I found the Pioneer TS-SW3002S4 new for $59 on ebay, so basically the same price. (8% off coupon right now too)
The QTS is higher on the MB Quart is .696 (.7 and above is generally considered okay for infinite baffle application) (= good for this application), and the FS is lower on the MB Quart which is seemingly better in this application too. The mounting depth on the MBQuart is 3.07 vs. 3.4 - so it's a little shallower too which is good for my application. The Pioneer takes twice the power in modeling at 10hz, but that's largely inconsequential if the excursion limits are roughly the same. I'd just set the iNuke voltage limiter a bit lower on the MB Quart. The Pioneer has a little stronger motor structure, and a heck of a lot more moving mass -- which
stated to be of high importance. The Pioneer appear to be a completely enclosed basket, which might be nice the thwart any unwelcome fall season house mice.
I've been out of the car audio subwoofer game long enough I don't know who has a better reputation these days, or more importantly the potentially more honest/accurate specifications (Pioneer or MB Quart). Back in the day I thought MB Quart was a higher end brand, but that's 20 years ago since my car audio days, and I don't know if that still holds any truth.
hmmmm, is this half dozen of one and 6 of the other? Or is there a real victor here for this one off, in chair application. I'm not looking for any sound, just more of the low end shake - like
showed me on his BOSS platforms that were good down to 3-4Hz with plenty of it. That's hard to feel on a basement concrete slab absent very high SPL, and even then - simply not as much felt as Sheldon's BOSS platform. I'll probably put a steep ~30hz LPF on this setup. I don't like higher frequency vibration if my previous experience with more traditional tactile transducers, and near field subs is of any relevance.
For those of you who aren't familiar with the subwoofer driver parameters, or just needed a refresher on a few of the acronyms, these links are helpful.

I could potentially buy one of each to compare, before buying the other three I suppose.
There's also a relatively inexpensive Infinity shallow subwoofer driver for ~$75, but while the Fs is lower than the MB Quart or Pioneer, the
BL is too, and so it doesn't appear to be as suited for infinite baffle, and probably not a good choice over the cheaper MB Quart or JBL - assuming all specs are reasonably accurate. Most of the other name brand shallow subwoofer driver options quickly approach >$100 per driver and so make an inexpensive impulse purchase project -- less of one...
