The MiniDsp really looks best for my system from what I've read over the last several days. Sure would rather have a rebuilt vintage active crossover though. Going to continue to research this and learn. Thanks.
Hey George, this is worth thinking about.
Crown VFX2. [2nd time re-listed so bound to go soon.] It's a good price.
These things can be a bit 'iffy' regarding their pots. Most times they can be cleaned with DeOxit [or similar].
Sometimes you just have to replace the pots [double ganged].
I'm sure this one pro'ly has problems, but well worth fixing as a project. Ask him. See what he says.
I have two. Had 'em for years and give them a squirt every now n' then, but love their simplicity and versatility.
Other George....
