((With the half a dozen different amps I own and various comparisons in real SPL's:
I would say that the manufacturer's specs are actually conservative and that sensitivity is at very least 88db regardless of what stereophile tabloids might publish. It is in their interest and the interests of other advertisers in their publications to diminish what Vandersteen has been able to produce and offer at such a low price!! I use my 2Ci's as a reference regardless of what else I might own. For the price, there is nothing comparable!))
Amen
I brought home many different amps over years to drive
2Ci,CE and Sig 2s most all of them had a picnic driving these speakers to enjoyable levels.
Whats confusing to the meter readers is Box speakers with baffles will reflect their unwanted reflection artifacts as a higher SPL number.
Because the Vandersteens are a baffle less multiple enclosure design, they possess less unwanted reflection firing back on them and then into the SPL measuring Microphone
Also why they disappear so well.
