yet anther: help me setup my sub question

[Jet_olson]

Hey all,
Take a look at my sig. Any suggestions on what settings would be a good start for both my fronts (large or small; ive heard conflicting things here) and what level to set my crossover at.

Any and all feedback is welcome...

Manually set them to 80hz hp and lp.
Your speaks are rated for about 50 on the low end. If you like the boom effect you can set the sub as high as 120

Enjoy

Awesome Ben..thanks!!!!

Set them to small, set the crossover to 80Hz. See if you like it. If not, move the crossover up or down till you are happy.

Check your sub's high pass rolloff - if the sub start to roll off from 60 and you have your xover to 80 you may have a dip in response between the two. I had to move mine away from 80 because there was a huge SPIKE in the response at 80Hz. Still can't exactly figure out why, but dropping it to 60 fixed it.

Generally accepted is that you can start to localize sounds at around 100Hz, so if you set your crossover there, you may actually begin to hear where your lows are coming from rather than having them sound like they're coming a some uniform direction as with the real low freqs.

Alright I finally got my sub and I am confused...I setup my sub to have its crossover off and put my volume at about 75%. I ran my auto setup for my amp and it set its crossover to 160 (which I thought was high especially considering my fronts) and my subs output seemed low from a volume perspective...I also thought with my RTi8's that I could easily have my crossover set below 90.

It probably sounds crazy but when I left my receivers crossover at 160 and then turned on my subs crossover to 90..the output was much better and sounded more robust for music and movies. Now the million dollar question is that if my receiver's crossover is set to 160 and my subs crossover (im thinking im traveling into dangerous territory here) is set to 90 that I will be missing some range between 160 and 90? Or is that not the case?

P.S. for my receiver I could not set the crossover to off..it only goes down to 40...havent figured out how to turn it off yet.


...any ideas here?

As an experiment put on some bassy music then unplugged your front speakers so that you're just hearing the sub output. First listen to it using the subs internal crossover on and the avr crossover off. Then switch and turn the subs crossover off and use the avr crossover and see which sounds better. Play around with different crossover points. I noticed that using the subs crossover and the avr crossover off- bass sounded tighter, more extension and more impactful.

Using the avr auto set up is fine to start with, but ultimately you have to tweak it to where it sounds the best. I've got my sub crossover set to 40hz. It also helps to have an Avia calibration disk and SPL meter because it is more accurate than your ears. Sub placement is also key.

Ypao and other auto eq programs do funny things with speaker size, distance and crossovers. You should go back and manually set all speakers to small and the crossover to 80. Then go back and disable or turn the crossover on the sub all the way up.
