Polk SDA's

[Toolfan66]

Can one of you polk SDA guru's tell me if all SDA's are 4 ohm's?

Thanks,

Larry.

Which ones? Some are some aren't. They typically have a nominal impedance of 4 or 6 ohms depending on the model. SDA's dip as low as 2 ohms and up to like 64 ohms......all dependent on the musical signal. Regardless of ohm rating because of the interconnect it does tend to put extra stress on the negative side of an amplifier. Weak amps need not apply.

[Toolfan66]

There is a pair of SDA-1A's, and a pair of SDA-2's here in town, i am ready to look at a pair of starter SDA's for a 2 channel set up, and i want to start with the speakers first.

Thanks,

Larry.

I believe the original SDA 1s were 4 or 5 ohm nominal. SDA 2s were 6 ohm. What heiney said...they aren't that hard to drive at reasonable levels, but do like the current.

[Toolfan66]

Well i picked up the SDA 2's during lunch for $150.00 need a little TLC and a new tweeter, but i will just change both of them. the cloth is in great shape.

And i need the interconnect cable. Anybody know where i can get one?
if i remember polk no longer makes them right?

Thanks,

Larry.

Pics or it didn't happen. :D

Yeah, I have been asking around for the cable too. Blade/Blade or Blade/Pin?

Ben can make you one. Nice snag.

You can make your own. The Blade is just for support. For now use a piece of stranded wire wrapped tight....just jam it in the "pin" hole until you can make something more permanent. Some use an RCA end with the collar clipped off....exposing just the "pin" portion. Mine are converted to a Cardas banana plug connector, with banana's on each end of the cable.

Those are a few different options

which model of SDA 2's did you get?

[Face]

If they're Pin/Blade, I would assume 2B's.

Tool(I feel funny calling you that :D), did you order the tweeter yet? If not, look into the TL conversion.

[danger boy]

I on the other hand have no problem calling someone a Tool :p ;)

Can I do this with my SDA 2A? What is TL conversion? Lol.

[Toolfan66]

I was in a hurry when i picked these up as i was on my lunch break i just glanced at them put them in the car. they are SDA 2, and they do have Blade/Blade.

Her are some pics. one tweeter was changed to a Boston, Looks very cheap, and one side was off. But over all not bad. A little TLC, and i will have them looking like new.

Where do i look into the TL conversion? I have not ordered the tweeters yet they are just the SDA 2's.

Thanks.

I saw these posted last nite... congrats on the purchase and have fun restoring them. I did my 1c's and they were about the same shape when I got them.

here they are now...

NICE PAD!! Did you upgrade the caps as well?

I have been debating on driving down to the springs for the SDA-1A's as well.

[nooshinjohn]

:oI did not upgrade them yet. Only did the rdo's and cosmetics so far. Whenever or if Ben decides to speak to me again I wanted to sent out my crossovers to him. Not a great time to ask now though:o

[zarrdoss]

Not bad Sda 2b's these are just like the one I sold Discjockey, An easy trick for the tops and bottoms is Black Bison furniture wax, alot easier and cheaper than stain and clear.
This thread has links to find the blade blade ends or someone on here could make you one Im sure.

Thanks, i figured this could be my starting point in refurbing some speakers.

[nooshinjohn]

they are not to bad to work with and the sense of accomplishment when you set them up for the first time... priceless!

[Conradicles]

I have the exact same model in my 2-channel rig. Blade/Blade cables can still be purchased from Polk. I bought one.

Congrats on the SDA's.

Just note that they are very , very sensitive to room placement and distances. Sound can change a bunch by just moving them inches.

Agreed, Plus it's not like i am out anything here, if anything i saved a pair of polk SDA's, and if i ever sell them as i move forward in this hobby somebody will have a nice set to start with as well. or i just move them to the garage for tunes.

How do you like them? and what are you using to power them? i have been debating on adcom or rotel.

SDA's in the garage is an offense punishable by death in 27 states and life in prison with a bose wave radio in the rest so you best rethink the garage part:p

[zarrdoss]

If you need any hands on assistance let me know, PM me your e-mail and I will send you a PDF of the manual for your speakers

HAHA ok i get it:D

[zarrdoss]

the manual has some detailed info on setup

[Conradicles]

How do you like them? and what are you using to power them? i have been debating on adcom or rotel.

I have tried about 4 different ways to power them, but please keep in mind that I have not near as much experience with these as many folks here. Here is what I have tried so far:

Yamaha receiver = O.K. but I do not like Yamaha
Audiosouce AMP300 = O.K. but I like the 300 better in my HT rig.
harman kardon 3480 = Very nice IMHO...perfect low budget match for smaller SDA's
NAD 317 = Very nice and is my current rig. Only rated 80 watts per channel but way powerful enough for me.

George and others rave about the tube amps with the 2B's, but I have not tried that yet.

And the manual is actually very informative unlike some others I have seen.
