The hissing is not coming from or caused by the speakers. It is created by your amp. The efficiency of the Klipsch speakers displays the weakness in your amplifier. There may be nothing to be done but to replace the amp with a better one.

I have quite a bit of trouble shooting. I don't have enough TIME!!!
Sorry, I couldn't resist. Clu should get it.

Clu/Less,
Fainting is sometimes serious. Are you O.K.?

The front face is smaller, but they are deeper. The ports are above the woofer, making the cabinet shorter. They *might* be sized correctly.

You can send it to klipsch for repair. Call 1-800-KLIPSCH and ask for Trey or Matt.
You could also replace the cap in kind if you can use a soldering iron moderately well. Start looking at a commercial electronics house, not Rat Shack.

Why would you want to replace one paper and foil in oil capacitor with another one? If for no other reason, the Jensens are a mystery to me.

As best as I can remember, #3 is in the Klipsch Museum.

The Karlson Koupler was at least partially responsible for Mr. Paul's "Bullshit" button. The Klipsch Museum had one.

I'd buy a KSW-15. You'll want a high output sub to keep pace with the Heresies.
I place the squawker at eye-level when seated.
I bought my rear La Scalas off of ebay, but audiogon.com and audioreview.com have classifieds with several Klipsch listings.

I have not heard an RC-7, but I'm satisfied with my KLF-C7 as center between La Scalas. A Belle with early AlNiCo drivers would be a great center for you. AlNiCo is naturally shielded. You may have to search for an AlNiCo woofer, but they're out there. This is likely to be a project. You'll likely find a speaker with some AlNiCo drivers and have to substitute the rest. Naturally, this could be done with a Heresy, La Scala or Cornwall, too.

Hello Miss Bec... er Mystery Guest,
It sounds like you have gotten settled in. How are you liking Indy? I'm sure Steve has plenty to do, but tell him to come by and visit more often.

ALKs are not available for Fortes. The use of superior components and careful matching of the filters for each driver, plus an impedance matching trick makes the ALK networks sound so good.

One member did just what you asked about, contoured the openings. I front mounted my tweeters and found it reduced harshness and improved stereo imagining. Contouring the squawker opening and continuing the flare, would require cutting the cabinet too much for the screws to hold, so I lined the squawker opening with heavy felt from Home Depot.
Klipsch makes "Z" brackets that mate flush mounting the tweeters a lot easier. Call Trey at 1-800-KLIPSCH.
Damping the horns with rope caulk or Dynamat has been a popular undertaking. It works!

Midnight security guard at a river barge manufacturing plant. No gun, just a phone and a watchman's clock. I was 22 and would have wet my pants if someone broke into the place.

Hi Bev!
You shouldn't have been gone for so long!
Still workin' in the same old salt mine in the City of The King?

I'll take a guess. Fabric wall coverings the deaden the room? Persian rugs on the wall?

The kit you are looking at is not the same as the Wave. It uses different tubes. Without seeing the schematic, I can't say if it is similar.
I;ll sell you a pair of Waves, with covers, cords and a spare set of "matched" tubes for $200. They have about 10 hours on them.

I say subwoofers (2) and center, first. Surrounds could be a $20 RatShack speaker for a while, if they become important.
Since Belles are so powerful and low distortion, you'll need 2 powerful subs to have a chance of keeping pace and having low enough distortion to blend in. SVS can be bought online and is said to have subwoofers that can fill the bill. I use a pair of VMPS subs and a 400 wpc amp with my La Scalas. When in the corners the VMPS can match loudness up to my personal limits, even on Stone Temple Pilots.
I use a KLF-C7 as my center. It is not a perfect match, but is close and sounds great. It can match the La Scalas to the levels I can tolerate, as well.

Since you're increasing the impedance of the speakers by 33%, you decreasing the amp's outpot by 33%, or down to 97.5 watts. What speakers will you be using? It Klipsch, you COULD operate on 1/10th of that power. I'd suggest looking at a 50 to 60 watt Yamaha, Sony, or the like.

You may have to chase the wires to the woofer to confirm what may be out of phase. Check everything carefully. Each of the drivers have a red spot on the + terminal. The Type AA is a fairly simple network with no phasing tricks. + from the input terminals is plus through to each driver, even though the squawker runs through the autoformer.
Here is a copy of the schematic.

Look at pro audio gear like Peavy, Crown, Quest or QSC. Distortion and sound quality don't apply in this application. Buy tough.

I believe you're looking at a trip to Circuit City to see what they have. Speakers make the most impact on sound, so I'd look for a pair of SB-1s for about $200 and go from there.

Nad L40s are cool, but hard to get in your budget.
Used Advent receivers are really nice, too; can't find a pic.

Sulfur Hexaflouride? SF6. It's a strong dielectric and is used in switchgear for high voltage transmission lines. It supresses the arc between contacts when a 500 kV T.L. trips.

I don't think there are any natural instruments with fundamentals above 6k. That means all you'll hear from a tweeter by itself are harmonics. It will sound very strange indeed.

Should we petition for a convention?

I think Summer 2003 would be great. Say, in Indy on the last Sunday in May?
I'm going to take a firm position and vote for the city the Company chooses to invite us to.
I *think* the museum is still in Hope, but I believe it was destined to be moved to Indy. We'll have to see where it will be. One whole roll of my film, most of the stuff in the museum was ruined, so I would like to go back and get more shots. Outside of the Museum, the engineering and R&D labs were the most interesting part of the Hope tour. The whys of producing a speaker and the testing to see how it sounds and what is needed to "voice" it turned out to be most fascinating. That is all in Indy, now. This is about the right time to start talking about a trip, if we're going to do it.
