You don't want to high pass your speakers too low...you don't want your subwoofer to play much above 80Hz, if that.

turn the bass all the wya down on your HU first

I dont understand if i set the high pass on my speakers at 200hz doesnt that mean that only freq above 200hz will go thru the speakers? because i want no bass at all to come thru my door speakers. the sub is more then enuff for bass.

I wish it was that easy man. its not just treble, and bass u gotta do frequencies.

You want your speakers to play lower than that, having a gap in your system's frequency response is not a good thing. Your sub isn't meant to cover midbass, just subbass...which effectively ends at 100Hz or so.

Unless you're tone deaf, in which case none of that applies.

i looked up the specs on your pioneer deh-7800mp and these are the high/low filter ranges it has

High-Pass Crossover (HPF) 50/63/80/100/ 125/160/200Hz, 0/-6/-12dB/Oct

Subwoofer Crossover (LPF) 50/63/80/100/ 125/160/200Hz, -6/-12/-18dB/Oct.

pending on what sub you have and stock speakers you could probrably set both of the filters to 100hz on each. meaning your 4 speakers should only play notes above 100hz, it would be little mid bass and most likely won't hurt your speakers.

setting the sub filter to 100hz should allow it to play notes 100hz and below.

if you are not sure that the filters are doing what they are supposed to do. download some frequency test tones around like, 90-99hz. turn OFF the sub(should have the option on the HU) and listen to see if you hear the notes coming from your speakers, if it doesn't then your in the clear. then turn ON the sub and test again to see if it moves, if it does your filters should be ok. find some tones around 100-115hz if possible as well to see if the sub is playing notes above 100hz when it shouldn't be if the LPF settings are set to 100hz.

just remember this..

HIGH Pass filter = Frequency setting and ABOVE

LOW Pass Filter = Frequency setting and BELOW

hope that helps.. or if you even understood that //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

---------------------edit

i found that you have an amp pushing your speakers.. your amp itself should have a high/full/low pass filter switch on it.. on the switch set it to HIGH, locate the HP Crossover knob. it should have a range of 80hz - 1.2k just turn the knob a notch, maybe a quarter of a full rotation. the amp itself SHOULD cut the bass going to your speakers.. but turn OFF the subwoofer when running these test so you can actualy listen and make sure that your speakers are playing bass..

Doesn't work that way hombre.

Crossovers are not brick walls, they simple attenuate the frequencies above/below the crossover point based on a certain rate, called the slope. This slope attenuates the frequencies at a certain decibel level per octave. If those specs you listed are correct, then on the highpass side he has the option of attenuating the frequencies below the crossover point at either 6db per octave or 12db per octave.

Therefore, if he set the highpass crossover point for his speakers at 100hz, then 90hz through 99hz would still be clearly audible even though the crossover is functioning perfectly. Likewise, if he lowpassed the subwoofer at 100hz, then 101hz through 115hz would still be clearly audible even though the crossover is functioning perfectly.

Savegoodautonfg; What crossover slope are you using, since that unit apparently has adjustable crossover slopes? If it is set to 0db, then the crossover is effectively bypassed and hence not functioning at all.

i see i see, we all learn something new everyday.

Just to add a bit to squeaks post, which was nice BTW. An octave (in case you didnt' know) is actually 1/2 or 2x the starting frequency. Meaning if you have your speakers on a 12db/octave hpf starting at 80 hz. Your speakers will be 12db's lower at 40hz, and 24 down at 20, so on and so forth. It works the other way too, a octave above 80hz is 160hz.

WIll these really take the bass away compeltely?

I look here on ebay for them. http://search.ebay.com/search/search.dll?sofocus=bs&sbrftog=1&catref=C6&frpp=50&from=R10&maxrecordsreturned=300&satitle=Bass+Blockers&sacat=-1%26catref%3DC6&sargn=-1%26saslc%3D2&sadis=200&fpos=10980&ftrt=1&ftrv=1&saprclo=&saprchi=&fsop=1&fsoo=1

now which ones would i want like 0 to what frequency beacuse there all different ones. i want no bass at all out of those speakers. which ones would i want then?

just uninstall the woofers and run tweeters and subwoofers if that's what you want

you obviously don't care how it sounds

best of luck
