It's either sms-1, anti-mode or as-eq1.
As for audyssey, it's audyssey pro that have proper resolution to get accurate lfe.

bro..is it SPL meter we must(wajib) have to fine tune our sub....

i think i need to know what is "sms-1, anti-mode or as-eq1"...do you have link
*
Google bro.
SPL only measure db at desired freq selected.
SMS-1, anti-mode, as-eq1 calibrate the sub for the inherent sub/ room weakness.

I believe majority are using front firing sub.
Looking at recent trend, new subs are configured in front firing.

Last time I did a mini bulk (zero profit & charity) bulk for svs owners.

You can get it from Center Circle.

boss, I presume you are using PB13 Ultra, right?  And Auralex Gramma can handle that?   hmm.gif  I'm having PB12+ and I can't fit Auralex Gramma under it... thinking of getting the Great Gramma wink.gif

Boss, you didn't let me know you wanna let it go. I just got another piece of gramma 3 weeks back.

No boss lah, small fly only sweat.gif  I'm not sure if I should get another gramma to use it together with the one that I have or get a great gramma instead.  blush.gif  So you are having 2 gramma for 2 sub or 2 gramma for 1 sub?
*
Boss. Now it's one gramma and one great gramma. A great gramma is sufficent for PB13.
Gramma have no problem holding PB12. It's just out the range of the 6 spikes under neath.
No harm if the wooden body of PB is having contact with the gramma.
Yonggoh, Bryan, Htkaki are all using gramma with PB. nod.gif
