I have Reference series for my front stage. I have the opportunity to grab some KLF-30's that I would use for my surrounds. I'm wondering if anyone has done anything similar to this setup. It makes me sad to waste all that power in the 30's using them as surrounds. I'm almost half tempted to throw the Reference in the back and use Legend series in the front.
Obviously some testing and personal preference would help - but wanted to get other folks' take on this setup.
Thanks ...

Ahh who cares - it's the name of the game right? If technology didn't change then we'd never have an excuse to upgrade. [

K for all you naysayers and haters out there - I got my XLR/RCA cables and hooked them up from the Rotel to the Denon. Made the adjustment on the back of the Rotel and switched to 'balanced'. I turn the power on and ....... a distinguishable difference in humm noise. Actually it wiped out all of about 90-95% of the humm. I think the rest of the humm will go away with a better power cord and maybe plugged into a shielded control strip.
Anyway - XLR cables made a huge difference for me. I'm loving the Rotel Klipsch combo. What a sweet amp!

bc, did you understand my answer to your PM? That might clarify the situation.

Michael,
was hoping you'd pipe in here soon. For some reason your PM did not
come through for me. I show it has been viewed but no reply. I'm
interested to hear what you think though.

The Denon only has RCA
outs. Using a cable that has RCA at one end and XLR at
the other is NOT a balanced connection, so you will NOT get
the interference-blocking benefit that a balanced connection
can give you.
Also, according to your initial description,
you describe a passive bi-amplifiation situation where you use the
Rotel to power your LF section but you still use your Denon's
2 front channel amps to power your HF section.
Correct? Was this your intention?
Yes originally it was my intention to bi-amp the speakers with the
Denon and Rotel. After further experimentation I went to only wiring
the Rotel to the speakers. I think I'm getting better performance that
way. I'm very, very, very impressed with how hard the 1080 pushes the
RF-7's. I've never seen the cerametallic cones move like that!!
-
I can understand what you mean and it does make sense. I guess my evolving question now is, how do I get rid of the hum then?
-
Klipsch speakers in general are SO dang efficient. You will have great
listening pleasure with your 1605, or whatever it is. If you went to
the Denon 3806 it would make the RF-7's sound extra good. If you went
Denon 5805 you would crap your pants. And if you went separates with a
Rotel or Carver amp you would probably self-combust with so much
listening pleasure.

ARGH!!!!
People, REAL XLR connections place the entire sine wave of
the signal on the positive side of the speaker cable. A
transformer is required to then remove the signal from the + side of
the cable and feed it to the speaker. The reason for this is to avoid
induced signals into LONG runs of cable (say 500 + feet like in baseball stadiums!!!!)
XLR jacks on CONSUMER grade gear are only wired the same as RCA cables,
on consumer grade equipment, NEITHER IS BALLANCED!!!!!!
OK - then explain to me why Rotel places a 'balanced' and 'unbalanced'
label on the back of their amp for XLR and RCA wiring, respectively?
Can you also explain why my uncle who is running a Parasound Halo amp
with his Yamaha used XLR cables and it took the hum right out of his
system? RCA = humm, XLR = quiet.
Am I restating what you just said? Sorry I'm really trying to figure this problem out.
Thanks ...

Carver, Macintosh, Rotel, Adcom, OutlawAudio, Parasound ... Maybe flip a coin?

Welcome to the board.
You should definitely be able to haggle that price down from $1800. I
picked up my black pair for $1500 straight up from Ultimate
Electronics, and I think they're the worst store ever.
Hope you can haggle a better price. Don't let 'em bully you!
-
I would say the best way to wire the Rotel and Denon are NOT
to bi wire. The rotel is a much better amp than the denon and you
will only lose sound quality. Let me know how you like the the XLR cables I was thinking of getting some my self to try.
What you're saying definitely makes sense. I will try a straight feed
from the Rotel into the RF-7's tonight and do some experimenting.
Thanks ...

The 3802 does not have XLR outs. You can't
run XLR. An RCA to XLR converter cable is not balanced and will
not make a difference.
In your previous statement you said that NEITHER had XLR. I understand
that the connection will be an XLR to RCA because of the Denon, but
from everything I've read on Sound and Vision forum the XLR is a noise
reducing coil and will take that buzz out. Hard to know til you really
try though right? I'll let you all know if it solves the problem when
they arrive.
My uncle has a Parasound amp that is pre-amped with his Yamaha and the XLR cable reduced the humm completely.
Out of curiosity JZOZ, if the XLR and the RCA are the same thing (so to
speak) what would you recommend to take the humm out of the speakers?
-
Denon is highly recommended with Klipsch. I have a 3802 and it pushes
my Reference series setup very well. My brother also has a Denon, the
3803 and he pushes the Legend series KLF-30's with his.
Denon also makes a great pre-amp as well. I recently purchased the
Rotel 1080 2-channel amp to add some 'umph' to my 7's. And boy did it.
You won't go wrong with a Denon purchase. The 3805 has gone down a tad
in price since the release of the 3806. Maybe consider out of those 2
models: http://usa.denon.com/ProductDetails/11.asp
Let us all know what you decide on ...

