  1. Polk SDA II speakers   $375

    Matched pair of high end Polk speakers. Truly amazing sound.

    The SDA series was Polk’s first attempt at expanding the state of the art in loudspeakers. The SDA-2 was just below the top of the line SDA-1, which added an extra mid-woofer, a larger cabinet and a few hundred dollars to the price, along with slightly more bass extension. The SDA-2 is no slouch and many over they years felt it superior to its big brother.

    SDA stands for Stereo Dimensional Array, and its goal is much the same as what Bob Carver was after with his Sonic Holography: to cancel the aural crosstalk which smears the imaging clues and confuses the ear. In the Polk version, an umbilical cord connects the left and right speakers and feeds the left channel signal to the right speaker’s SDA array and vice versa. This has the effect of canceling the crosstalk, making the left ear hear the left speaker only and the right ear the right speaker only (in theory). In practice, it is far more effective than one might think.

    The SDA-2 speakers are mirror-imaged pairs, with the driver compliment as follows: two 1″ soft dome tweeters horizontally arrayed near the top of the front baffle; below the tweeters are a pair of mid-woofers, also horizontally arrayed. On each speaker the inner tweeter and mid-woofer are the SDA drivers; the outer pair work conventionally. Below the two horizontal arrays is another mid-woofer in line with the outer woofer above it, and below that is a 12″ diameter passive radiator, which takes the place of a conventional port. A black cloth grill covers all of the drivers. On the back panel, there is a tweeter-protection fuse above the single set of 5-way binding posts. Below the fuse is a socket for the umbilical cord connecting each speaker.

    Model: SDA 2
    Tweeter: 2 x SL1000
    Stereo Driver: 1 x MW6600x
    Bass Driver: 1 x MW6600x
    SDA Driver: 1 x MW6600x
    Bass Radiator: SW120
    Crossover: Dual Board
    SDA I.C.: blade/Blade
    Dimensions: 12"D x 16"W x 39-1/2"H

    Sensitivity: 92 dB / w / m Nominal Impedance: 4 ohms 
    Suggested Amplification: 10-500 watts continuous;common ground amplifiers only

  2. Posting some pics now of a few of these along with a better description.

     

    Cerwin Vega Hed U321 Speakers - $300

    These Cerwin Vegas are a hard to find HED design with extremely high output and crisp, clear sound. I bought these from an estate sale and did significant restoration. The tweeters are brand new and the exact same model as the original tweeter since they were still available to purchase new. The classic red foam Cerwin Vega woofers are no longer available for purchase new. I did extensive research on various drivers and used the Thiele-Small parameters to find the woofer to give optimum performance from this enclosure. The woofer I selected gives solid performance down to 30 Hertz and in my opinion sounds better than the original Cerwin Vega woofers. They are polypropylene with a foam surround which is the same style the original Cerwin Vegas used.SHOW LESS

  3. I have quite a few speakers that I am trying to sell. I will bring as many as needed to the pilgrimage if anyone is interested. For now these include:

     

    '85 LaScala

    Polk SRS II

    Cerwin Vega HED U321

    Pioneer CS R70

    Sterling SE 300 Cathedral

    AudioSource LS TWO

    Infinity SM112

    Factor Electronics 70v outdoor model

    Frazier cabinet/bookshelf speaker

    B52 club/DJ speakers with 15" woofer

    Black non branded 8" 3 way that sound surprisingly good

     

     

    If interested message me.

     

    Here is a shot of all the speakers staged and ready to listen to in my garage.  I have an 8-way speaker selector that allows me to pick a single speaker at a time to quickly switch between different pairs of speakers.

     

    The Keurig is for sale too by the way! :)

  4. I have a pair of LaScalas that I need to sell.  I WISH I could keep them, but I'd have to build another wing to my house to have room for them.  It would be perfectly fine to me if I had huge LaScalas in the main living room, but my wife has mentioned words like "aesthetics", "tasteful", "matching room decor" that are completely foreign to me when it comes to getting the best sound in each room of the house.  She told me that I have free reign in the media room but the other rooms of the house she has to approve.  I won the battle in getting to keep my Chorus in the bedroom, but she actually prefers the tower Klipsch F1s in the living room because they LOOK better.  

