    Do bits matter for CD playback?

    I'm in the market for a new CD player and am a little perplexed by the XX-bit specification. I noticed that some 18-bit players are more expensive than some 20-bit and 24-bit players. Choosing among 18, 20, and 24-bit players, is this something I need to concern myself with? Or does it not...

    Paradigm Cinema 110 CT dealer pricing concern

    A friend recently purchased the Cinema 110 CT package. The MSRP for the set is $800. The dealer knocked off a whopping $10, claiming that the package is already pre-discounted from Paradigm. Does that sound right? I always thought that 10% off was the bare minimum. I actually feel bad for having...

    Automatic watches

    I know there are quite a few timepiece aficionados on HTF, so I thought I might inquire a bit about automatic watches. I have used battery-powered quartz watches for most of my life. Instead of changing batteries, I tend to abandon watches after the battery dies. This allows me to change...

    Revel Concerta

    There is a press release on the Revel website dated in January. Secrets had a small article at the end of March. No mention of when the speakers might be available. I contacted the nearest Revel dealer in a nearby state, but it seems my business is not needed (or the Concerta line is too cheap)...

    Best SVS to give as a gift?

    A friend is purchasing a condo soon and I would like to get him an SVS as a little house-warming gift. He has never had a home theater system and I would like to get him off to a good start. The two models I am currently considering are the PB10-ISD($430) and PB12-ISD($600). I like the price...

    Are there any portable DVD players that use regular batteries?

    I'm flying to Australia soon, and I've been told that it takes around 24 hours or so. I was thinking it might be a good opportunity to catch up on some DVDs. Problem is, the battery packs that most portable DVD players come with last about 3 hours then need to be recharged. Are there any players...

    Can subwoofers damage VHS tapes?

    I put my 25-31PC+ behind the TV, which sits on a stand. The stand has a few side shelves, where old video tapes are stored. I have removed the VHS tapes for the time being. Can they be damaged (erased or degraded) by the sub? The shelves are 2-3 feet away from the driver. The CRT TV shows no...

    I am having tremendous difficulty deciding between the Ascend Acoustics CBM-170 and the B&W 705. Any input would be greatly appreciated. My Application Extreme nearfield use. I need speakers that I can listen to while I am working at my desk. Unfortunately, the desk is pretty much up against...

    $1 per watt, good deal?

    Say I could get a used, well-regarded current-model multichannel amplifier at a price where the price/power ratio is $1/watt. Would that be considered a pretty good deal?

    Any wait to get rid of paint stains?

    My favorite sweater and backpack accidentally got tagged with white paint today. Are they permanently ruined, or is there a way to remove the paint? I'm thinking about simply trying paint thinner, but I'm not sure it will work... And just in case someone happens to know, the paint was being...

    Why are Yamaha receivers considered bright?

    I just read a recent review of a Yamaha RX-V640 at http://www.hometheaterhifi.com/volum...3-part-1.html. The receiver was described as bright, which would seem to imply exaggerated top-end response. However, the frequency response graphs shown for the amplifier were pretty much ruler flat. So...

    Non-defeatable plate amp low-pass filter and receiver crossover

    Say I have a subwoofer with a plate amplifier. The low-pass filter is continuously variable from 50-150Hz, but cannot be bypassed. My receiver has its own 2nd order low-pass filter, which I would like to use. What would happen if I just turned the plate amp filter all the way up to 150Hz and set...

    Progressive DVD player with non-HDTV

    I plan on purchasing a widescreen TV within a day or two. I have a progressive scan DVD player that I have used with an HDTV RPTV in the past with excellent results. However, I have never tried using the DVD player in non-progressive-scan mode. Assuming a TV has component inputs but is not an...

    LCD monitors and unshielded speakers

    Just curious, are LCD monitors susceptible to magnetic interference from unshielded speakers? I'm hoping to use Dayton BR-1s as computer speakers.

    What is the protocol for trades?

    I've always sold my DVDs on eBay, but trading might seem like a better idea. Could someone please give me some information regarding how a trade is done?

    Any amps with anti-clip circuitry for LT use?

    Is there anything similar to the type the Velodyne HGS series uses? It simply limits low-end output when there isn't enough power. I'm hoping to do a LT sub using the Tumult. Instead of designing the Q of the system to be within the capabilities of normal amps, I'd prefer maximum flat...

    Differences between SVS PCi and PC+?

    What are the differences between the SVS PCi series and the PC Plus series other than the more powerful amp, adjustable subsonic filter, and tunable ports? Is the frequency response pretty much the same? Does the Plus have greater excursion, etc. I ask because I don't really need a fancy sub...

    Question about multiple passive radiators in Unibox

    In Unibox, I have the following parameters for the passive radiator section. No of PR's: 2 Fsp: 8.2 Mmp: 1500g etc... Now does that mean that each passive radiator is to be weighted to 1500g, or that both of them should be weighted to 1500g total?

    Questions regarding Shiva, necessary power, and bottoming out

    A Shiva in a 113L(4ft^3) box tuned to 20Hz seems to give a similar response to the SVS 20-39PC+, so I'm pretty set on this configuration for now. How much power do I need to get the sound pressure level from the Shiva sub to match the SVS (if it's even possible)? I know a lot of people here...

    Question regarding RPTV progressive scan upconversion

    I'm currently selecting an RPTV and am a bit confused with the upconversion feature. "NTSC-to-480p progressive-scan upconversion system improves picture quality with conventional sources." Does this mean that I don't need a progressive scan DVD player? I get the impression that the...

    Quick sound diagnosis requested

    I have the weak Parts Express plate amp with the default boost, and when my sub is playing at high volumes, there's a disturbing noise coming from the woofer (Titanic 10" original). It isn't a loud metallic clanking, so I'm assuming the woofer isn't bottoming out. The noise sounds like a flag...

    How to connect driver to input terminals?

    I have the original Parts Express 10" Titanic subwoofer driver which has binding posts, so that connection is easy. I also have the PE 260-311 terminal cup that I'd like to connect the driver to. The exterior side of the cup has binding posts, but the interior side just has some metal strips...

    Bipoles for corner placement

    Do to my room situation, my rear surround speakers need to be placed in corners. I've looked at all of the major speaker manufacturers and while some have bipole offerings, they're all intended for side or rear wall mounting. Would anyone happen to know if any bipole speakers designed for corner...

    Do resistor wattage ratings need to match the driver's?

    While learning about crossover components, I came across a site that recommended matching the resistor wattage ratings to the wattage of the driver in use. Here's the page: http://www.lalena.com/audio/electronics/rcl/ I noticed that on some DIY sites that explain the crossover and list the...

    Should I match woofer and tweeter sensitivities?

    For my DIY satellite speakers, I don't have the technical know-how to build my own crossovers, so I'll be buying pre-made ones from Parts Express. Since using a stock crossover means I can't add little resistors or whatnot to customize the output of the drivers, I've become concerned that the...

    What exactly is the purpose of widescreen?

    I'm all for original aspect ratio and watching movies as they were intended, but what brought about the widescreen format in the first place? There are certain films like Maximum Risk and the Toy Story series that offer both full-frame and widescreen versions, where the widescreen versions are...

    For bottom-firing DIY sub, what height off floor?

    I have the Titanic 10" driver. For bottom-firing applications, how does one determine the necessary height that the driver needs to be away from the floor? On many sonosub sites, people will mention needing to adjust the height of the feet, but I haven't found an explanation yet.
