KRK ERGO


Has anyone tried the ERGO (Enhanced Room Geometry Optimization) from KRK Systems?

Some dealers are suggesting using this unit in their listening rooms to correct room issues in order to get better sound. Originally created for recording studios but apparently people have been having great results in their listening rooms with this unit.

It retails for about $500US.

Been looking into it, but concerned about possible latency issues. (time it takes signal to go thru unit) Not an issue if using unit full range, but problematic if using just for subwoofers (not intended use)List is around $799 & uses licensed lyngdorf technology. I'm using velodyne sms-1 sub-eq's now (3), but doesn't correct for time, just freq. aberations. Reluctant to run SOTA tube components thru a $500 processor box(Full range). SVS/Audyssey has competing product, but you have to use a AV pre with digital delays (or outboard digital delay) to sync up with main speakers due to 7.5 ms latency of processor. Ergo operates up to 500hz., not sure about adyssey. Have e-mail in to tech support at KRK about latency of ergo using analog ins & outs, but haven't recieved a reply yet.
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.
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.
