Band: opinion spread · Dot: weighted average
Sources split almost evenly. The Headphone List, Pokde, nloop, EnosTech, EFTM and Digital Reviews hear a warm, smooth, well-balanced speaker, and Hardware-Helden hears a mild smile curve that is fun for games and music. ASR's Klippel measurement of the R1280T shows two resonances and a jagged response, and Amir heard it as a bit bass-heavy and then bright. Several owners hear the same thing: bass-heavy and very bright with the dials flat, harsh, or muddy and dead. Amazon's sound mentions run 984 positive to 127 negative. Owners who like it after adjustment usually turn the bass down and the treble down or up.
Measured
Klippel NFS (ASR, R1280T): a jagged on-axis response with a woofer resonance near 5 kHz and a tweeter peak near 10 kHz; spinorama.org computes a deviation of 5.5 dB over 300 Hz–5 kHz and a preference score of 2.41 (5.02 with an ideal subwoofer, 5.41 with EQ). wwenze's in-room and close-mic measurements of the sibling R1280DBs show extra level at 100–200 Hz and about ±4 dB of treble variation.
vs. listeners — Warm-and-balanced reviews sit against a clearly coloured measurement. Amir himself found the flaws 'subjectively much less' than the graphs suggest and says turning the treble dial down makes it quite listenable, which is what many satisfied owners do. The measured unit is the R1280T; most reviewers say the DB sounds identical, but Pokde heard the DB as clearer with deeper bass.
“The R1280DB has a warm, smooth low-end combined with a little extra treble crispness.”

“any hope we had of this being a "studio monitor" with flat response is thrown out the window”
