This may be a part out speaker. Drivers, horns, and crossover. If all working, maybe 500.00.
Tweeter, mid, K33, and crossover. Depending on what is installed. And if all three play.
It could be a K55 and crossover. -
Looks like a pair of RCA bipolar transistors. Since amp is mono, push pull.
I would not pay 500 -700 for a single in that shape. But do not need one either.
-
That horn fits a La Scala II. Maybe others with the Z brackets.

Like my Super Heresy mod, it's nice to see something I wrote over 6 1/2 YEARS ago is still being discussed and acted upon in the name of better sound from some great Klipsch speakers Paul created that have withstood the greatest test of all.................the test of time (and many ears).
Is the 15C driver an upgrade in recent vintage Heritage speakers?
Looked at Parts Express and they show in stock. Reasonable too.
Always interested in improvements. But extremely satisfied with as is.

I use tin plated brass from a local electrical supply. Needed a dozen, biwired instead of using the jumpers.
New setup AK6 uses is nicer than the LS II input panel.
The cables are Star Quad. The AK6 is wired internally with Star Quad.

The mass wholesalers take a shipment of the discontinued product. They do not care if you want one, three, or a dozen. Shop from the pile.
Price seems high. That is 1,750.00 or so for a pair. Maybe Europe pricing is higher, but that was MSRP here before H IV.

The banana plugs okay. I just feel they are marginal. Spade lugs allow for tight connections.

Very neat dressing on the leads. Hate to see bananas used on speakers this nice.

Looking good!

Did you try an LME49740?
Mark changed the amp to a Fet input type because he increased the input impedance of the diff to single ended input to work better with tube preamps. He upped the input impedance to 47k from the 10k standard. I agree that the limiting factor primarily on the slew rate(speed) of these amps is the output devices. I was able to get mine up to about 10v/us be careful changing of compensation throughout the amp.
This was the first one tried. Hoped to hear angels singing. To my ears the dac sounded the same.
The dac uses surface mount chips. Swapping these in and out was challenging. -
I doubt the use of MC33079 is a weak link. I have a dac that uses them on all balanced outputs. Replaced with every higher specced quad opamp I could get.
None made an improvement. Some degraded the sound. Tried bipolar and FET input types. Ended up going back with the MC33079.
They are old and cheap. Crown and others used this part for a reason. There were lots of options.
Changing out the opamps may not do anything for rise times. The output stage may be the bottleneck.

I revised these to 1998 manufacturing - these are the 1st consecutive pair of Klipsch Belle Oak oil veneer speakers made at the Hope Factory between the 07-06-1998 and the 07-12-1998 -
so these speakers are 22 years old ---------and the Belle was discontinued in 2005-2006 as the sales were very , very low
That has always confused me. A good friend bought his Belle’s in Corpus Christi after demoing La Scala’s and K-horns. Bought the top Yamaha separates to drive them. He liked the sound of the Belle’s better the La Scala’s and his apartment did not have two corners for the K-Horns.
The size difference between Belle’s and La Scala’s should have helped sales.

Thanks guys. All good advice and appreciated. I will look into doing modifications in my setup.
Edit: I ordered a VTI BL series extended height audio rack, black frame & caps, 4 cherry shelves.
Does it stack together?

Actually, with the K-400 on the front, the time delay is worse, bit it isn't as noticeable as the mid tweeter distance. That's why my tweeters are placed towards the back of the cabinets, with the mid/tweeter diaphragms lined up.
Have you considered sticking the K77 back in the cabinet?
It would make it appear you have addd the tweaks and a super tweeter.

I have LS II with DaveA’s latest horn and DE-120. This is awesome.
I THINK the K400 and Driver are fine. The bass bin too. But due to length of the folded horn the horn can only load the driver so low. The change in expansion rate buys some but the bass response is falling hard by 60 Hz.
My thoughts are add a sub. Either a horn (huge) or sealed box (inefficient) to match easier.
I have relistened numerous times to the LS II full range and then crossed at 60 Hz to several subs. It is no comparison. When you feel and hear the sub kick from time to time there is no going back to full range.
I think subwoofer selection is not difficult. But no 30 - 40 pound weenies. Get a crunching bruiser. The cheap lightweight subs are famous for one note bass.
The crossovers in the LS II are a big step up from the older models. There was a change in the LS II crossover to bring the level of the K400 down a few dB. Happened prior to the 70th Anniversary model run. Might be all an older one may need. Never heard of a factory retrofit though.

I have had the a-s1200 for a couple of weeks. Got it on Amazon, had to wait a couple of months but they had it for $1,560 new so I couldn't pass on it. Sounds great with my Technics 1500C, E-30 DAC and La Scala 2's.
I have to assume the A-S1200 is awesome paired with La Scala II’s.

