我没搞过障板,求交流,
下面是E文 邮件原文,
Dear Mr. WU XING HUI,
I transfer to you and with immense pleasure my experience and all my help for realize marvelous Dipoles.
The costs of project, realization and construction for the Dipoles are very low and fast to be built.
The ideal loudspeakers for realize marvelous Dipoles have :
- Qts from 0.9 or superior.
- High Excursion of Cone (+/- 4, 5, 6, 7 mm or superior)
- Low Frequences (Fs) of 30, 40 or 50 Hze.
This are the three more important parameters for get a ideal loudspeaker for utilize in Dipole configuration.
This are the parameters for the Woofers ... for a Mid-Woofer the value of Low Frequences (Fs) have small importance 70, 80, 90 Hze, the other parameters Qts and Excursion of Cone, to remain more and more high possible.
You look for Mid-Woofer in carbon - fiber with the parameters above and in little time I send to you drawing.
I make tests with loudspeaker of 165 mm and the result is excellent ... if you also find one with this measure, is all right !
We, in little time, have new preamplifiers and amplifiers.
This products not have buttons for ON/OFF, them make ON/OFF with signal in entry of only 1 mV/eff and when music to disappear for 40 seconds, every products in automatically go off.
For this new products (with valve), we want to insert small screen OLED or other screen to color (with possibility of programmed) where writes our logotype.
If you to find for we this good product, we purchase for discreet quantities from you and then, we give to you possibility of sell our products with your logotype ... as if this products are yours !!!
If you to sell our products with your logotype ... you have high gain $$$$ !!!
