The ones from TIC were... Ahem. right up their with a Public school in the big city for S.Q. Nothing to write home about. They were muddy even before they were muddy. I often give products a LARGE leeway. If I don't care for them? Imagine how bad they really sound to anyone with a trained ear or standards.
They sound OKAY if elevated, E.Q'ed, and at listening height from a distance or you were laying on the grass. But not much else.
JBL has a nice omni speaker. But its not really... It just works as one. Its the waveguide I think that does the magic. $450 bucks, but it's going to stand the test of time. Look for them used as plenty of shops have closed and they should be tons on the used market as they get ripped from existing installations and can be picked up for less than $100 a pair/
The JBL Control series is not built like cheap plastic outdoor speakers where they feel every bit as plasticky as they sound.
I'm not sure Omni is he way to go for most residential sound applications where you have neighbors, sheds, etc. Directional seems to tbe the way for most home applications and settings. just like a room for speakers makes or breaks them. There is some thought about that in the outdoor senario.
Not sure if there are any books out there about outdoor speaker placement written in the last few years. Amir should publish one. It would be worth reading and not make you fall asleep while doing it. Check out his speakers install he did at the Seattle ferris wheel. He goes over the basics in the article he published for a periodical. And gives some pointers about types of speakers that work best, and placement to a degree.
I forgot the name of the tech, but its also made by JBL, and works on the basis that it does not have a hot spot so to speak.
If you want to do something custom LF wise? I made some subwoofers out of these
Put a fake plant on top, and they blend in anywhere. Most have provisions for holes on the bottom to run the wire to them with some silcone to seal the plug on the bottom. Hide the wire under the rug as shown, or through the deck slats. Use large frame plastic plants so they don't move or vibrate leaves, and your set. All for less then a hundy, you got a good LF source that blends in anywhere. Easy to build, and handles the elements quite well.
Some DML speakers seem to work pretty well. Dayton has some outdoor rated models. Not Omnidirectional really. But you can mount them anywhere and hide or cover them up to blend in with any outdoor decor.
Omnidirectional sounds good on paper, but the application of it is IMO, a bit more troublesome then at first realized.
Say for instance here:
Or here:
The ones you should stay away from are the ones that bounce sound upwards if in a covered patio area. That was from the JBL Contractor / Rep that we spoke with when doing the installs for Comtech.
