  • Re: SDA 1C vs SDA SRS 2

    Yes they both have vertical tweeters. From what I can see on the photos they are both blade blade I really appreciate all the knowledge here and the fast responses! :smiley:

    If in fact the SDA SRS 2's do have the blade/Blade I.C. they are the 1986 Gen 3 version & IMO less desirable then the later 1987 pin/Blade gen 4 version for two reasons. First - You can not use a AI-1 or Dreadnought I.C. in order to run a non-common ground amp including mono blocks (The crossover design won't allow it). Second - The cost of upgrading a gen 3 crossover, It can be very expensive depending on what caps you chose.

    The 2 versions of the SDA SRS 2

    1986 SDA SRS 2 (Gen 3) w Wood End caps & Black Cloth sides with a Wood stripe, blade/Blade I.C. (It will have 2 binding posts), Dual board crossover, with 2 MW6509 Stereo Drivers, 2 MW6509 Dimensional Drivers, 2 SL2000 Tweeters & a SW150 Passive Radiator.

    1987 SDA SRS 2 (Gen 4) w Wood End caps & Black Cloth sides with a Wood stripe, a pin/Blade I.C. (It will have 4 binding posts), Single board crossover with 2 MW6511 Stereo Drivers, 2 MW6510 Dimensional Drivers, 2 SL2000 Tweeters & a SW155 Passive Radiator.

    Now the SDA 1C, Most people don't realize that there are at least 3 versions of these.

    An very early (1987 i believe) Studio version (Basically a left over SDA 1B cab) with a dual board crossover, with 2 MW65211 Stereo Drivers, 2 MW6510 Dimensional Drivers, 2 SL2000 Tweeters & a SW120 Passive Radiator.

    Now what's interesting is component & value wise the Capacitors, Resistors & Inductors are the same as the the single board pin/Blade crossover. The only way to tell for sure is to pop a driver out and check the model #, if it's a MW6510 or MW6511 they are indeed SDA 1C's but if it is a MW6509 they are SDA 1B's.

    SDA 1C Studio (Black) with a pin/Blade I.C., Single board crossover (BE1618-B) with 2 MW65211 Stereo Drivers, 2 MW6510 Dimensional Drivers, 2 SL2000 Tweeters & a SW120 Passive Radiator.

    SDA 1C w Wood End caps & Black Cloth sides with a pin/Blade I.C., Single board crossover (BE1618-B) with 2 MW65211 Stereo Drivers, 2 MW6510 Dimensional Drivers, 2 SL2000 Tweeters & a SW120 Passive Radiator.

    Either model would be a good be fit for that room. If it was me and the SRS 2's were the pin/Blade 1987 Gen 4 model I would take those if not take the SDA 1C's. Or with that room (25x16) I think I'd hold off & save up my money and go for a pair of SDA SRS 2.3TLs or SDA SRS 1.2TLs (If you have the room "Go Big or Go Home" :wink: )

    Do some more investigation, If you can get a 4th or 5th generation SDA they will serve you better down the road, Remember the 4th or 5th generation SDAs are the only ones that can use the AI-1 or Dreadnought I.C. so they will work with non-common ground amps.

    There's nothing wrong with the earlier SDAs there wonderful speakers just be aware of there limitations amp wise (Common Ground only).

    Don't even get me started on sites like Facebook and the damage they do all in the name of the "Mighty Buck".

    I place them right up there with "Disco" as one of the biggest if not the biggest perversions ever perpetuated upon mankind! :rage:

    We will all "DISAPPEAR TOGETHER"!

    That's true but if Club Polk has to stoop to the lowest common denominator then it should disappear as by then it will at best be like any other forum or worse useless. Club Polk should be better than other audio forums. JMO
