Laser TVs typically have some decent speakers built-in. Consider: None of these 4K UHT projectors are going to compete in sound quality, bass, etc., with a good $500 stereo surround sound system nevermind serious home theater. . The better Laser TVs, like the VAVA, are easily capable of room-filling sound, even if lacking serious low bass and the special qualities of a better system.
HK - Harmon Kardon, is a great “cut-above” brand, I’ve owned some of their audio gear going back to the ‘70s. Now their speaker systems are found in projectors, luxury car audio systems, etc. This configuration sounds pretty darn good, compared to say, most TV’s soundbars. VAVA says the HK's are 30 watts a channel, which suprised me because most of what's in Laser TVs is 10 watts per channel.
With that said, I spent the first week with the VAVA in one location (summer rental), where I had the audio hooked up to a good AV receiver and some moderately expensive speakers and a subwoofer. No, when I switched back to the VAVA's internal audio, it was no match, of course.
But it did fill a pretty large room with well balanced sound (no tinniness...). It's got more than enough muscle for your favorite action flicks, even if it won't shake the foundations of your house.
