Axiom Home Page Forums General Discussion Home Theater Velodyne SMS-1 Sub Eq Results

I know what you mean. I must have run sweeps for months and moved subs around, until I figured out just how my room influenced bass response.

The SMS adjusts filters above the crossover point because there is still output above the crossover point albeit declining by some 12db/octave (or more depending on the sub design). As you get more used to the device, I'd suggest manually adjusting all the filters rather than relying on the automatic feature since you can then move the filters by frequency and also adjust their breadth or Q. It will give you more flexibilty.

However neat it is, I've found the best approach is location, location, location for the subs then apply equalization as sparingly as you can, saving your biggest adjustment for those pesky peaks.

Ok, here are some new tweaks. Not as flat as it was, but kept the boost to 3db.

This was all manual adj. I can see where I could get totally addicted to adjusting this thing. There's alot to it, but man it's fun.

Before


After

Am I the only one that thinks the before response already looks pretty good?

Maybe I just have sqaure-room-envy...

That EQed response looks very good to me.

No, I thought the same thing.

Dana, I'd reconsider the concept of limiting the boost at the expense of not achieving the best correction. Whatever the capability is, use it.

The before response is not too bad, and I know it's hard to tell from the pics, but I have 9db spread from the high peak to the lowest dip, this is unacceptable. Believe me, when I hit button on the remote to listen to before and after, the after is much, much better.

John, I think you are correct. Could be my ears are burnt out from all the testing, but it seemed to sound better to me when I had the 5db and 6 db boost.

I'll have to give myself a break and come back to it.

Sounds like both of you have two or more subs. Do you need one of these for each sub or at least each sub channel or can one EQ multiple subs?

One SMS-1 can eq up to 3 subs. You can also daisy chain multiple EQ units (one for each sub), But unless one has more than 3 subs, I really don't see the need for having more than one SMS-1...IMHO

Dana

it can't eq the subs seperately, unless they have redesigned them.
