Oh yes. I am ready to calibrate it and shake my neighbor's house.

The good thing is, very low freqency cannot be heard. It can only be felt.
So my neighbor wont know about the sound but his house will be shaking. biggrin.gif

Same thing here, the neighbors feel their house shake but can't pinpoint where it's coming from. They better pack up now because those were just tremors!

I had a friend with a bank of LMS5400 Ultra's that did that to his neighbor across the street! Evidently, the ULF in his concrete basement located HT was traveling through the ground across the street into his neighbor's kitchen where it made her crockery rattle LOL! You couldn't ear anything outside his house, but if you stood in one particular spot (an area maybe 2 feet across) on his driveway, you could feel the vibrations through your feet. He discovered that the bass made it all the way to her house when she mentioned her odd "crockery in the cupboards randomly rattling" and he recognized that the days coincided with his ULF indulgences. She ended up placing some rubber mats in the cupboards that insulated the vibrations enough to prevent any further rattling, so he never told her what the cause for the random rattling was.

Holy cow! Man I wouldn't of told her either, she'd hit someone on the head with a cooking pot! That's pretty incredible to do that as that would actually be earthquake status!

That is one awesome story! I rent a guest house on my landlords ranch out in the country. I am like 130ft away and haven't heard any complaints but there have been several times I have been worried. Like the hulk demo scene, and some of the ULF dub step songs from here on AVS. Dual SubM's...

So when you run your calibration, do you place the mic at the corners of your front yard too just to get an accurate reading? biggrin.gif

post #1663 of 3312
I just got the 2nd Triax in the house and positioned. One bit of advice for future Triax owners, it is to tall on the pallet to fit in my 4runner, each time I've picked it up at R&L I cut off the straps and we put it in the back. After those are removed there are no straps securing the box making it more difficult to keep together when moving. If any of you do it like this ask Tom to perhaps place a couple straps before strapping to the pallet. I used my Polaris to move it and straps to safely remove it from the Polaris but if you do it alone like I did you better plan well. Tonight I'll listen for a bit a give some feedback on one vs two.

I would help ya but I am a bit to far away. If you can't find anyone, you could always go to a local Home Depot and find a couple of laborers to help... Or you might try UHaul (ours always has laborers looking to move heavy stuff). Good luck with moving it inside. Another option is to see if the carrier will help you move it inside for a little cash. I will be using a little furniture dolly http://www.homedepot.com/p/Milwaukee-1000-lb-Capacity-Furniture-Dolly-33700/100057209?N=arxn#.UoUjdPnrwmU . Once you get it on this you might be able to move it by yourself. We will be putting a sheet of plywood up 3 stairs to push the dolly up to get to the house level and then it is just roll it and lift it over the door threshold.

That's the same dolly I have, except I filled in the open space with pieces of wood to give it a solid flat top. Once on the dolly it was easy for two people to roll it up the ramp I made to get into the house (1 step). smile.gif

Sorry I wasn't clear. redface.gif

I had two people helping me. Turns out two of us could have handled it since we didn't have to do any dead lifting. With the Triax weighing 100lbs more than me, there's no way I could have done it by myself. eek.gif

Ooh... I thought you were just sliding it off the pallet onto your dolly (no dead lifting). I am glad I have a friend coming over to help! smile.gif
post #1669 of 3312
Looks like the parts are arriving and the backlog is being cleared. I received an email from Tom updating that my 6KW version would hopefully be built next week. Drivers may be there, but amps are being shipped it on an expedited basis.

Problem is going to be doing a sub crawl. Wonder if the electrician would be willing to setup an extension cable from the patch panel for the 220v circuit.

Yes, you're right, no dead lifting. While the Triax was still in the box base and padding, we slid it directly from the pallet to the dolly. Once in the room, we slide the Triax, still in box base, off the dolly onto the floor. At that point I cut the tape holding the corners of the box base to flatten it so we could slide the Triax off the box onto the floor (the foam pads were still under the Triax). After that we slid the foam pads out from underneath the Triax, then removed the plastic wrap and thin foam wrapping (we had to tilt the Triax a little to do this).

Even without dead lifting, you'll want some help.

I hope this isn't confusing.

I wish I had taken step by step pics, but I was too excited at the time and didn't think about it.

TY, R & L helped me carry each of my other subs to the door, they said they cant step a single foot into the house, im just worried about lifting it to the door, its 4 steps so its not alot, but lets just hope we can lift it up.
post #1672 of 3312
You guys could ask and pay the delivery guy to help you move the Triax inside. That is what I did with my Orbit Shifter LFU. I paid the delivery guy $10 to help me carry it up to the second floor of my house.
post #1673 of 3312
I forget who posted it, but moving straps seem to be the best answer to move the Triax. If I am to do it again which I will when my theater is complete, I will be using moving straps.

As a reminder, I do not have any EQ, automatic or manual except for a single PEQ filter in my pre/pro (Anthem AVM20). Also, I've not had a chance to experiment with adding my old SVS cylinder sub into the mix, besides, given its size and shape I'm not sure I can put it anywhere that would be visually acceptable (system is in living room). LP and sub location is pretty much fixed. Right now there's no money to add or replace equipment. Given all that let's assume I'm trying to get the best from my Triax given these limitations.

