room acoustics for beginners

[hardcore_gamer99]

So i have just build my 2.1 setup with Denon x4800h DALI opticon 2 mk2 and svs pb 2000 pro. Now this subwoofer is not performing i tried many settings watched many videos and evens subwoofer crawl failed. Now its time to step into the world of room acoustics. I am attaching a video that gives 360 view of my room with instructions of each wall written with my sitting distance possible. So, would like to know the best wall for wall mount where there is minimal need of room acoustics. Like i have written which wall has wooden door to left or right or open window so that acoustics can be treated according to it. As its a bedroom not dedicated ht room i would like minimum required acoustics. The main issue is subwoofer only though speakers sound best. I will be getting rid of pc table and tv unit as well from this room and will wallmount tv. So which will be best wall so that i can put my subwoofer in front only to blend with dali fronts.

Enter your room’s dimensions into REW’s ‘room simulation’ then your listening position and the position of your speakers , you can virtually drag things around and see the FR change.

FR means?

 

[Keith_W]

FR = Frequency Response.

If you have done the subwoofer crawl, does that mean you have measurements? Can you post them?

I did crawl 4 times the issue is that when i put the subwoofer in my chair and do crawl for example i found this very good position when i played spectre movie opening scene where building collapses it was very deep rumble but when i pu the subwoofer there then in chair i was not getting that bass this is the issue how is this possible? but it is there. what should i do next?

This is a tiny room with a big subwoofer, so you are asking for massive room modes up to quite high frequencies. So, first, enter the room's dimensions into the REW simulator, try to find the best location from there, and then use the Denon's dsp room equalization. Expect a more or less flat response in only one listening position.

can you tell how do i do it i know nothing about rew i just unboxed my umik1 mic. 5 minutes ago. also what is denon dsp?

For measuremnt with a UMIK-1:

Your Denon will have some room correction software built in, probably Audyssea. Have a look at your manual.

off topic but can you suggest i want to buy svs ultra center channel but have dali opticon 2 as fronts will i have much issues?

 

[Willem]

Probably not directly in terms of connectivity. Whether it will sound right, who knows? Why not get a Dali centre speaker?

i can go with dali opticon vokal will it sound good as i cant do audition. I liked dali opticon 2 without audition

i hope this will help me umik-1

The Julian Krause video is as good as it gets.

Denon dsp what is this?

DSP is Digital Signal Processing, which is the hardware technology behind modern room correction. The software would be something like Dirac or Audyssey.
