[quote user="cv"]On the matter of the DHT having a plate resistance of 500-700... you do realise that running the 6E5p with an unbypassed cathode resistor is giving you an effective Rp of about 12k, right? The formula is, IIRC, Rp + (mu+1)Rk.[/qu...

hi Romy. Nice topic! I have a very nice memory. I started very young, supported by a friend who tought me a lot and gave me books to study. I learned the basic formulas and started DIY speakers from purely technical perspectives, graphs, math, calcul...

As the writer of the above-referenced propaganda, I am pleased to once again tweak the whiskers of the cat.
First off, this is promotional material so what the heck do you expect? Every brochure offers a new benchmark in performance or it is not doi...

Hi Romy,
Sunfire? No! Who would add a Sunfire to this system? The black box in the pictures a power amplifier for the midbass horn.
A second MF could be interesting. I will see if we can do some test set up of this. Per has the space for it...

suggest the thread to read about it ? So, how many octaves from fs will be
loaded properly ? [/quote]
How many octaves from fs? We are taking about how many fractions
of dB not octaves! Look for a threated:

Haralanov, do not write stupid posts, you have “no experience and no knowledge” about it. Also, do not propose to look at any other speakers as looking is very a deceptive activity. There is a phenomenon of vision that called “phantom visual reality”...

[quote user="Romy the Cat"]I do not care about all of Nilsson Pass amps; I feel that all the same and all are very sub-qualified. A few years back Mr. Pass went for his low-powered SS single-ended amps and they might be more interesting. The Cat[/qu...

I would agree that the Lowther is not hard to beat but the question is where and in whose mind does this competition exist? Is the Lowther, Manger, or other full range single driver in competition with different multi-driver approaches, other single ...

[quote user="Joe Roberts"] I feel I am being objective when I say that a Mirrophonic system simply blows away Altec, Vitavox, TAD, etc. [/quote]
Joe, I am not a reader of your magazine and the phrase like “blows away” impress me very little. P...

Joe, I think I would battle it.
I would not be so certain. Mostly the SUV sized bass horns are notoriously bad sounding despite of the assurances of the system owners overwhelmed with so common in audio endowment effect. Not to mention that the Stag...

[quote user="kodomo"]Hey Anthony,Your project is going on track (and looks like a very good track)! Just a reminder about the room acoustics. You are talking about bass frequencies which are as dependent to the room as the speaker! Before installing...

I chose the EdgarHorns for fairly simple reasons. I have listened to them and I loved the way they sound. They are not the perfect loudspeaker, but they make much truer music than what I have now. Also, the price I paid is less than...

Hi Romy,
I am planning my own DSET build. I have based my speakers on your Macondo and
am busy turning MDF horns in my spare time.
Once that is over I will move onto amplifiers. I plan to build a fullrange Melquiades for a
friend and the...

Regarding the "complexity" of these amps :
Not being a DIY electronics guy, the Melquiades schematic makes me want to reach for a cigarette... However, naive fool that I am, having no formal training in electronics, I look at it and think to mysel...

Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

Scott, I do not believe that people come to audio because the love of music. In fact the “love of music” itself is some kind of vaselino-chewee term that I would like do not use. An interest in Music has nothing to do with audio. I’ve been saying thi...

The Loudspeaker (Troels Gravesen project); a report started "too soon" because they've taken sooo long to build, and they fired right up (first try), and they already do Music!
