    can anyone name this connection? Sorry Ben, I lost you trying to send you this pic.

    I understand the distaste for Sony but the specs on this amp are not bad...

    Currently there is a Sony TA N80ES Power Amp for sale on AUDIOGON for less than $500 and here are some of the amazing specs of this vintage Sony Power Amp that has a variable attentuated input option which can eliminate the need to use a Preamp for the Audio Purist and it can be run in Stereo or bridged into a very powerful Monoblock-

    2x 270W (4Ohm, 20Hz...20kHz, THD 0,006%)
    2x 230W (6Ohm, 20Hz...20kHz, THD0,005%)
    2x 200W (8Ohm, 20Hz...20kHz, THD 0,004%)

    1x 610W (8Ohm, mono,20Hz...20kHz, THD 0,004%)

    So if you're looking for a Power Amp that can deliver real world high wattage thruought the entire Audio Spectrum and not just test well on the bench at 1k hz like so many modern Receivers are spec'd then the TA N80ES may be just what you need.

    I cant PM. I only have 8 posts. Sure I would love for you to come down. I've been talking with Ben and he is helping me spec out some of the right stuff so I can get away from my "Ghetto" Setup. Let me pick up a HK AVR and maybe an adcom amp and get the furniture in here this weekend and you can come over anytime!

    You might consider this one .... It is a touch light on the watts but it is a very under-rated amp.

    That is a very nice amp and it will make the SDA's sing, Not too light for the SDA's.

    Those specs aren't great at all. Only 70 extra watts of output from 8 down to 4 ohms? A good amp will come close to doubling it's output from 8 to 4 ohms so it should be 200wpc @ 8 ohms and 400wpc at 4 ohms. Some middle of the road amps will do 50% or more.

    Get yourself a serious amp if you want to really use the SRS's as intended.

    Those specs are pretty bad.

    Thanks Heiney9. I'll take your advice. I was thinking an Adcom with a HK AVR reciever with pre outs. Do you have a suggestion?

    By a used amp for now. You have a long road ahead with mods and such before a real nice amp will do you justice.

    I'm usually to impatient to start slow but your right... I'll look for a nicer HT reciever and a little better amp. Thanks for all your help. I'm sure I'll have more dumb questions along the way. I love these speakers!

    Thanks again,

    Guys,

    I took a very good listen today to the tweeters on the SRS's and found that I really have one good one on the right channel with three barely putting out audio and two good on the left channel with the other two barely putting out audio. Is part of this the SDA? I thought the SDA only affected the drivers and not the tweeters? Or is it a combination of both blown tweeters and the SDA?

    Thanks again in advance,

    David

    Sounds like you bought a defective pair of SDA's. I'll take them crappy speakers off you hands free of charge.

    Leroy,

    You just might have to. I might be too dumb to own them... Even with the "defective" tweeters and my "ghetto" setup (reciever/headphonejack/pre-amp) connected to a crappy Sony T N80ES... They sound f-ing great! I can't wait to see what they will do with a real setup.

    So... If I may ask. How would I test the tweeters to see if they are functioning?

    Why do some of the tweeters put out more sound than the others in the same cabinet?

    The tweeters are a tapered array. One of the tweets will put out most of the sound. The others will assist with a little reinforcement. I prefer a single tweeter in my builds, but this puts a lot of stress on them. I have a big pile of burnt tweeters to prove this.

    Yes, it's part of the design and is referred to as a "progressive point source". The Sda comes from the outer drivers in the array and does NOT include the tweeters in the stereo dimensional array.

    Thanks H9. I purchased some material to recover the grills and the sides (Thanks DK) and I was wondering what success other people have had with attaching the fabric. I repaired some sections with hot glue and I like the fact that it dries quick but should I be using something else?

    I have to integrate it with my HT so I was talking to Ben and he suggested an Adcom amp and maybe an HK AVR with the pre outs. I've been looking at those and hoping to stumble across something on cl in the meanwhile. My wife did just get used to the shock that I was actually keeping these so I'm laying low for a few days... :)

    noosh, I like those 1c's but these SRS's need some tweaks and I need to learn. Hey, When are you coming down? I need all the help I can get.

    I've been playing with the placement of the SRS's as suggested by Ben. Specifically working on the 3 feet on the left. Moving everything to the right I can squeeze about 2' 4" out of the left with the placement of about 5' 8" apart from inside to inside, 6" out from the wall.

    This seems to be the best listening configuration but once the furniture arrives it will cause everything to look too far to the right. When I move the left speaker closer to the wall (about a foot away) it lessens the SDA effect but gives me a better, tighter bass.

    I was thinking about getting a new smaller cabinet to store my components. I'll still need to shift everything back to the left a little but I was thinking a smaller cabinet would help. What do you guys think?

    Thanks,
