    2268HPL Question

    I have a 2268HPL which I purchased in need of a recone. I do not see listed on the JBL site T/S for this driver, but they list the cone as the same as the 2268H. That would indicate to me that it should perform identically to that driver? Is it possible to recone this as a G, or are there variations in the magnet structure that would make that unwise? Or even more interesting to me would be reconing as a 2269G.
    Any insight would be appreciated, especially from Giskard,
    Thanks

    Evening, Harry,

    Though I'm certainly not an expert, I asked something similar the other day. I have a 2242HPL, and asked is there was a difference between that and the 2242H? I was told that the one I had came without the "tire" on the ferrite magnet, hence the slightly different designation. Your driver may well be the same story. Hopefully, one in the know will come along soon, and either support that thought, or not. I'm thinking it might be right, however, based upon my own experience. Take care, and God Bless!

    Every Good Wish,
    Doc

    Recone

    Out of curiosity: How come the 2268HPL is in need of a recone? It can't be more than 4 years old.

    I did not get a story, but I am assuming overexcursion due to abuse. the VC is locked up, and moves only reluctantly.
    There is no tire, but I do not think they have a tire for the Neo drivers?

    2268hpl

    Talked to the nice folks over@JBL today, an Everett Watts who explained that yes the HPL is the no rubber tire model, and it is an H really and could be reconed as a "G" but JBL wouldn't do it(Policy) and did not recommend reconing as an FF, but gave no rationale(but I did not ask either).

    Harry,

    The "FF" version is the dual voice coil model which is used in the VRX918SP, so it is not interchangeable with the other two. But the H and G (or HPL and GPL, 8 ohm and 4 ohm respectively) kits are interchangeable.

    Any source to look at the differences between 268 (new Eon sub) and 2268?
    Thanks

    All of the above discussed speakers are dual coils and the FF is a 2 ohm coil.

    This is incorrect. The H/HPL and G/GPL are single coil, and the FF is dual coil. The FF is 2 ohm per coil though, as said.

    I will look at the links provided but heres the real deal.

    I just looked at the links and all the speakers are listed as differential drive technology.(Dual coil)

    Hope this helps.

    All of the Differential drive motors have two coils with a braking coil between. That's the basic configuration of the DD motors. Normally these two coils are connected and are not independent.

    I think we just have a difference in terminology. Yes, there are two voice coils on the former on the H and G. However, as Rob said, they are not independent of each other. While the FF model is a true "dual voice coil" design with 2 separate terminals (+ and - for each) on the speaker. In my original post, this is what I was referring to.

    Take care,
    Eric

    Quagmire of terminology

    I see your point Eric.

    There is reference to dual coil in both the 2268FF and the 2268G devices description in the JBL links that you provided.

    So JBL refers to both devices as dual coil.

    Perhaps a clearer terminology of the independently wound and individually terminated 2268 FF should be considered.

    I guess we both learned something new today.

    And so now, where do we turn to get the skinny on the 268G, 2268, adn the 2269?
