Description
The JBL Stage 250B Speakers are the largest bookshelf speakers in the range, at 12.6” high. They feature a 5.25” bass/mid driver and a 1” tweeter. Additionally, there is a rear facing bass port that extends the frequency response down to 50Hz. The maximum power is 150 watts.
However, low-powered amplifiers can still achieve high volumes in a smaller room. The tweeter has a waveguide and the frequency response extends up to 25kHz. They can be used as the front right and left speakers or as surround speakers with the JBL range of AV receivers.
5.25” Polycellulose bass/mid driver
The bass/mid driver in the JBL Stage 250B Speakers is made of ribbed Polycellulose. This has improved distortion and damping Characteristics over paper cones. Traditionally speaker cones were made of paper pulp also known as cellulose. However, newer plastic materials are also now used. Particularly polypropylene.
This does not absorb moisture over time. Polycellulose is a combination of both materials and has the best properties of both. The ribbing also makes the cone more rigid.
1” aluminium tweeter
The 1” anodized aluminium tweeter sits in a waveguide. The waveguide is used to disperse high frequencies in the listening area. The theory is that a stiffer cone produces better ultra-high frequencies. Notably, JBL are experts at “voicing” a speaker.
A quality cabinet
The JBL Stage 250B speaker cabinets are made of audio-grade MDF. This rigid material has good audio characteristics such as resisting resonances. Moreover, good internal bracing provides solid mounting for the drivers. Additionally, as with most bookshelf speakers, there is a bass port that boosts the bass down to 50Hz.
Top-quality Crossover components
The crossover in a two-way speaker acts as a high pass filter. The JBL Stage 250B crossover is made of inductors and capacitors that split the audio band into two components. Audio-grade polypropylene capacitors are used along with wound inductors.
Previously the dielectric in capacitors was made of paper. This attracted moisture and caused the capacitors to go electrically leaky over time. Modern components will not drift in value or go leaky even over decades.
The JBL AV receiver and speaker range
The JBL Stage 250B speaker is part of a range of speakers designed to go with the JBL range of AV receivers. This comprises two sizes of bookshelf speakers, two sets of larger floor standers, a well-specified centre speaker and two upward-firing Dolby Atmos Speakers. There are also two sizes of subwoofers. JBL AV receivers are available to make 5.2, 7.2, and 9.2 systems.
Available in Espresso or Latte woodgrain finish with solid color front baffles and matching grilles.
