This just confused me that little bit more, it seems everyones divided on the tapped horn thing.. from what I can gather, tapped horns sound nice for midbass but their phasing issues and little blips mean they're not as accurate as a flh, even though they sound subjectively nicer to some? Am I gettin the right idea?

Tapped horns frequency and phase response usually extends smoothly enough to cover a bit over two octaves (30-120 Hz, 60-240 Hz etc.) when used with 24 dB per octave crossovers.

A front loaded horn may extend as much as a decade (30-300 Hz, 60-600 Hz with usable smooth response.

Used within their respective limits, either can be quite usable.

Ahhhhh I see now! So is it just a matter of choosing a useful 2octave bandwidth and designing a th around it? I'd be happy with them playing 1 octave to be honest, my mid tops cross at like 125 anyway

Art, can you publish your 210th plan, or can you email it to me? I want to give it a try.
Sergey,

The 1x10" and 2x10" TH really were just done to re-use some existing cabinet shells and speakers that were gathering dust. Not an optimum design in any respect, but they do well in the kick bass range with a healthy bit of EQ.

The Keystone exit smoothed out the response slightly compared to the straight mouth, but you will have to approximate the size from the photograph, as I did not write down the dimensions before selling the cabinets.

If anything, a Paraline is *less* efficient in the upper limits of it's response, compared to a conical horn.

If you look at the frequency response of horns with a very narrow coverage angle, you'll notice a series of peaks and dips. This is due to a combination of factors, including comb filtering and often due to the horn being too small.

A Paraline is *very* narrow, so you see these issues.

That's probably the reason that VTC, Danley and Yorkville only use them as the first stage in a larger horn. It's basically a horn feeding a horn.

I still like 'em though. You can package them in some very unique ways.

Thank s a lot, Art.
It's seems very compact too.
Can't wait the weekend!

Aloha Art.
Tried to build it today... There is something wrong. When I followed those dimensions I ended up with something like that.

Or am I wrong? (black is metric size).

The question mark dimension is 5.25 inches, 25" (interior dimension) -19.75"= 5.25".

Note that you can sometimes get more bandwidth and the same efficiency with a FLH. Whether a FLH or a TH is optimum will really depend on the driver and how much space you have to work with.