Here's my graph for the crossover settings:


Here's my graph for distance settings. For reference the physical distance from the prime LP to the center of the Triax is 10ft, and from prime LP to L&R speakers is 8ft.


For now I settled on these settings:

HP filter 90hz
LP filter 80 hz
Sub Distance 12.5 ft

Looking at the crossover graph, it looks like the best HP filter setting is 100, but I start to get localization at that point, so 90 seemed a good compromise.

Oh, and graphs are unsmoothed. wink.gif. Also, you'll noticed the graphs are zoomed in a bit. The response below and above the frequency limits converge so I didn't see the need to include those areas.

If the graphs are too hard to read I can take images of the separate curves. Also, I can email mdat files if necessary.

So am I on track or should I change my settings?

Thanks. smile.gif

I should explain how my pre/pro handles bass management. The HP filter is only applied to the mains, center, and surrounds (btw, I can set different frequencies separately for the mains, center, and surrounds). It dictates at what point to roll off bass to these speakers. The low pass filter is only applied to the sub; telling the sub when to start rolling off higher frequencies. If I were to turn the HPF off, the mains, center, and surrounds would be operating full range. As you can see my Anthem AVM20 offers some flexibility in tweaking the crossover region (slopes are not adjustable though).

Also, my pre/pro offers two independent speaker configuration modes; Music and Cinema. Within each mode you can set speaker configuration anywhere from 2.0 to 5.1. Also, bass management (HPF, LPF, distance, etc) settings can be different for Music speaker configuration and Cinema speaker configuration. Currently I have Music set up for 4.1 and Cinema for 5.1. Currently I have crossover (LPF and HPF) and distance settings set the same for each mode. Each input can be set to use either the Music configuration or the Cinema configuration. Of course inputs I'm using for video are using Cinema, and inputs for music only are using Music.

The Triax amp has no crossover filters, only gain and DSP program selection (button in rolls off steeper than button out; it's kind of a room gain compensation switch). The manual suggests button in for rooms <5000 ft3 and button out for rooms >5000 ft3. My space is about 5500 ft3, so I have the DSP button out.

The measurements I took are only mains + sub. Since my laptop doesn't have HDMI (I'm using the 3.5mm plug analog output to my pre/pro) I'm not sure how I could measure all 6 channels at once.

My mic is a UMIK 1 I bought directly from miniDSP. The calibration file shows offsets down to 10hz.

The reason I limited the graph at each end is that the response outside those limits converges. Different filter and distance settings don't seem to impact frequencies outside those limits. That said, I can either repost any of the above graphs (individually, or as a group) with an expanded frequency range, or I can take a new measurement when I get a chance with the current settings and an expanded frequency range.

Another clarification, I not interested in getting the best I can, given the limitations mentioned in my prior post, across several seats, just the prime LP.

smile.gif

PS - Just watched Star Trek Into Darkness. Freaking awesome! What a ride the Triax provided!

I posted this several pages ago and was hoping to get feedback from some of our other sub gurus here while I wait to get a chance to take more measurements requested by Nube (thanks for your responses Nube!).

Any suggestion which filter and distance setting I should be using?

Thanks. smile.gif
post #1675 of 3312
As I previously mentioned, I would hook up the 16-46 for smoothing purposes. Try it and see before you start adding filters to flatten the response. The distance setting is more trial and error the anything...play with it and measure. btw sorry for the late response!! I did get your PM and replied but realized later that it didnt send. So I figure that I would just reply here.

Hi stm69,

you ordered the 6 KW version of the Triax, does this mean you are about to own the international version with the amp capable of using 240V input? If so, can you tell me how much the price difference is between the 4 KW and the 6 KW version? PSA's website doesn't state anything about the 6 KW version and my questions about the difference in pricing haven't been answered yet by Tom.

Don't remember exactly probably $2-400++ more, along with needing another circuit.

Hey, you did see where he said he prolly had no place for the SVS in his room, right?

Thanks for your answer. Just for my interest: According to your profile your from Cincinnati, so you wouldn't need the 240V version of the Triax. Tom also stated the difference in performance between the 4 KW and the 6 KW version won't be much more than 1 Db in output, which doesn`t really make a big difference considering we are speaking here of barely audible advantages between let's say 135 and 136 Db inroom. In return, you have additional costs for the amp and the 240V circuit plus additional work for installing the circuit. So the following question seems obvious: Why did you order the 6 KW Triax instead of the 4 KW version?

Thanks basshead.

When I get a chance, I do plan to see what happens when I throw the 16-46 into the mix. As Nube mentioned, I really don't have a good spot where I can leave it, but at a minimum it would be educational.

Regarding the distance and crossover filter settings (my pre/pro has separate HP and LP filters), did you get a chance to look at the graphs I posted? Looking at them I'm still not sure where I should be setting things. If you get a chance I would appreciate your input on which settings look best. smile.gif

That's correct. Still, I would like to see what effect it may have, if nothing else, just for the education. smile.gif

Sorry I haven't gotten those additional measurements you requested; too much to do, not enough time. wink.gif. I will do it when I get a chance.
