My bedroom is about 1650cu feet. I have some corner bass traps, but it's really not too bad considering I have a queen size 2 later bed in there as well as a couch.
I'm still experimenting, right now I have Dirac for the subs and a manual YPAO after the crossover point (80hz). I may also not use YPAO and the rsc filters too and just opt on measuring with REW and importing the results into YPAO manual.

Will share graphs when I finalize stuff.

For a room that is about 200 sq feet with dual sub is a lot

Nice, look forward to your findings as usual, bet it sounds awesome too.

I'm using DIRAC and tried both custom and default curves for all channels. In the end settled on the default curve for now.

I thought the best matching are ported sub + sealed sub?

No, it's generally best to match the same sub to one another. It's also much easier to EQ and find proper sub locations.

But a ported and sealed sub can be mixed together though extensive know how of room modes work, EQing, as well as time and patience to find the best location for the subs. Get them right and you really will have the best of both worlds.

ic, so you didn't think of best of both worlds?
Btw, saw your room at Actsessory FB

Not enough space for the PB2000 lol, not that I don't want. The only feasible location I can put a PB2000 is under my PC desk, but that place isn't good at all for a sub.

Haha yeah that pic was taken when I just had the Prime Sats as my main system. Small little guys, but definitely gutsy.

Ya the PB2000 damn big and bulky even put in the living Hall and if put in a small room all things shaking including your ceiling
So what was the replacement for your Prime Stats?

Can explain how does the ddrc-24 work in home theater setup ? I am total noob in dsp

You will need DDRC-88A for your case. Not one but two since it is only 8 channels. So, in a 7.1.4, you need 2. It is basically a room correction device but with a more powerful equalisation as well as better flexibility in user setting. Having said that, sampling resolution is capped at 48kHz. Those with huge collection of hi-rez files may be disappointed.

Datasat uses Dirac Live.

Sorry missed your post.
Basically think of it as an external room correction and DSP for your speakers, instead of one being built into a receiver or pre/pro.

It's no secret that DIRAC is a lot more advanced than YPAO or Audyssey (or MCACC). It's just more sophisticated, has a lot more manual control and since minidsp devices are compatible with REW out of the box, it gives pretty much everything you need to correct a room as best as possible (consumer wise).

That said, it's not a plug and play device. DIRAC has a learning curve as does REW (as you already know I'm sure).

I am blur blur here on Dirac. Is the unit attached permanently to the audio system to adjust the equalization curve based on the actual condition of the room acoustics? Does it use USB connection to the computer to make adjustments to the equalization? No microphone required?

Is just another different type of auto correction like YPAO or mcacc

I believe I already know about this as an alternative method of audio calibration. What I am blur is how this works "without a microphone"? Using microphone to a computer with USB connected to the Dirac for calibration? If not require a microphone, how does it "detect" the room acoustics?

If Dirac does use a microphone, where is it attached to and what is the maximum microphone positions that can be used. Both Audyssey and YPAO uses a supplied microphone which is directly connected to the AV amp for detection. OR does the Dirac (connected between to the AV Processor/Pre-Amp and the Power amp) uses the "Audyssey" microphone that is connected to the AV Processor?

its require UMIK-1 mic lol

What about playing blurays which have DTS Master Audio that supports a maximum of 24bit 192KHz. I think even DTSX support up to 24 bit 96 KHz. When you say that people with DSD64 384KHz audio files and 24bit 192KHz FLACs may be disappointed, then people who play blurays will also find the Dirac DDRC-88A not suitable. Have I got anything wrong here? Please correct me if I am wrong.

The Dirac specs page for DDRC-88A mentioned the internal processing and sampling rate at 32bit 48KHz BUT did not say anything about the Audio Input Connectivity, BUT both the nanoAVR HDA and nanoAVR stated the Audio Input Connectivity supported sample rate from 44.1k to 192kHz which is within the bluray audio specs.

Also, what about people who uses XLR connections from Pre-Amp/AV Processor to 7.1 channel Power Amp... so, will Dirac nanoAVR HDA or nanoAVR DL be better for Home Theatre using HDMI connections, without using RCA connections? Dirac nanoAVR HDA and nanoAVR DL have 2 HDMI inputs and 1 output.

Obviously SSJBen is giving the thumbs up  :thumbsup: to his Dirac DDRC-24 for his subs. I think the Dirac DSP products should be better than Audyssey or YPAO so what is the situation for people who wants to use the entire 7.1.2 channels (with Atmos/DTSX) with XLR connections to different power amps. Will nanoAVR HDA or nanoAVR be the one that is suitable in such cases? If it is and if it is better than Audyssey, Room Perfect or YPAO, then Dirac is a viable alternative for better room acoustics solution.

This is unfamiliar territory for me so I hope you or SSJBen will be able to clarify clearer for me.
