A center channel for the LS?

[Alexander]

 

Just thinking out loud. Has anyone put any thought in making a center channel out of effectively the “top hat” of an LS? In other words build a stand alone top half of an LS with just a k77/k400*? Not sure how much information is used on a center below 400Hz though. Maybe use a passive pair of 8“s or so in a sub for the bottom end that could be placed elsewhere?

 

*k77/k400 would be matching what ever you have in your LS mains of course.

You'll need something to supplement it, there's a lot of sound/vocals below 400Hz.  Why can't you use an entire LaScala?

Easy way to find out...

Michael and others have.

Hookup center and use full range and without bass bin attached to cross over.

I'd advise using a whole, matched La Scala.  We have a Belle Klipsch (designed to sound similar to the LaScala) in the center, sunk into the wall to flush mount it.   It works great!  Since it was going into the wall anyway, creating more room to the rear (in our case, in to a bump out, sticking out on the other side of the wall), we built a new top hat with the longer K401 mid horn, so the timbre would be more like that of our flanking Klipschorns.  We have an acoustically transparent projection screen that lowers in front of where the Belle Klipsch is hiding behind the wall covering grille cloth.  The Belle is EQ'd to compensate for the wall covering grille cloth and for the screen.  That makes it very slightly bright when playing music, rather than running a movie, but it is fine, and the EQ is above 10K Hz, where some of the family and usual guests have attenuating or absent hearing.  It's a story as old as (audiophile) time:  by the time you can afford good speakers, your hearing is rolled off a bit. 😐 

 

Lacking all that, a properly designed ported or sealed large DIY box with a big speaker in it might work well.  The parameters are online somewhere.  It should be floor standing with your top hat on top, or on top of your display (or behind an AT screen, if you have that).  You really can't put a 400 Hz crossed over unit "somewhere else," because you would have at least two octaves of bass that the audience could easily locate ("Hey, the bass part of Sam Elliot's voice is coming from over "there!").  Most X overs to a sub, for instance, are 80Hz or below, where bass is more non-directional.

the Industrial LaScala had a split version  had a K400-K401-K77 in the  top hat with the HF and the LF on a terminal cup  -

Thanks gents, kind of figured that the 400Hz “sub” was to high and would have been too easy to pin point its location. Unfortunately a “third LS” as a center is just out of the question – real estate & the woman ya know. So it looks that the klf-30s & klf-c7 will have to stay in place for the HT duty's with the LS sit on the ends dedicated to 2-channel.

you have seen this?

Would possible an exodus anarchy sub work? Narrow enough to fit flat with doghouse on top. (7.5inches wide) Been looking at building 2 to supplement some 2 way surround speakers I am  building.
