That .2" isn't going to amount to anything in most cases.
The cutout holes are very flexible in their sizes. You could
probably have a cutout hole an inch smaller than what may be
specified and it would still work OK. As long as the frame
has enough 'wood' to 'hold onto' when mounting it, that's
fine. Inversely, on the small side, as long as the basket
can freely clear the cutout hole, that's ok too.
If your current speaker does have a long throw, then yes,
that is certainly something you DO need to duplicate on any
potential replacement. As long as you get a decent subwoofer
driver that states "long throw" and has a good size magnet,
you should be fine. The magnet is the most expensive part of
a speaker and a big magnet is not going to be on a cheap
speaker. Look for an Fs for a 12" sub driver of 23hz or
less, on a 10" sub driver look for below 29hz. Also one with
a rubber surround would be of better quality usually. If it
does not state 'long throw' exactly, look for something like
"bumped and vented pole piece" or a line similar to that, and
also compare the Xmax values between prospects. The larger
the better, this is the distance the cone can travel, known
as the cone excursion (as in "long throw"). Anything over
.5" (12.5mm) is a good bit.

I looked through MCM's listings, but the problem is the size
of the hole in
the cabinet, appx 7" which is slightly smaller than the 8"
speakers listed
(most were around 7.2"). Also this speaker has a very long
throw compared
to most I've seen, I don't know much about the speaker
specifications. This
is a sealed box, probably 2 cu ft volume...
I am hesitant to use a generic speaker in a subwoofer, the
one in it still
works, but distorts at hi volume. I would be afraid a
replacement would not
perform or endure well.

There's a similar thread going on at this list (look for "AR
speakers"). You don't need to get the exact replacement. Of
course, Kenwood is www.kenwood.com
Look at www.partsexpress.com www.matelectronics.com or
www.mcmelectronics.com for other suitable woofers. Parts
Express has the best selection. Just get one with the same
voice coil type (single or dual VC), similar impedance
(Impedance is not that critical with a sub as it is with
mid's or tweeters) and power handling capability. Look for
one with the lowest fs (resonance). Get one that is
recommended for the enclosure type of the current enclosure.
If you don't see that listed: If this is a sealed box
(infinite baffle/acoustic suspension) get one with a low VAS
close as possible to the enclosure volume in cu.ft. If it's
bass reflex (ported) a higher VAS will do. The Qts should be
lower for a sealed box than for a ported box.

Hi group,
This powered subwoofer needs the speaker replaced. I don't
have part number
or contact information for Kenwood. I need to know part
number, price and
where I can get the part or information. Thanks.
