Satelites/subs containing high end caraudio drivers

[FE3T]

I am considering building a pair of satelites/subs of some car audio drivers i have and would like some comments from people more experienced with DIY prosjects.

The Mid/high driver:

Pic shows Macrom`s 4 inch Integra driver. made by Morel.
The cone are driven by a 54mm coil of aluminium wire and 3 stacked ferrite magnets.
the 28mm dome have Neodym magnets and have a damping chamber within the magnets driving the bass cone.
many will consider this a High end car speaker.

Mine have a bass sections from a pair of 58.10 midranges and sound similar, but should have a lower QT making them suitable for use from 200-250hz in a small sealed shamber

The Midbass speaker:

Macrom 59.17 165mm. made by Morel
simulations show a qt 0,71 in a 13L sealed box and -3db at 80hz.

It is very tempting too use 2 pcs Hypex Active 3W plate amps with x over modules for 250 and 3200hz for these speakers.

Subs


Rockford Fosgate RFR2212. this is 12inch woofers with dual 4 ohm 4 inch voicecoils.
I have 2 of them and plan too use them in 2 low Q sealed boxes with Hypex HS500 plate amps.

Have anyone played with similar combinations? and where the results satisfying?
