This is my feeling joshjp. Another room and all your problems may disappear. The number of mode is fixed base on room dimension. This is one reason to consider another room.

The above reads like somebody isn't using room measuring gear. confused.gif

Without room measuring gear, there's no hope.

I highly doubt its his room...he went from dual empires, to a XS30, to a XV30, then dual XV30's, and finally a Triax. Dual XV30's only netted him 105db and I think he mentioned right after he got the Triax it peaked around 113db. I do not care how bad the room response is, his room is small enough that all of those subs mentioned above should hit peaks way above reference. Fluctuating voltage is no good, I still say the subs were starving for power. I can hit 128-130db with 3 XV15's across the entire room except for one small spot directly in the center. This is a 1977 built home with a 15amp circuit...my can lights dim on peaks, I am sure there is more output to be had if I addressed the situation and put a 20amp circuit in. However there is no need for anymore output in this room as the windows and walls are taking a beating. When the time comes I can build a custom theatre, dual 20amp circuits with reinforced walls will be a priority. Can you put 4000watts rms on a 15amp line, hell yes, but you are not going to extract all of the output the sub has to offer before the amp goes into clipping.

And this fact, pisses the rest of us off.

Line voltage in many American homes is between 126-115 volts depending on where someone lives. In the vast majority of instances this is sufficient. I do concur that the final answer will be an ah ha moment for all of us.

BeeMan it sound like your are in bass heaven!!!

Basshead I know the two empires should have been enough to impress anyone.

I run my subs off two dedicated 15 amp circuits which works great. I have the two Chase SS 18.1's on one outlet and the Chase SS 18.2 on another outlet. So far I have not dimed lights or tripped a breaker. My line voltage stay at 120-124 volts. I had the 2nd 15 amp circuit put in in Oct.

What gets me is that when he tries to push the Triax on some bass heavy movie clips, the subs doesnt seem to be flexing all the way and sometimes is clipping. Ive played the same scenes much higher than what hes attempted and they dont clip and flex the full 3 inches. That means somehow the subs hes running are being restrained whether its not proper signal or voltage or maybe its a faulty piece of equipment, cable, setting, ect. Sounds like from the graph that his room is fine and we can assume the sub is also since theres been several different ones used in the same scenario. If it was me I would start eliminating done the line, cables, Receiver, ect. Until the hidden culprit has been identified. biggrin.gif

Hell Bee most setups should be able to do that here. I basically have the output of one Triax on paper. 113db is around -18 on my AVR...the subs are not even working at that level. Your dual FV15HP's should do similar with alot more below 16hz.

I just don't see it this way. I believe you have a unique situation.

In a bit, when the subs are broken in and I'm up and running on XT32, the way you suggested (run the system up to max SPL and then back off 3dB), I'll do some max SPL measurements so as to see, what's what with what.

Your being to humble Basshead, we all know that your output would send most running down the street! eek.gif I like seeing a setup such as yours properly tapped into full potential and so well intregrated. I hope to be at this point soon myself.

In 2 port mode the FV15 hits a peak of 119db @ 50hz...add 6 db for in room and another 3-6db depending on placement. Being you have one placed nearfield, I am willing to bet 127-128db @ 50hz is very possible.

Not really...for 25xx.00 I would expect every bit of that unless your room is massive. Look at the Triax cea2010 numbers, Dual FV15HP's should be real close to a Triax in output.

Guys im finally trying out REW! Um I have the mic hooked via USB to the laptop. Im on the first part when you calibrate the mic to the soundcard of the laptop? When I run the test tone the volume on the input level isnt showing and it wont let me match the levels, what could I have set wrong?
post #2776 of 3312
When i do the calibration sweep the volume wont go loud enough for the input to be able to match with the output, it stays real low

Did you enter all the basic parameter settings in the Guide I linked you to? You might want to head over to that thread
http://www.avsforum.com/t/1449924/simplified-rew-setup-and-use-usb-mic-hdmi-connection-including-measurement-techniques-and-how-to-interpret-graphs

There are numerous little parameter settings in REW and Windows that can cause problems (hence why they say the learning curve can be a little steep with REW vs say Omnimic or XTZ).

Volume level?

Playback levels?

Thanks, I'm going to read that thread to see if I can figure it out. I know I probably have something simple hooked up wrong. I have the omnimic hooked to the laptop via USB. I have the phono jack cable hooked to the head phone output on the laptop with the other RCA ends going into the receiver. When I do sweeps the volume going through my speakers is very low, even though the REW volume, receiver, and laptop controls are all maxed. Man it's confusing to what I might be overlooking lol
post #2780 of 3312
This is where I think I might be wrong, where on my receiver should I plug the laptop to?

Black.. Does your LT have a HDMI out? If so that's what I would do. LT HDMI >> AVR HDMI .
post #2782 of 3312
Plug it into the aux in rca inputs in the front panel

Actually the laptop only has a headphone connection eek.gif

Lol let me try that, I had it plugged to the back of the receiver

The test tones are still faint. If I unplug the cable from the laptop, the laptop plays the tones loud. When I plug into the receiver, the tones are weak going through the HT speakers even if I max out all volumes. I wonder if the connection to the laptop phono jack end is the right size for the laptop? It has a long tip but its almost like its not making the right connection or somehow the laptop isnt allowing full volume to the receiver
post #2786 of 3312
Heres the end of the cable im hooking to the laptop, and the headphone output on the laptop and the front input on the receiver



post #2787 of 3312
Does the laptop inboard speakers play any test tone when the cable is plugged into the headphone out?

You might need to go into the control panel and turn the volume up or into the correct output setting

Make sure in REW you use the java setting as well I believe that can effect it sometimes

Thanks ill check that! If i disconnect the headphone jack the tones play through the laptop speakers, when i plug it in theres no longer sound from the laptop and you can hear it through the HT speakers but its faint. Im going to try plugging in some actual headphones into the laptop to see if I can figure out the volume problem. I maxed out the volume levels under control panel but didnt see any headphone volume controls. Maybe once I find this itll fix the problem. Man I got everything else ready to go so as soon as I figure this out ill finally do some sweeps! biggrin.gif

On our receiver, with the AVR switched to aux, I had the volume on the AVR turned up to -5dB. Do you have the volume on the AVR turned up?

We have the volume turned up to 100% on the computer out.
