Being recently retired, I’m finding things I’ve collected in my garage.
I was given some cheap Sony 12" 3 way speakers that sounded terrible many years ago and decided to work on them, I located some NIB 6x9" dual cone speakers that I bought in the early 90’s that I never used. I removed the front baffle where the old speakers were and replaced the front with leftover particle board. I used a formula on the web to calculate a port size using leftover 3" ABS. Then I went on AMAZON and bought these 2 way crossovers with wire posts all in one for $5EA, tweeters for $11EA, some pillow stuffing for inside.
I cannot believe how good these junk speakers sound!
I bought a Fosi B20A mini blu-tooth amp to power them. $90
Unbelievable sound! Loud too! Bass that you can feel like some high end audio!
Yeah then I had these little Bass reflex things that I screwed into the boxes.
Not powered speakers, but reacted to the air movement to give the bass a little more pop.
I have a giant pile of 10 HP 3 phase motors that I saved to separate and recycle.
I am saving the bearings for axles on gokarts that I want to build powered by snowmobile engines. I have lots of ideas for projects brewing.
Mid 80’s, I was in my late teens. I had a convertible (still have it, actually) and we took it to the beach often. I bought some stupidly expensive (for the time) JBL 6x9’s. Cast aluminum frame, nothing like what they currently sell. I mounted them in boxes, so we could prop them on the folded down roof, while cruising on the beach.
One day, a friend was having a party. We got curious, and brought the JBL’s up, and hooked them to his home stereo. He had typical floor speakers with 12" subs. My JBL’s were WAY fucking louder! For the next year, they had me bring the JBL’s for all their parties.
Back in the late 70’s I was in to building stereo systems for my friend’s cars.
I would blend the boxes into the interior. Built the cabinets in HS wood shop.
Tell them what components to buy and I would install them. I would build the crossovers in electronics class. But I was only in there for that. It was just a hobby and gave me projects. I never thought about the future of car stereo business. I was too into partying.
I have another speaker project for a home theater, I bought 6 of these 5.25" mid-bass drivers, 6 silk dome tweeters, and 6 2-way x-overs many years ago. But the VAS was too high for my liking. The VAS is a TS parameter that you need to tune the cabinet. So they were never built. Yesterday I found them so I decided to use passive radiators with them. I found some that were cheap enough at $13EA. I have lots of leftover cabinet grade plywood so they should look nice if I put in the effort.
