    LE14H-1 and LE14H-3 pics

    Since I was swapping the new LE14H-3 drivers in my $303 PS1400s with the LE14H-1 drivers in the PT150 boxes, I pulled out my iPhone and snapped a few photos. It was a pain in the butt without an assistant, so there are no prize winning photos here, but maybe someone will find them useful or at least interesting.

    From the front

    LE14H-1 on the top, LE14H-3 on the bottom. Notice the differences in the frames. The-1 is flat, has a flat paint finish, and has bolt holes that accommodate beveled flat Philips head bolts. The -3 has a thicker, beveled frame with a crinkled finish and bolt holes that are meant for machined bolts with round shoulders and thick Allen heads.

    A closer look

    Hmm, maybe the -1 has a satin finish??? Whatever.

    You can see the rubber surround on the -3 (on the right) vs. the foam surround on the -1. The -1 also has the ring around the outside of the driver; the -3 does not.

    Driver depth

    The frame diameter is the same, and the bolt mounting locations are identical. They fit and mount in the same diameter baffle cut out.

    From the side, though, differences are evident. The -3 is on the left, and it's intended to be mounted such that the thick front part of the frame is flush with the baffle, which requires the driver to be inset rather than riding on the baffle like the -1 does. Also, the frame is heavier, with additional reinforcement.

    Since I'm not inclined to change the L250 cabinets in case I return them to original condition, there is no routered inset, so the -3 drivers rest on the baffle, too. Thus that thick front frame results in the cone and surround being slightly further out that the original -1 would be.

    From the rear

    These shots were a pain. Since the drivers are heavy and unwieldy, I had to hold them up with one hand and try to focus and shoot with the other. I could have laid them down or leaned them against something, but I was not willing to risk scuffing a surround for this impromptu pictorial. So, this is what I got.

    The main points of the shots are 1) to show the additional castings on the -3 frame on the right and 2) to show they still have foilcals on the backs.

    Connectors

    A clear difference is in the speaker wire connectors. I find the -3 connectors on the right picture much easier to use and more firm in their connections, especially when you only get enough wire in the cabinet to connect the drivers while holding them near the opening with one hand and inserting the wires with the other.

    When installed mine I had to the longer screws. I didn't compare the 2. At this time I hooked I think 3 different 250 2 with 1 and 1 with 3 , ran through a velodyne SMS as a subwoofer and got 3 vey different results, my 250s are not consitant sounding . Different x overs , rebuilt ,some charge coupled w tibq ...they just aren't right so I am not good example to use
    Changing to Legacy Audio and started with a Silver Screen HD for my center between the 250TIs

    I`m really happy now!!

    Yes, that was fast! I thought that maybe before christmas or something, they would arrive, but suddenly I got mails - telling me that christmas came early this year!.

    So now there is rubbersmell all over the house. Wow they do look good!!

    I have to wait a little bit, before I can mount them. My friend in Stavanger, who works with PA - audio (he was the engineer of the famous norwegian band: Kaizers orchestra, if you heard about them), comes home. When I have new projects, he often assists me. The last time I changed the woofers was in 2002 and I did it alone. This time I want to do it properly - lay the speakers gently down, and then gently assist the woofers into place. And also do some cleaning and dusting before putting it all back together.....

    Am I excited!!?? yes!!

    So what do you members think I should do..?

    I`ve been thinking, and thinking for at least a couple of years now, I`m living in Norway, and I`m dedicated to the 250ti Limited edition sound! How many other speakers I`ve listened to, I don`t know, but there`s nothing that even comes Close......

    The last time I changed the woofers, was in 2001. The LE14H-1 has functioned very well these 14 years!!! But now - I can see that a change is indeed needee!!
    Should I go for LE14H-3!!?? Will I be satisfied? Will the bolts and mounting go well? Any dramatic change in deep bass or Dynamics?

    If this goes well - I will have stretched the Lifetime of these beauties for several years.

    I think the 1st page of this tread answers any questions about mounting. Sonically there shouldn't be any difference.

    Not sure how this applies to the LE14-3, but here was Greg's reply from another thread on the 250 towers:
    Quote Originally Posted by gtimbers View Post

The LE 14-3 has a rubber surround which doesn't wear out. Although it uses a thicker frame, it will mount into the enclosure. The grille may or may not fit, however. The problem with this substitution is that the -1 woofer is about 1 dB lower in sensitivity. The LE 14H-4 is too loud by a dB.
    ". . . as you have no doubt noticed, no one told the 4345 that it can't work correctly so it does anyway."—Greg Timbers

    Ok.

    Thanks! I see...and I who ran through the local hardware stores, in order to find the right screws, before the woofers would arrive...

    I cross my fingers, and hope the LE14H-1 woofers will survive the NeXT 49 weeks.....
