Well here is an update if anyone cares.
I decided to start small and see how these cheap 5.25” 3 way Pyle speakers sound in a homemade enclosure with my current amp. I was originally thinking I would need up to 8 speakers but I started with 4 to see how they sound.
After some experimenting I ended up I making the Boxes out of PVC board as a sealed enclosure. All the seams are glued and calked. The speakers are sealed with a bead of plumbers putty. Since the speakers are 4 ohm I wired them in series on a single channel, alternating left and right, to bring the impedance up to 8 ohms and allow for LR sound in the front and back of the yard.
The amp seems to be happy and the sound ain’t half bad but I’m no audiophile, just a Metalhead.
I placed one in each corner of the yard, two by the pool and two by the patio. They sound great loud but I can also hear them on low from anywhere in the yard which was the goal and Since they are low to the groun, (2 feet) I hardly hear them from my front yard. They are now painted black and mounted on 2”pvc post.
Since my old receiver took a dump, likely from all the dust I make in my garage building stuff, I decided to make a positive pressure cabinet for my components as well. I used a 120v computer fan I had laying around and some scrap plywood and plexiglass. A little body filler and some paint and she’s ready to thump.
Last thing is to build a permanent outdoor subwoofer. Ive been using a sealed box 10” from my old car stereo days but that’s not going to cut it for long, way too inefficient. I’m thinking I’ll end up building a 4th order bandpass with a 10 or 12” driver. I picked up an amp that can push it so all that is left to do is pick a driver and build an enclosure. I’m figuring the PVC board should do a fine job again but I’ve got many details to work out there.
