I love the Tiki V2 trumpets, they remind me of the hoots from the Clangers.

Ok ok, you inspired me quite a lot. I like Tiky and Wicker Pods, I think it could be really nice made of rattan.

Well I had this shaped digi-flower for some time in my head. I was thinking about making some kind of new digi-flora that could adapt on normal nature.
I was also thinkig that maybe such kind of formable stem could be used for Tiki 2…

I’m really feeling the tiki, that looks like it could be a lot of fun. Its great that its modular too so you could go from stereo to full on surround.

i love the tiki’s.

The ideas are interesting, but if you want to create outdoor speakers you should also take into account the acoustics of the object holding or projecting the sound. The images showing “horn” shapes on the front will be very difficult to work with, reduce dispersion (the ability to cover large areas) and if not properly designed cause the music to sound as if it is coming from a can. Hero’s columns that can be stuck in the ground offer the best acoustic possibilities, especially if you smooth off some of the corners and add a rounded shape to the back. Most other designs I have seen here would have to trade significant sound quality for design; in other words the engineer would have to say, “we are marketing the look so it is okay if the sound is somewhat compromised”. This last is not unusual, and every speaker in the market place I am aware of makes this compromise somewhere in the design. Check out the BMW Nautilus for the speaker that makes the fewest (again that I know of) compromises and still achieves a unique and interesting shape. I am sure however that you were searching for designs that anyone could afford.
One last thought: As to the use of photovoltaic cells, you will have to allow for significant area (maybe 4ft. x 4ft.) to achieve enough electricity to power the speakers which will also need to contain an onboard amplifier. Alternatively you could use a smaller cell and large battery but expect it to take many hours to charge. Of course a battery would be necessary in any case if you intended to use it at night. Take into account these criteria and I would be very interested in seeing your designs.
