Here is a speaker enclosure for Soundtraxx 810078 28.5mm x 40mm large speaker. I make them from black ABS plastic. They will make your speaker sound better, louder, and provide better mounting options. Check the picture for exact dimensions. 810078 speaker fits perfectly inside, with hole for wires (fits up to 24 gauge, enlarge if needed). Hopefully this saves you the time and effort from having to make your own.

Decided to sell these individually again, instead of in pairs. That way if you need 1,3,5 etc. you have the option. I also reduced the price. I was able to do all this only because I took the free shipping away. (USPS hiked rates, so I had to do something). If you order multiples, you get a discount on the item, and also shipping is discounted (only 5 cents extra per additional item). Make sure to buy multiples together (at the same time) to get the discounts!

I also sell speakers, including "sugar cube" speakers, which are tiny, inexpensive, and sound great.
