Can you tell me what's on your spec sheet?

Having tried the Perfect 10.1 in the car both sealed and ported for almost 5 years and recently tried one ported in the home I can surgest some designs.

As Paradice_Ice (hi mate

) said they do take quite a bit of driving.

My advice is go for 2.0 cubic net ported to 25 hz, this should give a f3 of around 22hz.

Use twin 2.8-3 inch vents or a single 4 inch vent, less vent cross sectional area than that will give you port noise in the 28-20hz region.

The perfect 10 does NOT need high power unless its a sealed enclosure. I powered it with 100w amp. and it played quite nicely in a small room. I currently use it in a passive radiator setup with a Peerless 12" radiator in a 2 cu ft enclosure running @ 300w RMS flat response from about 120hz down to 23hz in a medium sized room.
