Often, these small amps are SE with high Rout, an amplifier that will be much happier with a loudspeaker with a flattih impedance curves.

I have seen NO measurement of a Klipsch impedance (with the stock XO) that anywhere near stisfies this metric.

They may be efficeint (typically rated about 3 dB than they really are), but not really suite dto a high Rout amplifier.

 Crites does some aftremarket XOs that fix this issue with some Klipsch.

Paul Klipsch often said:  " What this country needs is a good 5 watt amplifier ".  Some of the best sound I've heard with Low Wattage is with high quality SET amps driving modified K-Horns.  Most speakers cannot match the K-Horn dynamics.

You will note "stock” in my comment.

They really need a DSP XO to get any sort of time coherence.

Low Wattage setups often lend themselves to tweaks/modifications.  K-Horns do need modifications to get them to sound their best.  Once modified,  they can provide some serious dynamics with some degree of realism.

K-Horns are limited to rooms that have a pair of usable corners in the right place so suited to few. They are also BIG.

Yes. That's why they have great dynamics.  :thumb:

The Spendor A1 speakers are excellent with the FirstWatt F8 amp, rated 25 watts at 8 ohms. There is nothing "electronic" about the sound. They are sealed bookshelf speakers in the BBC tradition (but a modern product, not aping the BBC monitor rules). The system plays as loud as one could want in a room of 75 cubic meters.

And even then only go down to 40 Hz.

What are the corners requirements to a K-Horn?
Its only clear space?

The corner extends the size of the mouth of the horn. Other examples are Frugel-Horns, Woden Monoliths, RonHorns…

Read once that the corners should extend 9 feet for full effect.

I'm pretty new to the high efficiency speaker low watt amp approach. 

That being said I have a new to me pair of Klipsch Lascala Industrial splits.  I need to replace the tweeters because one of them is non-functional, and I intend to replace a few crossover capacitors to bring them up to spec. 

I will be driving them with a McIntosh C250 amp, which I know is probably considered high powered for this thread, but the low power tube McIntosh amps are too expensive for me at this time. 

Currently I am looking for a good tube pre-amp with a nice phono stage that will pair well with the MC250 to provide me the low volume sound quality that I am after.  Maybe someday in the future I will purchase a low power (less than 30w) tube amp to power my LSI just to see if there is a huge difference or not.  I've been advised that the MC250 sounds very similar to the McIntosh tube amps of the same era.  I will likely be adding one or more powered subwoofers to fill out the bass response below 40 Hz.
