JBL 4520 vs 4560 for hifi use?

[retro soulman]

hello!!! i got a real dillema and i wish that u can help me!... i got a pair of 4520 with k140 and E130 drivers. 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!:dont-know:

I think K140 and 4520 should mate good together. I would go that way and put some horn on the top. Nick has some ideas about the 4520 http://www.audioheritage.org/vbulletin/showthread.php?34134-DIY-4520-bass-horn-build

I believe that the better choice is to get 4 2225 for you 4520. Then you can use your e130 in mid horns, but not the 4560 they are too short.

Both the k140 and the 2225 are drivers listed for use in the 4520.

4560 doesn't go very low I think. Wouldn't be very useful by themself. I bet they would work well on top of the 4520 :D.

Hello retro soulman, I have here and used both the 4560's and 4520's. In a home although their are big the 4520's are your best choice. The 4560's being a front loaded short horn has about a 6db boost from 200hz and up. Does not go as low as the 4520's either. Horns that were used on my 4520's were the 2'' versions 2397's 2360's and 2309/2310
