Could this sub work?

[blackreplica]

Hi all,

I'm trying to design a suitable enclosure for a pair of subs i have lying around unused at home, their specs are as follows:

Normal Power Handling 300W rms
Voice Coil Diameter 3”
Voice Coil Type / Former edge wound/Kapton
Resonant Frequency 43Hz
Qts-Total Damping 0.52
Qms- Mechanical Damping 2.51
Qes- Electromagnetic Damping 0.66
Vas- Equivalent Compliance Volume 43.97 Liter
DC Resistance of V.C. 4W / 8W
Sensitivity(SPL at 1W) 89.31 dB
Linear Excursion ±5.5mm
Peak to Peak Excursion ±13mm
Mms- Total Mass 114.7 grams
Sd- Piston Area 0.0512 sqM
Bl- Magnet Product 13.74 TM
Diaphragm Material carbon fiber/Nomex honeycomb
Basket Material cast aluminum
Net Weight 24.18lb
Dimensions 12.27” dia. X 4.75” H
Mounting Diameter 11.125” dia.

What kind of enclosures would you guys use? They will be used for music only.

As Qts is high you have no choice other than sealed or open baffle. Given the lowish Xmax I'd go for sealed. Fs is relatively high so you whatever you do it will be more of a woofer than a subwoofer.

thats what i was thinking really. it models alright in huge ported boxes but i want to keep the enclosure size within reasonable limits. OB doesnt seem like a good idea due to limited xmax, and this thing rolls off way too early in a sealed enclosure.

Just in case anyone is wondering, these a actually car subs, PPI Flat Pistons, one of very few car sunds that actually have underhung motors. I love them in car(where there is plenty of cabin gain to compensate for low end extension, and they shine in ported boxes tuned to about 35Hz) but in a home environment, i wont be able to get away with that.

I already have the subs, and i want to use them in home....sane or wacky enclosure ideas are welcome 🙂

If you don't care about lower SPL and you got a big amplifier, you could go isobaric to get a smaller ported enclosure.
