Here is my plot on Velo 12Q (AutoEQ done) with SR6003 (Audyssey done).

Using cheapo RS digital SPL with REW program. Level = 75dBC

Anyone know how to fine tune sub using SR6003 (i.e. EQ)?

Attached Image

Any sifu done FR on the main speakers? Too bad my RS SPL not accurate for high freq.

wahlau! svs poision. the tot-kong is different category la. notworthy.gif

me still new in HT. man-man lei, enjoy my investment.

one thing i learnt, better moderate or expensive gears, need to find way to optimize and unleash the full potential before jump into next upgrade. at least for me with hard earned $ biggrin.gif

i believe you are master in REW, me still blur rclxub.gif blur rclxub.gif and may get the master input rclxms.gif

your chart looks quite good, the Auto EQ doing its job well.

my previous velo 10R also had sound levels falling off rapidly around 25-30Hz but the SVS can maintain sound levels well below 20Hz  biggrin.gif

anfieldude, that means we should use the Audyssey sub distance rather than actual distance? for 5.1 level matching using SPL meter, should i use the Audyssey sub distance or actual sub distance from the listening position? still blur blur

anfieldude, thanks for the compliment, paiseh paiseh. still got a lot to learn from all the sifus. compare to those tok kong sub and sub equalizer, just kacang nia.

i believe the room treatment helps a lot.

Actually, maybe gocitygo can post his charts here as well. I have seen his waterfall charts, Audyssey and room treatment, and it is awesome.

bro ycs. no super bass trap la.

got 4 triangle traps at the top tri-corner, 3 rectangle traps at the wall-to-wall corner, 1 rectangle trap at the back listening position and 2 rectangle traps at the side of main front speakers. trap material = 1" thick rockwool (80 kg/m3 density).

plenty of foam traps the wall-to-wall corner. i believe yours no less that me.

next, plan to DIY the diffusor recommended by you smile.gif.
