SDA 2A Receiver Question
Freeridesnomore
Posts: 17
I am looking to buy a nice receiver for these speakers or a nice power amp and receiver setup. I am looking at possibly a pioneer sc 71 by itself or a marantz 1603 and a adcom 555 paired together.I mainly want bluetooth capability. What are your thoughts? I dont have the interconnect cable for these speakers but I may find one at a later time.

I powered my SDA2b's with a 555 & it sounded very nice. It was with a 565 preamp. Havent heard those receivers so i cant comment. Read good things about Pioneer & Marantz's. Yes you will want the IC cord so their doing what their ment to do. Welcome to Polk also..

What are your thoughts?
You need the SDA cable now, not later.Political Correctness'.........defined

Very few receivers will handle the 2As. They're 4ohm, and drop well below that at certain frequencies.
The Adcom 555 combo would be a much better choice. I believe it's common ground, but best to check with the manufacturer.
As F1 noted, get the interconnect cable now. You can purchase a replacement blade/blade cable from Polk, or better yet, replace the blade/blade sockets with SpeakON connectors, and make your own with some quality speaker cable, and SpeakOn Plugs.
Without the cable, the 2As are operating in stereo only, and will not be a true test of the load your amplifier must be able to handle.Home Theater/2 Channel:

The Adcom GFA-555, as well as the GFA-555II, is definitely a common ground amp. There's lots of folks around here using them with their SDAs.

Currently running SDA 1c's off a Adcom 555 and a Dared pre-amp. Good combo

I ended up getting a Pioneer sc 61 AVR it has the bluetooth deal coming with it so i got part of what i wanted I done some research on it and found that people are having luck with it and 4 ohm speakers. When my stepfather used them he had an old sansui receiver thing was a monster not sure of the specs but i do remember the tweeters dropping out from time to time when playing real guitar music with the research I have done on the speakers I am guessing its the safety built into the crossover. I also read after the safety trips a few times the thing is bound to trip more often. If this receiver doesnt do the trick it does have alot of pre outs built into it so i will always have the option for the power amp. The other problem with the avr is I am not sure if its common ground I am guessing its not and i wont be able to use the interconnect cable but i would really like too. Cant have everything you want in one package I guess. I grew up with these speakers somewhat so they are special to me so i will do whatever it takes to get them singing again. Thanks for your replys gentlemen.

Good to hear you're wanting to get these speakers singing.
First of all, you NEED to get the interconnect cable working. That's the whole point of the speaker.
Second, go easy on the volume knob at first and don't overdo it.
Third, under $400 could get you a decent used amp. You're right it does have pre-outs so that is a good thing.

Since nobody mentioned it, you have to get that interconnect cable asap.

Newbie here and sorry to hijack - I just acquired a pair of 3.1TLs. I know I need more amp, but for now wondering if they are safe to test with my Pioneer VSX-523 or Technics SA-AX530. (Hooking up just one speaker at a time?)
I'll test with a multimeter but should I assume they are both common ground?
If neither is common ground, is it still safe to test just one speaker hooked up at a time to one channel with nothing on the other channel?
Thanks,
Ryan

If you don't hook up the cable it doesn't matter, if it's common or not, so you could hook up both. If you don't hook up the cable your listening to 1/2 a speaker. Most modern receivers are common ground.POLK SDA 2.3 TLS BOUGHT NEW IN 1990, Gimpod/Sonic Caps/Mills RDO-198

ALL, I repeat ALL 2 channel receivers or AVR's are common ground.

Fantastic, thank you both very much. I will be fabbing my own interconnect cable (from what I understand, it's a simple pin-to-pin for the signal and then a spade-to-spade for the ground) for sure, this is just basically to make sure the speakers are functional in my short window to reject them as defective. my 3.1TLs

Do NOT make a connection to the blades or bad juju will happen. Only the pins carry the signal with the standard SDA cable.Political Correctness'.........defined

Yep I did some reading and managed to figure at least that much out.
Anyway ... no sound from either tweeter. From what I gather, no polyswitches in the 3.1's. No continuity across the voice coils. Previous owner must have fried them. Mid / bass sounds muddy but I'm assuming that's a result of my low power amp, have seen that mentioned on here before.
Going to check out the voice coils, if it's a no-go, it'll be time to order those upgrades. my 3.1TLs

Without the tweeters playing the rest will sound like mud.Political Correctness'.........defined

Two blown SL3000s - open voice coils. Not sure where the breaks are. And ... ferrofluid! Just like the Vifas I'm familiar with. I wonder if anyone sells just the diaphragms for the SL3000s.

Back up to guy who got the Pioneer avr. It's still an avr and just about everyone here who runs avrs w/ pre -outs eventually gets an independent amp to handle the load and makes the avr your pre/amp. You've been told way many times already you need to get the i/c or your just wasting space and not using the speakers to their potential. Even an with amp you still need the cable so make them or get it first then see how it sounds.I tried it and eventually went for an Adcom 555 which seems to be both popular here, very inexpensive for 200 wpc and they are all over the place for around $300. You want those to sing,rock or even on mellow music there is a difference that will make you smile once you get the cable and amp. As Tony B says " do not go cheap on I/Cs. Brands have been thrown around here thousands of times.2chl- Adcom GFA- 555-Onkyo P-3150v pre/amp- JVC-QL-A200 tt- Denon 1940 ci cdp- Adcom GFS-6 -Modded '87 SDA 2Bs - Dynamat Ext.- BH-5- X-Overs VR-3, RDO-194 tweeters, Larry's Rings, Speakon/Neutrik I/C- Cherry stain tops Advent Maestros,Ohm model E

To my surprise when i went to get the speakers today he had the original cable too. I checked the Pioneer avr and it was common ground. Sounds better for sure with it hooked up. It sounds like there are more speakers in the room. And that is very cool.
Hooked em up with 12 gauge wire from the local audio store. The AVR handles the 2a's well I am happy for now with what I have. Thanks guys for the chat this is a very cool forum. -
Congrats on your new AVR & speakers. Nice receiver BTW. I would do some research before hooking other speakers to that AVR while using those speakers. They may drop in ohms & it may overdue the AVR. Maybe adding a amp for just the fronts down the road before adding others to the mix will be ok. Got some nice stuff there & hate to see smoke/damage. Just a thought. Enjoy ..

Thought id share a couple pics of the rough setup I havent tidy everything up yet I just wanted to hear everything haha.

Interesting. Those look kinda like 2b studio's. Whats very interesting is they look alike. Are the 2A's older version ? What are they Blade/Blade ?..

Yeah, Randy, designers/manufacturers rarely design/make a B model prior to an A model!
...sorry, couldn't help myself.
Looks like a nice pair of 2As, Freeridesnomore. Keep us posted on if you do decide to add an external amp into the chain and what your impressions are.
