Barium - Small two-way with Atlas ribbon and SB ceramic woofer.

edited June 15 in DIY

Named from the Greek word meaning “heavy,” Barium is a soft, silvery-white metal. This small ~ .25ft^3 two-way will feature the recently released RAD Atlas AR120 tweeter paired with the SB Acoustics SB12CACS25-4. Cabinet dimensions will be 11.5" tall by 6.5" wide and 10.5" deep and will feature walnut sides, oak tops/bottoms, and painted front and rear baffles. The woofers were exercised today with hopes of some basic T/S data collected soon. Cabinet pieces are in the process of being cut. The baffles will be .75" MDF while the tops and bottoms will be 5/8" scrap oak flooring. The sides will be a sandwich of 1/2" particle board and 3/8" walnut. More to come...

  • Cutting and trying to flatten a bit of cupping in the walnut.

  • Baffle CAD with 1/2" chamfers.

    Glue up has started.

  • Each and every speaker project reminds me that I'm not much of a woodworker. After struggling with getting the top, bottom, and sides squared up I was able to glue up the first one and flush trim the walnut.

  • Your not the only one. I'm just getting better at covering up issues.

  • Me too. A master woodworker told me "Just make it look good from 6 feet"

  • Unless you are feeding your family from the work, the result is all that matters.

  • I like your choice of wood.

  • That's looking pretty good to me!

  • First final baffle off the CNC.

  • Curious if your top panel feathers a bit after some stain/finishing.

  • I effing love using a CNC for baffles. I often made booboos with a router.

  • I appreciate the comments, let's hope the glue holds :)
    I had to calibrate the CNC as my Y axis was right on, but my X axis was a just a bit short. I'll be doing hard wax oil for the finish. I'll shellac the MDF and then paint it.

  • Which hard wax?

  • This wax. Started the second cabinet and glued the back on the first.

    Thanks. Had not seen that product.
    I have used a lot of Tried and True finishes.

  • Just direct wax, no other sealer? I use hard wax, but once I have sealed with shellac or a water based finish like generals

  • Yep, from what I understand, the hard wax oil needs to soak into the wood. Flush trimming the back on one and putting the other side on the other.

  • The first cab has all six sides... hurray!

  • CAD'ed up and now printing the ports which will use 1.5" ABS elbows.

  • Both now have baffles and one has been flush trimmed. I still plan on on adding the chamfer to the sides of a baffle.

  • That should be a nice driver combo. I think they are going to look great! Hope with their smaller size that you don't experience any issues with the hardwood's movements in different directions with temp/humidity changes.

  • Thanks. I hope that since the oak is plywood backed flooring and that I glued the walnut to the particleboard, I'll have better luck....fingers crossed.

  • Not quite a friction fit on the elbow, upping the diameter. Verified the fit for the 2" hole in the cab is good. Actual inside port diameter is 1.6" by 9" long.

  • Both have their 2-in port holes drilled and one has been chamfered. Waiting on my 15/16 forsner bit for the speakON connectors.

  • Got the baffles painted the same color as the living room cabenets - Cityscape.
    Applied the hard wax oil and waiting to buff it out.

    I can't wait to see how cool they look with the Atlas tweeter and white CAC cone woofers. Should be striking!
