[English walnut] is prized by fine woodworkers for its durability [and] luster, and is used for high-end flooring, guitars, furniture, veneers ... (Wikipedia)
Searching for the Blues – a Bavarian building report. Which one of the Blues Class speakers would it be?? A trial listen? … Hmm, it was 700 km to the listening studio. :( So that was out of the question. But then I read the article “Ich hör auf”!! Gulp. Well then. The Audible, ending up with something like that after a quasi reboot… in my opinion, there’s a huge amount of passion in it. Thanks !
Time to get to work
Naturally I discussed the design issues with my dear and very tolerant wife (thanks sweetie!). Okay, they would be painted white. Or not, as it later turned out. Off to the hardware store with my wood list, color ideas and anticipation.
That evening, I told some close friends about my plan over a companionable drink. The “horror stories” that came out of my good friend’s mouth – he’s an experienced painter – about painting, spackling, sanding, spackling and sanding again… etc. … that’s no job for a wood hobbyist, so no paint after all.
Ponder ponder, what kind of outfit would suit them, I wonder? Off to my trusty lumber shop to take a look. What did the forklift pull down from the high rack? Take a guess – sawn walnut veneer, 7 mm thick, 6.2 m long and about 30 cm wide. What a perfect fit. We quickly cut it into trunk-friendly pieces about 2 meters long, and I took them down to the basement. I let the beautiful wood warm up for a while, since it was freezing cold out.
Ready to go: cutting the MDF to size and tossing it into the gluing press. No, I’m not a cabinetmaker, just a wood hobbyist with a pretty well-equipped workshop. A man needs a hobby, after all! I used the assembly plan as is, except for attaching the front in 16-mm-thick MDF so that I wouldn’t have to change the reflex channel. So the raw cabinet was in the press, which means I had time to build the crossovers, which were attached to two scraps of wood with hot glue and then went right into the cabinet. I put the lid on, and now the two speakers were ready for their nice outfits.
The front and back were given a single sheet of the beautiful walnut because my planing machine can just handle that width. The side pieces were split and forced together with adhesive strips. The gluing sequence, with a combination of PU and D3 glue applied in wave shapes: back, sides, lid and then the front. I scored the smooth MDF surface crosswise with a chisel to give the glue something to hold onto.
Next came the good old Elu router, with a routing template made from a piece of scrap wood, and as sorry as I was to do it, I cut the holes out of the beautiful wood. I also cut two 16-mm holes out of the lovely back, for the terminals. Sorry, I couldn’t subject the walnut to the plastic boxes that came with the assembly kit, although they would have done the trick.
Almost done, now it was just time to sand and oil them and install the fetching chassis elements. I used a belt sander (#120 grit) for the sanding, and dampened the wood first. Then I finished it off with sanding pads, which makes the surface especially nice for audiophiles. The final treatment for the “Nussis” was a high-end poppyseed oil, which consisted of a mixture of 10 TB poppyseed oil, 1 TB orange oil and 1 TB turpentine oil. After an hour, you can polish the whole thing with an old sock. It smells nice, too – the oil, not the sock, obviously. A little note from the dear wife [“Lookin’ good!”] always helps, too.
I quickly glued on the super-audiophile cork feet (€1), screwed in the chassis elements and stuck in my homemade strips from the PA department… now it’s time for a GAM session.
How do they sound? Damn good… WAIT... NO!! The stuff’s still attached to the TV. They are just indescribably, FANTASTICALLY Blues Class-great!!!!
