Pearl Acoustic Sibelius

On the same theme of a slightly off cabinet... Just discovered that my 10.3s are in Pensils designed for 10p. They came to me second hand.

Any idea how that mismatch would translate sonically? Less deep bass & bump higher up vs the Pensils intended for 10.3?
 
A lot. A10.3 traded potential bass extention forbetter mid/top and gretaer sensitivity,

A10.2 should be a much better match for the Sibilius clone, but i would stillprefer the better mid/top — just put it on a box it was designed for.

Looking for something comparable or better than the Sibelius. Covers all bases from low35hz-mid-high nicely, no compromises. Would this FH3 with MAOP 7 be the one, no? re: KJFAudio options:

acko,

All loud speakers come with compromises, and a wide-band single driver speakers have their fare share.

We have to acknowledge that these are all modestly sized cones, and low frequency output will be limited; the MAOP 7 has a smaller cone area vs the Alpair 10.3 or Alpair 10.2, so it will be able to move less air, and this will impact perception of low frequency output. Even if a smaller driver can be tuned lower in a particular cabinet, it will not necessarily provide the lower bass output at SPL that the listener might desire. And my post does not imply that the MAOP 7 in the FH3 cabinet can play lower than the Sibelius. 🙂

Actually, was looking at FHXL initially but driver choices are different, re:KJF site

… and then this top end MAOP 11, IIRC Dave (planet10) indicating somewhere sounded a bit weird?
 
I think FHXL would get you closer, but that's just a guess, and based on similar drivers, ie A10.3, 10p, MAOP 10.2 etc.

Each with its own strengths and limitations. All these are like EOL already. Now, there is a whole plethora of new CH series promoted as low cost products but I cannot see any details on performance on MA site. How do we choose them for a particular application?

Good question. A smaller box will give you a tight and not so deep bass.
Larger box give you deeper bass and not so tight sound.
You can tune the box to a higher frequency. You can then get a hump there on the frequency curve. It can provide more bass at this frequency. It can even lead one to believe that they go deeper than they do.
I prefer a small baffle because such a box is easier to disappear in the soundscape. Beveled edges on the baffle are preferable and that helps. Diffraction decreases. 45° edges.
If you think that low bass is important, you should choose the FHXL. That box goes the deepest.
