DizRotus Posted July 19, 2020 Share Posted July 19, 2020 The built-in speaker in the small Hitachi TV in our kitchen developed an annoying buzz. Alex Trebeck with a lisp is no good. A solution seemed to be the DIY project speakers (shown below) sold by Amazon for less than $20. What a major disappointment. The ultimate SQ was horrible. Even my wife said, “It sounds muffled.” I ranted about the Amazon speakers in the thread below, so I’ll not repeat that here. A solution for the solution seemed to be a pair of tiny Visaton drivers from Parts Express. They sound way better than what came in the acrylics. This way I can still use the tiny chip amps built into each enclosure. The Visaton drivers more than triple the cost of the project, before adding in the cost of glue and sealant needed to stabilize the acrylic enclosures. My wife just shakes her head at the disassembly of the new project to invest even more time and money. I had to remind her, it’s a hobby, not a business. She admitted even she is growing more annoyed by the TV speaker’s buzz. I’ll add some pics of the completed project. Quote Link to comment Share on other sites More sharing options...
DizRotus Posted July 19, 2020 Author Share Posted July 19, 2020 Now on to plan C. Saving that crappy acrylic was a fool’s errand. Despite being just the fool for the job, I elected to re-purpose a redundant Pono bamboo box. The project is stalled due to much needed rain forcing me inside, as well as the need to go to my son’s house for some files with which to clean up the speaker cutouts.

Davecv41 Posted July 19, 2020 Share Posted July 19, 2020 Do you have a drill press? A hole saw or a flycutter make cleaner holes, but the work and the cutting tool need to be steady, both for neatness and safety. Quote Link to comment Share on other sites More sharing options...
DizRotus Posted July 19, 2020 Author Share Posted July 19, 2020 Yes to drill press. This method will work fine. The box will be hidden by the TV. It needs to function, not look pretty. I probably should call this plan D, as I was intending to drill holes to act as grilles, but soon decided to remove the circles totally.

DizRotus Posted July 20, 2020 Author Share Posted July 20, 2020 This ended up like George Washington’s axe; five new handles and two new blades, but it occupies the same space as the original. All that remains of the original are the chip amps and some of the wires. 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted July 20, 2020 Share Posted July 20, 2020 If you need grills and have old pc parts laying around, for small speakers you can use the grills from the computer fans. This one is off a small case fan... 1 Quote Link to comment Share on other sites More sharing options...
