I did want to believe the Sound King speaker wire wasn't muddying my mids and treble. I couldn't believe it. Good quality 12 Ga. Swapped back in my Carol Command. To me a fair amount of difference. Enough that I have sought out most of that type of wire I could find and bought it from Summit Source. Stuff like this: http://www.summitsource.com/carol-studio-grade-speaker-cable-silver-plate-pure-copper-digital-wall-high-performance-wire-audio-signal-hook-extension-listed-part-c15615592-p-8058.html Very pleased with it other than you can't get anything as good near five times that price anymore.

If you actually have 2.5 ohms for just the woofer, something is wrong with it. Now if you still have all the stuff for the network hooked up to the woofer when testing it, then possible though still sounds quite low. Should be higher especially if the choke is in line with the woofer.

Or just bring the receiver into the room with the other khorns. You can rule out the receiver at least. Bring your wires. Hopefully it is a quick hook up.

But no bass. Paralleled, you can't guaranty the frequency response due to the different loads. Additionally that is a heavy load on that receiver isn't helping. Start with just the khorns hooked up and diagnose it that way. If you have solid corners and can sit about 12 feet away from both of them, if there is nothing wrong with the wiring and drivers, you should have reasonable bass. You will not have extreme bass as many think bass is supposed to be. The mid and treble will over power the bass if you are too close and the speakers are too close together. About 25 feet away, you will get the thump. BTW, how large did you say your room is?

If those are capacitors under the resistors, it could be a zobel network to allow the filter to work more correctly and have the proper cut off frequency. That is the key to the zobel, allow you to use more of a text book filter arrangement not bothered by the rise in the impedance as frequency goes up.

Have you removed the Heresy's to figure out if the just the k-horns work correctly without them? Also, if you only run the bass on the k-horns, is there any reasonable output? The only times I thought k-horns didn't have bass (hooked up to solid state) was when they were hooked wrong or the room was too small since you have to have some room between you and the speakers to let them develop bass. I've had four or five pairs in different rooms and different amplification to know. I've also had them hooked up to my 5150 without issue though not a great match. BTW, how long have you had the k-horns and were they ever right?

Why both connected and in parallel? Off hand it doesn't sound like a good thing to do or do you mean using A + B?

You are right, the 1522 does 4k pass thru. Even makes a better reason for investing the money in speakers

If I were you, unless you were chasing 4K video then I would forgo the SC-75 or Onkyo and stay with the SC-1522. As far as going to the SC-75, it won't buy you much unless you really need the features of the newer receiver. Pioneer SC to SC, very very similar (same) technology and the SC-1522 will work very well. Just an option so you can put more money where it will count, into the speakers.

A big key with the bass is that Klipsch speakers strive for efficiency and now looks with slender cabinets. With a typical woofer arrangement in a narrow cabinet will require baffle step compensation built in to the crossover. This would lower the efficiency by dropping the the upper end of the curve so the bass can keep up because of the narrower cabinet. Some speakers use something like a 2.5 way arrangement that will roll off the second woofer to make up for their not being enough bass launch support from a wider cabinet. Only problem that typically happens with the second woofer is that you are required to have very good current delivery due to the impedance drop of the two woofers. Since a lot of systems don't have that type of current available, we sacrifice with EQ which eats our power reserves anyway. Some of this goes away with a speaker like the Cornwall but if you want a speaker that doesn't dominate the room, EQ or modify the crossover yourself for the desired curve.

The Denon is rated at 125 watts per channel. For 2 Channel mode that should be plenty for the RFs. I'm not sure you would gain any quality with the qsc amplifier. You would probably loose sound quality trying to plug in a different amp unless it was of very high quality and at least 200 good watts. Save the money toward something better and figure out why your Denon isn't appropriate with the RFs. I doubt just a new amp (in particular that one) is really going to solve the problem (this from someone who is always looking for a silver bullet). 125 watts when run in stereo should be more than adequate for quite loud. 250 watts will get you just a little louder. Even in the review of the AVR-4802 they stated the difference between the older Denon at 170 watts and the 4802 for 125 watts was insignificant (power to loudness wise). Secondly, considering the vintage of the receiver, you probably want to start the front end (DAC, connections, and conversion) and get something like a Pioneer SC series that is rated for solid power and 4 ohm loads with a speaker that dips as low in the impedance as an RF-83 likely does.

It stinks getting old though at least the hearing has lasted this long. Usually using Klipsch speakers that can play clean and loud, the ears start to go first.

I thought it was interesting that the last review I saw on B&W speakers show some major issues in the response including peakiness in the mid upper treble. All the article stated was that B&W must know what they are doing. KLF's aren't exactly smooth and depending on the room, can get quite ugly. I'm not sure they are any worse than the much more expensive B&W's. For my money I would choose the Klipsch unless I wanted the false sense of air and detail due to the B&W peakiness.

The key for this stuff and others like it staying put is to seal and prime the MDF. If not will will likely start to peal away in a few years, depending on moisture and temp changes. If you don't intend on having what you are finishing out for more than that amount of time then don't worry about the sealing and priming. Black sandable primer after sealing is best.

One thing that also can help is using a thin, say 1/4 inch thick foam on one or two sides of the horn. This can significantly reduce the horn brashness and possible colorations. This might be worth a try before trying to do crossover work though knowing what Dean has attacked on other crossover ventures, the crossover update may be your final answer. Room treatments will actually make significant differences also but if you have significant other acceptance factors, they may not be appropriate.

Schu, If you like it, go for it. It may offer you good piece of mind also. I know when I plugged my REF1000s into a conditioner, it did seem to limit the bass punch. Even though the Bel Canto's are IcePower, mine will dim the lights for an instant when I turn them on, and I have pretty good / clean power.

Theoman, Are you talking actual sale price or what people are asking? Many folks may believe that 70's version are worth more than an 80's because it's "vintage". Also the older ones had alnico magnets that some people seek (I'm not sure why with many drivers) I have had multiple pairs of K-horns and have paid less for the 70's than 80's. The 80's versions usually have much nicer finish on the cabinet that will drive up the price.

The good part is it looks like a standard E2 crossover, cut a slot and go get a set of tweeters to hook up internally. I can't remember if the E2 used the K-77 or not though. Definitely no scam though. 250 also isn't terrible for what you got.

Be careful with what you want to accomplish. You will get more extension though it will come at the cost of some efficiency higher up in the low bass. That trade off may be acceptable based on the positioning of your speakers.

Are you talking with no music playing? If so, it is your front end equipment and not the speakers. They are much more efficient than the KG5.5s
