BEST HORN LOUDSPEAKER TO PURCHASE

Hey KJL.....I own the Klipsch Lascala II and likewise prefer lower volumes. Additionally I use the SVS SB2000 as my sub. Obviously the newest rendition of the Lascala is pricey and the older versions suffer from weak side walls and the one box vibration issue which muddies everything. Klipsch obviously realized this and separated the bins and attempted to isolate them with rubber feet between the two bins. Upgrading this separation with something like isoacoustics and get ready for a clarity upgrade. Getting them off the floor onto isolation dollies helped too since my floor is as responsive as a drum skin. But my main point is Lascalas at very low volumes are delightfully crisp and live sounding. The mid range is so lifelike as to shock visitors. All this at under 70db which is kind sad since these speakers if feed a mere single watt are rated at a sensitivity of 105db. Pity the system with any residual hum, buzz, or hiss or any kind. You will be provided an intimate window into your electronics with little veil but as a result every nuance is laid bare in each recording for better or worse. All at 55db. Used market occasionally has them. Klipsch Lascala II. 

It would be nice if you lived near me, Plainfield, 07062.

You could borrow one of my 3 Chase RLC-1 Remote Line Controllers that has low volume features that I think will improve things for your low volume listening.

It’s primary function: add these remote control features to any system with manual controls: remote power; volume; mute; balance; treble; bass; select any of 4 line level inputs. Either optional use thru a tape or processor loop, or use thru any line in.

Low Volume Feature: As you lower the volume below it’s default low volume start, it automatically and progressively adds bass boost. Lower a bit more, it boosts bass a bit more. It has many many small increments up or down. Raise the volume, bass boost automatically lessens, and does not occur after you exceed the default low volume start. (note: no treble boost that Fletcher Munson also does).

Setup: Chase at default low volume start.

Your Preamp Volume: raise to your normal volume whereby no bass boost is needed, never change that.

Now use the Chase to lower or raise the volume.

When I listen to Jazz at low volumes, this feature is what keeps the Bass Player audible thus still part of the group, much more enjoyable.

here is the inside of one of mine: no moving parts, a single Philips processor does everything, it is noiseless at 105 db s/n ratio. I was adding a toggle on/off switch to the front panel, as the unit has remote standby, but it needs full power off to reset to defaults which I like to do occasionally. Otherwise, unplug it, add a power cord switch, ....

I use one with my Vintage 15" woofers and horn mid and horn tweeters in my main system; and in my office system and in my garage/shop system.

Perhaps, do some AI research about Transmission Line Subwoofers.  They may (or may not) provide an alternate solution to your SVS subs.   Here’s an example for sale.

A bass wave at 55 Hz is 6.25 meters long. A bass wave at 35 Hz is 9.7 meters long.

Quality bass response at your listening chair, @50-55db, is a physics and mathematics challenge.  With some homework, it can be figured out.   Good luck in your quest.

Have you made sure your speakers are wired in phase?
