Speaker Enclosure Size – Effect on Audio Quality

KEF LS50s or Goldenear Triton Sevens for multi-channel use

Does a speaker’s enclosure size have any effect on audio quality? I've always assumed a larger enclosure size is better, but I never understood why that is the case.

Moving Magnet vs Moving Coil

I bought a new turntable but am still trying to decide on the cartridge. Should I get a moving magnet (MM) or moving coil (MC) cartridge? What price range should I consider assuming I have mid-priced components in my audio system?

Speakers with No Box Enclosure

Speakers with No Box Enclosure

I heard some speakers at a local HiFi show and they were mounted on a single board with no box enclosure, so you could look behind the board and see all of the speakers, wiring, and cross over network. What is supposed to be the desired effect of mounting them this way?

Speaker Cone Material: Best Performance?

Speaker Cone Material: Best Performance?

Speaker cones seem to be made out of a lot of different materials. Hasn’t some particular material emerged as the best to be used or is it just the manufacturers want to have something unique to their own speakers?

Will The 4K TV I Buy Today Become Obsolete?

Will The 4K TV I Buy Today Become Obsolete

Most TV stores have Ultra-HD (4K) sets for sale. Are the specifications established, so we can buy one without worrying that it won’t work if the final specifications are not part of the circuitry in the 4K TVs being sold right now?

Are power ratings of A/V receivers directly comparable?

Are power ratings of A/V receivers directly comparable?

I saw two receivers that I am interested in…both of them were specified as having 100 watts x 5 in the power amps. One receiver was priced at $699, the other at $1499. What might I expect the differences to be when the specification were the same?

UltraHD: Can we see the benefits

There seems to be some confusion as to whether the UHD resolution will be observable with screens 65 and under from realistic viewing distances due to human eye limitations. Is this true? Will the REC. 2020 wider color gamut have a greater impact on the average home viewer?

DTS Master Audio: Question About Output Formats

DTS Master Audio: Question About Output Formats

Need help understanding DTS Master Audio. I have a Samsung BD-F5900 Blu-ray player attached to a Yamaha RX-V475 via HDMI. I have the audio on the Blu-ray player set to output unprocessed bitstream but when I play a movie, the receiver only displays DTS and not DTS MA. Is this because the receiver is only 5.1 channel and am I really getting the full lossless audio provided by DTS MA? Aside from the extra channel audio, should I set the player to output PCM and will I be getting higher audio by setting it to PCM?

Connecting Internet to PC to AVR to TV

Connecting Internet to PC to AVR to TV

I, rather my wife, would like to view internet offerings on our home theater system, particularly the larger screen. I can find any number of articles on the physical connection to PCs/laptops (directly) to a TV but find little or nothing even in the AVR manuals on how to make physical connections to an AVR as well as what setup of the computer, AVR and TV...

Low-Profile Speakers for the Audiophile in Challenging Space?

Low-Profile Speakers for the Audiophile in Challenging Space?

I am somewhat spaced constrained and am looking for speakers (5-10K range) that are relatively low profile and, more importantly, are designed to be placed up against the wall. Many of the speakers I have sampled require a placement at least 12-18" from the wall. The room is approx.: 14 x 21. Ideally the speakers would be placed on the 21' wall. In wall speakers are not a good option (old plaster & lathe walls on 2/4 studs). I am looking for a 2 channel audiophile solution to replace an older system. Our listening preference is primarily classical (symphonic) and jazz with the occasional R&R. Generally prefer imaging over brightness.

Black and White Movies: How to Calibrate

Black and White Movies: How to Calibrate

I have a KURO display that has the ISF-Night mode calibrated to 30 foot-Lamberts with a 6500 K white point. I also had the Pure mode calibrated with a 5400 K white point for black and white movies. Should I use the 5400 K calibrated Pure mode with black and white movies on Blu-ray? I have always wondered which is the most accurate white point for black and white movies. Do they always correct the white point of black and white movies so that it looks correct on displays calibrated with a 6500 K white point?

Which AVR Should I Choose: Anthem 710 or Pioneer SC-79?

AV Receiver (AVR) Choice: Anthem 710 or Pioneer SC-79

My dream of owning a Statement ended when I woke up realizing it wasn't going to happen. So, now I have narrowed my choice of AVR down to two. It's between a Pioneer SC-79 or the Anthem 710. Which would you recommend I go with. I would be looking for whichever one to be able to handle a medium to large size room. Bells and whistles don't mean a whole lot just the sound. I'm not a big music guy so most of its use would be for gaming and movies. I currently own the VSX-84txsi and have enjoyed it for seven years, but the 710 is very interesting to me (not to mention the fact, it's a thousand dollars cheaper). Any advice you can give me would be greatly appreciated and please keep up the good work. Thanks SECRETS!

Power Protection: Fancy Power Protector or UPS or Simple Surge Protector?

Power Protection: Fancy Power Protector or UPS or Simple Surge Protector?

I just bought a Samsung UN65F8000 LED TV, a Piooneer VSX-1128-K receiver which will power a pair of polk audio RTiA1's a CSiA4 Centre and PSW10 Sub. Also in the setup is HD Satellite box, a PS3 and a PS4 when it arrives in three weeks along with a BoxeeBox and some other crap. My question is about power protection. Should I get a fancy power protector for several hundred dollars, a UPS or simple surge protector? I don't mind spending a few hundred bucks if it will serve a purpose. Our power isn't bad but goes out acouple times a year and we get a brown-out now and again.
