Can you commment on this xover?

This is the xover of the mid of my Living Voice Avatar speaker. The driver is Vifa paper cone which has a part number of ..17.. something which I forgot. The configuration in D'appolito.

I'll try to draw it out here since I don't have a website.

-----------------------------LLL2------------------------- +

CCC1 RRR2 |
| | |
| | |
LLL1 | | 2 Woofer
| | |
| | |
| CCC2 CCC3
RRR1 | |

-------------------------------------------------------------- -

These are the values: LLL2 = .974mh
LLL1 = .303mh
CCC1 = 22uf
CCC2 = 1.5uf
CCC3 = 10uf
RRR1 = 10.12
RRR2 = 3.5

My question is that I always feel like the speaker is a little lean and overly damp in the mid bass. Are there anything I can change to improve on the midbass?

It looks like my drawing got messed up. Maybe I can try to say it in words:

Input + First CCC1 LLL1 RRR1 is a series LCR circuit in parallel with the input. Let's call this LCR1.

Then LCR1 is in parallel with LLL2.

LLL2 is in parallel with RRR2 + CCC2//CCC3.


I can try this:

---------------LLL2----------------------------- +
aaaa|aaaaaaaaaaa|
aaaa|aaaaaaaaaaa|
aaa CCC1aaaaaaaRRR2
aaaa|aaaaaaaaaaa| 2 Woofer
aaaLLL1aaaaaaaaa|--------
aaaa|aaaaaaaaaaaaaaaaa|
aaaa|aaaaaaaaaaa|aaaaa|
aaaRRR1aaaaaaaCCC2aCCC3
aaaa|aaaaaaaaaaa|aaaaa|
---------------------------------------------------- -

I have insert the "a" letter so that all the white space get deleted.
Sorry for the messy drawing.

You don't need a website. You can draw it, save it as a .gif and attach the file to your post.

I think the attached file is the xover in GIF format.
