Hey all, a few questions around building your cinema room from scratch (new house, currently architecting). I still have flexibility in dimensions, sub layout, and might have to make some choices before the room exists in reality.
1/ I have a SVS SB13Ultra - 13.5", 1000W powered sub. How do I calculate the SPL at sitting location? The - specs page
- is uninfornative (doesn't mention sensitivity for example)
2/ I'm thinking of adding 2 subs to 'cover' the 10x6m-ish room well and have an entry into multi-subbing. Roughly, what would be sufficient for the 115dB SPL at listening? Handwavingly, would 1x13.5 and 2x 12" suffice? (e.g. Dual SB2000
- of course I realise this depends on the above #1
3/ My amp (Marantz 7010) has 2 subwoofer outs. How would one wire this up? Should put my 13" on one, and 12"ers on the other channel (I think they have a 'through', line-out?), or split one of the sub-outs into two signal cables?
4/ I know positioning the subs is a massive topic, but happy to hear any 'first attempt' setup suggestions. Reason I ask: I'm tempted to put the signal cables to the subs into the walls, but that'd mean I have to predict where the subs will be! I'd even be happy to create a few more cable spots just to cover a few likely options. What's a good 'common layout'? I'm thinking 13.5 slightly off-center under the screen, one 12 on left wall, one 12 on right wall (but different spot, not same distance from screen)..
Looking forward to any thoughts on the subject, incl anything I missed or should consider... Am I thinking in the right direction?
