Project Category:
Portable Speakers

Project Level:

Project Time:
1-8 Hours

Project Cost:
$100 – $500

Project Description:
24″ Bluetooth with rechargeable battery.

Design Goals:
This is my 3rd project and with each one I continue to apply lessons learned from the previous version(s). I also wanted a more finished look with this one and added the grill. The grill ultimately gives me more options for color combinations. With each revision I’m trying to get where I can duplicate and make them efficiently. Ultimately offer these for sale at a “reasonable” price and good quality and style.

Driver Selection:
(2) HiVi B3N 3″ Aluminum Driver Round Frame.

(2) 1TD2-8 1″ Designer Dome Tweeter 8 Ohm.

Enclosure Design:
24″L x 5.5″W x 6.5″H Oak.

Enclosure Assembly:
Basic butt joints and a lot of finesse

Crossover Design:
Only a high pass.

Tips & Tricks:
1: I say it each and every time. Be careful with your space for the electronics. I have run out of room on EACH of these and had to fine a work around.

2: Use a fortsner bit or other to hollow out the wood in front of the bluetooth board. Or, create some openings. Does wonders for range.

Turned out well and I think the next version will quality enough to offer it up for sale and hopefully someone out there wants to buy it LOL.
