where? please links,please.

 

Here is a little one <link>

 

Not exactly low output either, it would give a pretty good sized pro sound cabinet a run for its money.

Nemmeno con un'uscita esattamente bassa, darebbe un buon guadagno a un cabinet pro sound di dimensioni abbastanza buone.

100db at 40hz is phenomenal

Wonder how it would do in the anechoic chamber at Klipsch?  or outdoors in half space?

Ti chiedi come farebbe nella camera anecoica a Klipsch? o all'aperto a metà spazio?

The same that an LS would do

No, solo la differenza di risposta in una stanza chiusa o all'aria aperta è la stessa ... tutto cambia

 

Forgive me if I write badly, but the translator works badly.

La Scala is not known for deep bass.  The bass horn is too small.  The compromise is punchy bass.  

If by "punchy" you mean the 140 Hz. +7 db peak, with the anemic response of the K33 at 400 Hz. (vs. the "best bang for buck" Kappa 15C), you are correct.

The La Scala bass bin is a short horn, subs are a different design.

 

At the expense of output.

 

Small driver, small horn = low output.

Ah yes, PHYSICS, the enemy of all wishful thinkers, worldwide!

here's a sim of BFM's T18  - nice in a corner plus an outdoors measurement of my Peavey FH1 (much like LS/Belle)

The best you can hope for with an unmodified speaker can be done by tone controls.  Otherwise you could look on the forum for the port modifications and / or crossover changes though you will not get deep bass with the standard horn loaded enclosure.

what is a punchy bass   you mean light bass

does the  Kappa 15C give a better deeper bass in the SCALA vs a K33 or  k43, I have 3 LSI , they all have the K43

as far as bass ,  I have Scala's and no the bass is definitely not punchy , it's ok    , now Cornwall is better and deeper  , and Chorus 1 or 2 is even a step  deeper  than a Cornwall  , the bass is tight , and really punchy --

In 2007, I got 4 MWMs bins with 2 gauss woofers and 2 K43's. I put the K43's in my LaScalas and discovered the much greater MIDRANGE definition from that woofer. Vocals, saxophone, guitar became exquisitely detailed. If you are using those, I would just keep using them. I came up with the Kappa 15C as a brand new, best bang for the buck alternative, which has a teeny bit better midrange definition than the K43, but not as much power handling. K43's are a great driver for a LaScala, for those who use SUBWOOFERS with them.

FWLIW - hornresp looks similar between one K33E spec and the four ohm Kappa 15C.  Group delay is lower for Kappa down low.

I wonder the 15C how it can have a deeper bass when it has a higher usage frequency than the K33, maybe it will have a more incisive bass

Deeper bass how?  That graph show half the output at 60 Hz for the 15C compared to the K33.
