The difference for your application would likely be splitting hairs. Either are very capable and it's not like your pushing the power limits of either with 2KW. It's like people who blow thousands on golf clubs thinking it'll help their game when a few months of lessons would likely actually make a difference. People who do change their woofers a lot don't ask, they just buy and test. If you buy right you should lose much on flippping it afterwards and not end up paying too much to audition either.

1) You should set the subsonic such that your excursion is realistic for your sub. Rule of thumb's IMO are not the way to do it. A quick model in Win ISD will show you the excursion for your power and box size. 2) You can measure. Filter frequencies are -3dB points so you could play a 10v sine wave and measure on a voltmeter, keep reducing the frequency until you hit 7.07V and that will be your crossover frequency or 3dB down point. I'd recommend burning a CD with a whole range of sine tones around your frequency of interest and use them. Of course you could use a single one if you know specifically what frequency you want it to be at. For instance, if that were 30Hz burn a 30Hz sine tone on a CD. Play the CD through your system with the filters off and measure the voltage. Now multiply that voltage by .7079. Now turn on your filter and turn the knobs until your DMM reads whatever voltage you just calculated.

I went to a local shop today to price some remote start security systems. I was looking at the Viper 5109. While looking at my truck the shop owner noticed my monster box with an 18 AA Mayhem. Without getting into a long story, he told me that the sub was no more than a true 500 rms sub (keeping in mind that he has never heard of AA) and said that his his two 12 inch Flame series Audiodahn subs powered by a Flame series amp would hit harder and be louder than the Mayhem ( silly silly man). He was so positive he would beat me that he said he would give me my alarm and install it for free if he wasnt.!!! Like I said THANKS AA !!! My alarm will be installed on Wed.!!

Statutory rape charge? Oh wait, that would be for him.. Unless he is in Germany! Cheerleader outfit maybe?

welcome to a great site. Uh, when attempting to point out epic fails and standing your ground for not being a newbie, perhaps a little proof reading would be in order, lol. ^^^ I would say the newbie section is for folks new to this forum, so we have a chance to know the newest members as they join. You say you been on other forums for years, by all means, share some of your experiances , do you currently have any builds? The same rules that seem to bother folks about selling their items, quickly become the ones they appreciate the most when deciding to make a purchase on here. These guys are always looking out for all of the members on here, that is FTW ! chop

there's a user doin over a 150 with a single 8 then there's people with 2 18s and several thousand watts of power doin just over a 150 too so It's all in the INSTALL.

Two Icons. More information about your listening goals instead of those absurdly general ones would help. But it doesn't matter, I'd still suggest two icons.

Wording could use a little refinement, but I think you have the jist of things. Correct, it doesn't matter which filter is set to the higher frequency and which to the lower frequency. As you approach 2nd crossover frequency, the rate of attenuation (or slope) will increase (or steepen). And I just want to clarify that you understand the slope of the crossovers themselves doesn't change. It is the effect of the multiple crossovers summing that increases the final rate of attenuation of the signal. Also want to point out that the word highlighted in red above should be "rate of attenuation", or "slope". Octave describes the interval between frequencies. The term "decibels per octave" is used to describe the crossovers rate of attention, or slope, (in decibels) per the interval between frequencies (octave).

Correct. You can do a basic active setup with the crossovers in some amplifiers, such as the Sundown amps. IIRC this is the reason Jacob chose the frequency ranges he did for the crossovers in his amplifiers. It will not be the epitome of flexibility, but it will technically work.

Hrmph. I guess maybe I presumed you knew something you didn't when I was writing out my previous responses. Suppose maybe I should have began by asking if you understood the crossovers, slopes, etc Maybe this post I made a few years ago will help some also? http://www.caraudio....548&postcount=2 Let us know where you're still a little confused, we'll try to help

If only the person was as good as the sub....

