[quote user="jessie.dazzle"] I might be totally wrong, but I just assumed that Vitavox's decision to specify a lower impedence voice coil for horn-loaded applications was related the additional load placed on the driver once mated to a horn, resu...

[quote user="Telstar"]Hi Romy,
Do you know something more about AMR new DAC? There is no mention on their site....I would be extremely interested on the results of such comparison.[/quote]Nope, I did not pursue it.

[quote user="jessie.dazzle"]I could not agree more. Above a certain price point, another thing that should be standard procedure is what Lamm has been doing since day one; and that is to establish a file for each component made, recording whenever p...

[quote user="jessie.dazzle"]I've been listening for about one week now with the filters set so the hand off from lower-mid to upper-mid happens higher up (upper-mid S2 is high-passed at 4800Hz instead of 3200Hz), meaning the small 400Hz horn is doing...

[quote user="jessie.dazzle"]I realize the question as to how you will get mid-bass (horns vs other solutions) is still open.
If you do go ahead with horns, you should be able to make them so that they'll accept most any 15" driver, which means...

[quote user="jessie.dazzle"]….. sit back and conclude that, yes, damn it, a pair of good straight Mid-Bass horns is exactly what you need. My reasons are of course somewhat selfish... as I won't like being alone in needing a non-digital delay solutio...

[quote user="jessie.dazzle"] Once I am done with more of this project, I will make a 330Hz Tractrix to try in place of the upper mid 400Hz. [/quote]
Hm, I wonder what would be the purpose to make 330Hz horn for you if you have 400Hz and a dedicated ...

Interesting, jessie
In my past I was trying to make my PC-based music server to act as CD transpire but whatever I did a dedicated CD transport sounded substantially better, in fact non contestably better. I used various software to read CDs, ...

[quote user="jessie.dazzle"]As for balancing the amplitude between channels by driving them from different taps: I drive the upper bass horns form the 16 Ohm taps, and everything else from the 8 Ohm taps. An 8 Ohm versoin of the upper-bass driver...

The pressure that builds up in right rear chamber is truly enormous.

Jessie,
Actually the tendency of manufactures to isolate ground becomes almost common among any more or less serious manufactures nowadays. The main’s ground is so polluted in US hat it is scare… or even dungarees. I remember a few years ago when I...

BTW, Jessie,
I have another solution for you if you have some extra space and… distance….. It is what I will do after I became a boring US suburban habitant… (BTW, it is not my RTD invention (Real Time Decupling) that implied in the mid of the threa...

Hi Jessie!
I’m probably suggesting the obvious, but have you tried adjusting the crossover component values on the fundamentals and MF-channels? On the fundamentals-channel, increasing the inductor-value, and decreasing the cap, so tha...
|
|
Yep, if I do it then I will do it right: with a single driver, with full length, with proper mouth, with slow profile and if it had curve then it will be properly linearly expending curve, not with the resonant chambers or with steps. The problem...

I recently completed some upper bass horns which I'm now enjoying very much. Sadly I lack the skills of someone like Jessie so my efforts are crude in comparison, but they are working well for me which is the main thing.I already had some old frontlo...

OK, now I am happier as I did my duty and the back chambers are ready to be attached to the horns and to be lifted up. Yesterday I spent 5 hours trying to build the back chamber displacement that Jessie and my carpenter ...

Jessie,
A few hints. If you are moving from Parsifal/Encore and LammM1.1 world into the world of SETs and Horn then do not be in hurry to commit yourself and do not create to yourself artificial addictions.
When I talk about artificial addictions I...

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...

Yes, Jessie, but in case you decide to go for DSET, would it be multi-channel Melquiades or anything else, then your consideration for type and topology of the lower bass would greatly dictate requirements for your DSET. If your lower bass channels r...

Hm, the 18mm out of 50mm in “fully in-gap mode” for Aura? It sounds too bad. The last time I touched this subject it was 6 years ago and I remember I had better impression in term of the numbers.

[quote user="jessie.dazzle"] "Short the ML2’s inputs and the hiss should be gone"
I assume it is not a mistake, and that you mean short the unused input on each POWER AMP (as opposed to the PREAMP).
