Last time we wrote you thought I should focus less on tweeters and more on midbass.I am not done yet, but I have found a very nice midbass solution. Somewhat unorthodox, maybe.I have come to love police sirens! Without having A/B compared it to a pai...

Hi Romy, I ended up using a TAD 1101h 11 inch driver, 97db, 38fs, and is what I believe a stronger cone than the Goto 8 inch. The DIY mid bass horn is a 1/2 space 53hz hyperbolic horn with 5in x 5in square throat. Length is about 8'6", height of mout...

There was some kind of hi-fi show in Gernany and it looks like Cessaro showed off a new version of Gamma. They look like change the frame. I really do not like what they look now. They look heavier with new frame and much less elegant. They looks lik...

The best hi-fi LF I have heard came from modified "pro" units (multi-15s) that had a LOT of power thrown at them; and furthermore, the system was "managed" by an... equalizer (albeit, done in real time...). This is not to speak of its FR performance...

[quote user="Romy the Cat"]Twogoodears, What you are experimentation now has yet nothing to do with DPoLS. You deal with the relatively rudimental ceremony of speaker positioning. It is not even close to the subject of DPoLS but it is also greatly ne...

Yes, this sort of OT stuff is real drudgery; but unfortunately, it must be decided and implemented by the true OCD DIY Audio Guy for "best possible performance".The two options with respect to keeping the horn "conditioned" (temperature and possibly ...

Hello,I just logged myself in so first of all: Hi Everybody ;)Few days ago I aquired a pair of very interesting 3way horn speakers which seem, as I imagine, to ba an ambitious DIY project from the past. These are basically the Altec Vott A7 replicas ...

Romy, it is the UB horn that I need to first tune. Have found an earlier post of yours where you describe your process and will roughly follow it. First thing though is to measure an impedance sweep of the horn sitting in place to get the base line...

Hi Romy and othersI am in the initial stage of planning a new home, which will have a dedicated music room. I noticed Romy in another thread you were impressed with the rough stone walling. This looks like a great way to disperse reflections. What I ...

I have been looking in to mid bass horn designs to experiment with lately for the 4 way horn pa I am working on. As usual Good Sound Club always is on the Google search when dealing with any kind of horns. Although my reply to your post may be a few...

Moreart, if you ask my opinion then let me to decide what is relevant. Your idea of “how” your horn work is self-delusional in my view as whatever you imagine you do go overridden by deficiency of your mouths and by other problems that your enclosure...

I am not sure if the questions are wrong. Maybe they are just too early. There are plenty of audio people that pass around opinions as fact. That is a problem and most DIY pride is not in the absolute quality of sound, rather that it works, has wide ...

HI, Dietmar from Germany uses a diy multicellular horn for his JBL 077-tweeter http://chaudioroom.com/Photos/CH1505%20Dietmar-6m.jpg By the way, i´m searching construction plans of Altec 1505, 805 or 1005 for a complete DIY project. Any suggestions? ...

Hi Be,the thread is about the "bad" reputation horns have with "audio" people. Applying liquid dynamics gives them more fuel for the fire, that is why I avoid using stuff that really doesn't apply. We have no real flow of air or "turbulence" in a hor...

And as one of the other perpetrators...The nature of this kind of thing is compromise. The owner of the bass horn system wanted to run them together, for the enlarged horn mouth, and so we did - there was never going to be enough time to play about ...

If I think about the last 10-20 years, the only name that keeps coming up is Tom Danley. Synergy and Unity horns and tapped horn subwoofers got a fair amount of traction in the pro sound and DIY HiFi world. Just about everything else is “old technolo...

Moreart, somebody sent me this link last year. You are surely the DIY pioneer of back loaded Manger.As you probably know this is a touchy speaker to work with. Rated at 91 dB/W input by the factory, we measure ~91 up to near 92 dB/1W/1m in our two mo...

[quote user="Kcct82"]I didn't use John Hasquin's tapped horn design, I modeled my own in hornresp for my TAD woofer. I knew I would only need it up to ~55Hz so I was happy to have it flat from 23Hz-70Hz. The lowest crossover point for Behringer DCX 2...

I've only had the pleasure of listening to 'professional' horns (whatever 'professional' really stands for)--horn normally used in concerts and small venues. (It was always so obvious to me--by listening--that the range of the horn-loaded 'bass...

Hi Romy,
I have a DIY 8ft tapped horn taking up about 16" x 16" of floor space. From my experience it might be too short to go flat down to 20hz, you can make it "longer" by folding it more than once but it'll most likely end up bigger than 12" x ...
