How to control volume of second cabinet only?

If the end goal of what you are trying to do is reduce the amount of bass in your sound, I would first use EQ, starting with the 100hz region. Making your 15 quieter is not necessarily going to reduce your bass content, it'll just make you quieter everywhere. Even if the 15 does put out more lows than the 210 (not a given) it will only be by a small amount, making what you are doing a convoluted and not very effective solution.
 
Something like fdeck's HPF, or some kind of adjustable HPF may also get the job done. If you're going to do the pad on a woofer, you'd better use some really beefy ( read expensive) resistors, or banks of smaller ones....also expensive.
 
I agree with the poster who said to sell your cabs and just get one cab that has the sound that you want. As others have said, the only realistic solution is a second amp or stereo amp. Of course, that's complicating things. You have cabs that just don't seem to work well together. Getting a good full-range 4x10 or 2x12 will save you a needless headache.

Also, I don't understand how a power attenuator would solve your problem, unless you have a stereo amp, which again, would probably solve the problem to begin with. A power attenuator is going to affect the entire load, so the volume ratio is still going to be the same between the two cabs. :hmm:

I completely understand what you and others are saying and it makes perfect sense. Except for the fact that this is not the issue, I love the sound that I have. I do not want to change the sound, I want to be able to control the volume on one cabinet for different applications. If everyone could stop thinking of this a a tone control issue and focus on it as a volume control issue it would keep the discussion relevant.

My original post spelled out that it was about volume control, but when I answered somebody's question as to why I wanted to do this? That's when a lot of focus shifted to tone.
I apologize if my answer was not concise enough for some, I will be more careful in any future posts I make. Many understood it was a volume issue and I really appreciate those whom have made helpful suggestions concerning that.

Thanks!
 
Throw a towel or three over the louder cabinet.

Or just get a stereo amp and matching cabs.

I'm guessing here, that you hear your rig and are thinking there's too much low end. Fix that with the bass knob on your amp.

Well, then the solution is simple:

-Get the preamp version that as closely mimics your current amp as possible
-Get a stereo power amp
-If you're using an all-tube amp, then buy another amp if you don't mind carting it around, and split your input signal between the amps

Any other solution is just going to be needlessly more complicated and expensive.
 
There are amps such as the Hartke LH1000 that allow you to adjust the output of two different cabinets connected to it.

I think all the options that you have with your existing equipment have been exhausted in this thread.

You can either:

1. Replace your head
2. Replace one cab
3. Add a second head or power amp to run the 2nd cabinet (slaved off the first head)
4. Try to adjust the eq to achieve the desired effect (you've already indicated that isn't what you're after, though)

If you really like the tone of your existing head, I'd think option 3 would be the best bet, though option 2 might be cheaper if you can fund the purchase of one cab with the sale of another.

Edit: I see one more slight variation was posted as I was typing this (replace head with preamp and stereo power amp).

Good luck! I have a similar problem in that I have an Eden D410T 4ohm and Eden 210MBX 8 ohm that I would like to run together (essentially a 610 with each speaker getting the same power) but I need an amp that can run below 4 ohms... if I ever do want to really do it, I'll probably pick up a standalone poweramp to do it.
 
Since all the suggestions keep going back to what I've already stated I don't wish to do. This thread may as well stop. I cannot state any more clearly that I do not need to change the EQ or add/replace an amp or cabinet. I have my reasons for wanting to control the volume of one cabinet (not EQ it). Just because the one I want to lower in volume has mainly lows, does not make it an EQ issue. But, people can't seem to get off that. So, let's call it a day. I understand people are trying to help and if that was what I was after they would be great suggestions. So, thank you for trying.

I really appreciate the couple of people who offered suggestions relating to the question I asked in my first post, how to adjust the volume on one cabinet only. The post with the link was especially helpful and has me moving in that direction, thanks! And ironically is the least expensive solution to all of those made.

Let's call this thread dead.

trouble is, those are the right answers; just because you don't want to hear them doesn't stop them from being the right answers. (trust me, you got answers from people who know more about this stuff than you or i ever will.)

at least until something burns up ;)

trying to pad down bass speakers sounds like a bad idea to me.

i guess you could make up a 200-watt L-pad, but i don't know how big or expensive it would be (or how hot it would get).
