Questions

JUST BOUGHT THE MAGNIFI MAX AX SR SYSTEM FOR INSIDE MY HOUSE FOR THE TV. IF I WERE TO BUY YOUR ATRIUM 4 OUTDOOR SPEAKERS, CAN THEY "CONNECT" TO THE INDDOR EQUIPMENT & WORK ? OR DO I NEED TO BUY SOMETHING SEPARATE FOR THEM TO WORK ?

Asked by: SHADY DALE
Hello, the MagniFi Max SR is a standalone system that will not connect to other speakers such as passive speakers like the Atrium 4. The Atrium 4 speakers will require a standalone amp or receiver to power them. We would recommend using Denon or Marantz products to power these speakers as we find they pair very well with our speakers.

If I want them to be bluetooth compatible, what is the recommended amplifier to connect these speakers to?

Asked by: blakemartin552
Hello, For Bluetooth the be in the mix with the Atrium 4's as your speakjer of choice, you will need either an amplifier or receiver with Bluetooth already built-in (Denon's DRA-800H or Marantz' NR1200 are a good example), or an external Bluetotth receiver can be bought and added to any integrated amplifier or receiver (such as Denon's PMA-600NE.

Can these be put in the ground and withstand rain and snow?

Asked by: Tim tool
The Atrium 4 speakers are not designed to be placed in the ground. Some coverage is recommended, mounted under the eaves of your home if possible.

I'm the owner of a inflatable nightclub business and like add music to my services offered. My nightclubs are 20"by 20" will these speakers offer enough sound to fill this amount area?

Asked by: Cloud9 nightclubs
Commercial speakers might be a better solution depending on your overall needs, volume levels, installation, and mic use. Commercial speakers offer 70v taps, allowing the speakers to be installed in series. Otherwise, two to three pairs of Polk Audio Atrium 4 may be all you need for simple background music at moderate volume levels. Be sure to use a standard AV receiver or amplifier with the Atrium 4 speakers.
