4 uls-15 mk2’s vs 4 pb-2000’s

What you need is a way to measure your system if you want to optimize it. That means you need a mic. You can kind of do that if you have a good smartphone and the right app, but I wouldn't trust that as much as a decent mic. Anyway, if you like the sound and it sounds good to you, you don't need to fret about it too much.

If you are going to add more subs later, and you have freedom of placement for these subs, ie. there are many different places you can put them, its worth getting a mic and testing different locations to get them in the best spots. With 4 subs and the right placement, you might be able to get the frequency response so nice that there would be no need for any EQ whatsoever. EQ might actually hurt more than it can help by amassing group delay.

I have a good smartphone don't want to buy a Mic just yet. What is a good app I can use?

I'll get the Mic later paying bills this paycheck but like @Reckel this is something I want to learn how to do so very interested in learning this. If you don't know a good app off hand what should I be looking for in an app

 

[shadyJ]

I don't know specific apps, but I have heard there are some reasonably good ones out there. I will ask around.

As you can see by these images, two different phones, two different roll off points. One rolls off around 200hz, and one rolls off around 70hz. Even though these phones are a little older, their main job is to focus on voices, so even if the mics are better, I still think they’d be useless in subwoofer bands. I’m not sure what frequency the pink noise is centered at in an avr for subwoofer test tones. Using a phone mic will likely pick up the higher frequency harmonics well enough to get in the ballpark for level matching, but I seriously doubt their effectiveness for any critical measurements.

Obviously I need rew when I get the mic correct?

Yep ya do!
We’ve talked about this before so you know where I’m at. But ignorance can be bliss. If you’re digging the sound, maybe just run with it for awhile until something really stands out to you.

I would set the level on the subs to 9 o clock, and see how close the AVR can get to that in calibration (that is, if I decided to let the AVR calibrate).

What are your thoughts on using the new D&M Audyssey app to only apply Audyssey below the Schrodinger frequency?

Yea I think they sound awesome. I guess what is bugging me, which idk why, is after running ypao it sets the subs at -2. They’re each level matched to my seat at 75db but like I told you the gain knobs are just under 9 o’clock n little above 9 o’clock. Guess I thought they’d be up a little higher. Two of my bics were at 10 o’clock n other two were just under 11 o’clock but I really can’t compare those to the 3s.

 

[Reckel]

I didn’t know if I should be going for a certain range after ypao, like -5 to -7? But if I do that, checking them from my seat they’re each running 5db or more to hot

Id be interested in that I have the Denon 4400H I think you can get the app for like 20 bucks. But I just need to bite the bullet and get a Mic. Any suggestions on where I can find one?

Any good links to Amazon perhaps?

I would rather approach the problem using as little equalization as possible, and that means multiple subwoofers. If there is some problem that subwoofer quantity and placement can not address, then I would turn to Audyssey. I have a friend who has done some acoustic work, and he has shown how all these filters can stack up.

Think they are talking about miniDSP UMIK-1 which is a usb mic for a computer. The REW software is free but you can send a donation.

The mic is about $12 more on Amazon than directly thru miniDSP.

This just makes graphs. To actually make changes using the software you need the miniDSP box. They have several for subs that sit between the sub LFE rca. There is even a big box for each channel between a surround processor and every amp channel RCA cable.

Again, I don’t have the mic but am going to soon to at least measure my rooms.


Edit: Oops. You meant a Denon mic...

Nice setup!

Thanks! The self gift that gives back everyday.

Yeah Audyssey on my Denon nailed my subs they sound so good I haven't even wanted to run them hot. I think I'll just go that route you talked about. I hate eqing all this crap. Besides you know I want to go to quad subs next year anyway.

Hey on a side note I hurt my back today so I'm going to be stuck at home for a couple days. I'm going to rerun Audyssey and run the 4000's in 3 port mode for awhile. I like them in extended mode but since I can't barely walk right now and have nothing better to do I thought I'd enjoy them in full range and see if I notice any difference. I'll hit you guys up If I can tell any difference.

I forget, what is your ratio of music to HT?

Sorry to hear about your back! I bet those good deep vibrations will keep it from getting too stiff while you are recuperating! Might check with your accountant about deducting your subs as a medical expense (if only!).

My vtf3s sound awesome but can anyone tell me why when I lean forward some in my seat the bass sounds even better? I’m really only hearing this when listening to music. I have two rows of seats and usually sit in second row. I’ve been measuring from my main second row seat n tonight I tried measuring from all the seats. It sounds the same even if I just measure from main second row seat
