We're about to find out with a review that's coming in a couple of weeks. In the meantime, you might want to check out the Tutti Matti Kickstarter page, where the company is offering the new speaker for prices less than 1/2 its $299 list price.
It's hard to distinguish a new Bluetooth speaker in a crowded market, but Tutti wants you know that their small (6" x 6" x 4 3/4") speakers are really loud and come with a "Liquid Dance Floor" feature that allows you to link together up to 8 speakers by pressing a button on top of the speaker.
Tutti has enlisted LA street dancers to endorse the speaker, since they're going to care about volume when performing for tips on a street corner.
It also comes with a microphone, so you can be your own hype man at your next party. Check back soon for a full review.
