Less is more.
The Debut B4 harnesses the performance of Debut’s larger 2-way, bass-reflex bookshelf speakers and delivers it up in a compact enclosure that will have you guessing how Andrew Jones gets so much accurate, lifelike sound from such a tiny box. Use them as the perfect two-channel solution for smaller rooms, or as the building blocks for a compact surround-sound home entertainment system.
A family of performers.
Every Debut loudspeaker system establishes a value proposition—with build quality and spectacular performance—that goes beyond every other speaker in its class.
ELAC’s chief engineer Andrew Jones explains how Debut speakers break new ground:
“The ELAC Debut series delivers superior performance thanks to custom made key components, with no off-the-shelf parts. Unlike many more expensive speakers that mix parts-bin drivers, bare-bones crossovers and generic cabinets—every ELAC speaker is built from a clean-sheet design.”
Silk-dome tweeter with deep-spheroid custom waveguide
The waveguide surrounding the new ELAC high-frequency driver features a custom, deep spheroid profile to improve directivity control and shield the dome tweeter from cabinet diffraction modes inherent in traditional box enclosures.
Custom-designed woofer with aramid-fiber cone
Aramid fiber is employed in the woofers of all ELAC Debut passive speaker systems. Aramid fiber offers a superior strength-to-weight ratio and improved damping characteristics over conventional paper or plastic drivers. This added strength means arriving at designs that achieve a broader bandwidth with smoother response.
A custom multi-element crossover with high-grade components in each speaker ensures smooth transition between the drivers.
Every ELAC enclosure is engineered for the long run with thick MDF outer walls and a luxurious textured vinyl finish. The cabinets of the floorstanders and the center channel incorporate specially designed internal bracing to add stiffness and strength to the cabinet’s outer walls. This bracing greatly reduces cabinet vibration, which causes unwanted coloration to the sound. ELAC believes that the only parts of a speaker that should be moving are the speaker drivers themselves.
Superior build quality
Count the parts and look at them closely. These don’t look like the components that go in such competitively priced speakers, but rather, speakers that cost much more.
