    Sub-woofer #4

    I purchased a pair of 136H's with fresh re-cones in October finally got around to cutting some wood on the cabinets. Nothing special just another B 380 clone to add a second sub to the LFE channel. Should help with the more challenging movies.

    Is the 136h a 2226 with a different cone more suitable for deeper bass? If so, how does it differ from the sub1500?

    Older version of the 2230's series I think. Used in L300's etc.

    Based off the 2226 basket?

    I have a feeling they will be ALNICO's. The cones are probably the same spec as the 2235 which fits into the 2225 frame but not the 2226.

    Rob should respond, but the "H" suffix would be ferrite, the recent recone
    -likely- means it's now a 2235H (cone/coil/mass-ring/spider).

    Definitely -not- a 2226 derivative. SUB1500 being a completely different animal.

    flash can significantly exaggerate small color shifts.

    http://www.audioheritage.org/vbullet...ilding-a-136HS

    used in the synthesis 15" sub:
    http://www.jblsynthesis.com/ProductD....aspx?prdid=39

    recone kit model number is C8R136
    quite confusing...

    S = shielded (as in the magnetic field is shielded from interfering with CRT video screens)?

    I thinks its S as in Synthesis
    Those systems are made to be used in home theaters with video projectors, so I guess a shilded subwoofer is not really needed

    I think if you want to get a 2235 that close to a CRT you are going to have more problems with the CRT falling apart than with colour problems.

    Grumpy is spot on they are essentially 2235's with the fresh re-cones. They came out of a pair of junker L300's that were parted out. Got the cabinet together now I have to add some Delta-dB dampening compound to help stifen the box up. It's neat stuff and easy to use. Just trovel it in and brush it around.
