RTi10 Too brite

hydrostream

How could i tone them down a little? I listen to mostly rock and
metal so i like good amout of highs but man way too brite.
I think my 8s were better overall they sure cranked up better.

Try adding a resistor in line with the positive terminal of the tweeters. 1.25R has been suggested before.

If the highs are too bright but not too loud then you can fine tune the crossover point for the tweeter with a in-line 1.0 uf/mfd 250 v mylar cap. If the 1.0 dulls the tweeter too much, try a 2.2 uf/mfd 250 v mylar cap.

If i go to radio shack is that what i ask for? And just add it between
the + of tweeter and wire?
Also after having a look inside of these puppies i would have
thought that it was 2 seperate boxxes instead of being all open
inside. I mean seperate the mid from the woofers?

Yes, just take the tweeters out and add the resistor between the wire and the positive terminal. It is not recommended to take heed to post #2.

Might sound dumb, but have you tried adjusting the Treble control on the receiver? That might help in the short term.

The problem with resistors is that you reduce the soundstage and the brightness but the brightness is still there but at a reduced volume.

If you use caps, you are attacking the brightness head on by preventing (blocking) the harsh mids from ever getting to the tweeter.

Try both and see what works best for you.

I had the same problem of Rti10's being too bright. I ended up upgrading everything and started with a warm sounding amp, then added a tube pre, then got a dedicated cdp. Each upgrade helped tone down the highs. Different speaker cables can help too.

Some free tweaks you could do that could help a little is adding some carpets/rugs (if you have wood floors), adding a bookcase can help absorb along with hanging tapestries, drapes, etc. You could also play with speaker placement and lastly you could try adjusting the amount of toe-in.

All these things helped. In the end it wasn't enough for me and I ended up upgrading the speakers because they are naturally on the bright end of the spectrum.

I think i may sell the 10s and look for something that will fit my
style of music. I just hooked up my sons old AR 318ps and they
are cranked up and sound pretty sweet.
Anyone in the market for a set of 10s missing the feet and a few
nicks here and there?

What I found out is if you blow the tweeter in one of them, the high end milds down quite a bit!

I haven't tried frying the other one yet, but I feel safe to venture the theory that doing so would further reduce the harshness.

Boy jerry giving up on the 10's so fast. I remember when we got these back earlier in the year. Stick with them...don't give up....try the tweek and turn them down...lol...

I love my 10's just wish I had the right equipment to listen to real stereo.

Basically the tweak attenuates the tweeter itself making it not so bright. No harm will be done and you can experiment a little to find out what suits your individual tastes. A 1ohm resistor could be used as well, for example. That's a $2-3.00 tweak that might just make you keep the speakers. Just a thought.........

They are nice speakers.

Turn the treble down -2 dB.

What's the exact part at radio shack?

I would not use any rat shack parts for this. They don't have anything of proper wattage to handle it. The part listed above could be placed in between the two positive binding post instead of the jumper. This would attenuate the highs a bit.

good luck,,let us know your results.:)

Ben how many do I need for this? There should only be 1 positive going into the tweeter correct? So I guess I need 2 right?

Also do you think they have these at our local Fry's?

Seeing how were both in Atlanta I may use you in about a year when I complete my basement home theater build. Do you know a thing or two about projectors?

are you driving them with the onkyo805 + audyssey calibration?

You ****! You didn't show up for the PFGA I know setup of projectors. Others here can give better advice on a purchase. I was an electricians so some wiring can be done. Now back to the resistor. It has to be ordered. You would need one for each speaker. Like I said install between the speaker jumpers, and don't bother opening the speaker. If you install the resistor at the driver it will throw off the XO point.
Ben

joe.inom

you can tune your equilizer such tha the high values of K's are turned low , such teh the tweeters sound will be reduced.

When was the PFGA??? Where...I'll show up next time. So your saying where the brass jumper are...that would put it outside the speaker at the terminals right?

yep. Thats it. You are welcome any time. No need for a big group. I like to meet Polkies.

I am going to give this a try on my RTi 8's but I would like a little background considering I do not know circuitry.

1. (2) binding posts; does this mean that there is an independent highpass crossover for the tweet and a low pass for the woofers. (This seams logical)

2. Do the resisteres lower the volume on the tweeter? I am thinking that by increasing the resistance I am lowering the amps and volts. So, if the tweeter is too quiet with the 1.5 Ohm I could try the 0.5 Ohm. Is this correct?

Let me tell you about my other problem with the 10s.
The one mid woofer had a problem the spider came seperated
from the cone. Had that repaired but if i add any kind of bass
and start to crank it up the mids go crazy to were you get that
thud or crack sound. I had picked these up used so okay i will
replace the mids. Ordered new ones from polk ($48.00 each)
and still the same thing. I could beat on my R50s more before
they carry on. So if i use the resistor and connect it at the
binding post that will afect the mid also?
Help jerry

Some thing bad is seriously wrong with your RTI10's from damage somewhere.. might not be working sinking more money into them.

Help jerry

Have you tried talking with Polk customer service? They are the best in any business. Adding a resistor as you have talked about is probabley not a good idea and you may be better off doing a well planned mod to the x-overs. Other than the folks here the guys at Sonic Craft who manufacture Caps are real helpful too. Phone 501-620-4444 or soniccraft.com
Just trying to help ya out

hydrostream

As far as polk C/S no help they said maybe i'm over powering them
well went through that tried all my amps and even my onkyo 805.
C/S said they may have been dropped. I know they should take
more then i'm giving them. I have to turn the bass way down or
i get that thud sound. With my RTi8s i was able to get more bass
out of them. I just can't give up on this its starting to piss me off.
One thing i'm happy about is my $30.00 wharfedales kick **** and
so should these 10s.
jerry

danger boy

your speakers are jacked from some kind of damage... sorry I can't be of more help... but something ain't right with them towers.
