Title: I am building the Corner horns! Post by Alex from Oz on 10/31/07 at 09:27:49 G'day All, I’ve ordered the Decware corner horn plans. Should be here very soon - Yipee! :) I’m currently breaking in a pair of Fostex FE167E drivers– about 240 hours so far. This will be my second DIY speaker build and my first horn (well, second if you count a 'cardboard' Buschorn MkII I built for my son ;D). I would love to hear from anyone with some useful hints and tips for the build. Regards, Alex from Oz |
Title: Re: I building the Corner horns! Post by musgofasa on 10/31/07 at 12:43:12 Awesome!!!!!!!!! Keep us posted and put up pics often! About three posts down there is a thread by Wild69 (?) That says Corner Horns X4 or something like that. To date, I believe it is the only comprehensive thread on them. I know that if you have very specific questions, he or Steve are the most experienced. I believe I saw a post from someone else stating that they had a pair, but I can't remember who it was. Can't wait to hear your review! I want a pair of these so bad I can taste it! Take care, Robert |
Title: Re: I building the Corner horns! Post by DaveCan on 10/31/07 at 22:01:59 Great to hear someone is going to take these on 8-)... You may want to get the Decware modded drivers for these along with the plans you have as Steve really recommends them for the Corner Horns. Dave :) |
Title: Re: I building the Corner horns! Post by serenechaos on 11/01/07 at 01:19:20 Cool; have fun! They take a while, keep at it... :) I didn't get the Decware modded drivers, just used the vacuum tube phase plug, then tried a FE166ES-R. A few of the dimensions aren't exact, the drawing is more of a guide than an exact blueprint--If you try to measure it from side to side, top & bottom, the measurements won't always jive, but use common sense, and it really isn't that difficult a build. It just takes time. I'll try to keep an eye onthis thread & relate experiences. Robert :) |

Title: Re: I am building the Corner horns! Post by Alex from Oz on 11/07/07 at 09:02:53 Hi Guys,
Sorry for not replying sooner. I am new to being a contributor to on-line forums. So I'm not in the habbit of checking regularly. Usually, any spare time I have I spend listening to music ! :) :) Plans have not arrived yet. I will post lots of pics as soon as I get underway. musgofasa - I have read the Corner Horns x 4 thread - awesome pics. A little intimidating given the number of hours he spent building these. I don't have a table saw, air finish nailer, belt sander or a band saw. I'm going to see if a bloke like me with 'average' woodworking skills and tools can build these. I only have these basic power tools - circular saw (buying one soon), router, drill and 1/4 sheet sander. serenechaos wrote on 11/01/07 at 01:19:20:
Also, have you sorted the room problems you were having? If so, what treatment did you use? Cheers, Alex |
Title: Re: I am building the Corner horns! Post by DaveCan on 11/07/07 at 17:39:31 Hi Alex, You should talk to or e-mail Steve to see if the 167 is even worth trying in the C-Horns. It's a totally different animal than the 166, here's a few specs; fe167 fe166 Qms 4.63 Qms 3.89 Qes 0.33 Qes 0.22 Qts 0.31 Qts 0.21 Vas 35.94L Vas 45.11L It would seem a shame to take on the complexity of the C-Horns and not use the driver that is recommended for them. In any case check with the man that designed them to see if your ok with the 167 etc... Looking forward to the progress of your build....... Dave :) |
Title: Re: I am building the Corner horns! Post by Alex from Oz on 11/07/07 at 21:03:57 G'day Dave, I bought a pair of FE167E before the new DFR65 was available. I was also considering some other designs which used the FE167E that were much easier to build. This gave me a 'plan B' in case I decided to wimp out of building the corner horns ;D I also read Steve's "Corner Horn Drivers" post on this forum: Steve Deckert wrote on 09/17/05 at 00:57:43:
And this one from the Speaker Builder forum "NEW DECWARE FULL RANGE DRIVER" post: Chris K wrote on 06/30/07 at 20:02:40:

So I can still get the drivers I have modded at some stage. Having said all of that, if I had a time machine, I'd go back and get DFR65's instead! ;D ;D ;D Cheers, Alex |
Title: Re: I am building the Corner horns! Post by DaveCan on 11/07/07 at 22:02:41 Thanks for the education, I should have re-read some stuff :-[. I thought for sure it was the 166 as it's mostly recommended for horn type enclosures and the 167 is used by many in ported type enclosures etc... Funny on the page for the DFR65 the specs are the same as the fe166... In any event it will be cool to follow your build 8-) Dave :) |

Something about the size of a 6DJ8; so the front of the tube is about flush with the front of the driver worked for me. An x-acto knife or scaple works well, just go slow. The tube pins stick to the magnet. I built a clone of Steve's old listening room https://www.decware.com/myroom/myroom.htm in height, width, depth and the alcove. the walls around the corner horns are sand filled. I tore the carpet out and put in a tile floor, and a suspended 8" thick fiberglass "cloud" hanging from the ceiling. (Much better). I built Quadratic Residue Diffusor Panels on stands so I could try them in different locations. I got 2' x 4' x 4" & 8" mineral wool "pads" and made absorbers for the side and back walls, which again I could move around to find the best locations. I built huge bass traps in the rear corners. This site & their forum helped a lot: http://ethanwiner.com/acoustics.html Lotta work, took a lotta time, lost interest, didn't post much for a while. Robert :) |

G'day Dave, You are right - the DFR65 is a modded FE166. I was answering the question about whether the FE167E would be suitable in the corner horns. The main difference is that the FE167E is sheilded and the FE166 is non-sheilded. The DFR8 is based on a non-sheilded driver, so for consistency Steve opted for the FE166 for the DFR65. G'day Robert, Good stuff - thankyou. I'll see how the horns sound in my room when I've built them, then the fun will begin dealing with room accoustics! :) So, now you've done your room, how do the corner horns sound? Cheers, Alex |
Title: Re: I am building the Corner horns! Post by serenechaos on 11/09/07 at 00:01:39 well... Actually I'm using different corner horns in that room now. http://www.frugal-horn.com/ronhorns.html http://homepage.mac.com/tlinespeakers/FH/download/Austin-A166Mk2-plans.pdf I like these even better, but it's probably best not to talk about them here, in a manufacture's forum. It seems to make entire threads dissapear. Robert :) |
Title: Re: I am building the Corner horns! Post by Alex from Oz on 11/19/07 at 11:41:51 G'day wild_6_99, Great to have you on this forum again. Thankyou for the posts and pics of your build - really gave me some idea as to the challenge :-/ Still waiting for my plans to come :( My room has two alcoves as well - I'll post pics and dimensions soon. I have some ideas about how to cut the difficult angles without a table saw. I'll explore these further when the plans arrive. I plan to paint the horns - the sails will be the same as the walls. Oh yeah, I will steer clear of water based paints ;D Look forward to getting some advice from you as i go along!! Cheers, Alex from Oz |
Title: Re: I am building the Corner horns! Post by Young_SC on 10/28/08 at 08:32:05 Hi Alex, Did these ever get off the ground? |
Title: Re: I am building the Corner horns! Post by Alex from Oz on 11/10/08 at 11:02:26 G'day Young_SC, Well...not yet. About every month or two I pull out the plans and get excited, but then get intimidated by the woodwork and shelve them again. Life has thrown a few curve balls which keeps this project on the back-burner. I still plan to build these because my lounge room has alcoves at both ends. Just bought a Decware preamp kit (first tube gear for me!), so this will take my focus for now. Cheers, Alex |
