So I had 4 extra of the HDS Nomex 164 mids (830875) laying around and decided to try and make use of them. I then found a design that utilizes 4 of them: PEERLESS-NOMEX-164 (http://www.troelsgravesen.dk/Peerless_HDS830875.htm)

This is practically my first worthy home audio build (noob).

The cabinet will be made out of mdf. I'm unsure of how to finish them. I've never veneered before, so I might just paint them somehow. Possible some textured paint.

Drivers:

Peerless HDS tweeter 810921 (also Scanspeak D2608/9130)
I've had these install in my car year ago. I liked them a lot. Very smooth detailed and easy on the ears. I'm sure I'll be pleased with them outside of the car as well.

My only experience with these was hearing them in kickpods in a tin-can '93 civic hatchback. They are capable of a lot of output and can be very snappy in the midbass region. Due to the environment and lack of tuning, I will not comment on their midrange.

On to the build

Baffers:

With the truncated flanges, some extra steps were involved with the flush mounting of the mids.

Then flush cut the cutout on the bottom layer

Next was to predrill the mounting holes with a centering bit:

Not the straightest cuts on the inside, but oh well.

The crossover

I'm quite the noob with both the solder iron and crossovers. If Troels didn't include a picture of the finished crossover assembled, I'd probably be lost.

MDF Port:

I had extra mdf, so what the hey

Flared on both ends with a roundover bit:

looks like a surprised bunghole, imo.

Now I wait for the binding post to arrive before fully assembling.

I recently build a subwoofer and wrapped it with 1/8" or 1/4" (whatever size it was) oak plywood, the kind you use on the sides of kitchen cabinets. You could do something like that then put corner molding all around, just a suggestion.

i'd try and replicate the look they used in that link of the build instructions.
theres alot of really helpful veneering walkthroughs on the net:

Thanks for the link. I will keep it in mind.

The original look of the design won't match any of my furniture. I might just spray it with some textured paint.
