LM-3 Loudspeaker

Field Coil Version

 

Line Magnetic’s flagship horn speaker, the LM-3 follows the design concept of the classic Western Electric Horn system.

Line Magnetic Audio is a brand of High end products founded in 2005. Now it has become well known with its series reproduction of music and regarded as a forerunner in presenting innovative products with cutting edge technology and lasting intrinsic value. Tube electronics, CD players, Classic horns, Classis field coil speakers, DACs, a lot of different series of products we are working on not only Classis electronics but also new technology on dacs and CD players. The LM-3 are exceptional speakers. The pavillon and its medium driver are replicas of the famous Western Electric 22A and the Western Electric 555W. A reproduction at the antipodes of the hi-fi with an extremely natural sound of great magnitude. The bandwith extends from 150Hz to 13kHz. In the bass, an 18-inch speaker, the TA-7376 founded in a low-reflex load. Finally the treble is entrusted to the LM-302, replica of inspiration Jensen.

The result is amazing : An input sensitivity of 105 dB for an impedance of 8 Ohms.

The LM-3 Field Coil version combines the following drivers:
Tweeter:                             HT-70CU (Horn version)
Mid-Range:                       22A Horn and 555 (Field Coil Version)
Woofer:                             TA-4181 (Field coil Version)
Crossover:                         TA-7376
Power Supply:                   PR-22

Specifications:
Frequency response:         38Hz~20KHz
Input sensitivity:                 105dB
Power:                                100W

The PR-22 Three Way Field Coil Power Supply is an adjustable tube rectifier low voltage field coil power supply, specifically designed for low voltage, high current application of field coil drivers. It uses a low voltage tube as the tube rectifier for the power supply.

The main circuit concept of the PR22 follows the Western Electric WE4144 design. Output voltage is from DC 7V to 24V. It can also be used as a power supply for WE, RCA etc drivers.In order to monitor the current during adjustment there is a meter installed on the front so that you can monitor during adjustment.

PR-22 Specifications:
Input Voltage Range:       220V~240V/AC 50Hz~60Hz, 100V~120V/AC 50Hz~60Hz
Output Voltage Range Three Steps:
LOW:                                 DC 10-24V / 0.5~2A
