excellent driver. Since I’ll be running 3-way, the b&c 8pe21 (Edit: scratch this one. 8mbx51 and 8mdn51 have potential) may make more sense though.
I should have available processing and amp channels to run this 3.5 way, if that would help.
I’m just at the start of the process, and know I have lots of modeling in my near future. Followed by building and measuring.
I will be able to do outdoor measurements on these.
I’m hoping for some guidance, whether I’m even on the right track here.
Driver suggestions for mids are also appreciated.
, I believe you use the similar tpl150h’s, the beyma mid, and the faital 8’s. Your guidance would be particularly appreciated.

They’re a whole different scale.
