Short answer: the Genelec 8361A for better sound quality, the Genelec 8040B for the lower price. The Genelec 8361A ranks #5 of 40 powered bookshelf speakers at $10900. The Genelec 8040B ranks #9 at $2350, $8550 cheaper.
What the Genelec 8361A gets right: Three-way coaxial design: 5” mid-range with an inset 1” metal dome tweeter, flanked symmetrically above and below by two 10” front-loaded woofers. The catch: Approximately $11,000 per pair; Genelec’s GLM room-correction add-on (measurement mic plus software) is another ~$450 and wasn’t used in this review.
What the Genelec 8040B offers: Based on their smaller speaker’s performance against others, I’m ranking this accordingly. Watch for: Very expensive.
Buy the Genelec 8361A if sound quality matters more than the price. Buy the Genelec 8040B if the price matters more than sound quality.

The Two Speakers In Full
Genelec 8361A: $10900 Bhphotovideo
Pros: Three-way coaxial design: 5” mid-range with an inset 1” metal dome tweeter, flanked symmetrically above and below by two 10” front-loaded woofers, giving nearly identical vertical response whether you’re sitting or standing. Wide, consistent horizontal radiation of about ±60°, very forgiving for multiple seats or a home-theater row. Distortion at both 86dB and 96dB/1m stays below roughly 1%, and multitone distortion is also under about 1% - among the cleanest speakers reviewed. Long-term compression is practically non-existent, with no woofer bottoming or audible intermodulation even driven to 90dB+ at 10 feet. In-room bass extension reaches down to about 35Hz without a subwoofer. Extensive back-panel tuning (bass rolloff, bass profile, treble profile, and a desk/console compensation switch) for boundary placement.
Cons: Approximately $11,000 per pair; Genelec’s GLM room-correction add-on (measurement mic plus software) is another ~$450 and wasn’t used in this review. Shows an on-axis dip around 200Hz that may be tied to some rear-panel radiation or resonance the reviewer couldn’t fully explain. In far-field listening there’s a mild upper-midrange/lower-treble rise (roughly 2-3kHz) that only smooths out with 5-10° of toe-out or closer near-field placement. Short-term compression testing shows some tweeter limiting, though it didn’t translate to audible issues in real-world listening. At about 70 lbs, awkward to lift onto a stand alone.
