@beetlemania , those are random peaks into a load that doesn't drop below 4 Ohms. My amp is capable of 500 Watts per channel continuous into 4 Ohms and double that for up to a couple of minutes. All within Thiel's recommendation.

  @casecadesphil,  As you may well know as a loudspeakers impedance drops so respectively does it's sensitivity. The 400 Watts into 2 Ohms previously suggested is similar to 100 Watts into 8 Ohms. 100 Watts is the minimum Thiel recommended for the...

@cascadesphil, but how much power are these amps delivering into 2 Ohms and at what levels of distortion?    
Old Vandersteen model 2 vs. newer model 2
IME, the Vandy 2's are particularly critical of placement, more so than most other speakers. On the other hand, they are very accommodating with regard to amplification.  
Thiel Owners
@bobscliff, the CS 2.4's impedance drops to below 3 Ohms. You're not likely to find many amps spec'd to the 2.4's specific minimum impedance. One might find some amps spec'd to 2 Ohms. If you want to get what that the 2.4's are capable of you'll w...

@sjbellers, the "Thiel Bass Equalizer" is intended to compensate for the natural bass roll off of the speaker enclosure by boosting the those frequencies affected by such roll off via equalized amplification to restore the bass extension that woul... 
I wonder what you would think if we scheduled a monthly Zoom Meeting?
Count me out.

@tomthiel, I was suggesting that if the Benchmark’s are capable of delivering power into lower impedances that they rate their amplifiers into such impedances with what ever distortion level they choose so long as it doesn’t exceed 1%.. If the dis...

@tomthiel, While Benchmark’s class leading distortion specs are truly impressive, their use of non-standard standards is curious. One has wonder if the difference between the vanishing low distortion measurement standards of the Benchmark compared...

@tomthiel, the impedance limits of an amp depends on the speakers attached to it. Most later floor mounted Thiels from the 1.7's / 2.3's / 3.6's / 5's / 6's / 7's have a  minimum power recommendation of 100 Watts per channel into 8 Ohms. The nomin...

^The Benchmark amps are at the very top when it comes to a lack of distortion within their load tolerance. They are also somewhat special in that their input allows for a variability that is somewhat uniquely accommodating for system matching.  Re... 
Concentric drivers
The most recent Thiel concentric drivers use a rippled cone area to offer additional strength that allows for flat profile to mitigate the doppler affect that would otherwise be introduced.  
Thiel Owners
@Thieliste, it depends on the model Thiels, room, desired volume levels and the particular amplifiers in question. While Class A has advantages with regard to cross-over distortions over Class AB, there’s more to good sound than that alone. Furthe...

^I too have often (perhaps too often) gone on record record here on my strong preference for sealed boxes, not only for bass output, but for overall coherence as well.

@thosb,: Thiel CS2.3 Loudspeaker Specifications | Stereophile.com Thiel CS2.3 Loudspeaker Measurements | Stereophile.com Thiel's recommended power for the CS 2.3's was between 100 and 400 Watts per channel for an amplifiers standard 8 Ohm rated...
