Q I’ve heard that sealed subwoofers sound better than ported ones with music, but that ported subs handle LFE in movie soundtracks better. I want a sub that will sound good in my large, open living room with both music and movies. Do people only use sealed subs in smaller rooms? How will a ported model sound different when playing music?—Matt Carlton
Q I don't have room for a surround setup in my home theater, so I’ve decided to buy a pair of floorstanding tower speakers. My TV has a super-wide viewing angle. Are there any speakers with a super-wide listening angle? I don't want to be the only person in my family sitting in the "sweet spot.” —Edward G. Jones
Q I am switching over from a 5.1 speaker system to a soundbar but would still like to use my current Paradigm PW 2500 subwoofer with it. Are there any new soundbars that can be used with an existing powered sub? —John Rothery / Tacoma, WA
Q I hope you can help me. I am old school: born in the early 60s, rocked out in the 1970s. I had a nice JVC stereo receiver that I bought in 1985, but it died after a couple of resistors got fried. What can I buy to replace it? I would like to play my vinyl records so I need a phono input. I also have a nice Onkyo Cassette Tape deck and a Technics Compact Disc player I want to use (both with the old red and white jacks). Plus I have four speakers that use copper wire to clip to the back of the receiver. Major volume potential is a requirement as I need to crank my 1970s rock! I don’t want to break the bank doing it, either. —Scott Wellington, Marietta, GA
Both Sony and LG had 84-inch edge-lit LCD TVs on display at CEDIA. What distinguishes these sets from other oversized TVs from companies like Sharp, etc. is that they have a resolution of 4K (actually, 3,840 x 2,160, or “Quad Full” HD).
