subwoofers (how they sound) question... - Saxperience

infinitym4ge · 14th January 2009, 23:02

I was told in a good sound system, you should have no vocals or higher frequencies only the thud of the bass? is this true? i only have a sub setup in my boot rightnow with no other speakers and i get the whole tune..

could someone please explain this a little more.

your sub is for low base only and wont give mid or high bass, your front speakers give mids and tops, are you saying you dont have any front speakers on a sub?

infinitym4ge · 14th January 2009, 23:22

no what i mean is i only have the sub hooked up, but i dont only get low bass i get all 3, when i have my comps hooked uo will the sub only give off low bass? or have a messed up somewhere?

have you got you sub setup wrong, does you sub give out vocals? sound like you need to tweak your amp and mess around with you hd, or upgrade the hd and huck up some good front comps and see what happens.

hd = headunit?

you need to set your amp to low pass mate as it is promle set to full/high pass, someone should be able to tell what frequance you wont i normaly set it to about 80

i though it had to do with the amp, i just need to mess with the settings a little.

there setting on the amp, on one of the sides you will have the switches

Depends on the sub, read your specs. Generally a good setting for a sub is 100Hz as it normally provides a good crossover point between itself and the woofers. Can be as low as 50Hz and a lot use 80Hz. Make an educated guess between the optimum for your sub and the lowest frequency of your woofer.

As someone has already said your current problem is that your are sending the full range of frequencies to the sub (which you shouldnt) its not designed for it and will reduce its performance. You need a crossover in your system somewhere, hopefully you have one on your amp, which may be as simple as a switch marked full / low (go for low)

i have this amp on the way with a nice sub, i think this will do the job. it has a 12dB Octave Low pass filter variable 32Hz-320Hz

Yes thats fine, turn the low pass filter on and set it about 100Hz as stated above. That'll keep the correct frequencies going to the correct speakers.

If you read the rest of the thread youd know we are talking about wiring up the amp for his sub, so a crossover frequency of 100Hz to a bass unit is correct. You can put as many high frequency (20,000Hz) signals as you like through a sub, its not going to play them.

subs woofers as the name suggest are designed to play the low freqs

such as 20hz - 80hz (that kind of range)

your amp settings will allow the HU to send higher freqs to the woofer if not set up properly

ie: the "LPF" setting - simply turn it on

also, its best to upgrade to a good front set up before adding a sub

McBain · 16th January 2009, 15:41

Subs, as the name suggests, are generally used for producing frequencies across the low sub-bass range (up to 90Hz) although most will play a lot higher.

What headunit have you got? On some you can set the filter/crossover points at the headunit and leave the low pass filter off on the amp, otherwise you'll need to set it at the amp.

Start between 70Hz and 90Hz and go from there.
