Bonjour Alan (étant donné votre nom et que vous habitez le Canada, je suppose que vous êtes francophone),
I think for your purposes the PSW111 will do nicely; however I do think that you overpaid for the system you got. The TL350 is just plain pricy and I haven't seen it discounted much. Now, IIUC you are looking for a system composed of 5 small satellites and don't want to make the room for bookies let alone floorstanders; if so, the TL350 or TL250 will certainly fill the bill, but you do pay a premium for the small form factor.
FWIW, I purchased my TL250 from newegg.com two years ago for $320 shipped--and that included a free PSW111. I wound up selling the 8" 150W PSW111 and got the 12" 300W PSW505 instead, which I am currently using in my 7.1.4 living room set-up (FL/R-75t, C-CS2 Sii, SL/R & SBL/R-OWM5, FW-55t, FH-OWM5, TM-80F/X-RT). Like you, I do not want my living room cluttered by or aesthetically overwhelmed by speakers and that criterion has factored into my purchases.
You may well find that you are very happy with what you got, but if you have the room for a somewhat larger SW, the PSW505 is IMHO the best bang for the buck. Newegg is currently selling it for $200, but they sometimes list it for $180 and earlier this week for a short time you could have bought it for as low as $140 (listed for $170 with a $30 VISA checkout discount code). That's quite a bargain in my book! There are certainly better and more powerful subwoofers out there but not for anything approaching $200, and I like the performance and relatively small footprint of the PSW505 which at just over 15"H fits nicely under a side table in the corner of my living room.
You can read a number of newegg user reviews of the PSW111
here and the PSW505
here.
Salut, Jeff
P.S. You could get my used TL250 AND a brand new PSW505 for less than the $500 Crutchfield was asking for the TL250 plus PSW111!
