KRK ERGO

Used as intended the Ergo shouldn't have latency issues,but used as an improvised subwoofer room correction device & not in the signal path of the main speakers, I would assume the 1024 tap FIR filter takes some time processing the signal & a few ms of time delay of the sub vs mains. The JBL looks interesting (& even cheaper). The manual isn't clear about the details of the RMC correction technology (how many filters etc), but looks more suited to use as a subwoofer "controller/EQ". Room treatment is probably best starting point. I've been experimenting with 8 12" subs (infinity prelude mts)divided between 2 channels at various positions & heights in the room (16x21x8'tall)in 3 zones controlled by 3 velodyne sms-1 controller/EQ's attempting to overwhelm modes (confuse them at least)& smooth overall response. None of the subs are "working" very hard with this configuration & more subs seems to smooth out room response.

Hhiggins: With that many subs, you might benefit from another JBL device: http://www.jblsynthesis.com/products/product_detail.aspx?prod=BASSQ&Language=ENG&Country=US&Region=USA or a few of them.

Harman has the BASSQ on their synthesis/performance web page, but customer support says it never came to market. Manual is on line & some AVS members claim to have one. Manual isn't at all clear as to what type of "processing/EQ" it's up to. Sean Olive's research indicates the "listening panel" doesn't "prefer" flat "in-room" response anyway, so working my way thru Floyd Toole's book to gain more insight

KRK has not responded to my several requests.
