Или рации у военных. Тоже визжат - зато на поле боя всё слышно.
Кстати, вспомнил (кажется, это было то ли в Радио, то ли в Науке и Жизни, лет 30 тому назад) цикл статей про звукозапись, про то, в частности, как подзвучивают задние ряды концертных залов. Излучатели с узкой направленностью. Чтобы первые ряды их не слышали, а "галёрка" - воспринимала. Никто поподробнее не вспомнит? Автор статей - как сейчас помню - был Ю.Козюренко.

Dear Mihail,

For me it was the same; in the past I visited many times Russia and until now I had only a few contacts with Russian audiophile people.

Regarding you questions the following:

- The white surround on the EMS driver LB12EX field coil units in the Grand Crescendo Appassionata is made of thin goat leather; the spider is made of 0,8 mm Birch plywood.

- In 1996 I visited Bernard Salabert for the first time and since then we represented his PHY-HP company until May 2011; the date my dear friend passed away and this made me very sad because he made such wonderful wide range units

- Since August 2011 we represent the French company EMS (Electro Magnet Speaker) and I am still impressed by this little company and the very nice high quality units they produce. The field coil units I like most and Michel Fertin is making them since 1968 and he is a very experienced loudspeaker designer. Mr. Michel Fertin visited us several times and we asked him of course his permission for our modifications and he was enthusiast about our work and he proposed us to order the units in parts so we can modify and assemble them to our own design

- If you have a look on our website www.musicalaffairs.com and you click on "Producten" and after this on "Grand Crescendo" - "Grand Crescendo Appasionata" and "Mini baffle" you will discover some pictures of our loudspeakers

- The newest developments we are working on are:

The Baffle One: this open baffle loudspeaker is equipped with two EMS Fieldcoil driver units. The upper one is a modified LB12EX wide range high efficiency "field coil" unit. The modification consists of a new designed spider en it is a so called "surround less" unit. The surround less unit is incredible; we removed the surround and this is a very nice modification!

The lower unit is a modified B15EX high efficiency woofer. The modification: we replaced the surround by a goat leather one and the spider was also replaced by a modified one. There is no tweeter and all the high frequency is done by the LB12EX
Listen to these videos:
https://www.youtube.com/watch?v=Q5erRFJv3Zg    listen to one!
https://www.youtube.com/watch?v=fHu7Jv7FaNQ    certainly this one - all the high frequencies from the 30 cm driver!

A new cabinet speaker equipped with one modified B15EX and a "surround less" unit type LB7EX On the video I old the tweeter should be a MA%EX but we changed this into the LB7EX - see https://www.youtube.com/watch?v=GxwGGU18WEE

- You asked me about the amplifiers we use: here are some pictures: picture 105 and 106 show the preamplifier and picture 958 shows the Monoblock power amplifiers; these amplifiers are equipped with Tamura transformers, Emission Labs tubes; 2 pc 2A3 Mesh in "push/pull" and the EML 20A Mesh as driver tube

I wish you lots of viewing- and listening pleasure and I hope to hear very soon from you!

Best regards,

Hans
