4W 28mm WOWSpeaker

I've had this speaker in a special project for several months now, mounted in a wood resonance chamber and it sounds incredible with a CFX. Not sure why everyone else is having issues but I wonder if perhaps they aren't mounting the speakers correctly. You see a lot of glue in designs in chassis for whatever reason where the speaker isn't braced or supported from the front. And with bass type speakers that have a large amount of travel in the diaphragm, suspension, and spider. There isn't much to keep the speaker from vibrating itself apart. You need to support the front of the speaker somehow, a ring or gasket or hot glue of some kind, or do a press in mount instead of a drop in mount. There is nothing wrong with speaker, just how people are using it is wrong. Note: as a rule of thumb a 4ohm (higher draw) is going to pull more juice from your battery than a 8ohm. So you will notice distortion when the battery drops low. With direct draw style 3.7V boards this is common.

I wired this speaker for the CF-X which defaults to the 100% volume from R.I.C.E settings, and I'd say after the second day of intermittent use while tuning it next to the computer, it suddenly went silent. I bought it a few months back and used it briefly in a different build with an NEC board, so it had a couple more hours on it I suppose. I pulled it from the hilt and used a meter to check ohm resistance and it's a door stop. Do not buy this speaker, really disappointed it lasted only a very short time. It's rated for 8 ohms so the volume set at 100% shouldn't have phased it a bit, compared to the 4 ohm premium speaker set at 75% recommendation.

I love this speaker. It is LOUD and sounds great. I use 31mm speakers as well and this keeps up with those no problem! Pair this with a Proffieboard, give the volume a boost in your config, and you can make some serious sound!
