I'd calculate it, using Russian version of John Ratter's xls file.
next time I'll tuning it higher - to 70hz and will use it with subwoofer. furthermore I will install tweeter.
thank you for your opinion about finish. it's my first hand not marble coating.

Hi,

By implementing a filter, cutting back the midrange, you can improve treble.

Yes, that finish is very impressive. Wish I could do them like that.
I think this might be why you're finding the response a bit iffy. MathCad predicted response for that enclosure, using the SP-200X. I damped it down a bit with stuffing in the first half of the line. Nothing you can do about the big hole though. Pretty good for a Weems-based pipe though. Obviously the Monacor mates well to the Weems calculations.

it's should be, but I think 200 Hz hole are smooth out by damping material inside.
another trobles - hump from 7k to 10kHz. I'm just hear this and it's annoy me.
Yes, the SP200 is a bit hot across this region. Short of mechanical modifications, you'll need a filer to bring it into line a bit. You can reduce the hole to only 15db by stuffing the first half of the line with 1lb ft^3 of Dacron or similar.
Hi,
Nice speakers! 🙄 In my opinion, don't use filter until it is properly broken in.. I use these drivers for almost two years and I can say that they got a lot better after breaking in. It also takes some serious time though.. Tweeter is necessary IMHO.
Good luck Martin

which tweeter do you mean? I try to set up a few, but it's almost nothing. small sensitivity.
how did you use it? TQWP? sealed? ported?
I won't use filter, but ...
Hi,
I use Eminence APT80 tweeter, filtered with some small capacitor (0.5uf + attenuator).
Here you can find something about my speakers http://www.diyaudio.com/forums/showthread.php?postid=747969&highlight=#post747969
Let them play for some time, I'm sure they will get better , than you can decide if you need filter or not.
