KRK ERGO

Good point about the latency.

I'm not concerned about my present set-up since the ERGO would be between my pre-amp and power amp and my sub connects to the pass-through port of my power amp. But what if I were to ever upgrade my power amp and the new one would not have a pass-through port.

I will ask too and see if we get the same answer.

I was told that there are no issues at all with latency when using ERGO.

Take a look at the JBL MSC1: http://www.jblpro.com/catalog/general/Product.aspx?PId=286&MId=5

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.
