Calling all audiophiles

[Dose Pipe Sutututu]

Got bored took photos of the sub I made. Original enclosure had 2x 10" Peerless drivers in an Isobaric configuration. 

Although sounding nice, wasn't good for movies so I took both drivers out and sold them and replaced it with a single Dayton 10" HF series driver. The front baffled needed to be enlarged to fit the driver (something I didn't account for lol).

Then of course the original 150W RMS Jaycar plate amps wasn't up to scratch and the driver would clip/bottom out, so an O-Audio 500W RMS plate amp was fitted.

A year later, got bored and wanted more output, used WinISD and calculated I would get about -3dB roll of at about 21Hz with a 4" port and I think about 30cm long or so. Has been like that for over a decade, until a few months ago the amp would randomly hum as though I've taken out the RCA out and earth it against the chassis of the amp.

Tested with another sub (Focal Dome, now sold) and RCA nor receiver were the issues. Concluded plate amp is fked.

Took the grill off for a photo.
