Sealed Box for Monacor SPA-110PA

[Buehgemeiste]

Hi,

i would like to use the Monacor SPA-110PA as a mid-woofer.
it should play loud and flat between 100Hz and as high as possible (maybe 5kHz are possible).
it should really be one single box for each mid-woofer.
i do not want a classic pa-top that has one or two woofers and horn in one cab.
I copy-paste the parameters from the manufacturer's site:

Impedance (Z) 8 Ω
Resonant frequency (fs) 61 Hz
Max. frequency range f3-5,000 Hz
Music power 300 WMAX
Power rating (P) 150 WRMS
SPL (1 W/m) 97 dB
Suspension compl. (Cms) 0.23 mm/N
Moving mass (Mms) 29 g
Mech. Q factor (Qms) 10.68
Electr. Q factor (Qes) 0.49
Total Q factor (Qts) 0.47
Equivalent volume (Vas) 38 l
DC resistance (Re) 5.2 Ω
Force factor (BxL) 10.4 Tm
Voice coil induct. (Le) 0.68 mH
Voice coil diameter 50 mm
Voice coil former Kapton
Linear excursion (XMAX) ±4 mm
Eff. cone area (Sd) 364 cm2
Magnet weight 1.2 kg
Weight 3.2 kg

I have used different online-calculators and the consensus seems to be, that slightly more than 30 litres should be ideal for a sealed enclosure.
I aim for a cuboid form, but i read about problems with standing waves.

would a simple box with dimensions of 30cm x 30cm x 35cm work?
what do i have to watch for designing a cabinet like this?

Only thing you got to worry about is the box vibrating and coloring the sound, so make it nice and rigid, line it with damping material and you're good to go.

i´ll try it like that!
i also plan to add an speaker grill.
is it ok to sink the baffle 3cm into the box?
(i don´t know how to explain that in english)
or would it somehow influence the sound?
is bsc predictable in this case?

Yes on the recessed baffle but BSC is not used in pro sound speakers, if you need to contour or correct the response use DSP.
