Amiga tower speakers build thread
« on: October 27, 2014, 03:45:57 PM »

My mother is redecorating her living room and got a nice reclaimed wood entertainment center and now wants to change her speakers. The current speakers are nothing special, an old pair of Yamaha bookshelves with 8" woofers that were probably $50 each 20 years ago. She doesn't like stands so she wants full towers, and she doesn't want black. The catch is that the stain used on the entertainment center is dark brown, where most inexpensive tower speakers with a 'wood' option are cherry, which would clash.

So, does anyone know of some relatively inexpensive tower speakers ($500 or less per pair) that are available in a dark brown?

Here's the best match I could find for what she has:



The other path would be a DIY kit in the same price range that I could make and match stain, nothing too complex and again within budget. These speakers are mostly used for TV/Movies. Any options there?

One option I found quickly is this: http://www.diysoundgroup.com/speaker-kits/amiga-kit.html and the cabinets: http://www.diysoundgroup.com/flat-packs-1/amiga-flat-pack.html which I could veneer and stain.

Looks like that might be for just 1 speaker. Also too much red in it. I've been looking a while now, and I think my only options will be DIY so I can stain it myself.

Ordered a couple Amiga kits. Only thing I think I am missing is internal wiring. Any suggestions for types and how much length I should get?

Looking around, it seems simple 16 gauge stranded copper is sufficient. I'll get some from Monoprice if I don't have enough left on my 12 gauge spool I made speaker wires from for my house.

So I got the kit today and there are no instructions, so I'm winging it. One part I am not sure about is the crossover. I have the diagram but would love if someone can check my layout. Some you can't see the values, but they do match.



Also, I can mount all of these to a wooden board without any problems, correct? I would probably get some adhesive backed foam to attach them so they can't rattle.

Yes, you have the structure right but make sure you wire parallel components back to ground

Yes. Attach to wooden boards. Drill holes and run wire ties to secure. Hot glue to make sure parts don't vibrate.
Be very very aware how the inductors are laid out: http://www.troelsgravesen.dk/coils.htm

Thanks OJ. I just ran across this picture that shows it assembled.

Edit -

Thanks for the tips, Marv, especially the coil orientation.

Got started gluing the internal braces into the CNC'd slots on the rear panel. Also have the crossovers about half done. The zip ties I bought were too short for the large coil and the 2 larger caps so I've got to get some longer ones, then hot glue everything down and start the soldering. Before I add any more panels, I need to figure out what kind of foam I can get locally to line the walls, and cut pieces and glue them in while they are still apart and accessible. Some people used mattress topper, the wavy stuff, but I'm not sure where to get that, or if I even want it. I had thought the kit came with some poly fill, but I guess not. I wonder how much I need for this speaker.

Going to Woodcraft Sunday to pick up the veneer, probably walnut. The guy who made the crossover above did his Amigas from walnut veneered plywood and it turned out nicely, though I wouldn't have painted the face black.

To line inside of walls, under-carpet felt stapled or Sonic Barrier (self-adhesive) from parts-express. Very light or no stuffing if box is ported.
