I can shake the walls, but I'm losing tone:

Assuming you want minimal financial impact, start with a new speaker cabinet.

You don't shake the walls, you just encourage them to vibrate on a frequency they are happy to vibrate at. It takes very little energy to do that. If this turns into a persistent problem you should get a single parametric equalizer that can adjust the width of the band. Then you go and kill that particular frequency as narrow as possible. Same principle as killing feedback on a microphone.

Better yet, when you have that rig, bring a girl to the house and have her press her butt on to the cab while its cranked and playing the low B...she'll never remember your guitarist, singer OR drummer's name anymore... Instant Bass Groupie Maker...certainly worth the investment

I really have to laugh at all the comments about a low power amp not being able to shake walls.

Here is my home practice rig.
5 whole watts that will shake pictures off the wall and stuff off shelf's.
and I do not live in a cardboard box.

I guess it was stupid to think 15 watts could shake walls. Should I move it onto the concrete floor? Also, thanks for the suggestions about the EQ, I will totally be trying that!!!

Thanks!!!

Stupid? not necessarily. Naive? Likely.

HD.... Any mods to the epi?

10 inch speakers cut through with more clarity than 15s or 18s. The human ear can hear frequencies between 20 to 20,000 hz. Some people can hear frequencies that are a little lower of higher. Other people can't hear as low as 20hz or as high as 20,000. When you drop tune you are in effect lowering the frequency range. Adjusting your eq should help. Here is a site that might help.

Did you try to tuning up to standard E as an experiment- Or is that blasphemy against your Nu-Rock/Metal? ;-)

The first thing I would recommend is learn about sound, equipment and how they interact, to make them work together. You can mess with the controls all you want but until you learn which frequencies do what, how we hear them and why adding to one range can make great sound and adding just a little to other frequencies can make it sound like crap, you'll struggle with "your" sound.

If you really want to tune down to C, you not only need different strings, you may need a different bass and you'll definitely need a different amps/speaker(s). A bass that's producing extremely low frequencies (below the normal bass' range) requires certain things in order to do this well and an amplifier that is producing these frequencies has to be a lot more powerful- humans don't hear the extremely low or high frequencies as well as we hear mid-range, so more power is needed for the low end to be heard as well as the mids. Add the fact that most speakers won't handle the signal coming from a bass amp, especially if the driver or cabinet don't allow it- this is a formula for problems.
