Good stuff, Josh!

Are these meeting your expectations or would you do something different/change something?

Bro...They can't all be Roy Rogers films.

Or Gene Autry!

Sold!

Any one interesting in getting into immersive audio?

I've got an item for sale.

In like-new condition. Includes everything with original box. Trading up on this 6 month old unit to the Yamaha CX-A5100. Works great, sounds great!

Product information: http://usa.yamaha.com/products/audio...a3050_black_u/

Only six months old. Has all the modern bells and whistles including 7.1.4 support for Dolby Atmos. DTS:X update due in March 2016.

Still goes for ~$2,000 new. Asking $1,400 shipped to the lower 48 states. Accepting Paypal, no fees required.

Because they still have not installed proper sound monitoring in the studios.

That is the only reasonable explanation for this.

The sound designers and mixers work with what they hear, and if they can not hear or otherwise experience it, it will only be noise appearing on the spectrum analyzer (if the spectrum analyzer even shows what goes on below 20-30hz.. in a studio I have visited it does not..).

This is EXACTLY why.

Yup. It's got the good but fairly low level throughout. Some good effects. Turn this one up.

Haha. Would have to be quite a tall riser had you were interested in the ass-fire setup.

Yep. That's why I would go 10-12cuft at the least.

I'd go no lower than 8cuft (also slightly depends on split-coil or overhung version) but I'd shoot for 10-12cuft at the least.

I still enjoy Phantom a bit. It's fun! Clones and such are much harder for me to watch. Gotta do it with a rifftrax or something.

Sorry but both Phantom and Clones will eat New Hope for breakfast when it comes to bass.

Same reason why I cheat and use all twelve of my 2226's as one single subwoofer in addition to the rest of the 18's. Punched that shit right up! Lol!

He does now, yes. Four more Mackies added to his system for Atmos.

Not really. I saved one graph from EoT but with all the things going on that day I did not properly document your system with the app.

Though I will say... the single reading I took was heavily clipped which isn't good data but it simply means "holy shit!". So... you're doing pretty good.

And this room, so far, is my idea of sensible.

Takes all kinds.

I'd be interested in your real-life reaction to using Vibsensor with your frequency response graphs.

Great. Now repeat that on somebody else's system similar to yours like Adam's.

Paul, get a video of your dad's mind being blown and his world turned upside down.

Seriously. Vibsensor measurements changed everything. Measuring frequency response is only a part of the experience, what the mic hears. Vibsensor is the other half, what we feel.

Try it out. It's free.

I had a similar experience in my room a month ago. Was doing some EQ revisions with my sub system and did A LOT of tinkering. So I ended up with a totally flat response to below 15hz with no EQ filters at all. I was astounded. But... even though I had a perfect response at the seat, something was missing. Maybe it wasn't loud enough but something was off, way off. Well...something was off. Almost all my subs. Had forgot to re-raise the levels for all but two of my subs so it was just the two nearfields going alone. It was still loud actually (not surprised with four 18's) but even with a totally flat to below 15hz response the experience was just "meh" at best. Anyway, found out a couple days later and fixed it. Now back in business!

But anyway... frequency response is super important, obviously but it's not everything. Working with the Vibsensor app and taking measurements of my own system was a huge eye opener to me. I found that this is the missing link in the puzzle to situations like you experience with your friend and that MANY of us deal with from room to room, system to system. If you're not using Vibsensor with things like REW, Omnimic, SpecLab... then you're not seeing the whole picture. It's time to get with the times and evolve, folks. Measuring just the FR alone is like living in the dark ages.

Wait... what the f*** does this have to do with this awesome driver?

My bad. Carry on.

Hehehe, this is so awesome.

This is why I've got twelve JBL 2226's running in tandem with just as many subs. Can't blame the speakers for any lack of midbass.

Bosso - we need to get you hooked up into the world of Vibsensor. Frequency response is not everything.

 

 

Clearly this isn't a type of driver for every app or everyone. Thankfully we have a large selection of choices to fit everyone's personal preference.

Feel like I've said this a lot lately but.... the best value (sub driver or bass system) does not mean it's the "best".

It takes all kinds and I like it like that. Who all wants to own the same system? I don't.

Page 14 and 15 will blow your mind.  Looks like there is enough theoretical room to do 24.1.10?

 

Time to sell that car.

 

JSS

Yup. I'm familiar with all the consumer and cinema level Atmos documentation.

Up to 24 ear level speaker locations and 10 overheads for the home version.

Nope. The SRT stays.

Haha! Thanks guys.

Only reason I said 'not enough speakers' is that if anyone on this earth is going to have true 64-channel cinema ATMOS in their room, it'll be Scott...

 

JSS

As we discussed at Brandon's... there is no more room to expand for current home Atmos. There is only one option, a $30,000 option at that. Buy a Trinnov Altitude32 which would support up to 32 outputs and handle it in full with Dolby Atmos.

No thanks. I bought a car instead.

But in actuality I am pushing the envelope with current Atmos. It can only go "up to" 7.1 + four overhead speakers right now. I'm using external processing to get another two "channels" and it works but further complicated the whole setup. Really it is set-and-forget so it's just an additional thing to do.

Using this I run a 7.x.6 speaker system.

"Cables

 

copper ones"

 

LOLOL!

 

Um, yeah Scott, think there's room for a few more speakers in there, I can see a couple blank spots on ceiling and side walls.

 

You happy with the Yamaha? I'm looking at picking one up.

I know, right. I need MOAR!!!

I love it. I has a couple things that bug me but otherwise it is fantastic and does pretty much everything I want and needed. Would recommend, for sure.

Haha! I seriously, no joke, get a huge headache when I look at the back of the equipment rack...or consider how I would have to rewire something. It's pretty complex. Unnecessarily so but it's mine and I love it.

And it does sound great.

Thanks guys.

Nobody has. Took the pictures yesterday. Well, most of them.

Woah!!!!

That and the RF preliminary measurements have me:

BRB!

Not sure if tagging works the same here but ...

@Ricci

@electrodynamic

Inevitably the new BHS-24 will get tested. The obvious question will be how different is it from the "regular" 24" driver.

Should the new driver be tested in the same 15cuft enclosure or a smaller one?

It's terrible. I'm sure they spend half their budget getting Cameron to say "nice things" about it.

This makes Salvation seem much better.
