I have consumed heard in a magazine mounted on a yamaha amplifier Yamaha P5000S 2 x 500 compared to 115 + JRX Audiophony CX850 amp 2 * 260 and sorry but these two coupled sub (hort wharfedale parts and only 300 euros) is a config more balanced in the treble and mid and most 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)
is a more accurate system more powerful and scalable for 1900 euros (if JRX 116 in sub) and mounted with 1500euros wharfedale (and can dabord bought the satellite and the subs)

otherwise, it is better to wear than a 2 times 20kil 40 times