     

    I have an industrial LaScala (black) for my center channel and I just picked up a pair of industrial LaScalas that I can use for my L/R so they match better.  Alas that means that my other LaScalas need to find another home.  

     

    I bought these from the original owner less than a year ago.  I barely had a chance to use them so I hope they find a good home.  I'm asking $1400 and have them listed in a couple of places but if anyone here on the forum is interested I'll consider dropping that price a bit.

     

    I know these pics aren't the best but I wanted to get something up here to start the conversation.  I'll post more later that show all the side plus the serial numbers.

  5. 1) I have a pair of Polk SDA-SRS II's that I am no longer using.

    2) Plus a pair of Cerwin Vega HED 321 with a non CV-12" woofer, but I did mounds of research and found a driver that gives -3db at 30hz in that cabinet - almost an identical match to the original driver.  

     

  6. I have a pair of Heresy HIPs that I'm selling. I was asking $800 and a local guy offered me $600 cash.  I was thinking about it when he mentioned that he had a SINGLE LaScala pro version that he would trade?  Is this a good trade to do straight up?  I have a pair of LaScalas I'm going to use as my main L/R in my theater (which I haven't set up yet).  I also have a single Heresy I that I had planned to use as my center channel.  The thought of having matched L/C/R LaScalas is very tempting.  

     

    Should I take the cash or the LaScala?  If I take the LaScala, what can I do with the single Heresy?

  7. I sent Roy the drawing and never got a response.  I had to get a quote turned in so I ended up going with the TOA HS1200WT.  I wanted to go with something Klipsch, but I didn't get a response back from Roy and I've never used the speakers I was thinking about personally so I was hesitant to use them in a design.

     

    The comparison between the TOA and the CA-800-T was very close in almost all aspects.  Compared to the CA-800-T which has a 90°x90° dispersion pattern, the TOA was limited to 40° vertical.  For my use this was good because we wanted to keep sound away from the stage and the limited vertical dispersion would help limit any sound coming back to the stage. The TOA has higher power handling if we decided to use it at 8 ohms instead of 70v.

     

    The client hasn't approved it yet - it's a school so it could take months for them to review.

    Yes, these are HIP's and mighty fine speakers! It would help to know which drivers are actually inside, might want to remove the back covers and take pictures. I know there are a few different sets of drivers used in this model, I've seen the standard, single phase plug k-55v with the push pin connectors, the dual phase plug soldered connector k-55v's, I've seen the k-55m's and even the k-52's. Also, the early models had the k-42 EV (Electro-Voice,) which is more desirable than the later k-42 Eminence driver.

     

    Also, I've never heard of the AA-H crossover, is that the same as the HIE?

     

    Anyway, good luck with your sale!

    I edited the crossover type - it was the HIE.  I copied / pasted the specs from something I found on the internet.

     

    It is the K42-E driver.  Pics attached.

  9. I talked to the auction house and the shipping cost would be quite extensive.  Plus, THEY wouldn't pack and ship them - I would have to send someone else over to do it.  I knew a guy in the area who was about an hour drive from the auction location but even if he picked them up I still had the problem of shipping them to Texas.

     

    I'm glad that someone else in this group ended up with them.  Given the unknown resale value I was hesitant to put up too much money for these.  I was interested in the Spendor s8e as well, but I had the same problem with shipping these also.

    Thanks for the comment and request. I'll open them up later this evening and take a look at the exact drivers and post pictures.

