Axiom Home Page Forums General Discussion Stereo Bösendorfer

Besides Tori Amos, what other artists use a Bösendorfer piano, and what tracks should I look out for to hear the low notes? They really go down to 18 hz?

16.35Hz. I don't know who else plays this kind of piano. But if I ever need a fix of low notes, I just play the RealTraps CD .

Ha ha. I suppose if I was really cool I'd just have a Bösendorfer myself and learn to play.

Yes, just the biggest Bosendorfer models(over 90 keys)go down almost another octave below the about 27Hz for regular 88 key boards. Some classical artists play them(not necessarily the big one)but very little classical music calls for piano down there(Debussy's The Sunken Cathedral is one). That 16Hz note is also the lowest organ pedal, and appears(if available)at the beginning of Strauss's Also Sprach Zarathustra(movie 2001).

That's some cool trivia. Thanks!

A401,

I just tried the RealTraps tones with my EP600. The 600 does not cut in until 15Hz where the SPL is up 0.5dB from reference. At 16Hz, it's up 8dB. I have no problem whatsoever hearing and feeling the Introduction to Also Sprach Zarathustra from "Top 20 - The Very Best of Erich Kunzel and the Cincinnati Pops" which according to JohnK is the 16Hz note. This was coming in at 12dB above reference.

The reference level is 58.5dB SPL (this is relatively loud because compressor noise from my aged fridge actually carries down the stairs. This however does not interfere with listening). I had my Denon main gain set to -20 (which corresponds to 1W output per left/right channel at this frequency for my M80s). My 600 is set at ten o'clock, the Denon LFE is set to -6dB (the range is -12 to +12). The cross-over is set to 80Hz, lows out of sub only and the Denon set to stereo. I am in a 4,000 cubic foot, extremely tightly constructed, relatively live room with a large opening going up to my main level. I had the meter at the sweet spot where I normally sit. As you can see from my settings, I have plenty of headroom. When I turn the gain up at 10Hz, it feels like my

BTW, I run my sub about 6dB hot at 81dB SPL.

A more interesting and surprising scenario takes place when I set the M80s to large. At 10Hz, the SPL is up 0.5dB from reference. At 11Hz, it's up 3dB and by 12Hz it's up 8.5dB. I can definitely hear all these tones although I am sure what I am hearing is the room and not the actual tones. I posted about this before and Randy also witnessed it on his system but this is the first time I've posted any numbers.

Now even more shocking. I set the Denon to 7-channel stereo. This set the QS8 and VP150 woofer drivers quaking at 10Hz! Of course they are very small and are hardly pushing any air.

I vote that Axiom releases a mod to remove the so-called brick-wall filter below 15Hz provided it doesn't adversely affect the specifications at higher frequencies.

I think they would have to recalculate all of the speaker parameters and limiting logic to consider cone flapping from those lower frequencies. Not pretty.

Hi Bridgman and all,

Hey, do you all wanna hear air-conditioning rumble from recording studios and other recording venues that have not taken steps to suppress such infra-sonic noises?

You'll also get to hear cutting-lathe rumble on some vinyl recordings as well as inherent rumble from some much-lauded turntables--if you're still playing vinyl.

And I've got a couple of recordings with foot noises from concert pianists pedaling. Those resulted from inadequate isolation of the microphone stands near the piano. The floorboards transmitted the foot noise to the mike stand and up the stand to the mike.

There's a lot of garbage down there that's better left unreproduced.

Regards,

This should be entertaining...
