Hi, I have what was a rather expensive component set (retailed at around $800 cad back in 2011) that I am not using and I am considering using to build a set of hifi home speakers for a 2.1 application. I will power them with a Marantz 1060 in a small room for low to moderate level listening.

My question is: Will these woofers sound any good in a sealed or ported enclosure? If so what would be the best enclosure for them?
Or will they only sound good in an open baffle application, being designed for car audio.
Thanks for any advice.

Given the Qt, either a really big sealed box, an infinite baffle, or an open baffle.

If you're OK with hacking on some drywall, you could also try them in-wall (assuming you have typical stud walls and an open cavity).
Insulation for stuffing, lots of it, will really lower the Q if you don’t have the option for large cabinets
And if that is not enuff a hole with lots of stuffing until aperiodic. Tune for flattest impedance.

'Best' depends on the needs of the app, so for HIFI my preference using just published specs would be ~ 20*8.2*0.74^3.3) = ~ 60.72 L vented TLs (MLTL/MLTQWT) tuned to ~ (0.42*68*0.74^-0.96) = ~38 Hz and stuffed to 'taste'* by using the above 'click' test or at least as a baseline if not happy with it for whatever reason.
* the driver/box combo only loads to its upper mass corner (Fhm) = 2*68/0.74 = ~184 Hz, but the XO point is way up at 2.5 kHz, so in trying to get a well damped 'in situ' bass response without over damping the 300 - 2 kHz critical mids can be a tedious, time consuming affair if room treatment isn't used.

Open baffle mid&top over a small sealed bass woofer?
Something like

XO about 240hz to 300Hz

Every time I have attempted to leave the back of a driver exposed, too much of the back wave enters the listening area.
Myself, would probably just use an average sized box, can do as Dave mentioned and make a tuneable panel or something similar where you have a series of 3/8” holes to use as a vent. Those holes would be in two 1/4” panels of plywood, using insulation compressed between them.
That will give you a controlled leak to help get the optimum response. And also use a lot of insulation inside the box also. What I mean by that is an amount that makes you wonder how any air can get around inside.
