Hey Guys,
I want to use 'Channel B' on my receiver to drive 'only' the tweeters only in my 2-way Klipsch speakers. If I unplug the crossover jumpers going to the woofers so only the tweeters are connected to the crossovers - can I cause any damage anything playing them this way? Do I need to have a load present where the woofer normally gets connected in the crossover? My receiver is an older Pioneer SX-1000TW.
The speakers (klipsch SB-2) themselves are rated at 8 Ohms - I get 5.9 DC resistance when I measure the tweeter, but I do not know the specific Ohm value of it. The other set of speakers connected to 'channel A' are 8 ohms as well - if it matters.
Any insight would be appreciated!

It's like you are asking if you can allow two people in the backseat of your car .
If it was projected and provided for that duty , the are no reserves .
Some more in depth of electronics analysis would bring also some observations
and ideas , such using passive filters at line level to somehow limit amplifiers ' BW .

PWS,
Thanks for the response man but I'm not totally following you on allowing two people in the backseat relation..sorry for my ignorance. It's a klipsch bookshelf speaker and I'm disconnecting the woofer from the crossover to allow the tweeter to play without the woofer. What 'values and analysis' would one need to find out if it is alright to hook up the speakers to a receiver this way without doing damage? I'm not trying to figure out the frequency tuning or anything like that yet. Just trying to figure out if this will create an unusual load on my receiver or create too much oscillation to the tweeter and do damage.
I know I can purchase a high pass filter from parts express, but since I have a 2 way crossover already designed for the tweeter I was hoping to just use that.
Any help appreciated.

Well...Hi!
You would do just the so-called 'bi-wiring' , which is to bring from the amplifier two couples of cables instead of one ; selecting A, B, A+B you would make working the woofer or tweeters alternatively or all together .
One good thing would be to take out of the cabinet the crossover and put it in the vicinity of the amplifier . 🙂
( this makes sense only for the woofer path , since it changes very little some damping factors due to the resistance of the cable before the inductance -lopass )

PWS,
Oh I see what you're thinking! Okay, maybe I wasn't clear about my intentions.
The first set of speakers on 'A' will just be a set of 3-way(full range) un-modified speakers - nothing will be change on these speakers. They will be connected on 'A'. On channel 'B' I have another set of speakers connected, but I want to remove the woofer so only the tweeters play. I'm not trying to bi-amplify one set of speakers, rather just removing the woofer from the speakers on channel 'B'.
My only question is, since I am taking the woofer out of the crossover, do I need to install a resistor in place of where the woofer used to be on the cross over to keep it stable, and cause an unusual load on the receiver or tweeters.

Ah , ok
....Why 😕
Some would say to take precautions if the tweeter path was left unloaded -without the tweeter ; but , for bass there are no problems .
If you've got a double binding posts for tweeter & woofer separate , it would be better ; indeed , well ...try 😛

Hi Pico -
Thanks for confirming. The reason for doing this is because I have some Bose 901's that I am trying to improve. Bose 901's have nice bass IMO, decent midrange, but lack delicate high's. I particualrly notice it when in comparison to my Polk SDA's...
So, since I have an extra channel 'B' I was going to remove the horn tweeters and crossovers from some damaged Klipsch speakers and prop them on top of the 901's - and power them separately on 'B'. Now, I know that this is going to come with mixed results because I also have to contend with the 901 EQ, but I thought it was worth experimenting before I completely give up. I thought it would be cool to be able to have the option to add some high frequency's by pushing the 'A+B' button on my receiver for when I want to hear fine detail.

Yes , you might give it a try ...🙄
I haven't listened to the famous 901 , and there are some people in favor and some against that design ( direct / reflecting ).
Those are muddy waters 'cos the sound will depend mostly on the room , and its acoustics . So if you have absorbing surfaces behind the speakers , the highs wouldn't be reflected at all . And if you put the tweeter directed frontward it would be under the EQ effect .
If you specify what kind of Klipsch model you have , maybe somebody could chime in 😀 and tell a possible replacement for the woofer .
Making your own cabinet could be sooo sweet

I thought everyone loved Bose? Ha ha....Just kidding : )
Seriously, I actually do like the 901's. I've had them for about a year. I have perfect walls for to reflect off of and a big open space. They fill my entire house with music. They're non fatiguing and fun speakers if you are not being critical about accuracy and distortion. I also own a lot of high-end speakers that are much much more accurate. One of the negatives of the 901's is that the highs are comprimised becuase of the drivers used; they're all mid range drivers. So the tweeter is going to face the listener on top of the cabinet and should be able to pick up some detail I'm hoping. If I reflected it, it would lose detail IMO. The biggest leap is getting the EQ to blend in nicely. I might get an L-Pad to adjust the volume of the tweeter. I will post up pictures once I'm done, maybe even take some video of with and without the tweeter to compare the sound. Should be interesting. Thanks for your help!

Hi !
My concern were eventually on the final sound you'd get .
I guess ( at this point ? 🙂😀 ) that it's all most reverbered sound you'll get ,some kind of ambient . So the inaccuracy you alluded to , it is a matter of phase coherence , which is not the problem you have to face if you like the sound of the 901s . Take a look at omnidirectional , expressively at
ww.visaton.de/en/bauvorschlaege/rundstrahler/index.html
maybe a little tweeter placed on top with a little cone on top ...

That is actually a fantastic idea! Having an omni-directional tweeter would give me some reflecting and some direct facing highs, which matches the 901 concept. I like it.
Those speakers remind me Ohm Walsh speakers... very similar ideas I think. I guess I will have to experiment now! It shouldn't be too hard to build something similar to the cone idea using some sheet aluminum. Thanks for your input!

If you have a voltmeter that reads alternating voltage you can get a reading on the woofer's connectors with music playing. If there is voltage you need to put in a dummy resistor or disconnect the large inductor on the circuit board. Radioshack has a two pack of 10 watt resistors for $3.
Just make sure that the high pass filter remains in-tact when wiring up this way. I see no reason that it should not but it is crucial that you don't accidentally wire up the horn without a high pass in place to protect it from low frequency energy.
Thanks guys.I went ahead and hooked up the horn tweeter with the crossover to test it out. Results?? 100% improvement! The tweeter completely transforms the 901's into highly detailed sounding speakers! On jazz music I can now hear the fingers sliding up and down the strings. I can hear fine detail that the stock 901's could just not pick up. No more dull sound anymore. The mids actually blend in nicely in this setup. I might try a lower UF cap to see if I can improve it, but for now its fine.
I ended up turning the tweeter backwards facing the wall and it seemed to blend in even better reflecting off the wall. I think the sound could be even more improved with an L-Pad to lower the volume on the tweeter just a tiny bit.
If Bose built these with a tweeter and matched the curve they would have a better speaker IMO. I'm not sure if the 901's are going to replace my huge Polk RTL 15's but they are making me question it now....😀 Thanks for all the tips and help on this, guys.
