I get that this site is dominated by engineer types who seek perfection but sometimes the goal is improvement as opposed to perfection. What with a limited budget and available components.
My first argument was that, for the money, commercial manufacturers can build better cabinets than diy'rs.. So I purchased a JVC home theatre 19 litre sub for $7. My initial plan was to replace the 6.5-inch driver with an 8-inch driver obtained from a Tannoy sub with a dead plate amp (cost $15). However, I sold the spike feet on the Tannoy for $10 and the driver for $25 because the location of the port on the JVC would make fitting an 8-inch driver tricky.
The 150w JVC sub sounds nice, smooth and sweet but the problem was always going to be: SPL 77db / 30Hz / 6 ohms. After a debate with Chris661 and Weltersys they intimated that substantial increases in SPL could be obtained by an increase in diaphragm area.
Using only the components I have lying around this is the upgrade:
Don't you think this is a fun waste of $7?

Must be something about Tannoy subs and falied plate amps. I bought such a beast, added a twin chip TPA3118 2.1 amp board, some Eltax satellites, an RPi running Moode for a simple outdoor system, running off a DeWalt 18v 5Ah battery.