You mean, for example, if we set them to 500hz how would 1000hz be affected? Go back to the BCAE1 link I posted earlier in the thread and look at the graph. I think it would help if we stopped calling the subsonic filter a subsonic filter, honestly. It helps for identification of which filter we are talking about, but I think it might be causing you to think of the subsonic filter as something it's not. Subsonic filter is just a fancy (an in many ways, wrong) term that we use to describe a highpass crossover that can be set to very low frequencies. It is no different than the highpass crossover on the amplifier, or in your headunit. They are the exact same thing, we just use different terms to identify them. We'll call the headunit's highpass crossover Filter 1 and the "subsonic" crossover Filter 2. If we stick with our highly idealized situation and continue to assume they are both the same slope; Setting Filter 1 to 500hz and Filter 2 to 750hz is exactly the same as setting Filter 1 to 750hz and Filter 2 to 500hz. The results would be identical. A better question is; Why would the result be different? They are both doing the exact same thing to the signal. It doesn't matter which comes first if they are both doing the same thing.

Crossovers unfortunately can be an extremely complicated subject. The above wouldn't even qualify as a snowflake on the tip of the crossover iceberg. But for the basics, if you haven't read it yet, you can start here; http://bcae1.com/xovrslop.htm

I guess I'm a little confused on what it is you are actually asking. Jacob's description is spot on. But I'll give it a shot and we'll go from there. A subsonic filter is nothing more than a highpass filter (crossover). Filters (crossovers) are cumulative; If you are using more than one filter, then the slope of each filter used will combine. For example, lets say you have the highpass filter on your headunit set to 500hz, and it's slope is 24db/oct. You then also use your amp's 24db/oct subsonic filter and likewise set it to 500hz. We will assume both are butterworth filters, which means the crossover frequency is the point at which the signal has decreased by a level of -3db. Now, in this particular scenario since we are using two crossovers of the same slope and alignment, both set to 500hz, the net result is that the signal will be down -6db at 500hz and the net slope will be -48db/oct. This is because, as noted earlier, the two crossovers combine. They both affect the signal. Or we could cascade the filters. We could set the crossover on the headunit to 500hz and set the subsonic filter at 250hz. In this scenario, the signal would only be down -3db at 500hz and the slope at that point will continue at the original 24db/oct rolloff. Now, normally at 250hz (one octave lower than 500hz) the signal would be down -24db due to the 24db/oct slope of the headunit's crossover. However, as we approach 250hz the signal will begin to decrease in level quicker than 24db/oct because the 2nd, cascaded, filter (in this case, the subsonic filter) will also begin affecting the signal. The signal at 250hz will instead be down -27db (original 24db/oct slope + -3db from subsonic filter) and from there continue to decrease at 48db/oct due to the combined effects of both the headunit's 24db/oct filter and the 24db/oct subsonic filter. So the frequencies below 250hz will be attentuated much more quickly than above 250hz. This can be done with any two filters (crossovers). You could use the lowpass crossover on your headunit and the lowpass crossover on your amplifier to obtain the same affect on the top end of your midrange, for example. Or the highpass in your headunit and highpass on your amplifier to steepen the highpass filter on your tweeters. Etc. This is a simple, idealized example for explanation purposes. In reality there may be some other factors to take into consideration such as the Q of the filters and such.....but it should provide you an idea of what Jacob was talking about. Clear as mud ?? Help, not help?

do u seriously have to post here before u can post any where else?? if so that is an epic fail! and im not a nebie i been on other fourms for years!

can anyone just grow a pair and answer my question without saying "its all in the install"? cuz i mean you could say that to literaly any situation. you could put a ported 18 in like a 1 cubic foot ported box and it probably wouldnt be as loud as a 12 in a 5 cubic foot box. im not gonna hold anyone to their answer. my friend just asked me which would be louder, so i figured id post something up on here and ask some more experienced people. someone just give me their best estimated answer. it doesnt matter if your wrong. just give me your best opinion.
