MK12

12-Inch 2-Way Full-Range Loudspeaker System

MK12 is a 2-way full-range loudspeaker designed by JBL for KTV boxes. It uses a 12” woofer and two 3” tweeters to realize exceptional acoustic performance – high power, low distortion, and remarkable electro-acoustic conversion efficiency.

The 12” woofer is specially designed for high power handling and features a non-pressed long fiber pulp cone with foam surround, which provides enough stiffness and reliability while processing the electromagnetic force. A demodulating aluminum ring is fitted to guarantee minimum distortion and power compression. For the high frequencies, two 3” paper cones are installed, in consideration of their light weight and, most importantly, their ability to reproduce high notes bright, smooth and with excellent dispersion.

To optimize power distribution between low and high frequency transducers and for better frequency response, a precision-engineered crossover is utilized. The cabinet to support the tweeters is built in a V-shape so as to further improve the coverage and sensitivity, two factors essential to a karaoke speaker.

MK12 presents itself as a mix of edgy design and high tech through its light-coffee palette, wave-like front grille, and luminous JBL ENTERTAINMENT logo. The light-coffee colored enclosure is constructed of premium quality MDF and finished in durable vinyl wraps. Two high-strength M10 suspension points are provided for bracket mounting. 16-gauge steel is used to build the corrugated grille and to protect the components inside. JBL’s PSL (Passive Sound Lighting) Technology is what’s behind the glowing JBL ENTERTAINMENT logo and making JBL sound visible.

12英寸雙向全頻揚聲器系統

MK12是由JBL為KTV包裝盒設計的雙向全頻揚聲器。它採用12英寸低音揚聲器和2個3英寸高音揚聲器，可實現卓越的聲學性能 - 高功率，低失真和卓越的電聲轉換效率。 

12英寸低音單元專為高功率操作而設計，採用無壓長纖維紙漿錐體和泡沫環繞，在處理電磁力的同時提供足夠的剛度和可靠性。安裝了解調鋁環，以確保最小的失真和功率壓縮。對於高頻，安裝了兩個3“紙錐，考慮到它們的重量輕，最重要的是，它們能夠再現高音，明亮，平滑且具有出色的色散。 

為了優化低頻和高頻傳感器之間的功率分配以及更好的頻率響應，採用了精密設計的分頻器。支撐高音揚聲器的音箱採用V形設計，以進一步提高覆蓋範圍和靈敏度，這是卡拉OK揚聲器必不可少的兩個因素。 

MK12採用淺咖啡色調，波浪狀前格柵和明亮的JBL ENTERTAINMENT標誌，將前衛設計與高科技融為一體。淺咖啡色外殼採用優質MDF材料製成，並採用耐用的乙烯基包裹材料製成。兩個高強度M10懸掛點用於支架安裝。16號鋼用於製造瓦楞格柵並保護內部組件。JBL的PSL（無源聲音照明）技術是發光的JBL ENTERTAINMENT標誌的背後，使JBL聲音可見。
