Speaking of grill covers, hey @Gooddoc , you get some glue to keep those bad boys on your m2's?

You may find that the response is better with the combo a little ways in from the side wall, or perhaps better right up against the side wall. Doing this configuration will allow the ability to experiment a little with what sounds best to you.
Thanks.

That is probably the route I will take.

If they end up being higher than that should i angle them down just a bit?

I wouldn't be able to explain it well.

You can start watching from 45:30 in. He starts talking about Class D amp then and goes into Tubes...

I will vouch for it. Great great amp for sure. Small footprint. Pretty cool looking too I know his affinity for tubes, so in the Tga-7401, he put a switch on it to basically make the first 5 watts from the main channels sound as if it were a tube amp. It is basically a 5ohm resistor in-line that introduces the distortion one gets from tube amps that makes speakers appear more "warm" My biggest regret is I never even tried it....

You certainly could, but if only the difference of an inch or two, it won't likely make a difference at the distance you will be sitting.

Lol, no. It's not like they spontaneously fall off and I never listen loud enough at home to blow them off. It's only a demo issue and I know to take them off first . At Asim's I left them on because I figured it would be funny to have them blow off for dramatic effect .

^^ Actually beast, it's a 1ohm resistor on the "Current Source" outputs (L&R or LCR depending upon the amp model). I did try it out and found it did very little (as you would expect) but it was a feature. Besides being a very good engineer, Ol Bob was a marketeer.

I owned several Sunfire amps and every one of them did the job. Lot's of power, cool running and dead silent as am amp should be.

My bad....1ohm resistor, up to 5 watts I guess. not 5 and 5.

While you are at it, care to offer up any more opinions on auro vs atmos DSU? Which are you really liking more?

I spent a good amount of time with both the Auro and Atmos demo disks last night. Even though I positioned my speakers for an Atmos 5.1.4 ceiling mount, both formats work well. Based mostly on the quality of the demo material, Auro-3D makes the the most dramatic and appropriate use of the height channels IMHO. The Tractor demo is the most impressive surround sound demo ever and on the Auro Tractor demo, the ambient sounds and then the tractor moving from behind and then passing on the left is simply amazing.

For music, I really like "Whoop Ass" on the Auro disk and the Enrique Iglesias Music Video, "Bailando" on the Atmos demo disk is just fantastic. Really, I think the object vs 3D channel based approaches taken by Dolby and Auro respectively are both very good and which is better is mainly due to the recording itself. If Auro catches on I'm definitely adding another JBL 8340A as the VOG channel. The JBL's can keep up with the JTR's and the design is perfect for my room's 9' ceiling height. I would love to hear what 4 or 5 Slanted 8's could do but at $5.5K just for the speakers it was a little too risky.
Hindsight, I think it would have been worth it just for the timbre matching alone but again, the JBL's sound very good so no real regrets.

I'm anxious for someone to come and hear what I'm hearing as it is pretty exciting. Perhaps, the biggest difference maker in M/C audio since the intro of surround sound. It's unfortunate that so few will get to experience this outside of a commercial Theater. The intimacy of a Home Theater really allows the formats to shine and they seem to be relatively tolerant of slight speaker position anomalies.

If I sound (pun intended) excited, it's because I am. Of course, this is with the "Sunday Sample" demo disks. I also ran the Scuba Steve Bluray demo and the standard 5.1 and 7.1 lossless audio tracks sound noticeably better with the Auro-matic and DSU upmixing formats. That said, the big win is with source material recorded in the Auro/Atmos formats. I seem to be in the minority but for me, the DM $200 upgrade to Auro is a no-brainer if for nothing more than the ability to play some very cool demo material and, Auro-matic for the rest.

This is great. Is there an auro demo disc or something you are talking about with the tractor thing on it? I have the atmos demo disc headed my way thanks to a forum member. Currently I only have the two front ceiling speakers installed, as I had enough components laying around that I could build a full coaxial for the fronts, but I need more stuff to get the rears going. I have really liked what I have heard so far from the initial setup I have right now, but one thing became apparent pretty quickly: I have to get my side surrounds down to ear level. Right now they are mounted in a triangular box mounted in the corner of the wall and ceiling, aiming 45 degrees down, but at this point, they are now too close to the front heights, the separation of the channels would much improve the experience I think. The plan is to bust out the wall and get them down to about even with the top of the couch on the front row, so slightly above ear level. Shouldn't be too difficult, but requires build a box into the wall in between the studs, using that space to prevent the box from coming too far out into the room which is already a little too narrow at 12'.

I just emailed Auro, mentioned that I had purchased the upgrade and they Fedex'd it to me fast. Some interesting vids on Youtube re Auro-3D.

Yes, channel separation is key and lower side surrounds is a good thing if you can make it work. I don't think you need to be at ear level as slightly above will work just as well. Mine are maybe 1' above ear level (the coax on the Triple 8-LP's) and I won't be moving them as there is plenty of separation between them and the Heights. Adequate room width and height is helpful and I am lucky that I have enough of both to make it work (to the extent it does ).

Since you are building your own, it is definitely worth a try IMO.

Yep, that is about what the plan is. The current couch and loveseat have a little higher backs than a normal theater chair, so they will be slightly above that so as to not be impeded by others sitting in the same row. I am getting stoked. I will likely call in for the upgrade this weekend. I gotta get some more dang speakers too!

So, Rob, how much separation do you have between your T8's and the JBL's? In feet? And do you feel this distance is perfect?


This is one of the things I've been wondering about but can't seem to find any specifics on.
