Hello all of you Jamo owners! And thank you for really interesting readings. A special thank you to those of you who provided schematics of xovers. I was going insane trying to figure out how my xover was coupled. Never heard of this isobaric xover.
Been reading this for a couple of weeks but joined this forum today!
The reason is, I own a pair of Jamo 707a (yes, 'a', that´s what the label on the rear terminal says). I bought them in 1994 and it seems like Jamo kept this curved design for quite a while, as it can also be seen in 707i and D 590 models (maybe more models?) The interior changed, though.
To cut it short, I have never been a hifi diy-guy but I had to refoam the push-pulled 8" woofers, with success! (Mind you, I am 70+). Since the cabinett is very well built, IMHO, it seemed like a terrible waste to just throw them away.
I recently bought a new integrated amp, Rotel RA-1572 MK2, and the speakers sound just great. However, what to do with a 28 years old xover? I think I need some more clarity in the upper regions, or maybe it's just my aging ears. But they are the ones usually listening.
I can see from Jawens (hey, I'm from Sweden too) and Moorclos' posts that my xover should be the same isobaric 4th bandpass, with other values and names.
My capacitors are: C1 10uF, C2 72uF, C3 150 uF, C4 4,7 uF. Attaching images.
Well, stopping here before you get tired of reading. Your help will be highly appreciated!
Thank you and take care!
