Low High-Pass Crossover Frequency on AMP (15-250 Hz) -- is it acceptable?

[asilentfire 10+ year member]

I am comparing the Sound Ordnance M-4100 and Sound Ordnance M-4075 on Crutchfield, and the M-4100 has 100 RMS while the M-4075 has 75 RMS. I would like the M-4100 with the 100 RMS but the High-Pass Crossover Frequency is only 15-250 Hz, while on the M-4075 its 80-2k Hz.

250 Hz vs 2000 Hz seems like a dealbreaker, I want those tweeters to tweet.

Please let me know if 250 Hz is enough, I really don't know.

Time out....you're running passive components I'm assuming so this amp won't dictate your tweeter crossover....just how low the mids play....

And I'd look into other amps....

unless he plans on high-passing his tweeters at 250 //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I am actually running full range speakers, so if the speakers are connected to an amp with a 250 Hz crossover it won't kill the treble?

And as you might have noticed, I don't know really understand how crossovers work.. Can it be set to block just the deep bass to the full range speakers and leave everything else alone?

are you running coaxial? or a component set?

it doesnt really matter neways....hi pass means it passes all the freqs up from where you said it....so ideally you are gonna high pass them around 60-90...depending on the speakers.....so the speakers will see everything from 70hz on up.........

Thank you! I thought the hi pass was a range, so it could only play 15-250 Hz frequencies!

I am a little less dumb thanks to you! //content.invisioncic.com/y282845/emoticons/graduate.gif.d982460be9f153bb54e5d4cb744f6ae8.gif

no prob.....the 15-250 IS a range where you can set your crossover point at.....not the range that it will play.....
