    Just got them from Nuera.
    http://www.nuera-acoustic.ca/products/W23-973s-3.jpg[​IMG] [​IMG]
    I will get MLSSA going today and see how the 926 goes against the 871.
    Will post the findings in a few days.
    I posted this yesterday on PE and of coarse # 1 sin
    for me not to talk about non PE product on there site.
    As per norm.
    45 reviews of the same post in 25 minutes and it was pulled.

    Hence I will not review the TB products PE is getting and could careless.

    Ya i agree.
    All these new drivers with a pin frame.
    Not all that easy for the DIY to mount.
    And the 2X3 will be plain nuts to mount.

    TruckBedLiner, you have been a bad boy[​IMG]
    I clicked on the link and all that popped up was a small picture of the little black driver only - no specs.
    Are driver mfgrs stuck in a rut of designing frames that are the traditional car configuration? They must have tooling they've invested in and hasn't worn out yet.

    You can only view the photo on Nuera's site.

    I love it! It's just like the hyperlinks that say "click here for a larger view" and all it does is open the same picture in a new window. [​IMG]

    So Allen,

    Any update on these? I'm thinking of building a set of small speakers for a friend, but wanted your impression of the new drivers before I ordered some more 871's.

    Well, the 926 looks smoother. Does it sound smoother?

    Sound very clean smooth not sharp.

    Detailed but not bright.
    Over all not bad.
    I let this driver play fullrange for 5 days before I posted a measurment.

    The off axis I will get to in a few days as well as a side by side with the 871.

    OK spec.
    Same cabinet volume as the tested i did on all the 3" drivers.
    Round over on the inside of the cabinet of 1/2"
    Ported same as other drivers I tested.

    I did these as then all the tests were the same volume same port hole, same filling.
    Mic was placed 24" from the center 4 feet off the ground.
    For those that missed them here is the others I did almost a 6 months ago or more.

    They look pretty good, but how do the numbers compare for in room response? Are they worth the hassle of the non-round flange compared to the 871s? It appears they roll off a little higher than the 871s, but don't have that 200hz hump.

    They need to sound a good bit better to compensate for routing that stupid pincushion frame profile. TB, listen to us: Round driver frames only - please!

    What group are they marketing towards? Can't be DIY with that design, can it? Are there manufacturers in Asia building with them?

    I will say they have made the pin frames for Norh as a OEM and more OEm than you can think of.And once a new design comes out who more to put it on than the DIY.
    But yes,my thought same as yours.
    That is what I said about the 593S that was made to the 871 when I placed the order for them in the first place.And looky at the 871NOW.
    This new driver round frame with XBL.
    Now we are talking?????????

    Ok here are the new drivers.
    The new 2X3.
    As well as the new 926.
    Mounting .You must use a 2 15/16" hole no larger.
    Then a hand rasp or a 1/16round over bit to radius the hole.
    If you look at the picture you will see in the phot with the 926 on top side view the lip under the pin frame.
    If no radius is done the frame sticks up.
    Radius to much you have a air leak .
    Sealing them I used SILICONE.
    a small amount under the driver frame put on the radius after i got the driver to sit flat.

    As i said in the other post mounted in the same cabinet volume and tested same as other tests on 3" drivers.
    In all not bad to mound just a EYE sore to look at that frame.
    But in time I will make somethink.
    Sound against the 871.
    First I will say metal to soft dome.That in all almost sums it in easy terms.

    I will get more info on them in a week or so.
    Off for cabinets that must be made.

    Alan,

    I stopped using silicone when I found the miracle of closed cell rubber tape. the kind used for windows and doors. Its sticky and fits the mounting ring of most woofers perfect. Its comes in 1/4" and 1/2" not sure if comes smaller. Plus I'm a slop with silicone:b I can use it fine...I always just end up wearing it.

    Sorry for the noobish question, but what does the "cumulative spectral decay" plot show and what should one look for in this?

    You mentioned the box is the same for all of the other speakers, but what are the details of the box?

    Shawn.
    I have and only use closed cell tape.
    But as the photos show you will have no change in the world of using anything but silicone or any liquid sealant to get in the area of the frame on the following drivers.
    W3-593S
    W3-594S
    W3-926S.
    Or the Frame will stick up in the air.
    The liquid is used as it takes very little space and does just what it is needed to.
    Seal, and stop frame vibration the best it can with out added mass to the frame.
    Look at the pics and you will see.
    No way to get any tape to work.
