Monitor 11T Question

in Speakers
So yesterday I bought a pair of these older speakers for super cheap. The guy selling them said he had them for about a year, and got them from his coworker. They had some cobwebs, which I wiped off. In the few hours of listening to them (as fronts) they sound a little weak. They don't produce as much bass at my RTi8s, and none of the woofers appear damaged (sound comes from all of them, and I can push them in and they immediately pop back in place). I know not everyone doesn't think/believe that speakers require a break-in period, however, could these have been sitting unused for quite a while and need just some time?

    After a capacitor sits unused for years it looses some capacity. It will regain some back during a second "break in" so it might sound a little better letting the speakers play for a while. But your problem is the caps are approaching their useful life and were not very good to begin with. Do some searches here on rebuilding the crossovers.

    Sounds like a cabinet leak.

    Thank you all for your responses! We watched another movie tonight and they sounded better overall, except one of the radiators or woofers would sound awful during a bass-heavy scene. So now there's that!

    Push down gently on one of the drivers and the woofer should move out. It should stay there for 5+ seconds (the longer the better). If the woofer comes out then quickly starts to go back in you have a leak. There are a lot of posts on this so do a search here to find out how to fix it.

    So I figured out what was causing the awful noise. The bottom radiator completely pushes in at high enough volumes (and during certain scenes). It happens on both of the speakers. I assume they need to be replaced? And both of the tweeters make a hissing sound. Should I replace/upgrade those as well? Thank you all for your help and responses!

    Sounds like you are driving your amp/AVR to clipping.

    I don't believe I'm clipping anything, and I can push the bottom radiator all of the way in without using much finger pressure.
