Nice improvement. If you could also get it to flare vertically, that may improve the sound quality.

[@RickMcQuay]

+John Heisz I have drawn a design that flares in 3 directions but haven't built it.

[@BlueOceanDesigns]

You should continue this quest....Would love to hear/see the more perfect sounding design you can come up with. Keep it up :)

[@RickMcQuay]

Thank you. I have plans for more variations that should be louder still but am waiting until I buy a new phone.
