Jamo R909 Reference Speakers

Dipolar loudspeakers have existed for many years, but most examples have been electrostatic-types. While the sonic quality of these designs is often very good the main problem with this type of speaker is bass frequency reproduction is often compromised - they aren´t able to produce the characteristic physical bass ‘thwack´ in your midriff. To solve this problem, chief acoustic engineer Henrik Mortensen decided to use electrodynamic loudspeakers instead of electrostatic ones… the results were amazing.

“During the process we faced quite a few challenges”, Henrik Mortensen admits. “It was quite a task, to make an elegant and aesthetic design for a loudspeaker of this size. But I think we´ve succeeded with the Jamo Reference R 909… without compromising performance at all”!

With the launch of the Jamo Reference R 909 we offer you the opportunity to experience music, as it should be heard - live! This revolutionary new floor-standing dipolar loudspeaker employs two massive 15in woofers, a Seas magnesium midrange driver and a customized Scan Speak Revelator tweeter, all mounted in a 43mm thick baffle made of a unique multi-ply construction... this is a speaker that is set to change the face of the high-end speaker market.

The R 909 is the perfect match for the highest quality amplifiers on the market. However, with a high sensitivity of 89dB and offering a very stable load at 4ohms it doesn´t need a power plant to drive it… although it will handle more than 800 Watts of peak power if you really want to go there! The design and drivers used reproduce wonderfully transparent vocals and a response so dynamic that it´s hard to believe that you´re actually listening to a speaker. The exceptionally firm bass, blessed with immense transient speed, precision and fluidity throughout the frequency range (and absolutely no colouration or reverberation) simply puts you in the middle of the sound experience.

It may all be hard to believe it´s possible but a quick demonstration is all it takes to be convinced - sit down, take a listen to the R 909 and you´ll hear the proof.
