JBL STAGE 240B Plaukta akustiskā sistēma (cena par gab.)

The JBL Stage 240B bookshelf speakers feature a 4.5-inch polycellulose ribbed cone driver and a one-inch anodised aluminium tweeter, ideal for audiophiles seeking high-quality sound in a compact form. The Next Generation HDI waveguide ensures precise sound dispersion with reduced distortion, letting you enjoy your music in more lifelike detail. Despite their size, these speakers achieve greater low-frequency performance thanks to a bass reflex design and rear-firing tuned port, making a little go a long way.

4.5” punchy bass/mid driver

The bass/mid driver in the JBL Stage 240B speaker features a 4.5” Polycellulose ribbed cone. Speaker cones are normally made out of paper pulp or Cellulose. However plastic materials are also now being used. Notably polypropylene. This material does not absorb moisture and can produce less distortion.

The cone used in the JBL Stage 240B speaker is made of a combination of both, known as Polycellulose. This has improved rigidity and damping characteristics. Lastly, the quality tweeter is made of anodized aluminium and sits inside a waveguide. The waveguide ensures good dispersion of high frequencies.

A quality cabinet

The cabinet of the JBL Stage 240B speaker is made of MDF which has good audio characteristics. The internal bracing reduces resonances. Moreover, the rear-facing bass reflex port boosts the bass with this compact speaker. There is also a removable front grille. Bass ports are used by smaller speakers to increase the bass response. As a result, the bass is extended down to 48Hz.

Crossover

The crossover used in the JBL Stage 240B speaker splits the audio into two bands for feeding to the tweeter and bass/mid unit respectively. It is essentially a high-pass filter that is made up of capacitors and inductors. The capacitors used are high-quality polypropylene types that do not go electrically leaky or change value over time. The crossover frequency is 1.4 kHz.
