My plans to build Altec 19 inspired speakers are now under way, with the 811b horn I ordered in transit. I have been in touch with Bill @GPA and am working through shipping options to get the drivers to New Zealand. I have also decided upon a plan for the cabinetry - more on that later.

Decision on which XO to use is now the only hurdle. GPA make their replacement XO, which is one option, but the Zilch version would likely cost me less, and I am happy to do the work myself. I do not plan on bi-amping however, wheich I understand is one of the key benefits of the Zilch design. I hear mixed reviews re sound quality.

Just looking for some opinions before I commit.

Thanks
