The enemy of good is sometimes, well? It is best to keep bass management as simple as possible. Woofers are not subwoofers and poodles are not German Shepherds. I quickly learned that a sub or two can beat most Towers, if done right. To get total coverage of the sound spectrum, $$$$$ for most tower speakers.
It is not the best design for most systems and subs can be a bit cheaper the DYI route.
Using a sub helps keep the speaker drivers under control. PKW said something about speaker drivers being over pushed?

If it is under warranty, make sure to follows Klipsch's instructions. Call if needed. Is there a local Klipsch authorized dealer near?

Need lots more info. How large is the room, speaker setup in room, ?bi-amping(passive vs active). I drove my RF 7 and & II's with a 25 watts tube and and 50 watt SS. I also used 200 watt power amps. The midrange should not be that weak.

New receiver is coming into the pic?

Fascinating, PWK needs a movie of his life story.

Even if possible to hook-up the sub to the soundbar, it does not sound like it will be fruitful.

The subwoofer is more capable of reproducing the lower frequencies and allows for a little more headroom in the a AVR.

Redo the entire setup! The power things unless it is truly and outside power problem, most folks don't need power conditioners except to have a fancy power strip. Looks good but, no Improvement in the real world. To get better sound, new amps, speakers and room Tx's. Anything less is playing in the sand at the park.

The OldChen amps sound nice but, the fixed bias is a problem and necessitates opening the amp with power tube changes to readjust the bias due to possible amp damage.

You have your work cut out. I look forward to the restoration.

Waiting years for an amp, this is really funny since there are so many other options.

New toys and the fun of integrating a great system, enjoy!

Free speech also has it consequences. This is a audio forum and other matters should be on other social media! The forum has places for social talk, recipes, music, pics, etc.

I like the new nearfield projectors that can sit on a conso! Next to the wall and. project 100-120 image crystal c!ear. The near field projector is located up front.
You can use it for regular TV.

Lots of nice gear. Some pic's would help with sale. Good luck.

The question is not which tube to build an amp around, rather the design and execution. 300B, 2A3 and the other mentioned amps types can all be nice. Demo some amps is the best way or make it run multiple tubes.

The Marantz NR 12 may be a consideration: https://www.amazon.com/Marantz-NR1200-2-Channel-Bluetooth-Automation/dp/B07V6GV8XD?th=1

Good luck with the quick sell.

Those speakers will be gone in nano seconds at $1,500, old crossovers or not.

Eight watts is not much power , it’s a level of power that will leave many systems prone to clipping, especially at any appreciable distance. Certain music and special effects can be enhanced to an exhilarating level of pleasure and intensity when played loud . We may not want to listen at the higher levels for long , but sometimes shear unclipped power is the secret recipe for delivering a moving and memorable experience . All things being equal ,power is a good thing ,as is the high efficiency that our speakers deliver .
Low wattage amps are enough power for a lot of Klipsch users due the the high sensitivity of the speaker and size. It is like a sports car, just because it can most people won't be running their system that hard toward clipping. With room gain of easy 10 db, there is some free headroom.

This has not been my experience with amplifiers that can switch between triode and ultralinear or pentode.
Perhaps you mean gain?
Yes, the gain in switching produces more output from the amp and first perceptions are the the increases in volume/gain may be laperceived as better but, longer listening ends with fatigue due to the Hi's im many cases. Ultralinear delivers more power and promises no more. Tubes that are meant for pentode or beam triode will work well in most systems. All the ultralinear amp that I read and know about have more power in ultrilinear mode. The power tube is used entirely different than in tirode mode. The KT 88 pair can produce nearly 100 watts even pushing low ohm speakers..

I started my tube journey over 10 years ago with a hybird Yaqin 2100 amp with tube preamp and SS rear. Excellent amp along with several of the EL 34 amps which are exceptional for the money. I have never owned an American tube amp but, have owed several Mc Intosh amps, SS for comparison. Fast pace and to 2024, I am on a 3rd tube amp, lol. Not funny, lol. I tried the OldChen K3 Kt88 twice with the same transformer failure. More on that later if interest. China Hi Fi refunded my money with no problems.
This brings up the Willisenton R8 KT 88 amp. It is a moderate priced amp and a back breaker going on 60 lbs. The topic is tube rolling and this is the easiest amp that I have ever had that you can audibly hear a change with multiple tubes, preamp and power. The bias adjustment take about 10 second for a power tube and not needed for the preamp tubes. Preamp tubes for the amp are Willisenton 6sN7x3 , PS Vane Fever CV 181z, Shuguang Black Treasure CV181z, and Willisenton 6SL7. The rolling power tubes were the Shuguang Black Treasure KT 88 , Willisenton KT 88, PSVane KT88, Tel Funkenl Black Diamond EL 34, and an old quad pair of Sevlanta 6550 C winged quad on a trade for my NOS Tung Sung EL 34 tubes.
Well, I am very impressed with this amp and it's sound. The tubes can make or brake a system. This amp has very noticeable changes in tube rolling and can be transformed by tube rolling. I did all my listening in triode mode using just a few watts. I am not going to bash stock tubes because they most likely come from the same factories and are not inherently bad.
The change of the Power tubes changed the bass and lower midrange. Where as, the preamp tubes influenced the midrange in this particular Kt 88 amp. The point of the post is the fun with rolling, not the cost, lol. and the quickness for comparison. These topic are always so biase and less than scientific. because it took 20 min. for the tubes to warm. This thread is not that serious. What's your take? I did find some nice combo with my current tubes without spending more money. The old motto is nothing exceeds like excess!
See, I did not tell you about about magic tubes, the must have amp, system . or made SS comparison. Just roll with it.🥴 Rolling is not like steak or lobster, it is more like skirt steak vs t bone?

There are a lot of things going on between SS and tube gear. Tube gear can't have the accuracy of SS due to the tubes and design. Tube integrated amps usually will handle 4 an 8 ohm loads. That can and can't be the case with SS avr, and integrated amps. Tube amps can operate with different tube and design factors that can affect the sound. Impedance swings should not be a major factor unless the amp / speakers are grossly mismatched. Impedance fluctuates widely.
Additional watts for the most part are about bragging about a big beast when only a fly swatter is needed. I have class D, Class A/B and tubes, I have driven my RF 7 's, Forte, Mc Intosh speaker and other with 25-1000 watt amps. No real diff with gain adjustment in my listening levels.

RF-7 II next system upgrade?
in Home Theater
Posted
Do you have the RF 7 II's or I? The RC 64 can work with any of the 7's with some EQ which is almost universal with many avr's. You could do a phantom center and not loose much without a center speaker and wait til you move to completer the HT.
