The 17.5K is the designed to number. I put it there because the RTA is saying that the main ribbon drops off like the barrier reef at that point. My 52 year old ears here them though. I think I need to double check the
tested value of the caps to ascertain the actual x-over point (but the taper is slow with just one cap, so I am probably getting output from below 17.5). In fact, I will just order decent caps and take it 2nd order.
Come spring I will either:
- Strip the existing baffle and repaint it piano black with several coats of clear (it is scratched up), add the dome super tweeters (or a Dayton ribbon, under evaluation) in a more elegant fashion (tough to do because I like the idea of just continuing the line source, keeps imaging tight, so may just repeat what I have in a nicer finish) or
- Create a new design with an out board bass unit using hivi or JL drivers, and build a rib tower baffle separately that incorporates the domes (or the Dayton ribbon, or a pair on Infinity EMITs modified to have rear output - just use the front frame of a pair of non-working EMITs on the back)
Will see what I decide, but at any rate thoughtI would post my mad tweaks here to stir up activity in the forum.
