Final tuning includes the PEQ in each of the two subwoofer amplifiers. Results? Measures +/-3dB flat. Small unsmoothed dip at 52 Hz. All speakers set to small. All crossovers set to 80Hz
Yesterday's lab: "Pacific Rim."
Ran the MVC at -17.5dBfs
Ran the subwoofer levels +10dB
Ran CC +6dB
Mains and surrounds, +/-0dB
I just came across this thread via the REW one, so apologies for the late arrival. All I wanted to say was that the bit I've bolded above may be worth altering: I know it's a kind of defacto standard to put speakers at 80Hz crossover, but I've found it's well worth trying higher settings, especially at the front. While the sub can start to become more localised, so long as the surrounds remain around 80Hz (assuming they are capable) then the surround effect doesn't 'move' towards the subs.It helps if the sub is at the front of the room as well, though this seems to be a popular arrangement anyway It does require an AVR that allows crossovers to be set individually of course, so if it's a global setting then you're far more restricted.
I've recently set up my new MK Sound MP150 series speakers and a pair of DIY 15" sealed subs. I have an Onkyo 818 AVR with XT 32 and a Beringer sub amp with DSP for additional Pre (and Post) Audyssey tweaking. However what I found with the aid of REW is that the crossover set by my AVR (70Hz for centre and fronts) was simply too low. The REW results confirmed this as a dip especially in the 'bass presence' range around 100Hz making the sound seem 'lightweight', raising them to 80Hz still didn't sound right either.
I ran REW measurements increasing the crossover one step at a time and ended up with it set to 150Hz. This might seem high considering they are £1000 each speakers, but no point being 'macho' about the crossover setting if it doesn't sound right. FWIW I left my surrounds at 80Hz (up from the same 70Hz set by the AVR) so that the surround effect doesn't become shifted to the subs.
Anyway, enough waffle, some REW responses just to show what I measured and perhaps give something for you to try (even without REW I could hear that it sounded better).
