chorus,
Not to get off subject, but if you’re going to have your tools out anyway, a simpler DIY project with much higher return on investment vs. store bought is building your own acoustic panels since the room dimensions and how it’s acoustically treated will have the biggest influence on how your speakers end up sounding.
GIK Acoustics carries Knauf’s ECOSE material, much better to work with than fiberglass, and some Guilford of Maine acoustic fabric gives you top quality components. For frames, use premium pine one-by (3/4” actual thickness) trim the appropriate width and assembled with glue and pocket screws. Get fancy and add some gussets in the corners to help position and hold the material and you’re good to go for absorption treatment.

Very impressive cabinet build - no plain wooden boxes there! Enjoy your Tannoy project.
