Custom Designed Transducer - The high power output woofers deliver well-defined, powerful bass with minimal distortion, while the 1.4" precision compression driver* produces accurate mid-range and high frequencies. Volume in decibels decreases by 6 decibels for every doubling of distance. The further away your audience is from the speaker the more volume you’ll need.

I/O connectors INPUT1: Combo x1, INPUT2: Combo x 1 + RCA pin x 2 (Unbalanced), OUTPUT: XLR3-32 x 1 (CH1 Parallel Through or CH1+CH2 Mix) High-Efficiency 1000W Class-D Amplifiers - The DBR's lightweight, high performance Class-D amplifier is capable of producing up to 1000W* of power, achieving an SPL of 132dB, delivered with remarkable clarity and dynamic characteristics. If you are a solo acoustic or duo act, don't even hesitate. These speakers sound every bit as good as the DXR and K series in that environment and for substantially less money. In a band situation remember that these are 10" speakers, so for smaller bands and smaller venues it will handle it quite nicely, but don't expect these things to cover a huge club... they were not designed for that. Yamaha use their own custom bass driver, comprising a two–inch voice coil and a 10–inch cone. This sits beneath a one–inch, horn–loaded compression driver, and both the tweeter and the woofer are protected by a perforated steel grille. A DSP is used to handle the crossover (an FIR filter) and speaker management functions, and the crossover frequency is 2.1kHz.DBR speakersutilise the latest technology and speaker designs to get that fantastic performance, including Digital FIR-X tuning™

The cone is placed beneath a horn-loaded compression driver about 1 inch in size. A perforated steel grille has been used to protect the tweeter and the woofer. A DSP is utilized to deal with the crossover and speaker capacities. The cross-over (an FIR filter) is of 2.1kHz. DBR Series powered loudspeakers harness the same state-of-the-art Yamaha DSP, amplifier and speaker technologies developed for the professional DSR Series and DXR Series lineups, ensuring high-resolution sound at any output level. High-Efficiency 1000W Class-D Amplifiers Soundwaves change based on various elements. A crowd of people can diminish how loud the music sounds. Other obstructions like walls and furnishings can also diminish the volume. I had been planning to get the DXR10s but took a chance on the DBRs -- which are 1/3 cheaper. Although I think the DXRs would be a bit more versatile and capable of filling a larger room with sound, for my purposes I'm glad I saved the money. (I could've saved a little more by skipping the sub and going with a pair of DXR15s, but then I would've lost grab-and-go versatility.) I"d been playing acoustic guitar through a small acoustic combo amp, mostly doing solo "special music gigs." I"m generally not playing longer gigs, just a few songs for special events. I"d been happy for the most part with my small amp. Considering everything, it"s quite capable, especially when playing solo to a captive audience. I"ve had more than one occasion however when I turned down requests to play in a larger church or with a small ensemble. In those situations, the amp is less than adequate. I could be heard throughout the church when playing for a quiet crowd, but it just wouldn"t fill the room sufficiently. I should also make clear that I am not a fan of "DI-ing out." I"ve played in churches in particular for years. I"ve been burned on too many occasions to be comfortable with that.Smart Enclosure Design for Floor Monitoring - DBR Series speakers feature an optimized 50°wedge angle for floor monitoring. In addition the DBR12 and DBR15's symmetrical shape allows for effortless configuration of a mirror-mode floor monitoring system in either symmetrical or stereo sound field setups. The new DBR series makes the technology from Yamaha’s established DXR speakers available at an even more wallet–friendly price.
