Dunlavy SC-V schematics and repair help?

Tweakers' Asylum

Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ.

Hi, just thought I'd take a shot. Does anyone know where I might find the schematics for the xovers for sc-v's? Also, if there's anyone who has actually worked on these before I would love to ask you a few questions. We're having an issue with the upper range drivers being about 4db out of wack...I'll get into it if anyone actually responds.
I am hoping to have an informative mechanical/technical discussion so please do NOT bother respond if your only comment is something along the lines of: "those speakers suck anyway" "what cable are you using" or "try a different power amp." I don't know of a component (other than an eq) that can adjust for a frequency spike on the order of 4db :)
FYI the signal chain is very good, Bryston power, Benchmark DA, no preamp (using the DA's volume control) no, not the best ever but good enough not to be the issue.
Speaker position has been optimized in a highly acoustically treated room of a recording studio. Other high end speakers in the room have not exhibited this problem in the least.
We have scoped the individual drivers at close range with pink noise and all drivers (of similar sorts) of both speakers exhibit very similar frequency curves and levels. Polarity was checked with the old 9v battery check.
We have found that using a phase linear digital EQ at the output of our Pro Tools digital recording system and attenuating 4.2k by 4db with a fairly narrow Q results in what we consider to be "accurate". As a note, these speakers are used in high end mastering studios without modification so, any opinions aside, we feel there must be some problem to be causing this discrepancy. We even had a pair of Lipinsky speakers in here, a design based around the Dunlavy's, and they did not exhibit this 4k issue.
I appreciate any help, thanks.
