I have been looking to upgrade my 2 channel speakers the last couple months. I have been looking at the spatial lines and also the GR Research NX Tremes.
I have NEVER built speakers before...I do wood working so assembling the flat pack would not be an issue but not sure about getting a good finish DIY. I have also never built a cross over before. I can follow plans etc so that shouldn’t be difficult.
Can these be made and still be made “right” by a newbie DIY’er?
Welcome to the AC!
Getting a nice, smooth finish on wood is rather easy if you opt for a satin finish rather than high gloss finish.
For a high gloss, mirror finish, you would need spraying and polishing equipment and a willingness to do some extra, ultra-fine sanding and abrasive polishing steps.
I prefer oak with a satin finish, using the following steps:
- Sand the wood smooth using 220 grit
- Wipe on an oil base stain (Min-Wax or other) and dry for 8 hours minimum.
- Spray or brush apply one or two coats of satin polyurethane (Min-wax or other)
- Allow to dry for at least 6 hours
- Lightly sand with #320 or #400 grit. You don't need to cut deep-- just flatten the nibs
- Spray or brush apply one coat of satin polyurethane.
The above alone is sufficient to obtain a very nice satin finish.
And if you really want to take it to the next level of smoothness and perfection; lightly abrade with ultra-fine steel wool and then apply a coat of butcher's wax (only).
My DIY speakers in the video and photo below were finished in satin polyurethane but I didn't go the extra step with steel wool & butchers wax:https://youtu.be/Q_4sddiBEoU
