[quote user="jessie.dazzle"]Do I understand correctly: AG used Fane 8Ms in the Trios upper bass horn?[/quote] Oh, no! AG in Trio’s upperbass horn used similar 8” driver with 103 sensitivity. That driver was bad and it made me to look for a replacemen...

[quote user="Ronnie"]The next big problem with sound here I think is a difference in sound level between upper bass and MF/HF.Upper bass seems louder (and ought to be). Would you help this electronics-handicapped guy to pad down the upper bass horn w...
|
JD,In the case of the mid-bass horn, the throat transition does not affect the sound enough to worry about IMO. Due to the narrow bandwidth (100Hz - 1000Hz) the step transition between the woofer cone and horn throat is acoustically invisible. I...

Since the 8M is now no longer to be had anywhere, for love or money (delighted to be contradicted on this), would people care to suggest alternatives for precisely the use Romy puts it to: driving a round, 3-4 inch throat, upper bass horn? I know it ...

I have been running around this design for a couple of months...I re-designed it just now to change some numbers according to your post. The main idea is to have a lot of posibilities in a huge horn:It is formed by conical sectors th...

I've been having love/hate relationship with Lowther (and its siblings) for several years now. As you all say, it has many problems to use as a full-ranger. Right now, my set up is a 3way multi-amp, Lowther (Reps 1) in Medallion cabi...

How did you determine that it is the horn. What makes you think that you can damp a horns mouth at 200 Hz. Have you never read what a room does to frequencies under 400 Hz? If not, check this site out: http://amroc.andymel.euMaxx, I think that you ar...

[quote user="Jorge"]Andrew,Dont buy all the drivers at once, I would get only the upper bass horn drivers and maybe the mid drivers, you will have to play around with these for a while before things start clicking toghether, by then who knows, ma...

The Delta Pro-8B looks like a very fine driver, in fact on the paper it is even better then Fane (with exception of sensitivity and inductance) The problem is that no one knows how this driver will sound until it is loaded into a specific horn, no o...

I still remember proposed solution for symetrical TAD 1201 horn loaded midbass sections. Was it to free listener from sweet spot low seat position ? I could imagine that that midbass horn performing up to 1000Hz sitting low on the floor would impair&...

I understand your recommendation and agree. I need to have upper bass and MF and than see how to merge fundamental channel in between.So, I better postpone experiments with compression drivers and only compare 12" Supravox in two horns: 42Hz 2m long ...

[quote user="Jorge"] Once you have an Upper Bass Horn working properly with a good driver inside it, and getting at least 6 db extra output out of the loading (I just wrote about 2 pages of technical difficulties on this but let’s just stick to the s...

Here are some photos of Martin Sedon's 204Hz and 340Hz Le Cleac'h horns, which likely have more reasonable shipping charges and fit through doorways, etc. better than the 160Hz version. They have a T-factor (expansion rate) of T = 0.8, which was reco...

I gave another run to Vitavox S2 with electromagnet and while I was listening I come across to an interesting observation. I screw the S3 in 330Hz horn and was trying to run it with 500Hz crossover point. It is pretty standard configuration, the way ...

Herman, I am glad that you feel better about sound from your midbass horns. I do not know what damage digital amps incur but even your experience of hating the sound of those horns to falling in love with them just after changing the amp do suggests ...

Jessie, there is another solution that you might consider, that might be viewed as compromise for one-side as might not be view is compromised from other side. If to allowed ourselves to close eyes to midbass timing-integration and if the geography o...

Hi Romy,
Well firstly on those, the tweeter is not offset to one side - it appears to be time aligned directly behind the midrange horn and upper bass unit. Secondly, that's a JBL 2405....

This subject of digital crossovers became quite popular during last few years and many audio-people give up and go for a simplicity and painlessness of digital crossovering. There is an army of people out there who would swear by a complete transpare...

It seems like I should just abandon the idea of using the Druids... and trying to get some sort of coherent integration with my WB-Chimeras (acting as the lower- and upper-bass units)... and running the whole hodgepodge with totally different amplifi...

I never was fan of the Oris 150. They meant be used with Lowther type of drivers, that never worked properly. The Oris 150’s upper bass is not really the bass that might be obtained form the Oris’ mouth. Should this Oris has twice smaller throat and ...

I wish I could pin-point the frequencies and explain the effect better. I'll do my best.I want to cover my ears when a Pavarotti sings certain higher notes or some notes when Caballet sings pretty "comfortably".It's like bad PA horns or horrible acou...

IME (i.e. some pm's one dx), the Ex-4 sounds the most civilised -- and this, only up to ~10kHz or 1-2kHz lower.It doesn't sound bad in a tractrix, unlike Paul S' experience with a dx4.A horn is also useful to provide some extra spl (106 spl at 1+m wi...

[quote user="RonyWeissman"] I have the 515-Gs If I remember correctly, and I am trying to find suggestions on what is proper horn-loaded cabinet still. And I agree my tannoy golds so far have worked best with early 70's mcintosh 22...

[quote user="Jorge"] Lets just say that TH bass is much cleaner and generates a different "bass sensation" in the room. Once you get used to it, it is very difficult to go back to boxed bass.I find the sound similar to what a Mid bass horn woud pla...

[quote user="Romy the Cat"]As I said above your you "experienced today with GOTO" is just your transitional
feeling and you will change this feeling many times. To accommodate a pair of 42Hz
horn in a system is a year-long project otherwise you ge...
