    Wow I might just purchase one if they are as good as you say they are for the price. My 10" klipsch just isn't cuttin it at 100watts. And for ~$120 Can't really seem to go wrong. Let us know how it turns out for you.

    what should the frequency be set to for best sound on the back of the sub?
     
  12. IceMurder

    and for some reason when i set it all the way down, 40hz, i get no sound at all from the new sub...but my older cheaper smaller one goes down to 30hz and i can still hear bass....is it defective??

    Hmm You should still hear sound unless you have some sort of cutoff that doesn't send signal below 40hz set on the receiver or something. So it has a down fireing vent rather than front or rear I don't think I have ever seen that. I wish I could come over and listen:hs:

    I have mine set between 70 and 80hz. Seems to work for me, but I'm sure someone that knows what they are talking about will tell you different.

    Where you set your crossover is entirely dependant on sub location, sound stage location, and how low your other speakers can play.

    Get a test track CD to do your testing. You want dont want the sub to be localized with your ears. Put a sweep on repeat and start with the sub in a corner. Move back to your listening spot and gradually go back and turn down the crossover untill it is hard to tell where the sub is. If you were a true audio nut you would bring someone in who doesnt know where the sub is and have them try and decipher where the sound is comming from.

    I reccomend putting it in a corner for maximum amplification. However, this may create standing waves so if you use it for music and you will be up and moving around you may want to move it to a more open environment.

    yea no sound at all below the halfway mark on the freq. the knob says 40h-130hz and i only hear sound when i go past halfway...but my smaller sub i can hear the bass well when i turn it down to 30hz, i dont understand :hs:

    and yea the down firing vent is new to me as well, but it sounds good when i have the freq. turned up :dunno:

    i read a website that said turn the freq on the sub all the way up and set the crossover on the receiver to 90hz, true or false?

    and its in the corner already, its the only place i have room for it

    I guess it just depends on if you have a receiver capable of doing so and if you want to have the receiver control all of the crossovers. So Hows it sound good, loud, crisp?? The whole frequency thing kind of worries me.

    i mean the old sub hooked to the same receiver will put out bass at 30hz, the new one doesnt...but it says on the site it will go down to 24hz so i dont understand why im not getting anything that low


    but yes, loud and crisp when the freq is turned up half way

    Hmm I really want to buy one but I really don't like the idea of not being able to set the frequency at whatever I want. How is it with like rap music or music in general with a lot of deep bass? I know my klipsch has the tendency to distort when played at moderate volumes.

    i havent turned it all the way up but at half volume it sounds real good, no distortion

    You're misunderstanding how that control works.

    That control sets the cutoff point of your monitors. More accurately, it sets the point at which the monitors roll off at on the low end, and where the subs come into play.

    If the sub is going somewhere reasonably close to the middle of both monitors, you can safely set the cutoff level at 100hz.


    Here's some basic math for you to understand, so that you can have a better idea of what is going on.

    At 80hz you have a 14 foot sound wave.

    So say you had your monitors 14 feet apart, and had the sub in the exact middle of the monitors, the sub would then be creating a bass signal just barely wide enough to be percieved as coming from the monitors.

    The best rule of thumb that i've seen when it comes to loudspeakers, is to go 1.5x less than your limit.

    So at 80 hz, you would 112", or about 9.5 feet apart for your monitors.

    At 130hz, you only have an 8.5 foot wavelength. Taking the 1.5 rule of thumb
    those monitors need to be no more than 5.7 feet apart.

    Now the 1.5 rule is not carved in stone. Going from 8.5 feet to 7 feet might be just enough to make it work.

    At your 40hz setting, your sub is pumping out a 28 foot wavelength.
    So going by the 1.5 rule, you could have them 18 feet apart.

    And at 100hz, it's an 11 foot wavelength, and a comfort zone of 7.5 feet.

    Now mind you, all of those examples assume a sub that sits near the middle of the monitors.

    Park that sub to one side, and you throw the numbers waaaayy off.

    For what it's worth, the ideal situation is a separate sub directly in line with the monitor.
    Distance does matter - but not a lot.

    i emailed the customer service and this is what they sent me

    Hello,

    Contrary to popular belief, distortion does not cause speaker damage.
    Distortion is merely the audible detection of signal "clipping". Clipping
    is when an audio component can no longer provide enough power supply
    voltage to "cleanly" amplify the audio signal. Clipping can occur at any
    point in the signal chain (source unit, signal processor, amplifier, etc.)
    The popular belief is that if an amplifier "clips" it will send D.C.
    current to the speaker's voice coil and "burn" it. THIS IS NOT TRUE. It
    would surprise you to realize nearly every car audio system's amplifier
    "clips" when listening to music at moderate -to- loud levels. Electrically
    overpowering a speaker is caused by continually playing the audio system
    loud, resulting in applying more power to the speaker than it's "rated"
    specifications. This is what causes speaker voice coils to "burn".

    However, for "sound quality" reasons it is important to match the source
    unit, signal processor and amplifier gain settings to optimize levels and
    minimize noise floor (system hiss.)

    Regards,

    Zack

    90Hz is pretty high and deffanitely stepping into the directional zone. 60Hz or so would be my personal maximum for HT.

    So how does this relate to the cutoff not working properly? If this is their answer for that then I don't want to even try and purchase one if their customer service is going to be a PITA about exchanging for a new one.
