Well that's the beauty of designing with ceramic garden pots!! If the sound sucks, you can always harvest tomatoes. How many of you woodie box DIY'ers can do that (without rot)? (On the other hand, you could make some damn fine pet coffins). (':lol:')
On the other hand, extremely low resonance, and an inverted horn design might just make a trip to the garden center worthwhile. I paid less than $40 for the pair of 25 litre pots. I'm always looking for better ones, which more closely resemble the nOrh drums or the B&W nautilus.
The prototype is finished using Onkyo D-202A (well-reviewed in it's day) drivers/crossover and I would say the sound has improved immensely. Not just more efficient (louder) but with much more detail, though still lacking in lows (not surprisingly as I have yet to properly tune the box). Maybe I just got lucky. [/img]
