If i lean forward, my bass is much louder, why?

try switching the phase or tinker w/ T-corr if you have that function.

Like I said basic acoustics. The resonance nodes are frequency, install (sub position and facing) and vehicle dependent. There will be a different node for every frequency. The wave doesn't have to "develop" it's simply a matter of the phase relation between the direct and reflected wave. Facing the sub in different directions affects this phasing by having the wave reflect at a different point in the sine period.

That makes sense to me. Thanks for sharing your knowledge! I was trying to remember what I learned in my electronics class some years back, evidently I misunderstood.

Most people here don't know, or understand basic acoustics //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

You need to install more ohms. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

hmm. i always thought you subtract them.

learn something new everyday.

I think the Lounge has a virus. It's spreading.

1 cancellation

2 wave length... sometimes you can adjust the phasing(most good amps have a phasing adjustment sometimes putting it a bit out of phase help pull that wave closer to your sitting position...

a few Kenwood amps have those phase adjustments

i really haven't used kenwood in a LONG time i know my RD 1750s have the infinitely adjustable phase(0-180) i'm pretty sure most good class Ds these days have them as well...

i used a Kenwood 7201, that's all i've used of Kenwood.

or you can just switch the speaker wire. + to - - to +

You move one frequency's resonance node at the expense of all the others.

Any of the EE guys know how the phase shift circuit works on these amp and do they have a center freq? Every phase equation I've ever seen has freq as one of the variables. That would mean that you phase shift each freq a different number of degrees. Of course the inductance of a speaker's voice coil does the same thing.
