Compact Size With Big JBL Sound

One of the biggest advantages of the Stage 240B is its ability to produce a large and immersive soundstage despite its compact footprint.

JBL specifically describes the speaker as:

"The smallest bookshelf loudspeaker of the Stage Series."

Despite its compact dimensions, the speaker delivers:

• Wide sound dispersion
• Impressive bass response
• Detailed midrange performance
• Excellent vocal clarity
• Room-filling sound

This makes it an excellent choice for listeners who want premium sound without large floorstanding speakers dominating the room.

4.5-Inch Polycellulose Ribbed Woofer

At the heart of the Stage 240B is JBL's premium:

• 4.5-inch (114mm) Polycellulose Ribbed Cone Woofer

JBL specifically states:

"4.5-inch Polycellulose Ribbed Cone Woofer."

The driver delivers:

• Tight bass response
• Excellent midrange detail
• Fast transient performance
• Low distortion
• Natural vocal reproduction

The ribbed cone design improves rigidity while maintaining low mass, helping the speaker produce deeper and more accurate bass than many compact bookshelf speakers.

• Next Generation High Definition Imaging (HDI™) Waveguide

The speaker incorporates:

• 1-inch anodized aluminum dome tweeter

JBL specifically confirms:

"1-inch Anodized Aluminum Tweeter in a Next Generation HDI™ Waveguide."
