Well, listen: the driver unit on the SS-2s are 70 (seventy!!!) mm in diameter!
Description
The Sansui SS-2 is a moving coil type headphone with excellent transient stability from 20 to 18,000 Hz, top L/R balance characteristics and a high damping factor.
It utilizes specially developed cone paper with high radiation characteristics for exceptional low frequency reproduction.
Distortion at 1 mW is less than 1%; output sound pressure is lower than 1 dB.
Completely adjustable and softly finished in vinyl-chloride for wearing comfort.
With a 3-phase voltage plug, the SS-2 can be used with amplifiers of varying wattages.

!!!!! That might explain why it's like M. Tyson punches me in my ears when listening very extraordinarily loud.
(But I'm not trusting all those specs due to the fact that all other places I've read about the SANSUI'es SS-2s the writer claims they're from 1968. Unbelievable FLOWER POWER iow. The max input on the very loudly K550/553 Professinals are 300mW. That's only 60% of what these beasts by SANSUI & most likely my EE-45s by "who knows" can handle. And an Impedance @ 8 Ohm I'm not wondering anymore why they are loud (but the building quality of the drivers etc. etc. just have to be quite adequate to handle such insane loud pressure). I love the fact that nobody in the entire Cosmos would've paid more than $10 for my Eastern European fugazis. After ordering some ss-2
s from SANSUI I'll listen to my fakes one of the head-fi set'ups in this flat (DacMagic+, Argon HA-2, Argon HA-2 - QED and Tara Labs Interconnects). Can't hardly wait
I'm gonna purchase 2-3 pairs of the originals and tweak one of the pairs to the max (almost).
