Did a search but no joy. Perhaps I expressed the string incorrectly? Can someone distinguish the two for me? Are the differences visually identifiable? Any consensus about which is preferable?

    Check this link provided by nadams to me to answer some of my questions.

    http://clubpolk.polkaudio.com/service/models/modelpartslist.php3?model=monitor

    Basically there will be tweeter differences, I don't know if there are also crossover differences but I would assume so. The 7's of the Monitor Series are favored here pretty well.

    Welcome to the Club, Cort...

    The Original 7's sported the Peerless tweeter and are most sought after for that reason. Very well behaved tweeter.

    Thanks for the info. The ones I'm looking at have the Peerless. BTW, I'm in Dallas and found this through Russ.

    Besides the SDAs, my Monitor 7As are by far my favorite Polk that I've had the opportunity to own or hear. Yes, mine have the Peerless tweeter. They just seem to do everything right when hooked up to my tube pre and tube amps. They'll likely never leave the house and are in about as good a shape as a 29 year old speaker, that has been listened to, could be.

    I'm anxious to snag these--they're local. I, too, want them for tubes.

    Had to get a pair after I'd heard that they were superior to the 10's. So I got a pair with peerless with the rosewood vinyl wrap. Speakers felt really light, too light. Listened to them for a few months and just couldn't get over the lack of bass, they seemed to roll of sharply on the bottom end and I couldn't get over the lack of foundation with the bass drums and bass. The seal was good and I even stuffed some acousta-stuf in there to see if I could get more bass out of them. Finally gave up and pulled the damn near perfect peerless tweets, the brand new polk drivers that I bought to replace the broken ones that they came with, the passives, the crossovers and polyfill and tossed the crappy cabinets into the garbage. I wonder if the crossover was to blame. If not, and that's how they all sound ... no thanks, I'll stick with the 10's or better yet the RTA 12B's.

    MY monitor 7B's with the Peerless tweeter are the most sought after of all the 7's. :rolleyes: :p

    JK if you can find a pair of original 7's. buy em. Don't dismiss the 7B's though w/peerless tweeter.

    Strange to say the least. Did the 7's have less bass then your monitor 5's? My 7's have good bass for their size.. i don't expect them to produce the same amount of bass as say the 10's or other larger speakers.. but i'm using mine in my HT without a sub. and bass is ok. not great. but decent for their size.

    Danger,

    They sounded more extended than the 5's, but too faint down low to keep me groovin'. They should have held their own in a two-channel setup with that passive 10". I don't know man, just couldn't deal with 'em. I'll try another pair some day down the road.

    There had to be an issue somewhere. Maybe placement or the room or something, because my 7As have more bass than one would expect from a speaker of this size. The bass is also tight and accurate. :)

    While the 7's have sufficient bass, they are not the 10's equal by that measure.

    What the 7's do bring to the table that the 10's cannot match is imaging.

    Sorry to read L&C dismantled a pair.
