    I heard some MB Quart towers in 1993 and loved them. They exhibited excellent imaging.

    Great video and great brand. I started out with the Large Advent and went to the BA400s for an upgrade. I was disappointed. The A series were like the Advent, with a big bang for the buck, and pretty accurate with cheap cabinets and crossovers and spring clip wire connectors. But the grills fell short, and the copolymer tweeter was a tad dull. I ended up with ADS and no more foam surround rot, the silk domes tweeter and mid range are dead accurate and can take the dynamics and reproduce the transients perfectly without ringing. Copolymer drivers were created to eliminate paper driver absorption of moisture like humidity and rain that would affect the cone TS parameters. Copolymer is heavier and slower, so the original light paper cones in dry circumstances sound better. Highly suggest going with butyl rubber surrounds and shim the voice coils to avoid scraping in a re-surround. Rich So can fix most speakers and the T/S parameters are improved. Foam degrades gradually so it is in a constant downfall in performance with time. Butyl rubber is constant for 40 plus years. Thanks for the vid,

    I think I had the HD9 from 96 to 2014 and loved them. Not sure if this is the older model bc the ones I had had a metal grill. I did had the HD 7 or 8 and those had the cloth grill. But great sounding speakers. I just saw a pair of HD5 for sale at this random selling store, but looks over 20 years old and don’t want to deal with reforming. But I couldn’t get the cloth grill off and you need something trim to pry off the grill.

    I re-foamed the passive radiators and they sound fantastic. I sold the rest of my stuff. Cheers!@@HighDesNurse
