as these speakers break in, they are simply impossible to criticize for the price. to my ear, they offer a surprisingly clear, robust and balanced sound within their 65-20K range. there is of course a degree of opacity compared to my current speakers (vintage hartley monitors with crossoverless midbass driver and upgraded tweeters/tweeter crossovers), but i attribut this to several factors, not the least of which are they are 1) brand new and 2) most surely have bargain basement chinese crossover components (and i guess drivers, but they are not the weak link IMHO). to boot, my current (and incredibly modest) system is currently running a lower echelon (and unworthy of mention) vintage amp while my primary (also vintage but much higher quality) amp is being completely overhauled and updated by audiogon member ezekiel.
the midbass driver looks to be a simple paper-cone-yet-fairly-long-throw deal with treated cloth surround, and the tweeter is some type of polymer 0.5" dome. they are (contrary to the RS website) 10.5 by 7.4 by 6.6 inches and weigh a whopping 5.25 pounds each. 8 ohms impedance with 50 watts nominal and 100 watts maximum power handling. bass reflex design with a small rear port.
to look at them they make me think of something along the lines of a black vinyl clad, chinese linn kan. after a week or so of break-in, my tentative plans are (depending on the degree of improvement experienced) to consider upgrading the crossover components, internal wiring and binding posts, and maybe putting some dampening material on the (likely stamped) woofer basket. all told, still less than $100 per pair and a helluva lot of fun for my money, come what may.
