Re: subwoofer alignment
I Shane,
I would have thought unless you wanted an extreme amount of bass, 6 x KF730 with 4 xSB1000’s would be a good match. I don’t see much point in getting more subs unless you get more 730’s.
Anyway if you need more LF you could run the SB1000’s as a center cluster, possibly in a tight packed endfire arrangement if you need to limit the bass on stage or run 4 a side of SB1000s with a center cluster of the TX9s.The delay to align the center cluster is not critical other than how it affects the pattern of the LF, however the outer subs must be aligned with the 730s.
Gunness focusing the 730s from memory takes about 7.5ms in the UX8800 but only 3.13ms for the subs … so if the SB1000’s are physically aligned with the 730s you will need to add 4ms delay to the SB1000s. Getting that right will make a big difference around the sub crossover frequency (100hz)
730s sound really good but don’t go very loud especially when using the UX8800. One trick you can do is run a low pass filter at about 14 or 15Khz on the mid-highs and they will hang together a little better when you push them.
Here are some plots that may be of interest -
The top pair of plots are for 12 boxes - L C R
So you can see how the delay effects the pattern, the RHS plot has the center 4 boxes delayed 5ms while the LHS has no delay .
The other plots are for 8 boxes (all staked 2 over 2)
