Rig question

I have a Carvin BX500, with a Carvin BRX210 cab. I am thinking of changing my rig to get a more powerful, clean sound.

What will happen to the overall sound of my rig if I.....

a) just add a second 210?

b) buy a new amp - Carvin BX1500, and get a second 210, and either bi-amp or bridge and run into the two 210.

c) buy the BX1500, and get the Carvin 115 cab, and bi-amp with the 210 I already have.

I am a middle aged guy and a relatively seasoned musician but am fairly new to electric bass.

I play a bass with humbuckers, and with the existing rig I have, it seems difficult to get the kind of volume I want with a pristine clean tone.

The overall tone of my rig is ok; the Carvin amp is very adjustable and my bass has a pretty versatile pallette of tones I can get.

But I would like to be louder while maintaining pristine clean sound. When I get really loud with the existing rig, it's almost as if the sound is distorting a little. This is fine for some songs, but overall my ear wants gobs of clean clean volume.

Go easy on me fellas....
 
a) just add a second 210? You gain about 6 db of volume. 3 from the additional sensitivity of your cabs, and 3 from doubling your power handling.

b) buy a new amp - Carvin BX1500, and get a second 210, and either bi-amp or bridge and run into the two 210.

Not going to have a huge volume gain over your current amp. Two 210's are pretty much going to be mechanically limited to around 500 watts. So you would gain some head room, and eq. There is no reason to bi amp full range speakers.

c) buy the BX1500, and get the Carvin 115 cab, and bi-amp with the 210 I already have.

wouldnt be as loud as two 210's. There is no good reason to mix full range speakers.


What I would do is start out with adding a second 210. Then if that isnt enough I would look at the BX1500, and start adding more of those 210's. You can run 8 of those 8 ohm 210's with that amp, and have enough power to drive them to their limits. If you are looking for a tonal change as well, then you are looking at other options. Either switch out the cab(s) you use with your carvin amp, or get a different amp.
 
Any speaker cab has limitations as to how much input power it can handle "cleanly". Adding additional power to a single cab may just result in power compression (a distortion of the signal by driver exceeding its mechanical limits and using the additional power to produce waste heat).

First thing to increase sound level is more speakers (radiating area). Speakers are not efficient at converting amp output power to audible sound (by mechanical movement of the cone) so doubling the number speakers increases that efficiency by a factor of almost 2.

Long way to agree with adding the second 210 before you try anything else. Amp output power alone won't get you there.

A fire hose will put out a lot of water, but hook up your garden hose to a fire hydrant and the output will not come even close in comparison. Even though the massive amount of available water is the same. :)

+1 to stacking the speakers in vertical alignment.
 
Thanks guys. Actually, the 210 is 4 ohm, but the amp can go down to 2, so I can still get another 210 with this amp. At a gig last night I used my carvin head with the club's Hartke 410 (8 ohm, 400w I think) and I loved the tone.
