In audio terms, one foot = 1 ms delay. So I added 12 feet to my subwoofer distance in the CBIV menu. Barry explained that this really dials in the subwoofer. Now the group delay for other makes and models of subwoofer may vary some.
You can use REW to more accurately dial in delay and phase to align (a) multiple subs and (b) the subs to your mains

Demand greater honesty and transparency in high-end audio

With Theta, Egglestonworks and Krell since 1998!

Steve and other CB Dirac users;
I don't post here too often but felt compelled to on this topic.
I wanted to add my voice to the others who have been amazed by the improvements brought to their systems by adding Dirac. It's worthy of a "wow!"
I have acoustic treatments which helped quite a bit. I knew there was room for improvement but I still enjoyed my system.
Then I demoed the KEF Blade Two speakers with Craig and George. While I still need another demo to cement my feelings about them, the demo of the Blades and several other similarly priced speakers made the shortcomings of my Aerial/JL 212's combo all too apparent.
So did a small new office system (Devialet and KEF LS50's), believe it or not!
John B @ Theta has always been a wonderful resource. He provided me with screen shots and some other documentation so I would be comfortable running Dirac.
Bottom line: it's like I have a new system!!!
The changes are so profound that I couldn't believe the sound I was hearing was from the same equipment. It has given my system a new lease on life!!! I just can't stop listening to it while my hands, feet and head are moving with the music. I am so engrossed now that I want to hear each cut through to the end to listen to what the engineer wanted me to hear.
The acid test was my wife! She has patiently sat and listened to changes I've made to the system through the years and always said "it sounded good before and sounds good now." This time she sat down, listened to a cut she knew and said "it's much clearer now!" 1st time in years she had been able to discern the difference. And that difference is audible from top to bottom!! Simply awesome!!
Now I am wondering what magic Dirac will bring to the KEF Blade Two.
When I return to my NY system in a few days the 1st change I will make will be to add some distance to the sub settings to accommodate their inherent delay.
There are times I love this hobby; this is one of them!:smiley:

Sonic improvements sometimes sort of lift a veil to some extent. ANd I have a great room with excellent Michael Greene PZC acoustic treatment. Yet Dirac has not lifted a small veil, but a BIG VEIL!

You mean you don't remember me? Back 1999 - 2003, I started and moderated the AVS Tweaks forum and also the AVS Special Guests forum.

I've been playing the game a few years now and understand. I've made changes that have lifted a veil. Some more than others. This is more like raising a curtain. A veil isn't near heavy enough.

Good one. And correct! I'll take you one further. Dirac Live is raising the curtain. And it raises the bar. One of these days Dirac Unison will raise the Titanic!

I know Theta at a recent show in Newport had the new D3 DAC installed into the new CBIVa along with the new 8x2 HDMI 2.0, HDCP 2.2 card. Was there ever a shot of the rear of that unit? Also I'm curious if there has been any pictures of the CBV and the external 12 channel DAC that was announced at the same time as the CBV to partner with the unit to get it beyond the 12 channel internal limitation?

Rod, I don't recall seeing any of that but maybe Craig or Jeff will share.

Steve, we could go down the whole thesaurus for superlatives but I think we all agree that Dirac is a game changer. That there's better coming is just icing the cake.
