Hello!
I'm looking for some advice on building four 8" roof mounted full range speakers. I want to create speakers that are stylish, compact and powerful!
They are to be used as DJ booth monitors or maybe, depending on the sound quality, in a small cafe. I'll start with these but will be adding a subwoofer later on.
Recently found 4pcs 8" drivers from Celestion RS1 mk2 and the Celestion SRC1 mk2 limiter/dsp that goes with the original speakers.
The drivers are called T4579 but I can't find much info on them other than that they are quite impressive full range drivers rated at 8 ohm with a power handling of 175W and a sensitivity of 99db. I believe they would be up for the job as booth monitors together with my full size club system.
The original SR1 enclosure for two of these drivers, is approx 30litres with two maybe 2,5" diameter ports.
Then there is the half size 15litre SR3 enclosure for one driver and this is the one closest to what I want to build.
Here's an article about the original speakers: https://www.muzines.co.uk/articles/celestion-sr1-sr3-monitor-system/459
I want my speakers to be unique so instead of a rectangular box I've been looking into creating a drop shaped enclosure.
As I've come to learn, a cylinder is the worst for diffraction, and a sphere is the best. So how do you think a drop shape would work out? Of course the inner chamber can be of a different shape than the outside of the enclosure.
The enclosure would be made out of plywood rings, glued together and then machined on a lathe where the max diameter is 36cm. This could make for a beautiful roof mounted design piece to put in the corners of the room or 2 by 2 in front of the DJ booth.
Ideally I'd like to make it a vented enclosure just like the SR3 but I'm unsure about the calculations. Volume, shape and port length.
At the moment I only have access to Mac computers so can't use WinISD or Hornresp.
Any pointers what to think about when designing this? Ideas?

Went ahead and made these based on assumptions, copying the volume and port size of the original enclosures! What do you think?
Still need to find the right tool for cutting the metal bowl! Figured I'd just mount it in my lathe and cut. Still haven't decided on how to make the port of the egg.
