Anyone on here own a set of NHT 3.3 or 2.9 with the foam for anti diffraction rotted or falling off? If so I have found a method of cutting foam that looks and sounds stock and is easy to replace. I can send you some of the ones I have for free. You must be a current member though. Pics.

    I never realized those came with foam anti diffraction strips.

    You did an excellent job making those, that stuff isn't easy to cut and make it look good.

    Thanks, mine did not look that bad but was rotten anyway. I took the grill off one day and my finger caught it and a big chunk was gone. So I took it off and thought, it cant make that much difference. it did. I tried some weather stripping that was close but really didn't sound like it did. I made a metal template to the exact size and clamped it down on a plastic cutting board making it almost flat then used a rotary razor cutter.

    Ah, so that's how to do it. Thanks.

    I actually used a piece of MDF at first but switched after the first two.P1030494_zps2o17qx1y.jpg

    Did you make the metal template or have someone make it?

    Cool technique.

    I have a little pair of NHTs (1.3a) in my bedroom setup that I've been enjoying for several years. They didn't have the anti-diffraction foam, however; that came with the 1.5 and its larger brethren. Always have had a jonesing for the 2.9/3.3, but there's zero chance they'd work in my house.

    I made it out of some 1/4" sheet bronze, it was pretty easy.

    Thanks, These were the one speaker my wife kind of objected to because of the depth. We actually re-arranged the living room to accommodate them easier. But I tried them in my 2 channel room and liked them better there. They can be a pain to set up and picky on associated equipment but when you get it all dialed in they really shine.

    Rotary knife on compressed foam! Nice job. Cutting foam rubber with a sliding knife blade is difficult even with a new blade.

    Hey "Doss". I left a message in your mailbox asking if you are still doing the foams. I obtained a pair of 2.9's recently with the foam rotted off. If you are still doing them, I would be proud to remunerate you for a pair. Thx

    Hi Doss -- same here for me. I need a pair of these foam diffraction strips. If you're still doing them, please let me know. Thanks very much. I'm located in Pittsburgh.

    Hello
    Zardoss
    Looks like you could make yourself a nice little cottage industry with the diffraction foam stripes
    There are plenty of happy NHT 3.3 owners out there with rotting foam stripes that are in need of your services..( as am i). If you are still making them I'm happy to pay for them with of course shipping
    thanks so much
