    I found a picture of old 12s that appear to be only in fair shape. The 12" woofer was strictly passive; the open-air crossover on top was massive. The stands were caca and fell apart. They looked much better with the grilles on.

    In those days, the Polk 10's and 12's kicked butt. Actually, the 12" driver is a passive radiator. The movement of the 2 mid bass driver's cause the passive radiator to move. They are only connected acoustically. (no wiring). The cabinet size & dimensions are critical to how it works and extends the bass. It's very efficient so it requires very little power, yet it can handle up to 200 watts. Great design of the day.

    This pair of Polk 12's look pretty beat, especially the 12" passive radiator. The passive radiator should be replaced. I bet it still sounds great.

    Lots of folks really don't understand the complex physics of speakers. Technically a "passive radiator" is a lot more 'active' than a ported design. The advantages that a design that utilizes a PR has over a ported design are numerous -- AE Speakers --- Superb Quality, Unforgettable Performance, Definitely.

    WOW, I hope your kids fully appreciate what you're doing for them. The system you put in your youngest daughter's room is pretty sweet.

    Looks like you're a big fan of Polk speakers.

    I have never owned Polk speakers, but I do own speakers from GoldenEar which is founded by one of Polk's founders, Sandy Gross.

    You should post a thread about your various systems in the Member's System Forum. http://www.hometheaterequipment.com/...s-System-Forum

    Include lots of photos. I love seeing other people's systems.

    The first set of Polks I experienced was the T15's, when I switched out an older pair of Optimus LX5's. LX5's are good bookies and very good as surrounds with that Linaeum tweeter on top. The T15's gave more depth compared to the LX5's, so I kept a pair for one of the bedrooms.
