Product Description
The JBL Stage 240B Speaker is a compact unit that is around 11” high. It features a 4.5 bass/mid driver and a 1” tweeter. Moreover, it has a rear-firing bass port for punchy bass. The recommended maximum amplifier power is 125 Watts. Additionally, low-powered amplifiers can drive this speaker to high volumes.
The frequency response extends up to 25 kHz. Notably, This is the smallest speaker in the range and is good for the main left and right speakers in a small room. They can also be used as surround speakers with JBL AV receivers.
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 qaulity 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.
The JBL AV receiver and speaker range
The JBL Stage 240B Speaker is part of a range of speakers designed to go with the current JBL AV receiver range. There are two sets of bookshelf speakers that have stands available.
