I'm planning a room change and it seems that multiple smaller subs might help to supplement an existing pair of sealed 15" subs I have already built in particular to help with 60Hz and 90Hz nulls. This is based on room measurements and comparing with the REW room sim, which is pretty accurate in my room. It seems the ideal locations for the rear subs is high up the rear wall, so I'm limited by size of the cabinet.
I'm thinking of multiple subs using the Peerless XLS10 driver in a 22 litre cabinet, possibly using some commercially available 'in wall' versions for two positions that are more visible (since they come with neat grilles which saves me making them).
Most of the talk on here seems to be using larger drivers, but I don't have the space where they need to be placed for larger subs. Since it's more 'mid bass' that is the issue then I'm hoping that 8 of these drivers spread around the room will give plenty of headroom and the 'ULF' will be covered by the two 15" placed together at the mid front wall position. The 15" pair already give me enough SPL down to 10Hz for my requirements (113dB at the MLP, and I tend to listen about 10dB down from reference), unfortunately they suffer the 60Hz null in the front mid wall position, but are fine below that (with eq to pull down the two main peaks at around 53Hz and 27Hz).
What issues am I up against using a mix of larger and smaller subs? I already use an iNuke 6000DSP for the 15 pair and 8 of the XLS10 could be powered from another 6000DSP (two channels of 4ohms), so will have good control over delays and parametric eq/crossover control between the ULF and 'mid bass'. I'm thinking to roll the 15s off at 40Hz, so the XLS10s will take over from 40Hz to 90Hz (I'm using on wall MK Sound MP150 LCR and matching S150T surrounds). The overall eq will be done by Dirac, but experience so far has been to optimise the subs manually first and use the DSP to pull down the big peaks individually on each sub.
Does anyone have any experience of this driver (even if used as part of a main loudspeaker)? I can get them for £90 each so not a King's ransom to build a pair to try out and use my existing iNuke to power them for testing, but any advice would be useful.
