The Premier Mounts UNI-EFTP-AUD combines the universal Fine-Tune Projector (FTP) mount with a universal short-throw projector wall mount and powerful stereo audio system. It can extend up to 67 in. from the wall when used with the included arm extension and mounts to dual studs at 16, 18 or 24" spacing. It does not require a stud in the center of the whiteboard/screen. The included Compact Power Amplifier (CPA-50) powers the speakers and supports multiple stereo inputs, which make it perfect for connecting to a projector, microphone and other sound sources.
