Very good sound but poor look up front. Tentec could have use plastic grill up front instead of material, I think that is obsolite.

Hands down this is the nicest speaker.It has a rich full sound.I have owned speakers from the big three manufacturers as well as various bookshelf and computer speakers and none of them come close to the sound quality of the 307 speaker. The build quality and appearance of this speaker is second to none. Ten Tec's customer service is outstanding! Ten Tec has another new customer

I had been looking for an external speaker to use with my Elecraft K3 transceiver. Finding a good 4 ohm speaker does not seem to be an easy task and Elecraft refuses to build one for their product. Thanks to TenTec I now have excellent audio from my rig. It is a great product and I am very satisfied with it. In me, TenTec has a new customer. Thank you.

Very impressed and pleased with the looks and the performance of the 307B speaker. Very tough build and nice quality sound, and let's not forget the affordable price that comes with it.
