Im relatively a noob to some degree so I need some help.
Will adding an SVS SB3000 subwoofer (front firing sealed sub) be a good idea to complement my SVS PC13 Ultra (downward firing ported sub) given the following:
1) 100% movies
2) Bedroom with 15 sqm space (160 sqft), carpeted.
3) Subwoofer will be placed in front around 4 feet apart. They will not be symmetric.
4) No room treatment and I am not allowed to put any due to WAF
5) No, I cannot get a ported version due to size (height) and limitation of location i can place them. I cannot go over 16" height as it will block the center speaker. In short, max size is 16x16x16 inches.
6) I can only place them in one location and cannot move any of my speakers anymore. Space is very cramped and no other way to change locations. (computer table fixed to wall, etc)
My setup: 5.1.4
TV- Samsung UA78JU7500
AMP - Denon x4500H
Speakers front - Kef Q350
Speakers center - Kef Q650
Speakers Rear surround - Mission
Speakers Top Front Audyssey - Klipsch 5650
Speakers Top Rear Audyssey - Klipsch 2650
Subwoofer - SVS PC13 Ultra
Player - Apple TV 4K (streaming) / Zidoo z9s (4K movies in hard drive)
1) Will adding an SVS SB3000 subwoofer (forward firing sub) be a good idea to complement my SVS PC13 Ultra (downward firing sub)?
2) If not, will selling my SVS PC13 Ultra and getting 2x SVS SB3000 (front firing sub) be a better choice?
3) If I go 2x subs, do i need to buy a mic and some stuff to calibrate the subs manually or will the Denon Audyssey XT32 be enough?
Below is a rough diagram of the room (note: grey boxes are computers/drawers/etc which cannot be moved as they are fixed in the wall. Also TV and center speaker is a bit front and there are drawers below them.
