Default ikea bowl speaker + CHR-70 gen.3

I decided to make these funky spherical speakers on a whim while hacking the pogoplug into a network wireless music player. I discovered the diyaudio.com forums while looking for a USB soundcard and ended up with a Topping TP30.

It didn't take me long to come across the posts on using ikea wooden "salad" bowls to make a set of unique speakers. There weren't any detailed plans but the forums had plenty of ideas. Also, I decided to use the CHR-70 gen.3 drivers after finding out about them here too.

I posted regularly on Google Plus as a semi worklog. If you're interested, you can find the relevant posts here, DIY Spherical Speaker Project @Google+ Sort by "Most Recent" to view them in chronological order. Now, I just have to decide where these are going and make some stands for them!

Thanks guys! It was great fun building them!

I'm just running them in at low volume atm as Mark suggested I do with the new drivers. They sound very good so far!! However, with them being sealed I get the impression that the bass maybe a bit lacking but it's hard to tell right at the moment.

Hi Martin,
Yes, sealed is going to be a limiting factor for the bass. Might be well worth adding a port.
Cheers
Mark.

Hi Mark,

Thanks for the advice! I think I'll probably end up porting it but I think I will enjoy it as is for a little while before doing so.

On a side note, I was talking to a colleague and he said he's willing to part with a Yamaha DSP-A2 at a very favourable price and I was thinking would this make a better accompaniment to these speakers?
