[quote user="Gregm"]Actually, that could be a viable commercial product: a "stereo am"p allowing for four channels. One hi side, one low side, per channel.Any moron purchasing this could be stratosphrically happy flabbergasting his pals by "passively...

[quote user="drdna"] The altered topology of DSET has the potential to have disadvantages. There is increased overall system complexity and this often seems to be a negative. Beyond this, it is difficult to expound, for me, on the specifi...

[quote user="drdna"] You are correct, though I believe the subwoofer covers only below 40 hz. [/quote] So??? [quote user="drdna"] This is coming from the same person who has built a 6-channel DSET? Anyway, it was more a thought about optimizing the o...

[quote user="decoud"]I know you do not want to do it, but it is a shame not to do it: actually manufacture a version of the Macondo with an integrated dset, cut down enough (say three channels) to make it feasible while still demonstrating the advant...

You can build DSET for anything. DSET concept does not imply any topology but recognition of purpose and accommodation of a topology for the purpose. Generally the 93dB sensitivity is not something that I would attack with SET, unless you use SET aro...

Yes, to “voice” the DSET is tricky and requires a lot of listening experience, or more accurately saying – it requires to make a lot of mistakes and understand own mistakes. It is not difficult –juts require patience. Still, if one “get” how DSET sou...

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...

[quote user="rowuk"]I have experimented
with SS/SET and now DSEP for ceramic magnet horn drivers. I will agree that
ceramic drivers with SETs that I have heard being suboptimal, but after a year
of DSEP, at least for my use case, I am quite conten...

Here it is, where the Cessaro folks should look and learn. Their cousins: The Berlin-based Martion Company produces Orgon system. The Orgon design and implementation are erroneous in many ways, however the Orgon system is 4-way playback with active c...

Hi Roman... you know "... but Twogoodears normally prefer a do not go to depth..." it's not an hide & seek kind-of-thing, but a necessity;-), as I'm not technical inclined or taught enough to discuss in depth of circuits designing... I'm only a u...

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...

user="anthony"]Hi Romy,
So it is time to think about the bass output
transformer in my DSET. My bass channel will be 8 x 25W/8565-00 each side
set in a sealed box and will cover the frequency range below say 100Hz.
These drivers can be ...

It took a LOT of time in CAD using what I had learnt from building the power supplies and then adapting it to match the requirements of the rest of the system. I have decided to mount the DSET on the horn stack and direct connect the speaker cables....

This morning I logged the mains power draw so that I can properly size the fuses.

[quote user="drdna"] The subwoofer still needs a substantial power source. Right now it is being driven by a solid state amplifier. It would be interesting to see what impact the SET could have here if any.[/quote]
I see, I did not know that ...

The “Enjoy His Music” published the old celebrated by many DIYers Herb Reichert’s article about his 300B amp ideas.

I read it before but reading it now, after a few years again...

My objectives when I wrote my initial post were not to knock the Herb Reichert’s design ideas but to demonstrate that DSET topology make most of Reichert’s views not applicable or even irrelevant. So, my post was not against Herb but rather to advanc...

user="Mike"] Originally the speakers were to be the
Verity Audio – Montsalvat speakers.…The Monsalvat require 3 pairs of

Ok, Mike. From DSET
perspective it is a fooli...

[quote user="Paul S"]I will eventually get another pair of ML2s to slave the bass/save the upper registers, because, as we all know by now, dedication rules. [/quote]
It wouldn’t be a DSET but rather just a simple bi-amplification. Bi-amplific...

Romy,A few months ago, iirc, you linked to a Canadian? amplifier which seemed to be made as or perhaps could be applicable for DSET use but I can't find the link. Can you remember where its is (or what it was called)?...

Hi Romy,I see why you don't like the design. And in particular, the choice of where he chose to limit the frequency responses for the two channels. I see the benefit of the DSET approach in this context as you explained it. If I understand you, your ...

I think the problem starts when we short circuit the process. It is easy enough to sell "the Best" of anything and still get mediocre results. If we are looking for a modular approach to DSET/speaker, then the results are also best guess because ther...

i am currently gathering parts for a pr. of full range melq.i would like to have the option to add a single stage to do 550 hz and up.then to switch the full range to do below 550hz.what transformer do you suggest for the high pass(i am ordering...

Something had changed very positively with multi-amping. I am not quite sure if it is because the full multi-amping of the specific of the implementation but it is what it is. The entire dynamic relationship between volume of a given tone and the ton...

I am very interested in your DSET adventure, and is trying to learn more about the application of adding crossover elements into SET amps. Looking at the schematic, I noted that you add first-order passive filters before the first stage of your...