  11. I've read posts here on this forum claiming that the HIPs are the best sounding Heresy ever made.  This is the original Heresy HIP with the black textured finish.  Sound is great, the finish needs a bit of touch-up paint, but nothing that can't be fixed with some paint.  I recently bought some LaScalas and don't have anything left to play these on or a room where I could set them up. I really don't want to sell them because they sound FANTASTIC - just not as good as the LaScalas.  My wife says I have the speakers I want in the media room (LaScalas) and bedroom (Chorus), but the living room is forced to use a lesser speaker that doesn't sound as good because the looks blend into the decor better.  As great as these sound, "blending in" aesthetically is not one of the strong attributes of these.  Asking $700 for the pair.  Located in Dallas area.

    Specs:
    Frequency Response: 90 - 17,000 +-5 db
    Maximum Input Power: 125 watts

    Drivers:
    Woofer: Klipsch 12" K-42
    Mid: Klipsch K-55V on K-700 horn
    Tweeter: Klipsch K-77 horn tweeter

    Crossover: Type HIE (edit - corrected from my original copy/paste of specs I found on the internet)

    Dimensions: 21 3/8"H x 15 1/2" W x 13 1/8" D
    Weight: 54 lbs

  12. I have a chance to get a pair of Sequerra NFM-PRO speakers.  There is also a larger set of Sequerra speakers that appear to be a "Signature" model.  Are these decent?  Worth buying with the purpose of reselling?  I don't know if I would have room for the large ones in my listening room.  I'd have a space for the small ones of course.

    I'd only use that amp with the subs it was designed for due to the integrated filters.

    I thought the filters could be bypassed.  I've never used this amp so I'm not sure.

     

    In the spec sheet it said " The crossover can be bypassed to feed the amplifier directly from the subwoofer output of an A/V preamplifier, processor, or receiver."

    If I found one of these amps used at a decent price I'd like to try it in my theater.  I'm using a QSC pro amp in bridged mono for my sub currently.

    Little update on the JBL's...

    Had my audio bud come over last night that knows a lot about active x-overs. He bought one over last night and we got the JBL's pumping....  We didn't have all the cables to get the Crown hooked up. So we used a Carver PM 1.5 for the horns and a Carver TFM-42 to drive the bass bins...

    Over all I was really happy with the sound they put out.... It really was on another level.... But My bud Ryan told me once I get a better x-over then we can hear what those JBL's can do... We quickly found out that those four 15" woofers in those bass bins ate up all the power that Carver TFM-42 had..... we didn't clip the amp, but you could tell they wanted more power... We might have been putting 2/3 watts to the horns..

    So the x-over I'm looking at is DBX driverack PA2.... He was telling me this x-over can do a lot for the money...

    Think I'm going to order this Monday.....

     

    Even my wife was blown away by the sound these monsters put out.... So far really happy with the JBL's.... I got a lot to learn:D

     

    MKP :-)

     

    I have one of those I could sell you.  Nothing wrong with it - took it out of a system where they had upgraded to a larger unit.  If you haven't bought it yet send me a message.

    That looks like a nice amp.  It looks to be discontinued, but i'll keep my eyes open for one.  I've stalled with my project, still trying to select a projector and screen.  Meanwhile I'm loving my speakers.  I had my first angry neighbor the other night, I forgot I had a window open. !! lol

     

    Why do you say it's discontinued?  From the Klipsch website it doesn't say anything about that and lists a price along with availability.

  16. I bought a paid of LaScalas recently from the original owner who purchased them in the mid 70s.  The cabinets were in good shape but even causal listening told me that something was off with the tweeters.  I am going to need to get new diaphragms, rebuild parts of the crossover or both.  I have a pro AV company and I have a QSC CX168 laying around and a Biamp Nexia DSP.  Rather than rebuilding the crossovers I was thinking about bypassing the stock crossover and using the Nexia as a crossover. I could bridge a few of the channels on the QSC amp so I could drive the woofer with a bridged channel (260w @ 8 ohm) and the mid and high each get 90w @ 8 ohm.  The 8 channel amp would give me 2 channels at 260w and 4 channels at 90w.

     

    Using the Nexia would allow me to pick any value as the crossover point, any slope and have full phase control as well.  What are the group's thoughts about doing this?  Has anyone does this before?  What are the potential drawbacks that I might not be thinking about?
