## Questions & Answers

**Q: What are the length and height dimensions of the soundbar? How many watts is the soundbar and subwoofer?**
A: The wattage of the sound bar is 40 watts.  The subwoofer is also 40 watts!  That’s 40 watts each!  This is a very nice sounding sound bar!  The room the sound bar is in is 28 feet by 28 feet!  If your not happy with this sound bar, you don’t need a sound bar.  You need a sound system like I replaced with this bar.  My old sound system would shake the house and rattle the windows with 150 watts of awesomeness !  I now have hearing lose from all of the loudspeakers.  It may be impressive to shake the house, but believe me, it’s not worth your hearing.  My wife and kids are always getting mad because of having to repeat themselves so often.  I can hear fine.  I just wish everyone would talk louder! 😂  I was a sound man in a Art Center for over 15 years before retiring.  The hearing specialist said I need a pair of 5,000 dollar hearing aids.

**Q: Does it come with the arc hdmi cable?**
A: The HDMI cables I purchased clearly say they support HDCP 2.2 & 2.3, Enhanced Audio Return Channel (eARC) Dolby Atmos Vision and Hot Plugging.
My advice is look for a cable that has at least a 8K @ 60Hz refresh rate. 7680x4320 ultra HD resolution, compatible with 4K@120Hz and 2K@ 240Hz
I use a much more powerful sound bar but this applies to any TV that has a dedicated eARC port

**Q: What size is the subwoofer speaker**
A: Did anyone actually read his question? he asked the size of the subwoofer SPEAKER...It's 5.25" tiny little guy you aren't gonna get much bass

**Q: Will it work well with a samsung tv? or is it better to use a samsung sound bar?**
A: I have an older Samsung 56in TV built in 2009 (doesn't have a dARC connector) I have it attached with the optic fiber. It works great, but I do use the Polk remote to turn the sound on and off and adjust volume. I was using a Samsung soundbar and subwoofer, but Polk provides a vastly improved sound. And I don't have to continually adjust the volume to hear the dialog like I used to do with the Samsung sound bar.
