The 8040B is a fully active bookshelf loudspeaker from Genelec, sitting above the 8030C within the brand's well-regarded 8-series with considerably greater internal amplification. The 8040B brings Genelec's more accomplished current professional studio-monitor engineering to a more capable active format.
Key specs that matter
Rated response is 41Hz to 25,000Hz within plus-or-minus 3dB, extending somewhat deeper than the 8030C. Internal amplification delivers 2 x 90W - considerably more than the 8030C's 2 x 50W. At 36.5 x 23.7 x 22.3cm and 9.4kg, the 8040B represents a considerable step up in scale and amplification from the 8030C.
Sound and use context
Expect more substantial dynamic performance than the 8030C, reflecting the considerably increased 90W-per-channel internal amplification and somewhat deeper 41Hz bass extension.
Pairing
As a fully active design, the 8040B requires no external power amplifier, connecting directly to a source component or preamplifier with line-level input.
Alternatives
Genelec's own 8030C sits below this model with more modest amplification for buyers wanting a more compact, accessible alternative.
