I am with you. My Noesis are almost the identical finish, so getting veneered subs would be kind of a waste also the fact mine will be hidden. I however love the standard finish on the PSA subs. Certainly very durable. The Triax does look very nice in the veneers, I want to see one in the black ash or black oak is it?

looks good...can you use 1/6 or 1/12 smoothing. 1/6 is suppose to be more in line with what we can hear.

That’s definitely up close, with a little tweaking I think ryan could spread the drop a little. Edited last post. What do yuh think bass?

WOW! look at those pics!

What kind of tweaking can I do other than running Audyssey? Moving the subs around?

Watched WWZ tonight, grenade scene was insane. I will try to graph it tomorrow. Several other really deep bass scenes too. I really enjoyed that movie, but I generally like zombie movies.

Definitely. In bed already but will do it tomorrow.

You might try spacing them out so they are more towards the end of the couches. By the looks of the graph I would say you are really close already.

Didn't have to re-run REW, was able to apply the smoothing to the run I had already completed, 1/6th smoothing

looks like to be +/-5db from your highest and lowest point. Still really good for pretty much minimal setup time. As mentioned in my previous post, you might try spacing them out a bit and see what that does. I dont think you will have much trouble tweaking it in at all.

I will give that a try tomorrow.

I guess I can turn off Audyssey run REW, move the sub(s) run REW until I get it looking better. At that point I could run Audyssey again. I would rather not run Audssey after everything I move the sub. It takes a while to run it for 8 positions.

Yes I would try to get the best response you can by moving the subs around in different positions like bass is suggesting. I’m not familiar with your room of course, but most rooms have their issues.. so far your first plot/position is the best so far. I have no doubt at all that the grenade scene was insane and your plot suggests it would be. Your at +-3 at about 12hz with no null first graph, just that little 3dB rise, (pfff) much better to have that than –3dB imo. Great for HT. Here is a graph presented in a different way that’s not so different than yours except it drops instead of rises, oh and drops like a rock at 14hz. It’s (19hz dip) has been addressed now with dsp, but it gives you a good idea of what I’m talking about.

What are your room dimensions? Pics? You may try posting this info in the REW thread. I have got lots of help the last couple weeks and today found the permanent spot for my two Submersives. There really is science behind placement!

Yea the grenade scene was freakin nuts! I am working on a house curve and I thought the roof was gonna fall in!

For the lower, left end of the graph, using the AVR menu, turn the subwoofer level down a dB or two. You'd be surprised how much you can steer a graph in this fashion. If you have multiple subs, find out which is the dominant subwoofer and use the gain control to steer the graph.

Check the distance setting in the AVR main menu. Changing this works for others. Doesn't work for our system but does work for others.

Another thought, before running frequency sweeps, allow the subwoofer amplifier a minimum of twenty minutes to warm up as this will make a difference to the stability of the graph.

(the above is based on personal experience with our subwoofer sound reproduction system)

For Triax owners remember you have the dsp settings button that changes the roll off. Remember to try both settings while your tweaking your setup.

Graphs and Text that follows from PSA website. From the measurement tab on the Triax page.



* 2 meter ground plane (1/6 Octave smoothing)
Program select button IN = BLUE
Program select button OUT = RED

^^^ +1 Good catch! Great room optimizing option to have. small, large, lossy or sealed.

A little food for thought.

Those running audyssey who want a boost down low should run audyssey with the program select button in. Then after the run, move program select button out and reset amp for effects to take place. smile.gif Many have done this with the subm with great results.

Can do the opposite to minimize compression down low at max output and keep a more linear response. You can see this on the compression sweeps between the two modes.

Its fun to see the first reports coming in. I am happy to see those getting the measurements going to get the most out of their new subs! cool.gif

I will try this, is resetting the amp simply turning it off and then back on? I'd also like to know where most Triax owners have set their gain.

Anyone plan on buying new subwoofer cables for the Triax? I am wondering if there may be any interference with the balanced adapter that came with the Triax. I was looking around for a new sub cable with both a balanced and XLR connections, but did not see one. I am sure they exist. Just curiosity here.

You got it, just turning it off and back on. Needs a power cycle for the change to take place.

Initially I plan on sticking with my current unbalanced cable and use the adaptor. My pre/pro (Anthem AVM20) does offer balanced outputs, so I may give that a try in the future, if for nothing else perhaps just to have a "cleaner" looking connection/setup.

I'm guessing this is mentioned in the owners manual?

Congratulations to all the new Triax owners. It's great to have another sealed, opposed-force subwoofer option available. I fully expect this sub to be a very strong competitor in this segment. It looks great too!

raynist,

A few things to help you get these sounding better and flatter.

First, you're definitely on the right track by deciding to turn off Audyssey and run REW during the sub crawl. May I also recommend to use no smoothing in all your REW sweeps - this will not only help you see the nuanced differences between positions, but also it prevents frequency anomalies from sneaking in without you seeing them.

Secondly, if you haven't been already, make sure that in REW, each new measurement you take gets labeled with positioning info so you can return to that position later & repeat the measurement(s) to verify.

Third, increase the volume on your AVR so that your sweeps aren't impacted by any outside factors. Starting at 90-100dB sweeps will help avoid this. If you do this, you'll prolly want to wear ear plugs. Also, do all of this with the program select button pressed IN. You'll change this later. You can also change the measurements results window to only show the region you're actively measuring - from 5-80Hz.

Lastly, trying odd combinations of positions may work, but also remember that you likely want to find the best response before Audyssey AND you want that position to actually work for you in your day-to-day life.

A few notable positions to try:

Opposite corners up front
Both on opposite middle of side walls
One up front and center, other opposite side middle wall.

Your third is going to really tie the room together, so keep that in mind. Potential best spot will be one up front & center, other two mid side walls, but that varies by room.

If you're lucky, you'll be able to get something like this with the above positioning and no EQ:



Then, once you've found the best spot, re-run Audyssey with the program select button on the Speakerpower amp pushed in. Once it's done, re-measure. If you're satisfied with the results, let the program select button out and proceed to victory over your room!

Best of luck. smile.gif

I am assuming it functions the same as the program select button on the speakerpower amp used in the submersive hp. I haven't seen the manual and further clarification from PSA would be a good idea. It would be easy to measure to see if it is necessary, and it won't hurt to power it on and off even if its not necessary I suppose.smile.gif

FYI, I had a pretty loud hum when I first plugged it in. I have my other stereo stuff in same circuit so can try to find source of hum in future. I bought .49 cent cheater plug and it is now absolutely silent. I called PSA Friday to ask about using one and they said no problem. They actually use cheater plugs when they are testing etc.
