These are one of the best buys in monitor speakers. The 906 is not a “simply put together” speaker that had materials taken out from a parts bin. A lot of engineering and science went into it which saw the the speaker carrying JMLabs’ infamous “W” cone sandwich technology bass driver (which is one one of the brand’s most innovative product) and “Tioxid 5” inverted dome tweeter. Collectively, the two drivers worked in such synchronous harmony that the speakers magically disappears behind the music presentation. Music was very revealing, especially with vocals. Mid-range was one of the best from any monitor speakers and the highs were nicely detailed and smooth. These pretty weighty speakers will require a pair of heavy stands and some experimentation to sound their best. Good quality amplification is a must.
The speakers are easy to drive with a nominal impedance of 8 ohms. Sensitivity is 90dB and bandwidth ranges from 50Hz – 23KHz. Cosmetically, they are in very nice shape. The top of one speaker had a bit of paint touch up due to a bit of paint peel. Its not a scratch so the surface is still intact. Minor scuff marks can be found here and there. Speakers will be securely packed for safe shipping.
