JBL 4344MKII

Commentary

A refined model of reference monitor 4344 developed under the theme of low distortion rate and wide range reproduction.
It provides a wide and smooth response while maintaining the overwhelming dynamism.

For low range, it is equipped with 38 cm cone type woofer, ME150HS.
A high-rigidity fiber composite cone is used for the diaphragm. This cone has an appropriate damping by applying an Aqua Plus coating on the surface. It has a built-in SFG (symmetrical field geometry) magnetic circuit that drives this diaphragm with a symmetrical magnetic field and low distortion.
In addition, it is equipped with a unique bent gap cooling forced cooling mechanism to realize excellent transient characteristics and low strain rate.

It is equipped with 2123H which is a 25 cm cone type unit for middle and low band.

Driver unit 275 nd of 1-inch throat is mounted for middle and high range.
Neodymium magnet is used in this unit.
We have also improved the shadow effect by increasing the sense of unity between the horn and acoustic lens, and achieved clearer sound localization.

For the high frequency band, it is equipped with an ultra-high fragile driver 2405H which adopts a ring radiator.
The system is highly reliable and able to generate continuous and high-power signals exceeding the audible range.

The network section uses separate boards for the low frequency band and for the middle and low frequency band to prevent interference between the bands.
A charge-coupled linear definition network, which operates class A after applying a bias to a capacitor, is adopted for the network circuit for middle and low frequencies and above, eliminating the generation of 0 cross distortion.
It also supports bi-amp drives with channel dividers and bi-wiring connections.

Equipped with an attenuator volume that can adjust the output sound pressure level of each unit for mid-low range, mid-high range, and high range.

The enclosure uses a bass reflex system.
The plate is made of the same high-density MDF material as K2 series.

A large binding post is used for the speaker terminal, which is compatible with very thick cables.
