Hello Angelo,

Even though it may not be a good idea to use a phase plug in a straight Upper Bass horn, I did find the information educational, and just wanted to thank you for the link. Thanks also to Romy for his comments on the subject.

The design of the Upper Bass horn may incorporate provisions for a removable ring-type spacer allowing instant creation of a front chamber (this simply moves the driver deeper into the horn, requiring that the tail of the horn be longer... It also means I would have to block out the additional length in the rear chamber when not using the spacer). The only reason not to do it is the fact that in my case, when not using the spacer, it would further degrade driver alignment relative to the Bass Horn (45Hz). This is due to the walls I have to work with.

Best of luck with your Orpheans,
