Attached is the write up for my all Dayton RS 3-way.
This project uses shielded RS150S-8 mid and RS225S-8 woofer. I used those as that’s what I had available. To answer the question if you can use the non-shielded versions, I’d say they would be very close, but the tweeter padding resistors would need to be adjusted.
The uniqueness of this design is the use of a high quality aluminum midrange driver open baffle.
The Dayton RS225 is in a MLTL enclosure. The stuffing is .75 lb. per cubic foot Dacron or fiberglass. I used fiberglass contained inside a thin polyester quilt batting “pillow” shape. The box is ½ inch MDF with 45 degree mitered joints. The center box divider is ¾ inch MDF. The box is finished with sprayed Kona Coffee colored acrylic latex over shellac based primer. The top coat is sprayed satin water based polyurethane.
The front baffle is glued up ¾ inch stock. The wood is Soft Maple, Walnut, and Cherry. The front of the baffle has a ½ inch round over. The back of the baffle has a ¼ inch round over. There is a routed wire way in the middle for speaker wires. Remember to plug the wire way/ hole when it enters the woofer box. The front baffle is lag bolted to the box. The finish is sprayed oil based satin polyurethane.
The port is 2.75 inch cardboard tube. The front port has a ¾ inch round over.
The feet are “furniture legs” from KE Hardware. The feet are mounted on angle blocks that are glued to the MDF sides
The cross over is mounted on a separate board under the box.
Judges comments we very favorable from MWAF
A few people wanted to see the X-O BOM so I'm attaching.
Let me know if you see any errors or omissions
