SDA 2B Owners (have you ever added a pair of CRS+'s to the picture??)

tophatjohnny

Exactly what I'm doing here within the week, so checking to see if anyone's heard them together in the same room, and what did ya think?? Thanks

tophatjohnny

The suspense is killing me, so out on a limb I am going to say this combo will rock the crap outta my bedroom!! Thanks Johnny..."don't mention it, I was new here once myself"!!

You talking about running both pairs at the same time? I am pretty sure that would sound terrible. If you are aiming to "rock the crap outta" stuff. You should look at some big Cerwin-Vega's.

When I first picked up my SDA 2 B's there were 4 pairs fired up at once through a Denon Receuver..no power amp, and they sounded amazing??

You said 'Pretty sure" and my thread is really reaching out to those that have tried it, so your opinion is important to me Gary, it's just more of looking for those that have tried the combo. Rare birds maybe, but this bird will have it up and ruining for an honest listen real soon. I will keep ya posted...in the meantime....anyone??? I mean anyone's that's actually done this??

I had 2 pair of CRS's hooked up on one of my technics interateds they were not directly across from one another one pair front l/r the second pair up against the back wall on the right side of the room, played at a pretty decent levels they sounded just ok playing both pair at a time however the SDA effect sounds better playing one pair at a time. I prefer to play my big ol AR58's or my Vegas when the need comes to shake the foundation. So in my opinion I wouldnt mix your 2Bs and CRS'S into the mix together.

I haven't heard it either, but I know enough to feel comfortable siding with halo on this. It will destroy the SDA effect, but maybe that's not what you're going for? So, tell us what your goal is....?

It will sound like crap. Let me translate; neither pair will sound as intended. Now, if you like things to sound differently than they were painstakingly designed to, then of course that's your right.

Plus a receiver won't power one pair of SDA's properly, so running 2 at the same time, why bother.

I know I am hearing things as the Onkyo sr805 is making te SDA 2 B's sitting here sing like angels, and I was also hearing things when I was over at member's house (mansion) members name (favner) while he was powering up 4 pairs of the SDA 2 B;s with his denon high end receiver, and there again, the sound was unbelievable?? Reading is one thing, but again, I'm looking hear from those that have done this, not those that have read about it???? Thanks H9.

All I can say is " you ain't heard nothing yet". I have heard SDA's powered by receivers and they don't hold a candle to a proper amp and pre-amp set-up, not even close.

I have also heard 4 SDA's running in stereo and it sounded like crap to me, compared to a properly set-up single pair running off quality seperates. So until you experience that all you have to go on is what you are hearing now.

If it floats your boat, that's great, but don't try an convince those of us who know better that it's all that..........because it's really not. Also remember you asked the question, don't ask the questions if you aren't happy with the responses

Have fun, enjoy.

I'm not sure if this intended for me, but what makes you think I was basing my opinion on reading about it? I sold SDA's back in the 80's and 90's when they were new. Have several friends that owned them back then. I own them now and I can assure you my opinion is based solidly on experience, not reading about it.

Don't really understand what you're trying to achieve with that kind of setup in a "bedroom"? Does that bedroom have theater seating? Because when I do run my SDA 2Bs I do so in a 10' x 20' space and you really don't need anything more than those in that space.

Now if your bedroom dwarfs my basement room, then do what you wish. But you'd probably be better off just getting bigger SDAs and more power for them if all you want is Bigger Bad A$$ sound?

Thanks for all the great feedback, and will report in on my take when I get the CRS+'s added to the picture. Hope to floats my boat. The bedroom is a big one, 18"wide x30+' long, bed in is the middle of it a;; and TV/stereo is directly across from the bed! Not a huge master. BR but good size. Bigger than the living room here! lol I'll try different positions with the CRS+'s so this might be fun. Hey. if all else fails, I'll stay with which one sounds better then sell the other pair!! Right??

Hey Johnny,I have talked to myself here also.I say try them out see what you think, if it doesn't work find another room.Maybe a kitchen or shop set up.You can never have to many speakers ask Audio Alan.

Agreed; I've been there done that with 2 pair of sda's running in the same room. It doesn't take long to forget all about the "wow" factor and realize that it does in fact sound like ****.

So, towards the end of this thread I asked a similar question, and whamo....I was told that they are a perfect match for my SDA 2 B's. Was even offered a pair for a mere (650 dollars?? ) I appreciate that but a little rich for my blood!! Just depends on who you talk to. From here on in, I'll listen with my ears, not my eyes!! :razz:

nspindel

The 2B and the CRS+ are virtually the same speaker. From a sonic signature standpoint, yes they are a perfect "match". However.... I don't understand why you would want to do this. SDA is a very particular application. Two speakers sit side by side in front of you, with one speaker pushing out a phase-inverted mirror image of the other's signal, thus the reason for the interconnect. The stereo driver is towards the outer edge of the speaker, and the dimensional driver is towards the inside edge of the speaker, which is why there is a discreet left and right speaker with SDA's.

SDA technology simply does not work with speaker position other than dead in front of you. I'm assuming you are putting one pair in front of you, and the other on the sides. SDA's as side speakers simply do not make sense. And if you're going to set up the four speakers in front of you, you'll have the stereo driver of one mixed with the dimensional driver of the other, it just doesn't make sense. If you're looking to make your 2B's sound bigger/better, then go up the SDA flag pole, check out some 1C's or even bigger. But if you read Matthew Polk's white paper on the science behind SDA, hopefully you'll understand why doing what you're describing simply does not make sense.

I've owned multiple pairs of SDA's in my life, including 2B's and two pair of CRS+'s, and have used nothing other than SDA's for the past 23 years. Trust me when I tell you this is not a good idea.

Johnny I was referring more to comb filtering and a smeared SDA effect running them both at the same time. But hey, try and see. If you like it life is good again right.

tophatjohnny

Perfect match in one thread, and explanation in another. Cool!! Thanks, Still may have to try it and see how it works on these old ears!! Will lool cool that's for sure!!:razz:

halo71

Hell if looking cool is what your after. Go buy 2 pairs of 1.2's and stack 'em!

nspindel

2B uses SL2000 tweeter, MW6510 stereo driver, MW6511 dimensional driver. CRS+ uses SL2000 tweeter, MW6510 stereo driver, MW6511 dimensional driver. So from that respect, they are a match. But why you want to do this I don't understand. But it's your ears and your money.
