Reed Exodus Anarchy 25hz Tapped Horn - Page 24

I called the CNC company and asked for 50 more to be cut. They might be here in about a week. I need to order shipping boxes though.

Have you had anybody put these in a truck? I have a friend of mine with an S10, and he wants me to build him a couple subs. These might be awesome

The original pictures from the 1st post aren't showing up for me anymore. Any chance you'd mind rehosting those?

Until radman12 gets his server issues sorted, there is documentation over at AudioKarma too.

Has anyone compared a pair of these tapped horns co-located to any commerical offerings? Like SVS PB12 NSD or HSU VTF models?

Question horn guru's...

I know nothing about horns, nothing.

Here's my situation...
My living layout is like a small studio apartment. I don't have room for a sub, except for under my bed. I have 8 inches of height to work with. I'm looking at this as one option. But I told the GF I could do this for about $120, give or take $20. (yeah, good luck huh?).

I already have a 2 channel integrated amp collecting dust rated at 100w p/channel. I need to find a 6.5" DVC that can handle 100 per coil if I'm gonna use this horn design. What specs are most important to making sure another driver will work in this while maintaining the same type of frequency response. Preferably down to 20Hz even, since my Infinity towers put out abundant clean bass down to 35Hz already. So I'm after a magical range of 20-35Hz.
Also, out of curiosity, when adding another horn, does the old "add another 3db for having a second driver" count? Or is it more due to the output of a horn?

My only other option at this point is two Infinity Reference 1062W 10 inchers, which I can fit under the bed. I can get 100db at 20Hz with 100w input and xmax doesn't peak until 16Hz.. I've looked over a TON of drivers and spent countless hours modeling in Bass Box Pro the past few days to find a good driver that can put out this range, handle the power, low vent velocities, and not exceed xmax. But this horn looks interesting and I'd like to build one since I never have. I just need to find a more budget friendly driver, which has already proven to be very hard.

You cannot substitute another 6.5" driver in this horn. This horn is design specifically for the Anarchy driver, if you want to use a different driver you would need to redesign the horn from scratch.

It may not be optimized, but with a MiniDSP, and crossed over below 80hz, the Tangband neo 6.5" W6-1139SI sounds great.
Muchos Gracias to Lilmike and others for the helps!

Just something for those of you that never actually listened to a music being reproduced from tapped horn designs...
IMHO, Tapped horns have two major advantages over any other low frequency speaker enclosure. those would be:

1.) the ability to reproduce music accurately even at extremely low volumes. - vast majority of other subs are unable to do this.
2.) the overwhelmingly precise, warm and rich tone color. - they don't sound like "fast" subs. IMHO, they sound tons better! There is no aggressive characteristic to those enclosures.

my friends and i have built quite a few designs available all over the web, up to 8x15" ones we use in PA system. all those designs do fantastic job of sounding just like a tapped horn should sound.
i'm gonna build a pair of enclosures this thread describes - for my room, to cover 25-80Hz for me

Don't forget that they do it all with little power too!

Anybody in Vegas built one of these that can demo for me?

I know this was quite a while ago but i was wondering if you were getting anymore in? I bought and built 2 a while back with a bash 300 and they really hit hard and sound great. I just recently moved them into my garage/workout room and everyone is amazed when i tell them the size of the speakers inside. I definitely want 2 more since the amp is overpowered for 2 i really have to watch the volume. Still really need to get my amp modded or buy something to put a high pass in. I'm really careful with them but i dont want to blow these bad boys.

Sorry, I disagree.

Horns are resonant devices - so the 'sound' of the horn tends to swamp the sound of the driver itself, particularly as the horn gets larger. Due to this, you can frequently swap one driver for another. For some anecdotal evidence of this, note that Bill Fitzmaurice has horn designs which work with half a dozen drivers, as does Art Welter. Tom Danley uses basically the same folding scheme for three different subs, and just varies the driver and the volume. (IE pathlength is virtually identical, and so is expansion rate.)

The big 'key' to getting one horn to work with multiple drivers is to vary the volume of the horn. For instance, if you have two drivers with similar fs and qts, but one has a larger SD, you're going to need larger horn volume for the one with larger SD.

But there's an incredibly easy way to increase the volume - just increase the depth.

That's exactly what I did to get the Insubnia to work with the Alpine SWR-824D. The Alpine has higher SD than the Anarchy, but it works well in the Insubnia as long as you increase the depth.

If your amp doesn't have a highpass, instead of modifying the amplifier, why not add a passive highpass xover? I believe Parts Express still sells these, they're something like five bucks. It basically high passes the signal *before* the amplifier.

Here's the highpass xover that I referenced : http://www.parts-express.com/pe/showdetl.cfm?partnumber=266-246

Guess they're not five bucks anymore

I seriously spent almost five years trying to figure out why tapped horns sound so good.
Theoretically, sealed boxes should sound better than tapped horns, but I prefer the latter.

That really vexed me, as sealed boxes have superior frequency response and group delay. And if it was simply the high efficiency, than one would expect a big efficient sealed box to sound superior to a TH.

But I think the 'key' to the natural pitch and definition of tapped horns is the in-room impulse response. A tapped horn is a dipole, and John Kreskovsky has an excellent paper exploring the behavior of dipole subs here: http://www.musicanddesign.com/Dipole_modesA.html

And I explore the subject here: http://www.diymobileaudio.com/forum/technical-advanced-car-audio-discussion/144111-up-front-bass-new-way-new-post.html

I have an extra pair of Anarchy woofers, these would probably make a nice addition to my PC setup.

I looked at those before but i was under the impression you would want a steeper crossover slope? Could i just use both inline and would the -12db double? i was looking at the 30hz one. Just want to protect the speakers i dont want them accidently damaged by someone blasting the music. Thanks

I would also like to know if using two of the fmods will double the -12db slope.

If I recall, there is a formula somewhere on their website that explains how to stack the Fmods. I have no recent experience with them, I used them many years ago in a car-audio install with limited success.
I can't just blame that product though - I made plenty of other mistakes.

Are the kits still available?

What is the recommended frequency range for this horn?

If you mean the Tapped Horn flat packs from DIY Sound Group, I don't think he has any in stock. If I remember correctly, he waits until there is enough interest and then buys a bunch at once. But since the drive is no longer available I don't know if there will be enough demand to warrant another purchase.

You would need to high pass this tapped horn no lower than 25Hz, and based on the frequency chart posted on page one you would want a low pass between 80Hz and 100Hz.

Don't Yung plate amps have a HP @ 25hz? One of their lower power plate amps would be a perfect match for a pair.
