The Western Electric L-9 in Munich was/is an infinite baffle design. The 754B woofers are in a sealed enclosure with a front horn. There is no possibility of cancellation between front wave and back wave of speaker, so I wouldn't call it an "open baf...

[quote user="Paul S"] I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the ...

Ok, it is a lot of information on my plate and I am trying to make sense of it. Below I will share my observations about the new Pure Power 3000+.

I actually read the review carefully.

[quote user="rowuk"]How many sources do you currently have? If you are building a phono corrector, make it for 4 volts output. If you have a PC for digital playback, there are good DACs with more than 2V output. That would leave a tuner to pimp - cer...

Two of my local audio folks asked me to put online my thoughts

An amazing event took place during the flip between 2011 and
2012, the New Year nigh. It was my former suburb listening room, the one that

I frequently was...

Pham’s installation did pop up at my site before, primary in context of the illustration of what “those brainless Goto people do”. During the last year or two Mr. Cuong made some changes that I feel worth to note and to discuss.

[quote user="el`Ol"]Romy,
I find the Veravox 5 drivers are strong contenders when searching for elevated sensitivity 5" drivers. I heard the Veravox 5X in combination with Shindo SET electronics and found it very natural-sounding. Both 5ers have cer...

This is very interesting subject that gave me a lot of head ache until I figured the things out.
It is known that I have aversion to ground that comes with mains. It is very dirty, so a few years back I drove 15 feet copper poll in pretreated backya...

[quote user="haralanov"] So the tweeter is always needed. The bad thing is it deforms (in 99,9999999999999999999% of the cases) the perfectly round audio window, formed by the midrange channel and "pull" some notes sometimes at its axis. These are of...
