-
- Playing loud isn't the whole answer. Playing loud and accurately is.
-
- That being said, let me destroy any credibility I have on the net by
- saying I have heard good Cerwin Vega speakers. Really!
-
- But they wouldn't sound good connected to a K-Mart receiver, that's for
- sure. I bought a set about 15 years ago, maybe more. They sounded so
- good at the demo - it was a mall wide affair where all audio dealer
- participated and CV themselves had things set up. I went home and
- brought some of my LP's. Really decent. So I bought the pair.
- Somewhere about $800 then.
-
- I took them home and was heart-broken. They sounded like crap - to put
- it mildly. So I tried changing a few things. Out with the Dynaco
- pre-amp. Hm! Voice sounds better. Out with the Garrard changer.
- Better. Replaced ?? cartridge with a Micro-Accoustics eletret 630MP -
- about $300 in 1977 dollars. Amazing. They really are pretty decent
- speakers, BUT they showed up every flaw in the system.
-
- CV and one or 2 other make highly efficient speakers that are
- affordable. In the Audio October Equipment issue - I just visually
- scanned the loudspeaker area. Most of the CV's are close to
- $1000/pair.
-
- There are 2 or 3 other mfrs that list 100db spl at 1 watt at 1 meter
- who have some cheap speakers.
-
- However the majority of the highly efficient speakers are $1000 and
- up. WAY UP!. Up to $75,000 per pair.
-
- And the efficient Apogges are in the $30,000 per pair range.
-
- Now - if you have never heard high quality highly efficient playing
- dynamic audio - you have really missed something. Note I said 'audio'
- and not music.
-
- On 2 separate instances, listening at high levels, my body wanted to
- invoke the 'fight or flight' syndrome. One was a locomotive
- recording, the other was the jet flyby from Digital Domain.
-
- With wide range speakers, highly efficient, and power in the 200 w/p/c
- range on peaks - your body and your mind told you two different things.
- Your body wanted to run, because you were about to be hit by a
- locomotive while your brain said no - that's coming from the
- loudspeakers.
-
- The body gets confusing clues. On lesser systems you either limit the
- dynamic range on the low end - where you feel the sound and not hear
- it, or there are distortions that tell your body/brain that you are
- hearing a recording. These things sounded real!
-
- I don't know if you'd ever need this much to handle just music,
- particularly a string quartet, but on non-music it was really amazing.
-
- I remember in the early days of "HI-FI" that the standard jokes
- revolved around things like never listeing to music, just locomotives
- and such.
-
- I have always beleive in efficient speakers with sufficient power. My
- current speakers are recording studio monitors (I spent a lot of time
- in studios at one part of my life). I have a set of Fostex LS-3As.
- (Fostex makes some expensive high end stuff too - not just the cheap
- little multi-tracks they seem to be known for). Rated at 103
- db/1w/1m. UGLY!!! Heavy - 170 lps. A studio in town has their
- LS-4s. To get an idea of size of those, picture two 18-20 cubic foot
- refrigerators laid on their sides, with horns and a slot radiator
- tweeter grafted to the top.
-
- The only speakers I have seen that were bigger than those were the
- Tannoy "Dreadnaughts". GAWD they were HUGE!. Memory dims over the
- years, but they had either 4 or 5 15" woofers per cabinet. They were
- supposed to be control room monitors but you'd have to have an awfully
- big room to put those in there.
