Internals of the RF7 lll


STSOE

Recommended Posts

Hey guys. I have been following the forum on and off for a couple of years but this is my first actual post.

I am quite curious if anyone have upgraded the internals of the RF7 lll?

I remember someone on here make crossovers for the original at least. I am thinking about upgrading the wiring, terminals etc.

Any recommendations?

Everything else in my system is pretty decent. I just want to see if i can get anything more out of these amazing speakers.

Right now i am pretty confident that the internals of the speakers is the bottle neck so to speak.

Welcome

 

I know nothing about any of the RF line but will say, many times a change does not mean an upgrade. It may sound different but what was really changed and what else was affected ?

And what makes you think this ?

The III's don't have the shortcomings that the 1's did.  You might listen to them as is for a while and discover that you like them as is.

Shortcomings or not. I ain't gonna replace the whole thing. Just the "lesser" parts. Terminals, wiring etc.

I'm betting you'll spend time and money on the project, and will hear a definite improvement.  And that if you subsequently A/B them against stock versions will only be able to hear a difference if you know which pair is playing.  And that any third party will not hear a difference, blind or sighted.

 

If you change capacitors and/or coils the chances are greater for an actual difference, maybe.  As to whether it'll be an improvement or not, well...

That's the plan. And no i am not 100% sure that it would be an improvement if i just change some stuff to more expensive versions with the same values. I got a mate who upgraded the internals of a pair of rb,'s though and they really sound amazing.

 

Better components is always a good idea no matter what speaker we are talking about.

You are not right about that. I could easily a/b blindfolded if you changed my speaker cables. The same goes for the internal wiring just by a greater extend i suspect.

 

I didn't believe in wires until a mate tried a new pair in my system and holy shit, i upgraded everything shortly after.

Caps are the typical starting point.  The sky is the limit on pricing.  It will be a fair amount of experimentation and cost to find out if you like the "better" version or not.

You are absolutely right. Hence i was hoping for some good advice from you guys. 🙂

This is your chance to be a Klipsch Pioneer!! I don't think anyone has torn into their RF-7 III's yet. I guarantee you that the crossovers and wiring can be upgraded at the very least. And if you crack them open and document the design and values of the crossovers you'll get a lot of help from the experts on this forum. I for one am itching to see RF-7 III guts!

Really? No one has done this yet? They have been around for a while now.

And yes i am pretty sure that the wiring and crossover could use an upgrade. I am just not that sure what would be the best way around this. I could always use the same values but with better components and some good wiring.

Just wanted to see what you guys have done with yours.

I find I like the steeper slopes over the simpler designs like type A or AA even when built using premium parts.  

 

Steeper slopes can make a big difference.

 

Went to a class about a month ago put on by Klipsch's chief engineer, one part of the class was doing listening test with a few different crossover slopes so you could hear the differences. If I remember correctly it was 4 different slopes on the same crossover, the majority of the people there chose one of the two of the steepest slopes after going back and forth a few different times and from different positions in the room.

All of this is why I am mostly not fond of changing things with proven speaker designs, the crossover slope is only a small part of what goes into a design. All of these different changes which are many just with crossovers alone are setup to work as a group, and is proven with testing to get a final design. Seeing some of the many different driver combinations, crossovers and  other things that go into a design and tested through each step and at any time is subject to change for different reasons makes it pretty impossible to have good reliable results from general switching out parts, and calling it an "upgrade".  

 

You may change out a part that cost more or looks to be made better but what have you done to the overall picture and performance,  there are many different things that are taken into consideration and proven by test, if you could see everything considered and tested to see what each change actually does to the overall performance electrically and sonically you would have second thoughts about just randomly swapping out parts.  

 

Don't take this the wrong way, I love DIY and think once you buy a speaker of course it's yours do do what you want, I just wish everyone could see how little changes can change other other things not even considered.  A simple recorded plot testing one aspect only says so much and that result is only sonically, what really changed to get those changes ?

This.

That's why repositories of know-how and experience, like this here forum, are such a valuable resource. Speaker builders make as good a sounding speaker as they can within the confines of the budgets they are given. There is always a compromise. Then we, with the help of these forums and our experiences, can extract the few missing bits of performance out of those designs. But care must be taken to avoid thoughtless "Swap-tronics".

No worry. I get where you are coming from. 

This is one of those 5% scenarios. But hey. I love these speakers. And i would gladly pay to get those 5%. I am driving them with a Hegel H590. So i already overkilled them. 😉

I will be putting up pictures on Saturday.
