[78-L] A doubt about EQ curves

Sat Oct 15 15:23:51 PDT 2011

Well these speakers came with a computer I bought 6 or 7 years ago & don't have a brand name on them. I suspect that they are single cone or maybe 2 way with a little whizzer cone attached to the main cone. Since I'm not into audio restoration then those cheap "piece of junk" speakers will do for my present homebuilt computer. I've thought about putting in a good sound card (I use the sound from the motherboard) then hooking up a pair of B&W 801 Matrix Series 2's through a McIntosh preramp then through a pair of vintage 1960's era McIntosh MC-275's (75 watts per channel) wired for mono so that I get 150 watts out per amp. Sure it's overkill for a home PC but then I'm an audiophile & that stuff is just sitting around unused. The B&W 801 series is really power hungry capable of 50 watts to 1000 watts of audio power handling. They sound good at 150 watts & much better at 1000 watts. Thats not loudness but somehow the more powerful amps (McIntosh amps are
 great btw) do better with the 801 series of expensive (my B&W 801D'a are about 12k each retail) but then I've spent mega bucks on the living room stereo & not just to play vinyl or 78's. Golden ears perhaps? Yes I'm guilty of that but then I like my analog audio gear. Besides the Rodine turntable for all pre 1955 recordings plus transcription discs I also play 1955 & later LP's plus 45's on a Linn Sondeck LP12 with the lingo power supply & everything else. The amps & preamp is McIntosh so yes I'm a hi fi audio nut. Componant stereo, thats my thing. Always have been since my late teens when I was given the MC-275's after someone I knew died of old age. Should have took the speakers but then I didn't know anything about Magna Planer electrostatics other than they are very tall & thin.

>Computer speakers? The speakers I *prefer* to use are the Advent Large, connected to my Marantz 2265  (with the 'loudness' button NOT engaged). The second transfer station, in the heated basement, has a pair of KLH bookshelf speakers. Those roll off at about 16 kHz. Your monitor speakers I'll bet are rolling off around 13 kHz.

>Some of that high frequency hearing loss may just be a buildup of earwax that a doctor or nurse could remove (for us) once or twice a year. Of course there are over the counter products that can help keep it out too but I've never used them. the rest of course is age related graduel hearing loss or perhaps damage to hearing due to music played very loud on speakers or headphones as well  as other loud noise..

On the other hand my computer speakers seem to drop off at around 13.5 kiloherts when I've run an audio sweep test on them with the graph on my computer moniter. The question is, is that my hearing (with whatever earwax is there) or is that where my computer speakers start to really drop off? I don't know.
