The thing that is nice about Martin's solution is that you can essientially "dial in" the amount of detail you want. Like you say, I can't get more detail than the Fostex's can provide. You can tone down the detail of the Lowther's (or not) depending on what you want. I think I remember a post where you talked about adding the filter to the Fostex drivers - do you also recommend that, and what does that do to the presentation? Phil.
