The Revelations

A build based on the 8" Silver Flute, 5.25" Silver Flute & Seas 27TBFC/G.

Named NOT because they'll be the end-all of musical production, but because they will be the LAST time I do a lot of the techniques I used. They have been a huge learning experience and, in many ways, exceeded my expectactions.

  1. I've got some ideas about rebuilding the enclosure with some changes. One, more braces. Two, using hardboard (or a combination of hardboard and...

  2. Final XO tweaks to account for the change in tweeter. Yes, I know my audio rack isn't centered.

  3. System response, accurate to ~150hz. Lots of bandpass gain, but also lots of smoothness to the power response. I'm quite pleased!

  4. Shellac is very cool and also the devil. The alcohol evaporates SO fast that you can't help but get streaking from hand-application. So there was a...

  5. Almost done. One last clear 2lb cut across the top to mitigate the swipe streaks.

  6. Drivers installed, with the Seas 27TDFC/G now playing role of soprano. The hard flash really shows the depth to the finish. Very different under hard...

  7. Test fit. Drilling the countersink holes for the screws.

  8. Driver test fit. The tweeter is the MDT-37 (not what I finished with). They got VERY big and very real when I brought them into the house. Exciting.

  9. Final pieces of veneer, just before trimming.

  10. Routing the fronts with the same method.

  11. One down. Front edges are nice and flush. Mating the front baffle will be easy. You can see the 1/2 round of 8" sonotube for the midrange...

  12. Front baffle is 1.5", all the routing is done. My little Rigid contractor's table saw did the angled cuts without batting an eye.

  13. Wrapping the first layer of 3/8" bendable ply around the cabs. I used considerable overhang to get rid of alignment woes.

  14. My overhang got rid of alignment woes, but created another. How do I flush-trim the overhangs?

  15. I ended up attaching a temporary board and then using that as a bearing guide. I set my router to a depth that matched the rear baffle and went to...

  16. Template, from which all other pieces will be cut. I printed a top-down view from Sketchup, 1:1 on 4 pieces of paper, then glued them to the MDF and...

  17. Backs and all ribs cut!

  18. Assembly begins. You may note that my little triangular wedge piece is missing. My joinery was surprisingly square and I got lazy.

  19. Sketchup design, with grille (that I don't think I'll ever bother with)

  20. Internal view of ribs. The slat across the front is a temporary piece to keep all of the ribs aligned.

  21. Sketchup. Exploded view.
