Default Tom Danley on the TAP Horn...

Tom was kind enough to answer questions on the Tap on his forum site. I thought I would post a link to Tom's reply here so those interested could read it. Regards Moray James.

Default it's not just you...

several pages of Tom's site have been down for a few days. So my guess is that the issue is at Danley sound rather than the server as his main page is up. Keep trying as it is an in depth answer. Regards Moray James (checked prior to posting and still down)

Interesting. The only difference I can see is that Tom's does not have the driver co-incident with the port. Is that enough? Unless, of course, there is more going on in Tom's than we guessed!

Oh, and a direct link for those interested.

Highly interesting, can hardly wait until the innards of Tom's creation is revealed.

Default As far as I can tell...

the difference between a Transflex and a TAP is the length fraction of wavelength used for the line and of course the fact that Tom is using a horn flair which will of course be a little longer than a straight parallel sided duct for the same tuning frequency. The horn flair will provide some additional load and perhaps some limited gain. Since the TAP is a 1/4 wave horn ther will not be much if any gain (due to the horn) at resonance but it will controll upper harmonics better than a pipe would. Perhaps GM could comment on the gain aspect. I also assume that the position of the reflex duct is not all that critical but don't quote me on that. Best regards. Moray James.

PS have been keeping a sharp eye on the US Patent Applications and there is no sign yet of Tom's application (re the TAP). I fear that this is one design that Tom may not snag. Bummer when you find out that someone else had your same idea ahead of you and got the pattent. In my searches I have found my own idea patented twice. but wonder seriously if they will ever pay the cost of the application and patent along with maintenence fees.
