    IIRC, he states on his site that his boards are not compatible with the SDA SRS.

    Where does it state that?

    I thought it was on his site, but I haven't looked in a very long time. I now see that it isn't. I guess he figured since the SDA SRS model isn't listed that would be enough.

    I see also...in order to upgrade to TL in addition to the crossovers, one would have to change the dimensional array mids to 6511's along with the SL3000's.

    Right one can take 1.2 to the tl but SRS would be VERY COST PROHIBITIVE ;)
    Plus if i remember correctly the actual cabinets are made from different materials.

    I agree, think I'll be keeping mine stock and just upgrading the crossover and internal wiring. different material on cabinets...hmm

    the Rondo series is awesome for internal wiring. It is tin plated (cant oxidize), super flexible, good gauge (13 awg) and a high quality product.

    Sounds like you're talking about "marine grade" wire. Tinned and annealed.
    All kinds of gauges available here;

    This I'm guessing would be just the ticket for speakers, 25' of 14ga duplex, $12.

    Is there a board suitable for the SDA SRS and SDA 1B from gimpod? I don't see either the SDS SRS or SDA 1B listed.

    I'm also trying to figure out what parts I need to buy for both the SDA SRS and SDA 1B.

    Sorry. Was half asleep. I meant do the values of the parts and schematic of the Vr3 and gimpod mods deviate from the factory and if so what are they?

    I'm trying to figure out what parts I need from Clarity Cap ESA, Clarity Cap PX, Mundorf Mox Resistors, Jantzen Inductors.

    So far I don't see anything that is the same in Clarity Cap ESA.

    Example:: I need a 92uf 75v 10% (factory) but don't see anything in the PX or ESA line of Clarity.

    The closest is a 100uf or 82uf px from madisound. If I stick with factory which in this case I'm assuming I don't need any inductors.

    These are the parts in the crossover minus the inductors. Can anyone tell me the upgraded alternatives including (if required) new inductors, I should use and does anyone have a PCB layout I can use for the lager components?

    Was the PCB board schematic the same as factory in that thread?

    can Butyl Seal Tape be used in place of "DynaMat" on the Stereo and Dimensional Array (SRS) to attenuate "speaker basket" ringing? Thanks for any help!

    Nice work. I hope to start some upgrades to my 2.3tl's soon.

    well, it took me 6 years to get it done, but I am nearly finished with all the upgrades. Thanks V3R for all you did, and thanks to the forum for the info, details, and suggestions. These upgrades work! They sound much better than they did when new, and they sounded great new. They sound amazing now.

    I nominate this modification as an upgrade and predict it will become a staple here...
