While the built-in dual 1-watt speakers may suffice for a presentation to a small group, there is a Bluetooth audio capability for driving external speakers for larger gatherings. The fan noise from the PF50KA is very low, even at maximum brightness. The LG PF50KA has a very small footprint (6.7" x 6.7" x 1.9"), and at only 2.2 lbs it is ideal for portable home theater and video in any area where you can turn the lights off, either indoors or for back yard movie nights.
