The Mortite Mod, a cheap tweak but is it worth it?

Obviously this poll is for those who actually tried this.
Sounds good to me...

    Moretite (or similar) helps damp resonance on certain ill-behaved cast metal horns...

    I also used it to damp the frame of Radio Shack 40-1354 5-1/4" fullrange twincone drivers. Not sure it actually helped, but it couldn't hurt. These have also had Dave Dlugos' (www.planetsofta.com) phase plugs. Enclosures were designed by Bob Brines (Brines Acoustics) and built by my woodworker/contractor friend Mike Berg. I was actually listening to these last night after a fairly long hiatus; they sound very, very good - single drivers cannot be beaten for imaging (albeit with a fairly narrow window).

    Can't vote here...have a box sitting in my office and a set of Monitor 5s that need sealing but have been too lazy to break out the old screwdriver and get the job done. So I'll have to report back. But I'm pretty sure it's going to be 'worth it' because they are not properly sealed at this point!

    Is there an easy way to tell if they are not properly sealed?

    I have to say it was worth it for me. Did a pair of SDA 1.2 TL's, some SDA 2A's and some Monitor 5jr's and it helped all of them

    Are your gaskets damaged? If not, you should have a good seal.

    Mortite is a fine tweak for anyone wanting to spend some time with their speakers, but it wasn't a night and day upgrade for me. I will however be redoing my friend's Infinity RS 4.5s with Mortite as his current driver seals are all but disintegrated.

    As mentioned above, I've tried it for dampening before, but it's not worth your time.

    I haven't pulled the speakers out. I'm just going by the numerous posts here that say mortiting really improves the bass response.

    I did notice a very small improvement (so I answered yes), but vastly superior to the mortite are Larry's rings.

    The rings made a night and day difference in the sound.

    My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

    I found otherwise.

    I think the "positive" results that some have are due to the fact that the screws had loosened over the years. Of course, in applying the Mortite, the screws get tightened up. Therefore, I suggest tightening all the screws first.

    I too did not notice any difference with the mortite either.Waste of time IMO.

    I liked the results on the vintage polk drivers with stamped steel baskets. I wouldn't bother with any cast basket drivers. Yes I did tighten all the screws on my drivers and had no air leaks.

    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    I found there to be a HUGE improvement after applying Mortite. It definitely wasn't due to the screws being loose, as F1 alluded to above. All of my drivers had been checked for tightness multiple times before I ever applied Mortite to them. My gaskets were in fine shape too, as far as I could tell.

    Bass output was vastly improved, overall midrange clarity was much better...the midrange seemed to come more forward in the mix, and blended with the highs and lows much better. This mod is an absolute no-brainer IMO. I'll never own another pair of vintage Polks without Mortiting them.


    Jesse-Have you ever tried Mortiting your speakers? I seem to recall you mentioning a while back that you just didn't feel it was necessary, so you never tried it.

    I seem to recall that using Mortite was actually a Polk Audio suggested tweak too.

    I know I'm probably out of line here,but I can't help but wonder what's up with the red letter title under CC's name? A time-out maybe?

    Sorry for the derail,back to Mortite

    Curt was mistakenly "banned" for a short period. It was an error by the mods as I believe he quoted a spammers post and somehow was automatically banned when the spammer was banned.

    Brings up a good point, using Mortite without flattening it out one needs to be careful when reinstalling the screws. If done carefully and tightened diagonally there should be no issue.

    Sometime before the end of the month I'll be putting Larry's rings in my 5B's so that will be documented as well as the listening observations. Only real problem is I have a new computer with new sound card option's (USB) so I need to become familiar with the new system before making a change like this or my observations will be skewed.
