Hi! I’m looking for some advice if BMS 15n630 can be used in closed box of approx 80 liters for subwoofer duty? The high Fs of 39 concerns me, so a «standard» Q of 0.7 in the 80 l box simulate a f3 of about 75Hz... A BR box of 90 l will help the response down to approx 45 Hz. I would like some more extension, preferrably closer to 30 Hz. I know the room will help. And EQ could also compensate, but I can only adjust the crossover frequency (Parasound Hint + bridged Behringer for the sub).
Any thoughts or advice is appreciated!

Have a look at the BMS 15S430V2 for subwoofer duty. Lower qts, stronger motor and 4" voice coil. The 15N630 is more of a midwoofer-low midrange driver judging the driver parameters.
Prices are about the same.

One year has gone, and I am enjoying my subwoofer with BMS 15n630. The box ended up quite big, 180 liters BR tuned at 24 Hz. The plan was to hide the sub under the sofa (High WAF) so the dimensions were dictated by the sofa: 150 x 75 x 24 cm. However, the roomgain was too much and the bass lacked slam. It had a lot of rumble and the kids loved the vibrations. Luckily the subwoofer fitted perfectly behind my 65” TV, and the bass became much better. Now the bass seems «fast» and reaches far down - subjectively flat to the low 20-ies and response down to 15 Hz on frequency sweeps. Power handling for my use is still plenty in the big box, at LOUD levels I measured 15 V from the amp, and the woofer is still within xmax. I am happy with the results 🙂
