Hi all:
I have a requirement for a midrange, 300 - 4000Hz drive at around 50W RMS max. Tenor Steel pan amplification.
The flat diagonal of the box rear panel should not exceed 12" as it must fit inside a 12" cylinder. I am hoping for perhaps something in the 8 x8 x8" range as the max dimensions.
The spkr 'box' can be a cylinder as well.
I am looking for a guide to design such a box. Sealed seems the most forgiving.
I guess the driver might be around 4 - 5" but I am open to suggestions.
I still have to get the driver.
Scrapped an Aiwa mini stereo today, but got a 6.5" woofer and a 2" Mid and a tiny tweeter out of a reflex enclosure. Thought I could reuse the woofer and midrange in a smaller sealed box enclosure as I don't need the low end of the bass. Not sure how to size the box volume though...as I am NOT trying for bass here.
this calculator:

Needs data I don't understand, if someone can explain those parameters (and where to find em) I would appreciate it.
Interestingly there is a sample for a 4" spkr on this page:
https://www.diyaudioandvideo.com/Tutorial/SpeakerBox/
that comes up with a .77 litre volume. If that's a decent ballpark I can work with that.
Also, I am wondering if 4" PVC waste pipe (true dia. = 4.5" ) could be made into a housing by endcapping one end and mounting the spkr in the other. The waste pipe can be made malleable with a heat gun to 'suit' the speaker fit.
thx much
