Bogen SM4T Reviews

Disappointed in the misleading way B&H handled my order

I am a big supporter of B&H and their very responsive service. I needed eight(8) ceiling speakers with matching transformers. Most websites will advise what quantum is available in their inventory. B&H did not giving the impression that all eight will be shipped in one go. It was shipped in three shipments resulting in shipping and associated cost being twice the cost of the speakers.

These are the easiest speakers to install in a drop ceiling and they look great!!! They can be used on a 25v or 70v amplifier and the audio output adjustments are switchable. Great product for the money!!!
