FOCAL 165K

The details are clear

FOCAL is a product of another brand, one HI-END level sound home. The cars are well known. Which is the largest caraudio speaker manufacturers in the world. Which is dedicated to producing sound from the sound distribution throughout the world. It made several versions of most models is the Utopia Line and the version we will be tested in a minor version of the model code Polykevlar Line.

More attractive.

FOCAL caraudio speaker series was 165 K Component 2-way caraudio speakers with 6.5-inch woofer and a 1-3/4 inch caraudio speaker TWEETER lasting power is 80 watts (RMS) and a maximum of 160 watts (MAX) Impedance 4 ohms. Frequency Response 50 - 20,000 Hz Sensitivity 93 dB (2.83/1m) with Network News. The grading of high-quality equipment to use. With the device for installation. And a good caraudio speaker. It all comes packaged in a red color logo, one-off Bond.

Characteristics of the woofer, a 6 ½-inch by 6 K1 Model Material cone woofer made of a poly's Cave, NY. The caraudio speaker is a flexible rubber VOICE COIL 1-inch high-quality magnets. And covered with rubber cushioning. The characteristics of the Model Code TN 45 TWEETER INVERTED TITANIUM made from the VOICE COIL 100-watt high power, high sensitivity, 92 dB (2.83V/1m) frequency response of 3 k - 20 kHz, with Phase plug and magnetic. Neodinium, VOICE COIL 20mm size, liquid-cooled magnetic material and FERROFLUIDED Network Links 2-way code generation FA K2 HIGH-PASS has been designed. And grading equipment, as well. The average slope of 18 dB / oct. The cut-off point at 3.5 kHz with a switch that adjusts for TWEETER 0, -2, -4 dB.

The T / S Parameter from Fs = 64.4 Hz Re = 2.92 ohms Qes = 0.69 Qms = 10.27 Qts = 0.65 Mms = 10.5 grams LVC = 0.38 mH Xmax = 4.75 mm Sd = 132.7 cm ^ 2 Vas = 14.4 L BL = 4.2.

Tested in the LAB.

BURN IN After successfully. I tested the TWEETER by measuring the value of Re (DC resistance of VOICE COIL) by measuring Om John Mitchell's precision with the value Re = 4.7 ohms, the measured values ​​IMPEDANCE caraudio speaker TWEETER which with the IMPEDANCE 8.034 ohms minimum 5.4 ohms maximum, and average of 5.64 ohms, which is the T / S PARAMETER is Fs = 2.36 kHz Qms = 3.84 Qes = 5.4 Qts = 2.24 Le @ 1kHz = 0.415 mH, Le @ 10kHz = 0.07 mH.

The subwoofer has a value of Re = 3.0 ohms, with the IMPEDANCE up 38.09 ohms and a minimum 3.568 ohms, and the average is at 8.677 ohms, which is the T / S PARAMETER is Fs = 71.36 Hz Qms = 8.54 Qes =. 0.73 Qts = 0.67 Vas = 10.45 liters dBSPL = 89.13 SD = 0.0139 m ^ 2 no .= 0.4993% Le @ 1kHz = 0.6469mH, Le @ 10kHz = 0.270mH, Bl = 4.86 Tm, ADD MASS = 40g Mms = 12.82 grams.

The sound quality.

To test the caraudio speakers, FOCAL model 165 K can be installed in the car TOYOTA COLOLA model KE-70 with the source radio - CD of the JVC model KD-SX650 is an input signal into the power amp POWERAMPER Model PA-150. FOCAL caraudio speaker for this version by installing the door panel test And adjust the crossover of TWEETER at -2 dB and then measure the frequency response curve of the system by the use of CAR METER AND RTA inspection phase of the system in phase with the PD-5.
The output from these tests provide clear sound FOCAL. And filled with great detail and depth and soundstage still have not spread the dimensional direction and the position of a piece of music more easily without the need to concentrate on listening to too much, it can recognize the sound clarity is achieved. streaming audio, the acoustic bass is heavy and compact caraudio speaker must recognize the true HI-END.

Summarize

For the HI-END FOCAL caraudio speaker is not an absolute standard and quality of care in production. Grading equipment. Everything to be perfect. For those interested. You can try to listen to the machine shop, a leading voice. For more information or to V. C. Audio (Thailand) Co., Ltd. Tel .0-2690-6006-7. 2690-6007 or fax :0-http://www.focal.tm.fr.
