Buying a sub

[CWM]

The 1,300 / 1,4000$ we are talking about is definitely one step out of my comfort zone! But that's how ate up I am with it right now. Go big or go home!

I do like it loud. Would like to be able to tell people to skip the theater and come to my spot. So I just used my spl meter and in order to reach 78 db I had to set the volume 80% and level setting +6 (max +12) them everything else is about -6 or -7 .is this ok?

Maybe I don’t follow you. All speakers should be at 75. Sub should be at 78. Or 80...lol
Also, putting the trims into the “plus” range can introduce distortion. I would raise the gain on the sub until you can get the sub trim around -5.

I'd also like clarification what volume reading you had as your avr doesn't have percentages of power (which aren't a useful way of measuring it either). Did you set your avr to relative or absolute volume (at least most Denons have that capability). Most of us here use relative when discussing each other's levels. Try this https://denon.custhelp.com/app/answers/detail/a_id/136/~/relative-and-absolute-volume-ranges

I'm trying here! Lol. Since my subs are my weak point currently. I have both subs turned all the way up currently and trim at +6 and master avr volume at 80 of 100 to get the spl meter to read 75! All others also reading 75 but with trim way in the negative. Did I do something wrong? Or is this just a result of in current house it's a really big open floor plan. Living,dining,kitchen all basically one room and weak subs

I did this using the white noise I think is what its called

I’d say your subs are just working really hard to get there. That’s a big space to fill and that’s just a matter of displacement. I’d just run it that way until you get the new one. Btw, what level did you set each sub at individually? Mine are like 71-72 separately and then combined equal about 75. Then I bump from there. I also use a minidsp to eq my 3 subs but we’ll save that stuff for later.
Do what you can now, and when that new sub gets there you’ll see what we’re talking about. I remember getting my first SVS pc12plus after using a 12” JBL for a few years. The first time I watched Peter Jackson’s King Kong was a revelation!!! I never heard bass the same after that.

that's the small sub/large room effect.

 

[William Lemmerhirt]

Ok, I saw that you have them both all the way up. I’d be curious about setting each one individually first and then both together.

 

[CWM]

Hopefully with this new house and what will be the movie room be around a 18x22 with angled ceilings will help alot. Picture up above. Also I agree. Small subs that are not the same/big room with lots of in and outs. Just happy i did it right.

 

[CWM]

I did measure them separately to make them match. Then did the trim. The poll is actually about 85 percent and other 100.

Whereabouts are you, @CWM

Ok. That’s good.

Before my subs where only doing 50 db. Everything else was 75 db. So doing this and now watching a movie. BIG difference. Crazy what I have accomplished for free just from talking to you guys

Nice work man. Just WAIT!!!!! You don’t even know..... mwahahahahaha

Yow that's not a good performance at all, seems your subs have a higher sensitivity level than most, too (seeing you've got gain at full and plus 6dB trim level on your avr).

When running your avr's test tones/pink noise (while running it) master volume shouldn't affect their level, or does it on your model? 80 of 100 is at near reference level in any case when using the absolute scale...not a percentage of power in any case, it's logarithmic so each + 3dB difference is a doubling of power. I use four very large subs in a 6500 cuft space myself, big rooms can be hard to pressurize

 

[CWM]

Wrong choice of words! Did not mean 80% of power. Just the volume number 0 being mute and 100 being max volume I had it set at 80. And while doing the pink noise level correction the volume up and down on my model does change the volume during testing/calibration. Sorry for the confusion.

Had to back the level down on my subs. The onkyo is popping and can smell. It cant hang. The polk psw110 is not popping but its maxed out. It cant hang either. I'm iv never heard a home theater before. Not a real one. But doing this I see why the subs are a big deal. Along with a good center. My cs10 is definitely struggling now. The monitor 70s are the only thing keeping up right now. Not saying that's because there so great. Just better than the rest of my speakers. Sad I guess. I think after subs next I'll start trying to pick good R/C/L speakers. Then probably a better AVR. One with at least 11 channels so I can do a 5.2.4 setup maybe even a 13 so I can do a 7.2.4! Then after all that add a 3rd sub.

the sub channels dont count as amp channels. so 11 channels will give you 7.x.4

 

[CWM]

So to be clear. Start off with buying 1 svs PB-3000 over two PB-2000. Also if I buy a 3rd ome down the road after all the other upgrades is it ok to do say a smaller same brand?
