The Jubilees are breaking in now. Bass is much improved. I was using a +2 boost in the 40hz to 100hz frequencies but now they no longer need it. The biggest lesson I have learned about these speakers is they deliver a lot of excess mids which will pound a room into submission if they are not tamed.
I have never had a speaker which I had to cut the mids before. However the Jubes give out such a powerful midrange, they will drown out the treble and bass making the music sound muddied, convoluted, and just plain inaccurate.
Once I did a -3db cut from 600hz up to 3.5khz, the clarity and midrange definition really came alive. I love a prominent, defined midrange. However I don't like overbearing mids which overwhelm the treble so I like my mids slightly recessed.
However holding back on mids is a slippery slope. Too much mid trim and the midrange will sound recessed and distant. Not enough mid trim and the mids "shout at you" and overwhelm the treble and bass.
The Jubes have the strongest midrange out of any speaker I have heard or owned. And I love the three way configuration because I am not giving up treble performance in the higher frequencies in exchange for lower mid performance like I have been forced to do with my previous two way speakers.
These speakers will mercilessly expose any weaknesses up the chain such as a low quality dac, low quality recordings, low quality amplifier, etc. They sound their best in a open room at least 20 feet deep or bigger with high ceilings. They project a large wall of sound.
I thought the 510 horn emitting treble above my head might be a problem but it has been no issue at all. The mids and treble of these speakers envelop a room easily.
They sound great both on and off axis. I can't say enough how much I really, REALLY love these speakers.
They are definitely a worthy end to my long, expensive, and arduous speaker journey.
