25Hz Tapped Horn

Recommended Posts

Yea email Erich yesterday the flat pack kits are gone to bad snooze you loose is right.

 

That's too bad.  If you decide to build these, I'd still recommend the Anarchy Exodus woofer, if still available.  It's unlikely Erich will order another production run of flat-packs.

Oh, I am sure it works... and works well.

I still am toying with the idea of some type of tuba... I just can not pull the trigger because there are to many variables that I am not comfortable with yet.

One of which is the myriad of different designs and the effect of those designs on sound.

There are muliple folds, there are long throat designs... who knows what each sounds like.

I'm no expert, but IMO, the fact that the useful range of these tapped horn subs is confined to below 80Hz minimizes the negative impact of the multiple folds in the path. The mid-range comes from the mains, not the subs. When using Pono to play the demonstration tracks (WAV files) from the Danley site, the sound is incredible. While listening to Donny's Harley or the Train Start tracks, the palpable sense of the H-D V-twin or the massive train is startling, but, at no time do you sense the speakers (mains or subs) as the source of the sound. You don't listen to the speakers, you listen to the program.

Compare that to the folded path in any horn that is required to generate output up to a crossover point of ~400 Hz,well into the mid-range territory.

I plan to start a thread to act as a clearing house for recommendations for excellent digital recordings, such as the Danley test tracks. I'm interested in the forum members' favorite high resolution tracks, whether free or commercial. I know of tracks from Linn and others. Perhaps this weekend I can get such a thread started in 2-channel.

They're just like speakers.  You'll never decide what you like by looking at specs or reading reviews.  you need to hear them.  You'll either need to audition a couple close to you or just build a couple and see what style you prefer.

Me too these tapped horns will be my cutting teeth on DIY subs. If I end having the necessary skills to do this I can see me building more LOTS MORE lol.

Mine are now sitting collecting dust now ;-(

Scrappy - Why are they collecting dust, did they not live up to your expectations? To bad your not closer I would take them off your hands and blow the dust of them :)
they no exceeded my expectations very much. However I downsized my living room setup and went with smaller stuff and they stuck out a bit too much in the room in the front for me so I moved it. And the rear one doesn't fit behind my new couch since it reclines so much lower than my old one. So they are both in my storage room right next to he Cornwalls also collecting dust. Makes me sad I just have no where else to use them right now.

Thank you Carl for all the help!!

 

Got the first box done, learned a lot on this build the most important being test fit the darn thing before glueing it. I had glued the internal folds and pressed them overnight. The next morning I started cutting the panels for the second box once I got all the panels cut I went back to the first box. I messed up and glued the internal folds and the outside panels BEFORE test fitting the side. Laid the side on and put my clamps on it to get the beloved seq. out of PL. Well I had a board cut to long on one of the inside panels because I had a good crack all the way down one die I could not get it to close. Carl advised to PL the crap out of it and keep my fingers crossed...I did and it worked. This lil sucker sounds so clean and compliments my H2's perfectly. Going to start glueing the second one today and yes I will test fit the last side before putting it on!!!!!! Hope the link works.

This is a very fun build and is a great introduction to DIY audio. I'm no woodworker as you can see but it was a blast and it sounds fantastic. Thanks again Carl for all the help.

Got the second box done. I could not wait to fire it up got it all wired in and NOTHING! Called Carl and we went through a few things to tbshoot, finally found the problem. I had wired the binding post to driver wrong. In my defense I did use a different style binding post than the first box but really that no excuse I should have tested it. Anyway on the first box I had the driver terminals points up and the binding post just a bit higher than the driver. I didn't like the way the wires laid on the board when I test fitted it. So on this box I rotated the driver so the terminals on the driver were pointed down and mounted the binding post below them. THANK GOD I did this as I was able to reach through the mouth opening and unscrew the binding post and rewire them correctly. This build would have been a lot easier if I would have gotten a flat pack but I don't think I would have learned as much and I'm pretty proud of the fact that I did all this with no experience just a skiilsaw and a straight edge. I still need to sand them down and duratex them but for now I'm going to grab a cold beverage and enjoy them.

 

All is well in my listening room and I got to say I'm very impressed with how these things perform. If you have a small listening room and want to add more bass with a minimal foot print these are an excellent choice. I will never buy a commercial sub again not to say they are not worth it but I had a blast building these.

 

Thanks again to Carl for all the help you are the man.
