the bass sounds too high. bass boost-5/18

gain-.5/2

lpf-50

Are you saying the bass is too loud? Turn it down.

so you're telling me that the 0-80hz can hurt your ears?

um... ya

no. the bass does not sound low. they sound high. the amp is mono amp so there is no hpf, so thats not the prob.

im goign to fix my gain tomorrow. gettin rain like crazy.

turn the bass boost down, turn the lpf to 70, and turn the gain up until it sounds like it is at full volume, then back off it a bit.

does the amp have a subsonic filter or high pass filter?

and maybe the ported box is just louder then the old sealed box and hurts your ears?

ahh. i thought the tuning affecting the frequencies.

A box has a tuning frequency, which is basically the frequency where the back wave from the sub is most perfectly being inversed and coming out in phase with the front wave of the sub.

You're right about the effects of the sub on tuning frequency and that the sub plays no role in altering it but that the sub will play a role in the alignment of the sub/enclosure system. However, in a ported system, the back wave never comes out of the port. What you're describing is actually a horn where the back wave is delayed linearly along the line and can will be in phase at the tuning point of the horn. In a ported box, the mass of air in the port moves back and forth like a passive radiator would and it moves the most around the resonance. That frequency where the port is most excited is the tuning frequency. The port can be in phase with the driver but more than likely it will not be anywhere near in phase.

That enclosure looks to be about 1.2 cubes tuned to 40hz. I wouldn't expect any sub to really get low in that enclosure and it would probably be very peaky with those Kenwood subs.

So would it be safe to say that the OP's subs would be better off in the sealed box that he had?

Also, since he hadn't screwed the subs into place, is it possible that he is encountering some air leaks around the subs or some other anomaly due to not screwing the subwoofers in?

ETA: I always preferred the sound of a sealed subwoofer enclosure because the sound seems smoother than a ported enclosure which tends to be extra loud at the tuning frequency.

to the OP, put those kenwoods in a sealed box, then go ported when u upgrade subs. ive got a local kid around here with a jbl 500 watt amp pushin those same 2 subs in a sealed enclosure, and it sounds pretty dam good for what it is.

 

[skateboardkid 10+ year member]

you havent even screwed the subs in and they make enough pressure to hurt your ears?

I dont know what to sa to that, you could get a much better ported box from someone on here I bet. That "scorpion box" just isnt set up to sound that great, playing tones on a mic it might get you loud but it is not gonna win any SQ competitions.
