I have the oportunity to buy 4 2225 drivers (broken lead wires) plus 2 2421 (one driver got 8 ohm diaphragm and the other 16) with jbl lenses. with the same money i can buy a pair of jbl 4560 with drivers (i have no idea if the drivers are jbl or in what condition they are). And im asking u! what do u believe is better!? to make my 4520 like original or to buy the 4560 and put in them my k140 drivers?? which of these 2 type cabinets are better for hifi usage??? thanks!
