I have consumed heard in a shop (JRX 115 + 2 * amp Audiophony CX850 and compared with JRX 125 mounted on a yamaha amplifier Yamaha P5000S 2 x 500 and 115 small good news behave better and coupled to two sub (and yet wharfedale Parts only 300 euros) they are a more balanced config in the high and medium and more powerful in the lower (warmer sound)

wharfedale the box has a 38 cm and provided for 300w rms
imagine with JRX 118S boxes with them to a 46 cm and fed for 350 w rms (500eu)

conclusion is a system while an about 1500euros bof (cash) the JRX 125
is a more accurate system more powerful and scalable 1900euros (if box JRX 116) or 1500 is a wharfedale VU ALL!
otherwise, it is better to wear than a 2 times 20kil 40 times
