Sub project double-check

[NNYbuilder]

Wanting to see if I'm missing anything....

Dayton Audio SA100 100W Subwoofer Plate Amplifier

Bravox PXW15D-2 15" DVC Subwoofer 2 Ohm Per Coil, wired 4 Ohm mono

Precision Port PSP-6OFN 6"

22" x 22" x 38.5" High external 3/4" MDF cabinet

Sub to be mounted in face, centered both ways. Amp mounted high rear.

6" x 1.7" port in 22"x22"base. ***Is using a port without a tube like this a problem?

Lined with a fiber insulation board (Celotex, Homasote etc.). Glued, screwed, sealed appropriately.

For finish: 1" x 1/4" strips of black walnut applied in a herringbone pattern. Sides and top in a rough slate tile, rear varnished or flat black on the MDF.

***Should I buy or make spikes for this, or can I just make wood-block feet and dowel them on like I would furniture? It should be well- weighted.

Looking forward to your input.

Your 6" id vent needs to be 9" long. Tunes box to 25Hz, and skirts just shy of Xmax @ 100w.

If its going on carpet, DIY wood feet should be fine. If its going on a hard surface, I'd use rubber feet. If the carpet is really thick, maybe pointed spiked feet for stability.

Thank you both. I consider my questions answered.