Disconnect the old speaker wire, receiver to speaker. Put jumpers back on (if you removed them).
Keith
T2K - I was under the impression that bi-wiring with the jumpers was a no-no. Do you know different?
-
I have some XLR cables on
the way and am hoping that will resolve the issue there....
And what are you planning of doing with those? Neither the amp nor reciever use that connection.
Because I own the 1080 and have actually seen the XLR connectors in the
back of the machine I know for certain that it has them. The XLR inputs
are for a balanced signal while using the RCA's is an unbalanced signal
(hence the humm).
Here is the back panel drawing for your consideration: http://www.rotel.com/support/pdfs/drawings/RB1080-back.pdf
I'm quite certain the coax cable is not creating a hum. More
importantly than the humm, for now, is my question to the appropriate
way to wire this 1080 with the Denon. Is Bi-wiring really the way to
go? Or should I simply connect the Rotel only to the speakers?
Thanks guys ...

Running RF-7's in the front and a RC-7 center. Just want to know what
the optimal way to wire the Rotel to the Denon would be to get the most
satisfying results. Right now I have a huge hummm/buzzz coming from the
speakers because of the Rotel. I have some XLR cables on the way and am
hoping that will resolve the issue there.
Current wiring is I'm running straight RCA's out of the Denon front
L&R preouts to the Rotel 1080 (hence the buzz). I have the old
speaker wiring from the Denon going to the opposite prongs in the back
of the RF-7's than before when I only had the Denon wired. The Rotel
speaker wiring is going to the other set of prongs on the RF-7's.
It sounds great - except for the buzz. I can REALLY tell a huge
difference with the Rotel amp - that think is beautiful and has
awakened my 7's to a whole new sound stage. They really sound like new
speakers.
I just want to make sure I'm wired right for both 2-channel stereo/music and also 6.1 movie surround.
Anyone have this current or similar setup? Thanks guys ...

WHOA! Amazing setup Nich. Freakin' hell I can't imagine the power your home sucks up! Next time lets have some better pics huh? Sheesh. A setup like that a mans' gotta have some camera skillz right?
Seriously sweet theater ...

Great prices you lucky dog~!

Excellent feedback CECAA850,
I haven't fully written off the RS-7's yet.
-
Doesn't seem to far out there. Ultimate Electronics was an Authorized dealer and they shot me about $750 each for mine ...
-
Wow that is a great solution to go with the RB-75's. It's so obvious that I didn't even consider. Definitely something to look into.
I know this same question has been posed numerous times throughout the years here, but thought I'd ask a more recent version and see what people said.
I'd still be curious to know what other RF owners are doing and if there is any real substance to the rumor of the RS-7's sounding like crap for surrounds. And by crap I mean a general and very vague statement for I don't know what ...
-
I don't have the hottest surround speakers. They do alright as far as volume and presence and all that, but they don't really match the front stage. What do some of you guys do for your surrounds that are running RF's in the front?
Another pair of RF-7's to me sounds like a huge overkill for surrounds. Perhaps 3 more RC-7's? (rear center) I've heard the RS-7's are not that great, but most likely better than what I currently have. So those of you who have first-hand experience with this, let me know what kind of solutions you've come up with in your own setups.
Thanks ...

Got my RF-7 fronts for $1499.99 for the pair.
Got my RC-7 for $599.99.
Got my RSW-15 for $1199.99.
All from Ultimate Electronics. Then they went out of business.

Perhaps look into Outlaw Audio or Rotel. May save you some moolah. I'm looking into separates. Probably leaning towards Rotel although last I checked they don't have a 7-channel yet. Outlaw has great deals.

KLF-30's For Surrounds?
in Home Theater

Thanks for the feedback. I think I'm going to go ahead and do it. I can get a pair of mahogany 30's for $800. In my opinion there is not a better series of speaker made for 2-channel listening. The Legend series is so musical to me.
Can't wait to hear them with the rest of the setup ...
