@atmasphere , not to mention that mine are 8 feet tall which means the volume does not dissipate nearly as quickly as point source systems. Horns can make up for this with extreme efficiency and controlled dispersion. Other dynamic speakers not so much.
System that sounds so real it is easy to mistaken it is not live
My current stereo system consists of Oracle turntable with SME IV tonearm, Dynavector XV cartridge feeding Manley Steelhead and two Snappers monoblocks running 15" Tannoy Super Gold Monitors. Half of vinyl records are 45 RMP and were purchased new from Blue Note, AP, MoFI, IMPEX and some others. While some records play better than others none of them make my system sound as good as a live band I happened to see yesterday right on a street. The musicians played at the front of outdoor restaurant. There was a bass guitar, a drummer, a keyboard and a singer. The electric bass guitar was connected to some portable floor speaker and drums were not amplified. The sound of this live music, the sharpness and punch of it, the sound of real drums, the cymbals, the deepness, thunder-like sound of bass guitar coming from probably $500 dollars speaker was simply mind blowing. There is a lot of audiophile gear out there. Some sound better than others. Have you ever listened to a stereo system that produced a sound that would make you believe it was a real live music or live band performance at front of you?

@lewm , tell me about it. For some strange reason Sowter stopped making ESL transformers and the ones I have found are peanut 50 or 75 to one jobs that will not handle the power I could throw at them. That resistance is primarily in the treble region, that Brilliance control which I roasted fine tuning it. I substituted the appropriate sized power resistor and it will heat the chassis almost to the point where you can not keep a hand on it. More wasted power. You still have to keep a resistor on the primary for most amps, just an ohm or two to keep them from shutting down. Since I take the bass and can fine tune the frequency response digitally I should easily be able to get away with one transformer and maybe a resistor if I could fine one with suitable power handling. I do not think the HF toroid will handle it. Roger is of the mind that you do not want to modify his speakers for any number of reasons. @atmasphere , Ralph, do you know any makers of ESL transformers that could supply a 100:1 step up able to handle 200 watts continuous with a frequency response of 100 Hz to 20 kHz? |
richopp: I also have difficulty placing things during that time period for some reason. Duane died when I was a sophomore in HS, so that narrowed it down to 71 (as I recall that it was around Halloween). I saw them in Des Moines, Winter of the following year, and ended up driving to Illinois to their next concert the following day. No Dwayne, but Betts was incredible (playing from a pool of sweat both times).

Dear @mijostyn : My dynamic type speakers can be operated in line source or point source fashion, we have to remember that ADS designed it as true proffesional/studio monitors and not for home systems.
My seat position is at 2m.-3.m. and sensityvity ADS spec is 95db. Normally I listen it in the 80's db SPL and only go to 95db SPL at seat position or even a little higher when I’m testing or comparings audio items. I like to take care of my way limited ears.
Btw, thank’s @atmasphere .
