In this blog there is information and links about the Danley’s new TH-SPUD tapped horn. http://hornloudspeakermagazine.blogspot.com/2009/08/tapped-lab-or-something-like-that.htmlIt is so “tapped” that it is painful to looks at it but they guys cl...

Hello Romy,The tapped horns were easy to construct so I made them while I was working on the midbass channel. I can't really comment on how good tapped horns are because I have never heard other 20-35hz capable systems... it does provide amazing SPL'...

I am actually doing the bass and ULF with different modules and amps. My bass modules are the dual tad boxes driven with their dedicated monoblock solid state amplification. The tapped horn is working for ULF only as it is crossed at 30hz with 18db. ...

As the builder behind these horns, I can answer some of your questions. It's true, I was primarily focused on the woodworking/building side, and now I'm experimenting with amplification and crossovers. I can't speak authoritatively on those subjects...

Above I was discussing the new integration process I used to mate the tapped horns with the rest of the system. Below is a graphic to help explain the listening arc. I just moved the tapped horns along an equal-distant arc until the phasing of th...

I think it might be very interesting to introduce the high-pass filtration for tapped horn and to see how it behaves. It is not only about thermal overload and restriction of excursion. The unloading of none-used bass generally clean-up the transpare...

[quote user="Rewind"]Macman: Maybe your tapped horns were too small. Speedysteve is absolutely in love with his, and you and him have a very similar setup with your 15" upper midbass horn and all.[/quote]Yes, Im sure you could make them better. I bel...

I have 2nd order crossover both on the upper knee of the ob bass section and on the lower knee of the midbass section. My measurements show phase response and the summed spl is as good as it can get. Have you tried the direct servo technology or do y...

I am using sealed bass arrays of 3 per side. I have six 10" scanspeak woofers in total. I aim to operate them from 38hz to 160hz with qtc 0.707I also have a tapped horn that I am using with my current horn system. It is 244cm's high and 125kg's compl...

Would not a 9ft-11ft long bass horn path (tapped horn or any horns) cause a sonic problem if not physically time aligned with the upper bass or mid bass channel? The only way to fix that would be to place the bass horn 9-11ft closer TO YOU than other...

Looking at that diagram, it seems as though Romy has made an artificial centre tap for a conventional filament transformer. You can either get a centre tapped transformer, make an artificial centre tap as shown or not bother with a centre tap at all...

Paul, I am no expert on tapped horns but I think the main (40 year old) principle is that you join the back wave of the driver with the front wave, now in order to have the 2 wave fronts meet, the back wave should travel a certain distance depending ...

Romy,
I like your idea. However, I would caution you on having the outlet of the one side firing backwards. One of the things that is not talked about with tapped horns is they are more directional than a normal subwoofer....
|

I was hoping it was something to do with building Tapped Horns for the low bass. Maybe because I thought Romy wrote somewhere (can't find it) that the line-array bass units were the "weakest" part of the speaker system. I keep thinkin...

Skushino, I found the same thing, TH can only go so high before they start sounding :funny, of course due to the principle involved, if you want to raise the response further from the design the same Tapped Horn begins to work against itself. So one...

It goes quite flat to 20hz with the tapped horn. 20hz to 60hz with the tapped. It has 18db/octave Linkwitz-Riley, and then to dual Tad1601b, where you see the rising of the response around 74hz. I have tamed these bump some, but it needs a little mor...

No, the drivers are the same brand but a different model than yours. They are not 10" but 12", it was a typo I made.They are 30w/4558T00. I guess they have lower fs (17hz) then your drivers. 3 of them in serial makes them 8ohms. I am in the lookout f...

I come up with the idea to introduce 6th channel and add bass array in between tapped horn and upperbass horn. Benefits:1. I can use 1st order lowpass for Tapped Horn at 15-20Hz2. 30Hz+ range become time-aligned3. I don't need to go very low with upp...
