Rockville CT80 8" 50W 70V Commercial Subwoofer, Wall-Mount Bracket, Deep Bass, Wide Frequency, Durable Build, for Restaurants and Conference Rooms

It has great bass for the money. Goes perfect with our stereo

We liked the sound and performance

You will not get any appreciable level from this subwoofer. In fact, when put it next to a single OSD AP520T outdoor speaker, you will barely notice any additional bass. Sending this one back. Given that it is almost impossible to find a 70V subwoofer, I assume there is a reason. Going to try a standard subwoofer and drive it using the 4-8 ohm output on my 70V amp.

These subwoofers are easy to get up and going. I wall-mounted two of these in our work meeting space ( a rather large room without ceilings in a shop). The wall-mount hardware did not line up completely with the threaded serts on the back of the subwoofer so I had to slightly coax one of the brackets to fit. These add a much fuller sound to our speaker system, though they do chuff some when driven harder. It is not a deep bass, but enough to add some oomph to what would have been an anemic sound system. There was an issue with one of my subwoofers where there was a sound coming from the port akin to a whistle or vibration. I found that the plastic inserts in the ports are not very well insulated and air was passing AROUND the plastic port insert, causing the whistling. I gently pulled the port out and added a little caulking around it and re-inserted it. After everything dried, nothing was visible and the whistle was gone. Despite these issues, I would recommend these subwoofers if you are looking for fuller sound without wanting to have a thumping party.

Not great sound quality is OK, and it is not very loud and cheep stuff as usual from Rockville. Think cheep IKEA, but for sound. 8 x 10 room it will be OK, anything bigger it wont work.

I was going to return it but I tweaked my amplifier, put it in the corner near my wall, and turned it up. It's much better on the bass and treble. It's not real for a home theater system. Although I am in aptmante so it doesn't need to be super loud.

Funciona con un subwoffer bajo pero profundo mejora el sonido del equipo. Creo que para mi instalación ocupo 2 más. El soporte es excelente. Y da un buen sonido

Good quality good material but it's not a sub woofer it's a midrange, im pro rockville but this item no work to me, so return I'm sorry
