are 24db slopes better for my components?

[noob with an RS 10+ year member]

do 24db slopes generally or USUALLY sound better for components? i just sold my 24 db/octave crossover so now i have to use the crossover on my amps. the components amp uses a 12 db slope.. im wondering if i shouldnt have sold my x-over?

i think the slope is the roll off from the set frequency... since a crossover isin't a brick wall the slope determines how quickly the signal fades from the set frequency, i always thought its better to have a higher slope but i could be wrong. Either way, as long as the slopes on the comps mids and tweets are the same it should sound the same (i think).

some one correct me

That's exactly what it is. The roll off from the set frequency. A 24dB/octave slope is much sharper than a 12dB/octave slope so the range of frequencies outside of the cutoff point that are allowed to pass will be much narrower. For the average user it won't make that much of an audible difference.

if i have 12db/slope crossover on my fronts and 24db on my subs will it sound worse than having 24 db for fronts and subs? my hifonics nx600 is 12db and my 1501d is 24db.

I dont think you get what a XdB/octave is do you? I say this becuase it wont really make a difference in the sound. Esepcially not the SQ for a person like you.

this is bullshiit where the fuk is my cookie?

i want it NOW!

there's only two real ways to know which is better A) mic and graph the frequency curve and use the one which gives the flatter frequency response or b) listen to both and choose which one that sounds best to your ears. Theres NO way someone can tell you which is better from their computer chair. Some speakers may match better with 24db/oct slopes some might work better with 12db/oct slopes. The crossover point and where the speakers dip, peak and roll off are all factors.

it doesnt really matter, you could use a 24db or a 12db slope, the 24 will just drop off faster

look, if you use like, 24db slope and the frequency is 100, i might sound the same if you used a 12db slope and a frequency of 65, get it.

This is a question without a definite answer. There is no better and worse; just whichever works best in your particular circumstances. And it's definitely not something someone can answer from over the 'net.

Too many variables, no way to know for sure which works best in your install, with your equipment, with your personal preferences, etc etc........

yeppers.

but my horns are pretty finicky, and im using a 24db\oct xover because i dont want to bottom them out //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Situations where a shallow slope could result in bottoming the driver out are precisely where it matters most. A steeper slope gives you FAR greater versatility, because you can use a lower or higher XO point, depending on whether you are talking a HP or LP filter.

Biggest advantage is versatility. Will it make an audible difference in all situations? Nope.

thanks mr warbleed for chiming in.

my situation dictates for a 24db\slope because of the horns and how percise i need them to play at the highpass point.

basically, you might be able to blend the speakers differently with different slopes, but again - its all install dependant, a 12db\oct slope might be perfect for your car, or it might be horrendous. your only way is to test different slopes. but that, sadly, is usualyl not an option //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

You could use a shallower slope.....I was running 18db/oct on mine for a while. But, you'd need to bump up the xover point (I think mine was around 1100hz or 1200hz w/ the 18db/oct slope, whereas with 24db/oct I can go down to atleast 800hz).

However, on the highpass for my mids I've been using (and preferred) 6db/oct @ 52hz up until just recently when I installed my Next components, where it sounded better with a higher point and 18db/oct. But, that's because they aren't the greatest for midbass output or low frequency extension. They handled 63hz @ 12db/oct fine mechanically, but tonality and accuracy cleared up a ton when I bumped up the point and slope

well the thing is my audiocontrol EQX uses 24 db slopes and im liking the way it sounds. some dude has sent me paypal for it.. 135 dollars. i sold it to him because i wanted to upgrade to the EQS which has six channel inputs. i just learned it doesnt have the crossover the EQX has so i would have to use the crossover on the amp if i were to use the EQS. i dont know if it can still sound good with the amps crossover.. im going to cry. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

It will make a diff in sound, it's more or less if you, and your mids for that matter, mind it. NAUC needs to switch the slopes around for that to be correct. 100Hz @24dB/octave will yeild about the same results as 200Hz @12dB/octave. You'll mostly want to look at the speakers freq. responce to determine how low you can go (what freq). A steeper slope will allow you to go lower on your X/O point, but not to much lower.
