Borreson X2

I have heard them and a fine sounding loudspeaker ,the only downside 

is the smaller bass drivers at least if these were 8 inch drivers would would pressurize the room better it isa very deep speaker but 5 inch ,I wrote to them a 7 inch driver would have been much better  ,the bass is very tuneful to a honest upper 30s it rolls off fast upper 30s is more honest. That being said very open and musical 

you are missing over a solid octave of Low Bass  for many that may be good enough , for myself I prefer to at least  close to a flat 30 hz .

a concert grand piano lowest note is 28hz which is actually to the point it’s fundamentals bosrder on vibration that’s why 30 hz is a very respectable goal  , and the larger the driver the more air volume it can push 

And the larger the driver....the Slower it is.  The bass setup on the x-3's is more than adequate for Music...I'm not interested in Home theatre. The way Borresen has constructed the cabinets...the bass is deep and FAST and Tight. That's the way Live music sounds. Much cleaner and clearer that 12 or 15 in woofers. Borresen's technology is upsetting the speaker industry norms. You have to experience and judge for yourself.....I love the bass on these. But then again, I love TIGHT TUNEFUL Bass...not the bass that big 12 and 15 inch woofers produce.

Here is a nice video which showcases the X2 with a follow up comparing it with the X3.  It's in Korean but with english subtitles.  

I've ordered the X2s which works best for my limited space in my dedicated listening room.

The thing you must keep in mind with the Borresen woofers is their radiating surface area is a true 4.5” inches, only about 1.75” smaller diameter than the surface area of most brands’ “8 inch” cones. As such, these “4.5” drivers look more like a typical 6” driver in person. The X3 has a good bit more bass cone surface area than an industry-standard 8” woofer, and the X2 has approximately the same amount as an 8” woofer. Gotta love math, lol! 

They are great speakers.  They will perform well on the condition that they work in your room.  Borreson designs great speakers but is a bit of a purist and they have minimums that need to be met for the image to come to life.  This was always the case with Raidho too. 

Depending on the speaker, you will need min 9' between (as they go up in size width is greater) and you need typically 3' to 5' behind the speakers.  If you don't have this, my experience is the speakers can be a bit underwhelming.  

If you have a room that is open and you can get them out and give them some space, they will be extraordinary
