Instead of building a system capable of overkill and hearing damaging output, the low noise floor would mean everything would play reference levels at substantially less
I asked about location because of various construction methods, and maybe even product availability. I asked about seating needs because maybe you don't need quite so
big a room, and with a small seating count, there are ways to use some of that space in other ways. A big advantage you have, is how far all the seating is, from boundaries.
But I can see ways to shift budget, time and energy around, (and even space) to maybe come out cheaper with even better overall performance.
The rear subs are maybe a gimmicky choice for me, If they start to blow air into the seating, that's a big distraction. I also really wonder if you actually need them? (I could easily
drop my dual ServoDrive Contrabass subs (2x15" drivers with dual 18" passive radiators) and front three JTR T8s into that space and know I could hit reference levels with ease, so I get
what you are aiming for, and should aim for.)
I would not plant two big subs that could inflate chairs, right on top of seating. I've caught that effect before, and it is a real distraction. Tactile-ness not with standing, but there are better
ways to achieve that.
Why all the MDF at all? Is drywall a common enough product where you are?
The ceiling only looks low, because of the big beams, and the large square footage. My calculations are a 9.4' ceiling height and I expect a pair of beams drop the height to 9'. Do I have that correct?
The Ceiling height is correct, yes. I was thinking MDF just because of the density compared to Dry wall, I will defiantly now be taking your advice and will have be making both a inner insulating
layer and making all outer surfaces "soft" I guess you would call it? So re-insulating the inner walls and no MDF or Dry wall but Cloth of some nice looking sort, to counteract any reflections..
I've only put two dual subwoofers behind the seating because I already own the driver, but It's looking to be a bad idea if it's going to be a distraction. Would love to hear your recommendations on ow to fill a room and entirely as possible with bass, have no flat or dead spots...
The Location Is Australia, South Australia, Adelaide...Yes we defiantly have dry wall, it's called Giprock here, it's just dry wall, there ae plenty of types of drywall including the theatre Sound dampening dry wall, but man it's big $$$, same goes for the Theatre versions of Insulation. As all inner surfaced will be soft (fabric) with Insulation (sound deadening) directly behind it, I thought I would go with the dense MDF as a extra noise lever reducer, at minimal risk to reflecting sound waves.
I gotta say I'm learning so much on this forum, can't believe It took me so long to join. The room is already on my property, It's was a fully in-closed garage, (2 car) It already has power 2x (240v 10amp) breakers, which will do plenty for any lighting or small/non heavy power drawing appliances. I will be fully enclosing the server rack and the fridge inside a closet of some sort that will flush the whole rear wall, I will also move the doors to the (Left) if you're looking in or (right) if you're looking out of the room.
Things her in AUS are 3-4 time more expensive than in the States, as not only currency exchange but businesses here "up-mark" the living Hell out of stuff. (E.g) The receiver i purchase would have cost me $6000 AUD with 10% GST so $6600 I managed to get a 240v one from the US 3299 USD on special after some intense hunting around, even at flat exchange it should only cost $5600 AUD...It's a huge cost for a single piece of equipment. In the end it ended up costing 4650 AUD which is a massive $1950 saving, Everything is like that unfortunately.. Sorry for the rant.
Thank you for these extremely valuable tip and advice.
