Getting Emo Ultra 10 & Behringer B2030P In Phase.

[Crescendo]

I got my new Emotiva Ultra 10 sub today, and I've been playing around with the controls to get it to sound as good as it can.

One thing I'm not sure about is the phase control. What is the best way to set this with the Behringer B2030P's? Should it be more to the lower end or more to the higher? I can't really notice it doing very much.

These seem to be popular speakers and subs here, so I'm guessing someone has this combo or something close to it, and can help me to integrate it with my system. This will be used mainly for music, and I don't want any really insane bass levels, as I don't listen much to the kind of stuff that produces them.

I have a small to medium sized room, and the sub is placed in front between my component rack and CD storage cube, not in a corner or far away.

Right now I have the crossover set to 80Hz, the volume one notch below the halfway point, and the phase one notch over the halfway point.

I understand it may take time to get it right, but any suggestions will help.

I'm not familiar with your particular set up. But I can comment on the Ultra 10...

Like most folks, I anxiously unboxed it. Sped to set it up. But then was disappointed with the performance. It took a bit of tweaking to both volume and crossover (phase was set to 0), some break-in, and experimentation with room placement. Sounds laborious, but it only took a day or so. But once I got it set, WOW. I was real impressed with the depth, precision, and quality of bass out of a 10", $325 sub. I can still hardly believe it sometimes.

Moral of the story: enjoy the journey b/c you'll be thrilled with the destination.

What did you ultimately set the phase level to? Where did you end up placing the sub?

Phase is still set to 0, crossover at about 60 and volume about mid way. It's situated to the side of my mains...sorta behind a chair. I'm not sure of the acoustics...I just moved it around until it sounded best.

Come to think of it, I should pull out the SPL to check it all out.

LOL that's pretty fast ! I got my ultra 12 3 weeks ago,and along with my DSP-3200 sub,it has taken me 3 weeks to finally get the bass right and to my satisfaction (I think) ,

I think the anti-mode 8033 dsp helped too.

but I can say that so far I am happy with the bass in this hard-to-make-sound-good-funky-house of mine,
time will tell though with the next few blu-rays,

but maybe not,since I am in pursuit of that illusive "perfect sound" and I am an endless tinkerer.

but for now,my bass is great sounding.

I should note that I'm using my Ultra 10 exclusively for music in a 2.1 setup. It's probably a little easier to set up a stereo rig than HT.

Remember that what someone else sets their phase to has bearing at all on the best setting for you. You just need to listen or measure your own setup - your equipment, your room, your sub placement - and see what sounds and/or measures best.

Generally speaking, most guides recommending leaving it at 0 for setting it up, and then switching to 180 (if you have a 0/180 switch) afterwards to test it out. For an example, read this:

You have a variable control, not just a switch, but the idea is the same.

The phase control setting for a sub is room location dependent, not equipement dependent. Simplifying it, picture a sine wave captured in time that can be slid back and forth in reference to your listening position. What phase does when turning teh phase knob is effectively sliding the output of the sub back and forth relative to the listening position so that you can adjust it such that you are at the peak of the wave form relative to the listening position. I hope this helps.

Try sealing up the port with a t-shirt etc as a trial. It should help getting the two in phase become easier. You can then use that as a point of reference if you choose to use the port.

An SPL meter should be used with setting phase, adjust the phase to where you get the most output....

This is similar to what I do. I place a SPL meter at the seating location and play a tone (MP3) at the crossover frequency and adjust phase to where there is the most output showing on the meter. Another approach (I'm told) is to let your receiver deal with it. According to one tech over at Hsu many mid-priced receivers will adjust subwoofer phase during the speaker setup process and will do so across a range of frequencies. I'm not sure if I'm 100% on board with that but those guys are pretty sharp. On the other hand I know dedicated subwoofer EQs like the SMS-1 do adjust phase.

Thanks for all your help. I've been experimenting and I think I'm close to getting the best positions for my set up, although I still can't really hear much of a difference when I move the phase around, unless it's all the way up, which doesn't sound quite right.

That SLP meter sounds like a good idea. Maybe I'll get one and try it out.

Thanks can I download the tone for my frequency response (Say 80Hz) somewhere?

Also, I have the Marantz SR-4023 stereo receiver with a single sub output. I doubt a simple model like this could take care of the phase problem for me as you were saying, but I'm not sure.

 

[sholling]

There are several websites with tones and sweeps. I just googled when I was looking. I'd grab a 60 and an 80hz as well as a ~40-100hz sweep. FYI the cheap rat shack SPL meter is all you need. What you're trying to accomplish is get to get the overlapping frequencies from the sub and speakers in phase so that some overlapping frequencies aren't being partly canceled out. The effect should be strongest at the crossover frequency.

I have a Marantz SR4000 with the same out put. Also interested in tuning the Emotiva Ultra subs with this type of receiver.

Thanks for any help.
