In my case, it has nothing to do with convenience, and believe it or not, everything to do with quality.Shrink-to-fit, badly-mastered recordings... These are the cards we've been dealt. Ripping CDs is the sort of ritual I hate. I nevertheless spend c...

Oops,
I'll send the images again once back at work on Monday.
The thraot size will be 7 inches.
Yes I have thought about paying someone else to do the work, but that sort of skilled labor is super expensive around here.
And... Yesterday ...

Here are a couple of shots of how the inner surface of the new rectangular mid-bass horn will look (shown with driver; an AK151). This model is based on a calculation for an exponential horn.These images do not show wall...

Klaus,I should start by saying that I'm not a scientist and not an engineer. I arrived at the following conclusions as a result of a little research and some thinking about the problem. It is possible that I am incorrect.I don't know how yo...

Klaus,
Thanks very much for the offer to help.
I have a copy of the latest version of HornResp (and also of WinISP Normal and Pro versions).
To be honest, I haven't yet tried either... Been using my "cousins's" (Jean-Michel Le Cléac'h) Exc...

Paul,
Thanks for the comments.
I may have come up with a way of making the BIG horns fairly painlessly.
I found a place that sells large sheets of urethane foam in several thicknesses and several densities.And, Its no big deal to find a place that...
