Well, I loved, loved it loved it… but today I decided to experiment with integration the new horn into the system and learned that it would be far much complicated and take more efforts. Below are 3 sweeps form listening position, Firs is the new horn alone with 18.3uF and 3mH coil.  Second is my Macondo alone. The third is Macondo and the new driver work together. 

I have spent an hour (uselessly it takes for me minutes or even seconds) to listening quite completed material and frankly speaking I hate what I heard. I did some adjustments but the pure Macondo allays was more interesting. The new horn added some heaviness in sound.  I was driving the volume of new channels down but even at minus 12dB (!!!) is feel that the new channel brings the elegance and chick if the Macondo upper bass and lower midrange down. Yes, sure the new channel creates a coupe dbs bulge at “heaviness zone”. However if I create the same bulge by my Macondo the upper bass channel than the bulge doe not bother me at all and practically not auditable.

The concussion is that most likely I need to roll off my upper bass sooner and sharper, reducing the penetration of the upper bass channel into the lower midrange channel. Also I have learned that the new channel much be ~ minus 6dB relative to the MF channels as if not then  it does move the image up. I was playing Carlo Maria Giulini magnificent performance of Brahms 4th (nope, not with Chicago but with… Wiener in 1989, good luck to find it!). What could be more strings devastating then the late Brahms? The recording is compressed and quite “flat”. The Macondo with new driver converted it into such a horrendous mess that it would be shame to name. Ironically Macondo without the new channel or … the new channel along played the recording way better. The same is with my beloved Cello and Piano sonata by George Walker – with the new driver it was laughably poor until I was driving the new channel at minus 18dB (!)

What it boils down so far that it would requires much more precision to set the arrangement with new horns to operate properly, however I do not know if I get any benefits then. Defiantly I will continue to play with it and hopefully I will find some kind of wining setting but so far the result is not worthy.
