which enclosure for monacor SP-80x

[Spassgeneral]

Hello,
I have got a pair of Monacor at eb.y for just 1 ! Euro.

What would be the best enclosure for it?

I am thinking of a tqwt but i'm not shure. the Martin Kings don't look very promising.
any suggestions?
the tsp for the drivers:
fs: 50hz
re: 6,8 ohm
SD: 206 qcm
vas: 59 lit
qes: 0,58
qms: 2,3
qts: 0,463

best regards

Greets!

Well, just plugging in the numbers this ML-horn looks promising:

L = 57.42"
zdriver = 20.47"
zport = 54"
SO = 31.93"^2
SL = 255.44"^2
rport = 2.5"
Lport = 2"

All dims i.d. and approximate.

Hey!
that looks great!

unfolded a bit high, but slim.
I think WAF is O.K.

Cool! Please let us know how they turn out, any tweaking details, etc..

I made a mistake calculating the measures from inch to cm. I have to multiply by 2.54 twice. The footprint is about 30 by 55 cm ! this is too big.

which king sheet did you use? I tried to recalc Your dimensions, but the result as very poor. I used either the wrong sheet or it is just too old.
My sheets are several years old, from times they were for free for personal use.

Hmmmmmmmm................

40hz looked to good to be true.

Same as you, the old freeware (PORTED in this case) for quick sims to post since they don't take near as long to calculate as the new ones.

FYI, here's the converter program I use: http://joshmadison.com/article/convert-for-windows

Did you use the correct BL value? Since it wasn't posted, I calculated it: 6.1635 N/A.

Also, I used a 0.3 lbs/ft^3 stuffing density along its entire length.

Anyway, as you've already learned in your earlier sims, if you want a relatively smooth response and go low it will require a large cab since its Qts is too high for an optimum vented alignment.

FWIW, here's this cab's Vb converted to a 125.894"^2 (~812.22 cm^2) MLTL:

what about this?
MLTQWT Geometry Definition

L=40
Driver Pos= 0.45
So=3.4
SL=3.4
Density=.25
Portradius=2.5
Portlength=1.5

I think the size is o.K. so
any argues against this enclosure?
