My experience is that I do not "hear" the super tweeter when doing a frequency sweep. I just hear what it does to instruments like trumpet, percussion, violins, piano, oboe. Those instruments have an appreciable portion of "articulation" to get the individual notes started and the general "close ...

I think that this is worth looking at. Setup AirPods for hearing assistance and/or music all in one device.

Why would this be different than just using the weather stripping and leaving the transformer bolted to the bottom

Just guessing, the bottom of the box may be more rigid than the top as its supported by the sides and corners, also attaching the transformer to the top will increase the moving ...

Bolt the transformer to the lid instead of the base with rubber grommets or O-rings between them and the lid for damping. Screw the lid then to the rest of the box with some weather stripping on the edges to insulate/isolate.

Hi Rowuk, can you point us to which 834P clone (for MC I hope) you built?
Thanks
Adrian


it was this one:

Several things come to mind - especially the valve kits available on eBay. I have an original EAR 834 phono preamp and also built one of the clones. The clone is as good! I also see some Audio Research clones. If you want to just build something with point to point wiring, the Dynaco PAS2/3 had a 2 ...

I would offer to use parallel output tubes. That would reduce primary/secondary by half.

When I see builds like this, it reminds me of the late 1970s and early 1980s with those magnificent huge receivers from Kenwood, Pioneer and Sansui. They were not just big boxes, they were full.

My opinion is that a "magnificent" build like this should also get a big, statement box so ...

I also use the HF146 that worked fine at 300 Hz with a 66cmTractrix horn. In the mean time I replaced the "large" roundover with a wooden ring (horn now 55cm) and now cross over at 450 Hz with phenomenal results. This driver is a keeper and 300 Hz was no problem - even with the distortion curves. A ...

I use Malwarebytes.

I would only be careful of russian (Kaspersky), chinese (don't know of any) or Elon Musk connected software.

MacKeeper behaves in ways that I do not tolerate.

I often why Daniel is so abrasive - maybe just because he can? I also question what difference a contract makes when considering a cloud space to be someone elses computer. In my world it is none. It is still someone elses compiuter (or space running on maybe even a third parties computer - also ...

Regardless of the details, as Nick stated, the cloud is just someone elses computer at the other end of an IP pipe. That means that they ultimately call the shots about everything that happens with that remote computer - regardless whether it is access to a service, a platform or infrastructure.

I ...

I would say, just try it. If it hums, you know that there is a ground loop to deal with. If not - proceed to the enjoyment stage.

What we do not know: is this for your home audio, or for PA purposes.

I often wonder why symmetrical connections (other than transformer coupling) are of any interest ...

And now the tweeters
Thanks to John Carlson and his Karlson Couplers Beyma CD-1ND drivers

In actual use, Jon will likely be around 2m from the speakers, and approx 3" down from the tweeter axis. So, I did another final measurement to represent that. I think this one used 1/6th-octave smoothing , bearing in mind that was just one measurement. As you can see, the slight rise to 10kHz has ...