But rate us a bigger variable than AAC or MP3. If 96k or less AAC makes an improvement. Better lossey reconstruction. Once above 192K the evaluations say the sound is the same.
I only use 320k feeds. All I have located are MP3.
This is what I use the Sangean for. Find the high resolution internet eadio stations.
I have only searched for Jazz and Classical. Found more than 15 stations for each.
One day I will do again. Takes an hour to sort through 600 Stations to check bitrate.
Think the listing comes from Recievia. Not sure what they do for a living. But is still updated.
Audiophile Audition is Psychomed. All 320K.
Listener supported, no advertising, they have 6 streams.
Baroque, Classical, Jazz, Lounge, Rick - Blues, and Extreme Live.
Only really listen to the Classical. Next to Radio 3 it is the best I have found.
But the Jazz seems to match CD quality. Lot of European artists.
Wife likes the Lounge.
I would prefer a blues and a rock. But blues might get like Sirius running 24/7. Seems like A Blues station anyway.
The Extreme Live seems more New Age or maybe World Music.
Think the stream names are a guide. Running 24/7 programming leaves slots for alternatives.Keep wanting to order Qobuz. But letting someone else select the tracks is better for me. I end up listening to the same songs after a while.

I picked up a Sangean WFR-20 about 12 years ago. Feed some active monitors in my office. OK sound.
One great feature is it downloads 1000’s of internet stations on power up. Various sorting options. Displays bit rate and if multiple streams are available.
Do not use it for serious listening, but to find 320 kB streams. Once selected stations with multiple streams are all visible. Use the big rig to play them once located.
Psychomed from Greece has several bands. I find the classical great. There are rock, jazz, blues, several others. No compression too.
320 KB MP3 is almost CD quality.
I am using a way too complicated player. But sounds great.
BBC Radio 3 has fantastic programming, but the 320k feed is UK only. Linn and Naim have 320k streams too. Not near the programming of Psychomed though.

A good friend had a 9090 B I thought, purchased around 1975 or 1976. Used it until he passed away.
He had issues with jacks. Might have been ham fisting the AUX inputs. Seems like he paid a tech to repair several times. This was early CD player times, plus plugging in the TV to listen to MTV.
It was impressive. Way better than the junk I had then.

Looking good.
Assume each section could get smaller as you stack it up. The pictures of the Fastrac Kit looked that way. Would save some board feet of lumber.
Lastly, if overall is 10” from 8” horn and 2” adapter will this get down to 400 Hz? I think the Belle squawker is about the same depth.

Resale is always driven by what the buyer is willing to pay. The low cost models like VTV usually hold resale better. If it drops 500.00 in a year that is a lot. If a 3,000.00 amplifier drops 500.00 it is peanuts.
The VTV build quality may have ramped up recently. They seemed to be at the bottom. But are put together here in the USA. Cheap price and US assembly usually do not go together.
The Hypex modules measure better than Pascal modules. But at least one manufacturer uses the Pascal in a really expensive integrated because they feel the output filter can be less complex. Which they feel sounds better.
All Class D amplifiers have a filter on the output to remove the high frequency artifacts. Most of the published measurements are made with an additional bandwidth limiting filter to ignore leakage past the output filter.
But no one listens with the filter that is used for measurements.
One hard fact is there are a lot more products using Hypex, Ncore, and iPurifi modules. I guess that means they are better.
I wanted a VTV iPurifi and a Pascal amp. Cheap and USA built.
Also wanted;
Benchmark AHB2
MacIntosh 462
Orchard Audio BOSC
Denafrips Hyperion
This week added the Lyngdorf TDAI-1120 to the list.

As I sit mesmerized by the Atlas drivers in my LS II is there a reason to swap? Guess it is one of those you do not know what you are missing until you hear it.
But I would be the last person to doubt the quality of Italian compression drivers. The B&C DE-120 drivers made a large improvement. Has anyone replaced recent manufacture Atlas drivers with K-55G?

The wave of the future. Class A myself, at least most of the time but all of them A, AB and D can be made to sound really good. Class D has made tremendous improvements in the last decade.
The Hypex modules used are first rate. I am sure the Marantz engineers are wringing excellent results from them.
Still have one or two Marantz SACD players in the attic. Still a fanboy. But the Marantz integrated I want is several times the cost of this one. And the disc player would go straight to the attic. Do not play the silver discs. Only copy the files.

I use an original iPad Air. No updates for a year. But works fine.
Also the Nuuk waterproof cases are 10.00.
