... i almost completely covered my listening room's ceiling with those Styrofoam RPG skylines copycats ... Very good at dispersing the sound !

BTW, i have a purpose built listening room, built to Robert Harley's no.1 choice of 10'x14'x19' dimensions. This was supposedly to have the best spread of eigentones (standing waves ) across the whole audio spectrum.
But it still needed alot of diffusion stuff & some absorption stuff to control those standing waves that clash with the musical notation frequencies (echo slap, comb effects, etc etc) .

It has a concrete ceiling, so when i first started, the bass was too much.

To quote one of the local hi-fi gurus: " It is better to have boomy bass than have not enough bass". Because with boomy bass, you can do treatment and stuff to control and reduce it.

But if the combination of your system and room already has got no bass to begin with, then you're screwed.

according to the old "Concert Series" (1st Gen Concerto and Concertino) manual, it says to place tweeter on the inside.

Actually when listening to hi-fi, one must not get too hung up about where the tweeters or woofers are.

The whole idea is to listen to the "music"; Not the round domes and cones vibrating like a monkey on caffeine.


Just try a few times one way vs the other, then stick by it and enjoy the music. Nevermind what other people say.
If tweeter outside seems to sound better, then go with it. Heck, why not ?
If placing the speakers upside down (Mission is already doing it from the factory) would sound better to you, go for it also!


That way only can the listener truly hear the music and enjoy the artistry of sound.

so .... have good speakers, good stands, amps, source, cables ......

the point being: remember to enjoy the music too

don't worry too much about measuring techniques.. as long as you use one method consistently... it should be OK already.

so.. anyone about to buy a pair of Sonus Faber speakers soon ?

just make sure there's plenty power to juice up the SF and it will sing nicely for a long time.

well, how much power does a TV or PC or even light bulb uses ?

How bright is your light bulb ?


How big is your TV screen ?
Plasma? LCD? CRT ?

What kind of PC ? 286, 486, Pentium, Pentium II, AMD Athlon, what Ghz speed ? How much RAM ? What PCI/AGP/PCI-E cards are on your motherboard? what graphics card are you using ? How many harddrives / CDRom drives / USB drives, etc etc etc etc etc ......

Exactly.

a well built amp should have its power rating double up when the speaker's load decreases. I had a really long winded article about Amp power ratings vs. Speaker impedances some time back.

... and don't forget to enjoy the music too

Maybe i should "copyright" the extreme toe-in method? hahahahahaha

But alas, i also learned this "technique" from a local Hi-fi guru back in the 90s.....
None other than Mr. Adrian Wong of Audio Image. He is also the pioneer in Sonus Faber together with the Penang hifi shop , and they were the very first to make Sonus Faber mainstream here back in the 90s.

Speaker Cables should NEVER be hanging like a clothes line:

Here's why:

1. It really doesn't affect the sound so much by leaving them on the ground. Really.

2. If someone trips over the cables and topples over the speaker or yanks the amp to go crashing down on the floor..... there's is ancient cantonese proverb for these kind of situation: "Taai Seei". (Mati Bagus). hahahahahahahahahahahahahahaha

Isn't RTA just awesome ! ... your own personal Audio Signal tone generator and Audio band oscilloscope !


So .... do share your accomplishments from using RTA for your hi-fi setup !

Added on June 15, 2009, 9:58 pmEh, what amp r u using to drive your SFCD now ?


This post has been edited by mugenfoo: Jun 15 2009, 09:58 PM

wanna try some "racun" on your SFCD ? I'm talking about the Krell KAV-300i .... guaranteed to make your SFCD sing in a way u never them sing before!

loan only mah .... won't cost u any $$$ one ! .. hehehehehe..

We can make it a 1/2 day session on saturday or something... can invite all the other SF kakis like Auronthas, pcwork, grandspy...

yeah ... good idea ! .. can someone "derma" his Kav-400i for half-a-day also ? ... i bet we can make this a super duper interesting day to test out the various combos ... Even better than going to hi-fi shop !

some SF speakers, KAV300i, KAV400i, .... mebbe some funny interconnects , a DAC or two ... etc. etc. All by enthusiasts only!

what amp r u using ? What source r u using ? RCA or Balanced connections?

Whatabout room conditions? is there alot of curtains , carpets in your listening area ?


140W into 4Ohms is probably only 70W into 8 Ohms.

.. and XLO

hey Car_o_scope ... i just realised that your Exposure XX looks different from mine ... yours has a front plate that is bigger than the overall casing (the edges protrude out from the rest of the main casing) , where-as my Exposure XX the front metal plate is flush and exactly the same edge size as the rest of the casing.... weird !

Do you know if yours is mfg in what year ? what serial no. ?

huh? What do u mean by "maximum room disaster" ?
