Bought these speakers off Ebay for $45 brand new -- the owner had a spare pair, he did open them up for testing. They came looking brand new and no scratches. However hooking them up, they do not remind me of any Advent sound/speaker that I have listened too. With the Advents I listened to in the pass, they tended to be somewhat muddy/boomy or somewhat bright sounding.
The reality is, this is Audiovox playing on, marketing on the Advent name. Audiovox sourced these speakers for Heco, the German speaker company they also owned. They are known as the Heco Krypton 200 in Europe. They have a 5.25 inch woofer and 1 inch dome tweeter -- 11" h x 6.75" w x 10.5" d -- cabinet 5/8" thick and weigh about 10 lbs each
The sound is more on the linear side -- and they have good off axis response. Off axis is more linear than on axis. The somewhat rising treble is not really colored. The bass is there and musical, and about 5 hz shy of the Canton. The sound is clean with no excess sibilance, congestion, or nasal sound. They also throw a nice dimensional soundstage with some good central imaging and separation. The imaging is a little better than the Canton GLS. They for sure are better than the former boomy, and lacking in detail Polk RTi4, and are better than the Sony Core.
The crossover has 11 parts, a hint not of Advent. They were designed for the tweeter to be below the woofer. The cheesy part is the grill and the thin grill pegs. I broke one of the grill pegs. Audiovox did not market them well in the USA. Plus the front of the speakers tend to have more of a HTIB look. However, I can live with the looks a little more than the JBL Studio 5 series.
