China sealed full range speaker design

Teardrop. A la Hershey's Kiss, or a kind-of heart shape rotated about its central axis.
The mounting depth can vary: sunken in for a wave-guide effect, or flush.

The 'point' at the rear is intended to guide the diffracting sound waves backwards, so they don't converge onto themselves as with a sphere. To determine an 'optimal' shape would probably require simulation and testing, but I think some very nice approximate shapes could be made by hand.

As for building... How good are your artistic skills?
I only built birch plywood rectangular boxes(FAST in picture and I liked sound a lot). I think I can find huge surprise egg toys (30cm) and they may be suitable if I enforce inside) Regards

What about putting a mixture in a raindrop balloon and turning it to cover inside of balloon and then after it dries we can get a nice shape and easy to make enclosure. I watched someone make a surprise egg with cement but I think cement is not a good idea because of it may resonate. Which mixturr materials can I use?
 
I just had an idea: what about a tic-tac shape? Shouldn't be too difficult to make. Two Ikea bowls connected by a short (15 cm lenghth or so) PVC pipe.
So it wouldn't be a sphere. Wouldn't be a pipe either. Nor a teardrop. Still, why not? 🙂

When connecting 20cm IKEA bowls together it already needs a bridge circle to make a perfect sphere because it's height is a bit short.(About 9cm height) But I think tic tac shape may cause resonances because of it will have parallel walls ( we do not want parallel walls because of modal resonances ) However maybe noone can hear this because we will already make stuffing inside the box and they will be eliminated. Here experts will answer better imho Regards
 
I finally cut the boards.But not glued yet. Inside dimensions 203x165x132mm and MDF thickness 19mm.
But I couldn't decide which side to put the driver,wide side or narrow side?. And which position to put the driver. As I remember 1/3 of the side is good but chstgpt tells to put driver in center of the panel

I finally completed the assembly and glued the boxes, and I’m really satisfied with the sound quality! Initially, I tested them using a Muse TA2020 amp, but the output felt a bit underwhelming in terms of power. After switching to a Quad 405 clone amplifier, the difference was remarkable—the sound became much more dynamic and impactful.

In comparison to my older Aiyama speakers, I find the bass response in this setup slightly weaker. However, it’s worth noting that the Aiyama enclosures had about 15% more internal volume. That said, since these boxes are designed to work with a woofer in a 2-way configuration, the lack of deep bass isn’t a major concern for me.

Interestingly, I’ve also planned to use these speakers in full-range mode for specific types of music, such as instrumental tracks, where imaging and clarity are more critical than bass depth. I’m excited about the versatility this setup offers—both as part of a multi-way system and as a standalone full-range solution.
