DIY Phil Jones double four

[Faniel]

Well I was researching small practice amps and came across the Phil jones double four. It looks pretty sweet but too pricy for me right now. I decided to try to build my own version while buying as few materials as possible. I built it using 1/2in ply I had left over

and speakers off amazon.

I wired them in series to get 8ohms. If I did it again I would use a small amp off amazon like this.

And use one of those VOX headphone amps as a pre. I did it this way because I had an old amp that had been sitting around forever.
I don’t have it ported yet but it hits the low B pretty well for me and I’m happy with it. I still need to clean it up, sand and paint.

That amp linked is for sub. Output 20-180hz.

its the phil jones rampage.

power cord hanging out is best part

sweet

I doubt its much like the PJB, which has some pretty sophisticated sound engineering, but if the result works for you then thats great. If you are happy with the low end I'd not add ports as there are some definite trip ups in that area.

The only similarity this shares with anything PJB is in the diameter of the drivers. I'm not saying it isn't a fun and interesting project, just that I'm somewhat surprised that none of the acolytes of that camp have spoken up to register their objections to the comparison. I'm with @JimChjones in saying that if it works well enough for you, then it's all good and it wouldn't be worth the effort to try to port it.

We Acolytes Of Phil (AOP) are a kindly bunch. The execution will be swift and merciful.

I had meant to link this amplifier board.

I prettied it up a little today and added feet and a handle.

I've never used this board, but recently got a couple of stereo amplifier boards with BlueTooth. I've noticed that with these boards, you can look up the chip and learn a lot about it from the manufacturer's datasheet. I'm guessing that the design of the board doesn't stray very far from the typical recommended application circuit in the datasheet.

Best of luck with the project!
