if the sub lacks bass power, then putting it at a corner would increase the 'bass', but if ur sub can pack a punch then corners can distort the bass effect drastically.. if u see HTkaki post of his HT area before, u will realise where he put his sub is a bit weird.. but after i got my svs n did my calibrating n finding the 'sweet spot' i find my sub position oso almost similar to him..

How weird is it ? Any Pic to show ?

My Sub lack bass especially watching astro. No budget for active sub yet, maybe in future. So I think the best way is to put it to the corner. But then, my left corner is about 4 metre from my tv. By placing there, we might just hear boom sound from left which will sound WEIRD overall.

Yah loh! Over here in Sarawak Hi-Fi product so expansive! Really got slaughter buying HT product here!    u really got a very good deal in Satok karrr???

Now that is an excellent way to sum up a good sub!   Problem is finding such a sub is a big problem.   The few sub that I listen to is, the shop set the  LFE level very low, their reason is that surely when u 'slam a door close' for eg  the effect is minimum!    I have a sneaky feeling that they don't want to show how distorted the sub will be when volume is on the high side. I did listen to a velodyne CHT-12R but the volume is just set to less then half, I want it to set to 3/4 volume & LFE set to -7db to try it. But the shop say no can do!   That will be too big!

Anyway I am a bass nut so still looking for a good sub. BTW svs now got PC12-NS @ USD549 don't know if compared to Velodyne CHT-12r or Paradigm DSP3200 better?

Only with a SPL meter could tell whether you have the right setting.

Agreed, they're are not always accurate and there's no way we could tell. The best way is to use Audyssey, and then re-check with an SPL meter and adjusts.

For Audyssey, there's no way to see the EQ set by it from the calibration. I didn't like it, so, I set it manually.

mentioned in post #968 - Velodyne Impact 10 is abt RM1.4K while Impact 12 is abt RM1.7K.
Then, that's your call  . I would opt for a properly calibrated setup

It is always easy to calibrate the system wrongly and extremely difficult to get it right  Then again, one man's meat is another man's poison

Yea, I figured, But my normal watching vol is -10.0.

If you set the LPF to 80 hz on the sub, any frequency above 80 hz will be gone including those from LFE channel. The setting at the back of the sub will not tell the AVR to direct the frequency between 80 - 120 to the front. The lpf filter on the back of the sub will be the last filter that the sound signal will pass thru. So you should set it to the max possible. If you can by pass it, better still. Let your AVR control your frequency setting. Not sure if you get what I meant here. Let me recap : there are 3 setting here. The first 2 settings are in the AVR which is the LPF for the LFE channel and the freq cutoff for the front/center/surround channel. Then there is another manual setting for the LPF on the back of the sub. The correct setting if you want to follow THX recommendation should be :

LPF for LFE Channel : Set to 120 Hz
Freq cutoff for Front/Center/Surround : Set to 80 Hz
LPF setting at the back of the sub : Set to max possible (120 Hz)

If u follow this setting, the full freq range from the LFE channel will be send to the sub together with the signal from F/C/S which is below 80Hz. When this signal reach the sub, it will be able to pass thru all. If u set at the back of the sub to 80 Hz, those signal between 80 -120 Hz from the LFE channel will be filter away. Hope this is clear enough.
