I try this now, but I was in a chat session with PSA when I was posting this stuff. They guy from PSA thought the Sub EQ in my Denon X4000 would take care of that. He also asked me to rerun the REW with just the speakers and no subs. Doing that now.

Cool.

My denon 4311 has that too and it really helped.

Wow, I just went to rerun my tests and this graph was center channel only.


Been playing for about 5 minutes. For some reason when I run REW it is only using the Center Channel now. Every since I recalibrated with audyssey

Good Evening,
Long time reader, first time poster. I got my PSA XV15SE yesterday and I have been playing with it tonight. I have a couple of questions that I know I have seen the answers posted, but yet can't really find them when I am looking for them.
First, when I run Audyssey, it sets the cross over on all of my speakers to 40 hz. I have all ARX speakers: A5 fronts, A2RX-C center, and A1B surrounds.
1) Should I go back in afterwards and manually adjust to 80 Hz?
2) The level setting for the Sub sets to -4.5. I recall seeing that a lot of people run their subs "hot". So, do you adjust the level from the AVR up or adjust the Gain?


I moved the sub closer to the corner, which helped a little, as I had it about 3 feet away from the front corner wall. Now its about 8 inches or so away.


Any input for a beginner would be great.

1 ... manually set speakers to small and try 80 or 100 hz out...


after moving the sub re run aud.. -4.5 is not bad .. run it hot by bumping up the level in the avr but not passed 0 or so.. a setting by aud at -9 is better..


enjoy the sub..


cheers..

Yes, set all speakers to small/80hz.

If you want to run your sub hot, adjust the trim in the AVR not the gain on the sub.

you want to manually set all speakers to small... not large.. so you can pick your own crossover .. eg 80 or 100hz..


large will run the speakers full range.. small will work better with the subs


cheers

I can't set the speakers to "small" on my Onkyo receiver, it just asks about what Impedance to set them to, and that's about it besides the crossover settings.
What about when Audyssey asks to set the Sub DB setting to 75 at the beginning. I have to turn the gain down to at or slightly below "noon" to get to the 75 db that it's asking for before the self calibration starts. Should I ignore this and leave it at the 1 to 2 O'clock setting?

For some reason the computer itself changed out of a 7.1 config so I had to redo it's settings.

I am pretty much giving up. I moved my subs all around the room, moved my mains backwards, forwards, sideways and laying down. The dip was best back towards the wall. I just need some any more suggestions on what to try. I have heard about venting risers, and what about my bass traps, should I take those down. I can't obsess over the lack of perfection and that is what I will do so I need some other suggestions.


P.S. I read the distance tweak and that didn't make sense to me. I did turn my phase nobs with the REW running and they were loudest where the phases set with Audyssey.

just following up.... I started with a psa xs15se paired with my klipsch sub-12 and was happy but wanted more. I had a tough time tweaking them together (not a huge surprise). I then moved to a xv15 with my xs15se and was pretty happy.


i'm now sitting with a xv15 and xv15se. WOW. I do only watch movies and game but whoa........ THIS is what I was looking for. when people talk about feeling bass in the chest, yup, this is it. my room is approx. 3k cu ft. Lone Soldier and Max Payne were awesome.


In regards to Audyssey, I now keep DEQ on (wife and young child at home), listen at approx. -20db, run the subs 3db hot. settings are perfect for my tastes.


Just sharing b/c tweaking at first can be a pain, trying to give others a starting point. PSA.... made in the USA, best customer service, digital amplifiers, crazy bang for buck... not sure why you'd go anywhere else for BASS.

Basically you do a sweep from say 1-300hz with just the sub, and then do one with just the mains or center (I did center). View both graphs at the same time and notice the crossover area. Next do a sweep with the subs and center (or mains) and compare that to the separate graphs of the subs and center. If the sweep with subs and center at the same time is lower in the crossover area or has dips the other combined graph doesn't you need to follow the instructions on changing the sub distances.

On my Onkyo (818), setting a crossover amounts to setting the speakers as small, so you should be OK there.

My understanding is that it's OK to set the subs to 85 dBs or so during the Audyssey calibration (the gain on my XV15s are set at 2 o'clock). Audyssey will lower the level for the sub channel accordingly. The only thing to be mindful of is that you want to avoid hitting the minimum limit of your AVR's trim level for the sub channel (e.g., you don't want Audyssey to set your sub trim to -15 if -15 is as low as your AVR will go). I doubt that would happen if you start at 85 dBs, but it's something to be aware of.

I did separate subs, each one by itself then together, the mains together, and the center alone. All of them had the dip in the 70-80Hz area. I tried subs apart in the corners like the link to my HT. I tried the subs on each side of the CC, I tried both subs in the front left corner as one giant sub. I tried 1 sub left front with the other right back. I tried the left sub a third of the way up the front wall and the right sub front corner, I tried the both subs front corner with the woofers facing front and back. I tried both subs front corners with the woofers going side to side. I tried the left sub front to back with the right sub side to side. Every single position had the dip at 70 and 80. The only thing that ever changed was the distance of the dip. I just don't know if there is a solution.

After all this talk about phase I figured I would give it a go on my dual xv15se's, and what a difference it made! I had experimented with this with all my previous subs and never heard a difference, so I sort of thought it was non sense - man was I proved wrong.

In this post here I do not see any major dips....what is wrong with using this setup crossed around 120hz? 99% chance you will never get a razor flat curve without room treatments and some form of external eq. Honestly the graph does not need to be razor flat...just as long as there is no major nulls you should be good.
