    Not sure which forum this should go under. I've notice that low quality IPTV channels will have kind of a hi frequency hiss during the dialogue. Is there anyway to cancel out that trailing hiss?
  3. Dedicated Theater Design & Construction
    Hello - I have been reading and hearing various conflicting test reports and advice regarding the weight (or gauge, if metal) of a wall frame, for optimal isolation. Any consensus or definitive advice available on this? In my case, I am mainly interested in low-frequency isolation. I already...
  4. Audio Theory, Setup, and Chat
    Hi, I just wonder approximately how much the grille on speakers affect the frequency curve? Is it e.g. 1, 2 or 3 dB at the frequencies affected most? Also, are speakers normally measured with or without grille when the manufacturers specify the frequency range and curve? PS. I know this may...

    I have a question regarding crossover frequency setting. My setup: -Onkyo SR507 amp -Front L+R: q-acoustics 2010i -Center: q-acoustics 2000Ci -Surround L+R: Cambridge Audio Minx Min 12 (crossover freq specs= 150hz) -Subwoofer: Onkyo (came with the amp) I recently added the 2 Cambridge...
  6. Audio Theory, Setup, and Chat
    Hi, Often you hear people saying that the rear channels in multi-channel movie sound do not contain low frequency sound. So I just wonder: 1. What is the theoretical frequency range of the rear channels? 2. What is the actual frequency range of movies in general? E.g. typical vs max lowest...
  7. Subwoofers, Bass, and Transducers
    Hi, Often when people are comparing subwoofers, they compare what max SPL they are capable of producing at the lowest possible frequency. If one subwoofer has a higher SPL than another, it "wins" and is thus considered to be a better subwoofer than the other one. But does that really tell the...

    Hi, When discussing subwoofers, it's often mentioned what SPL they can reach at different frequencies. But what about other speakers, such as bookshelf speakers? In reviews of those you mostly see a frequency response graph measured at very low output (e.g. measured at 2.83V input). Something...
  9. Subwoofers, Bass, and Transducers
    Hi, As an example, the SVS SB-1000 has this frequency response: According to the specs, it's 24-260 Hz +/- 3 dB. Now let's assume the A/V receiver EQ is set to bump the frequency at around 20-22 Hz or so by a few dB (3 dB or so). Then wouldn't that mean the subwoofer is capable of perhaps...
  10. Audio Theory, Setup, and Chat
    Hi, Loudspeakers with bass reflex ports are designed to produce a flat or optimal frequency respons with the ports unplugged. Still some loudspeakers are delivered with port bungs/plugs used to plug the ports e.g. if they are placed close to a wall, to reduce bass resonance. But will using...

    What frequency should I tune my custom subwoofer box for optimum sound performance? I plan on using this driver from Parts-espress; http://www.parts-express.com/dayton-audio-rss265hf-4-10-reference-hf-subwoofer-4-ohm--295-460?AID=1457483&PID=6155355&SID=v535dhf3l7x6 According to driver specs...
