    No sub on CDs?

    Not sure about your set up but it may have something to do with only having the digital co-ax hooked up. I think, but can't be sure, that if your receiver gets it's signal from the digital co-ax, it's looking for the 5:1 digital dobly (AC3) mix. Since a music CD is missing the :1 signal for the...

    What makes a sub musical?

    OOPS- my mistake. I meant to type "...does NOT play...." I'd edited it. :b Of course I knew that there would be no sound produced in the vacuum of space. Therefore the law of F=MA (which stills applies) would have no relation to the sound produce because there would be no sound produced...

    Hey Robert, turn it up a little more and let me hear what it sounds like from where I'm sitting.:D

    What makes a sub musical?

    I know F=MA is a way over simplification of how the dynamics of a electro-magnetic driver works. I was just trying to convey in a simple way how servo-control can alter the moving dynamics of the driver by controling the force. But........... What's wrong with my logic here. I hook up two...

    What makes a sub musical?

    It's not how "fast" the driver is moving WHEN playing a 20hz signal but how "fast" the driver responds and actually begins to play the 20hz signal. And just as important, how "fast" it stops trying to play the 20hz signal after the signal has stopped. The mass of the driver, the elastic property...

    What makes a sub musical?

    F=MA- Force is equal to Mass times Acceleration Increase the Mass and Acceleration must decrease if the Force remains the same. Increase the Force and Acceleration must increase if Mass stays the same. If you increase the Mass then you must increase the Force for Acceleration to remain...

    What makes a sub musical?

    Speed is the other quality that "muscial" subs have. Most "muscial" subs are built with 8" or 10" drivers. Not too often with 12" and rarely with 15" drivers. The less the mass the faster the drvier can move. If more output is needed then they use multiple 8" or 10" drivers per enclosure. High...

    Do looks matter?

    Haven't you hear? The better the component looks the better it sounds. If you don't believe me, just compare the sound of a $20,000 Krell Preamp/amp to a $600.00 Rotel reciever. Since some of us on this board contends that all electronic sounds the same, then the difference I hear must be...

    Should I get into vinyl?

    P-mount arms add mass to the tone arm where you least want it, at the cartridge end. This makes it harder for the arm/cartridge to properly track the groves as it moves across the record. Specially if there's a slight warp. Even if you properly balance it for 3/4 or so gram tracking force, the...

    Blade Runner tops scientist poll

    What happen to "Silent Running" and "Soylent Green" and "Logan Run". All truer to the gendre of SciFi than Stars Wars. Science fiction should at least have some message about the future of Earth or humans. Not about something that happened a "long time ago in a galaxy far, far away." But I got...

    Bass Shaker connection woes

    Just taking a stab at it. Not seeing what your sub amp looks like and your description of the problem is a little confusing. It sounds like your sub amp has a built in preamp. If thats the case you need to jumper the line out (preamp section) to the speaker in (amp section). You can do this...

    I just blown up two amps in one week-end

    Don't AMEX offer a no question ask protection policy for the replacement for anything bought with their card? I kind of remember seeing commercials of consumers dropping, losing, stolen, dog chewing up and kids breaking items bought with the card and AMEX will replace it. This was a while back...

    Large strand vs fine strand speaker wire

    So let me get this straight. Supposed you heard Yogi tube system (with your ears) and deternmined that it sounds better than your system (I don't think there's a good sounding tube system that don't react to the load). Do you break out your meters and o-scope and proceed to tell Yogi what a...

    Hafler amps???

    I'm still using a Hafler D-500 and two Haflers D-200 that I purchased in kit form back in the mid 80's. Back then Hafler was an affordable way to enter into "High End". Hafler was one the best amp for the bucks (along with Adcom). The kit form saved you 100 to 200 (depending on amp) bucks and...

    How many years are CD players good for??

    I think the 5 years life span pertains to the time frame in which the average consumer will replace his/her consumer grade electronic equipment because it has become obsolete (it's about 3 years with computers). People start to think replacement because their old (but still functional) equipment...

    Firewire mystery

    I may be wrong but I believe Firewire and DVI are used for different applications. Firewire is use to send raw video data to a piece of equipmnet that will process the data and turn it into a video signal. DVI on the other hand is for sending a digital video signal. When I hook up my camcorder...

    Would my subwoofer give me better performance if I set it on a piece of wood?

    If you want to try something that may improve the sound, try getting some speaker spikes to go through the carpet and load the sub to the floor beneath. Now, you may or may not hear any difference from where you're sitting but any downstairs neighbors (if you have any) will surely inquire about...

    Martin Logans

    Been an owner of a pair of ML CLS 2z's (with Entec subs) for nearly 10 years now. Though I can used them as HT front speakers, I very rarely do so. Most of the time I use my pair of Boston Acoustics for HT front speakers. The ML are so musical that I really can't stand the thought of playing...

    Want Good Turntable w/Easy Speed Switching

    No one leaves my home thinking that CD's sounds better than vinyl (at least not the CD's I own vs the vinyl I own). Most people think that there's nothing complicated about playing a vinyl record on a TT and that their $100.00 or so TT that came with their rack system is adequate. After all, the...

    series connection for shakers....

    You would be better off connecting all three in series to get 12 Ohms rather than add a resistor to get 16 Ohms. If you want to work at it, what you need to do is create 2 16 Ohms load and hook them up in pararell. Another words, you need to add a 12 Ohm resistor to the single shaker and an 8...

    Reversing the fans on a Samson amp

    Curiousity got the better of me so I went and wired up a shop vac so that I can place a clamp on amp probe on the hot leg. (I did this by splitting apart two wires of a two prong extension cord and using a cheater plug on the vac.) Sure enough, just as I knew it would. The amp probe read 6.95...

    Reversing the fans on a Samson amp

    I may be wrong but I think a fan is more efficient operating under "negative" pressure. When a fan is sucking and the internal pressure drops, it is easier for the fan to move because there's less air pressure on the blades. This causes the fan to spin faster and lead to greater negative...
