SDA2B v 1C?

Should have put the 2B's on the more powerful amp. That said, the 2B's modded to TL's with crossover upgrades are hands down the better speaker to my ears.Political Correctness'.........defined

I have to agree!! -

Thanks F1. For what it's worth, when I swap these two amps on my KEF 104/2s, I cannot tell the difference at all. Neither speaker seemed to be needing more power here, but I'll give it a try sometime soon.
For now, in stock trim, I like them both, but the 1C is my favorite.
Curious, with mods to the xover, how would this help improve bass response and make up for what appears to be an advantage in sheer number of woofers to help displace the low frequency demand? Our friend TNRabbit turned me on to a great test track that separates the real speakers from the posers, Bela Fleck's Flight of the Cosmic Hippo - 1Cs did it well (not up to my Carver ALiiis) but the 2Cs were't even competing.
I continue to learn daily from this forum, thanks much for feeding me! -
Take a twenty year old car and put in a new motor, transmission, and rear end with new tires.
Get where I'm going?
Mods to the crossovers will push them to 125mph with ease.. -

You'll notice a difference with SDA's.Curious, with mods to the xover, how would this help improve bass response and make up for what appears to be an advantage in sheer number of woofers to help displace the low frequency demand?

The -3dB rating for the 1C's is 35Hz, the 2B's are 38Hz. What you hearing with the 1C's is a pumped up mid-bass.
I know at least one CP member that sold his 1C's after modding his 2B's to TL's. I heard both, the 2BTL's with the RD0198-1 sounded better and produced plenty of low bass.Political Correctness'.........defined

Yep, I get the concept of the crossover mods. But starting with 2 similar speaker models, both being SDA design, one having a seemingly clear advantage by sheer number of drivers, why wouldn't the 1C benefit more from the same type of mods? if the 2B went to 125, why wouldn't the 1C redline further?
I don't get where you're going in this light yet, thanks. -

Cool, thanks, maybe keeping both for the time being. Anyone want a set of KEFs:) -

TL'ing is also a key point, and I don't believe the 2B's the OP is auditioning are TL'd.
Last, modding the large inductors on the 2B will give you whatever anyone might have imagined was lacking in the low bass register.VTL ST50 w/mods / RCA6L6GC / TlfnknECC801S

For the record, I'm not knocking the 1C's, they are a fine speaker and I'm sure some would prefer them. Subjective hobby after all.Political Correctness'.........defined

Were the 2BTL's you heard on stock inductors? -

An hour later, we were bringing these speakers to my house.
Couple of beers and some down and dirty side by sides against the SDA 2Bs and here are my impressions:
1Cs powered by McIntosh MC2205 (205 watts rms); 2Bs powered by 2105 (105 watts rms), otherwise, all other electronics sources equal; both are stock unmodified speakers representing the last of the series; both had the factory SDA cables installed. Neither appeared to be straining or needing more power, so I think the amps were not an issue here. Listened mostly to CDs through my Linn Karik player and a few albums on the Rega P2.
We put the speakers side by side and pulled them out in the room. Not ideal as it would have been better to lay one set face down when not using and they were a good few feet out from rear and side walls as they need to be and were square/perpendicular, no toe in. 1Cs were on the outside, 2Bs on the inside. I could quickly switch off one set and turn on the next.
2Bs are brighter on top, much to my surprise with only 1 tweeter. They didn't have as much bass down low by comparison. Alone they sounded great, but when compared to the 1Cs for bass, you noticed what was missing. Excellent soundstage and imaging. They definitely sing nicely.
1Cs were more balanced in the high end. Where I turned the 2Bs flat on treble, one click positive on the Mc C28 was nice for these. The 1Cs definitely have more bass, not overpowering, but what was lacking in the 2Bs was there for you to hear and feel. I was not surprised at all with 4 woofers v 2 feeding the passive radiator. Imaging and soundstage was really amazing on these. We both felt they were just easier to listen to.
So, the winner here is the 1C v 2B in the SDA stock shootout.
I've also put some carpet piercing cones underneath the 1Cs today and the bass really tightened up. Very happy with the SDA sound!
Wish I had more posts to list my 2Bs as I'd love someone here to own them.
I'm about an hour south of Indy off I-65. 10 minutes from Louisville.
PM me some details on the SDA 2B's and I'll likely take them off your hands...

I've heard the 1c's stock, and also after putting in one pair of rdo194's but they still had one pair stock.
I heard my crs+ stock of course, then with rdo194's, then modded crossovers with the rdo198's. I absolutely love the rdo198's, but the rdo194's are good too.
It's a close call on your dilemma. You can pretty much do all the same upgrades on the 1c with the exception of rdo198's. The guys here have heard probably all the different variations, so I would take their advice as being very good advice on what you will hear after modding.Polk Audio SDA CRS+ crossover 4.1TL by Trey/VR3 (Rings and custom stand by Larry)-Polk Audio SDA SRS2 crossovers by Trey/VR3Parasound HCA1500aYamaha rxa-3070 with musicast-Celestion SL6S presence,- sl9 surround backNHTsuper1's surroundMagnepan SMGParasound 1500pre- Sofia "Baby" tube amp - Monitor Audio Silver RX2 Marantz 2230/B&Kst140Technics 1200mk2 Gamertag: IslandBerserker I am but a infinitesimally small point meeting the line of infinity in the SDA universe -
