RC-7, RF-7 and RF-82 crossover schematic?

[Andrea C.]

Hello everyone,

this is my first post but I've been lurking for a while, now.

I'd like to upgrade capacitors and inductors in my Klipsch speakers, specifically the RC-7, RF-7s and RF-82s. A friend of mine who's into DIY offered to help me and opened my speakers to check their inside. He said he needs to know the value in microfarad for both capacitors and inductors, though, which should be specified in the speakers' crossover schematic. Unfortunately, it's not written anywhere on the physical part.

Could any of you DIYers help me retrieve the information he needs?

Thanks in advance!

Welcome the the forums!

Two seconds of using the Search function yielded this:

for the RF-7s. I'll let you spend the other 4 seconds searching for the other speakers you need. []

Welcome Andrea,

The caps have the values in MFD on them along with the voltage rating. If you are just replacing your caps then you won't need a schematic for the value of the inductors. I have DeanG crossovers in my RF-7's and modified my RC-7 and I am very happy with them. If the RC-7/RF-7's seem a little bit on the bright side, I would recommend the resisitor mod that DeanG uses. The mod makes the RC-7/RF-7 sound more like the RC64/RF-83's.

Hi wuzzzer,

thanks for the link! Unfortuntely, RC-7 and RF-82's schematics don't seem as popular, and I can't find them either over here or through a google search Do you think caps and inductors on the RC-7 could realistically be the same as those on the RF-7s?

Hi Southern,

thanks for your reply. I'm replacing both caps and inductors, so I need both values. I know caps have their value written on them ('cause my friend told me) but it's impossible to read without unsoldering them, and I have no soldering iron. I'd have to ask my friend to come to my place with his soldering iron, unsolder my caps just to read the value and put them back in place. I was hoping I could save him this work until I was ready to actually replace them

Since I just replaced the Caps & resistors on my RC-7 I don't have the inductor values but here are the capacitor& resisitor values:

Low Frequency Section:

Resisitors: 1.5 & 2.0 Ohm

Capacitors: 24 uF & 28 uF

High Frequency Section:

Resisitors: (2) 2.0 Ohm

Capacitors: 3.75 uF, 12 uF, & 18 uF.

Resistors are 10W, Capacitors are 100V.

Here is a write-up I did modifiying my RC-7 with pictures.

Hi Southern,

thank you a lot for the link and information!

I reckon no RF-82 owners have modded theirs, yet?

The RF-7 mod grew from the desire to tame the harshness on the upper end. The newer Reference speakers aren't perceived as harsh as the speakers they replaced so not many people have modded theirs yet. At least that's my thought.

I think alot may depend on what gear you run but I do not get harsh with the RF-7. I heard them and loved the sound from

the very start, and they sounded even better when I got them home on my gear. No mods needed here!! They sound great.

I won't be touching mine!!

IVe searched the forum here and I can find nothing on the RF82 II CAPS. Are they 50v or 100v?

100v

I realize this is a 5 year-old thread, but the other link referenced was broken, and others might come to this thread looking for this info.
