we were to calibrate the bl50’s in narrow mode, in 3 different positions( 3 times when you move the mic 3 times with in ~30cm), then combine those filters and have them play in wide?

Or vice versa, where you have the speakers calibrate them in narrow mode, but put the mic in 3 different positions, like you would when setting them up in the wide calibration (one mic position per one seating spot), and then use that filter for narrow mode?

I know it’s a bit odd, and let me know if it makes sense?! I have one filter setup in wide mode calibration where i calibrated them in like it says to do in narrow mode(with in that virtual box around your head at ~30cm appart) and that sounds more accurate to me than when it’s done along 3 positions along the couch. I also happen to like the sort of airy feeling wide mode give you on the 50’s compared to narrow mode with the same measurement place and method.

Sorry... but I'm still a little confused...

Remember that the ARC measurement and resulting filters only work from about 2 kHz and down. Any differences in the timbral behaviour above that are going to be different from room to room (more precisely, as a result of your sidewall reflective characteristics and the relative locations of the loudspeakers, the walls, and you.

The ARC filters will also be different in Low and High latency modes, because they have to compensate differently for the different coupling of the loudspeaker to the room modes (primarily).

You say that the 50s "sound quite different" in wide and narrow - but this is to be expected, in my opinion. If they didn't, then there would be no need to have the two modes.

I guess that the "airy feeling" that you're enjoying in Wide mode is primarily the result of the sidewall reflections. The more obvious this is, then the more it indicates that you'll also get more high frequency content as a result of those reflections. You could attenuate this using the PEQ, however, if you prefer it, then this is a bad idea. :-)

I also don't know what you mean when you say "sounds more accurate" - with respect to timbral balance / overall spectrum? Phantom imaging locations and precision? Temporal control (i.e. lower levels of frequency-dependent ringing?)

All of that being said, we often see when doing listening tests where we ask for a listener's preference between "A" and "B" is that they want something in-between... I'm starting to form the opinion that this is human nature: given a choice between two things, people will want something else.

When I give my dog the choice between two things, it always wants both.

Also - I remember - when my kids were young, they too wanted both…….instantly.

Good point... but the average is just half of both... :-)

OK, since we're talking about what's possible, and not possible, with the 50s, I have a question for Geoff, should you be so kind as to reply--as my 50s will be arriving at port any day now, and will be installed sometime in July.

I recently developed a case of tinnitus from an ear infection, and though the infection has healed sadly the tinnitus hasn't gone away. According to my ENT/audiologist, my hearing is completely normal without any discernible loss (at least within the range they test), but it may persist for some time.

I've I've been able to pinpoint my tinnitus to a ringing tone in both ears at exactly 10Khz at a volume of approximately 7%. Is there some way, in the setup process for the 50s when we calibrate them with ARC, that I could compensate for that and create a (hopefully temporary) setting to negate the tinnitus while listening to the 50s?

Hi,

Sorry, but as far as I know, there's no way to negate tinnitus. If there were hearing loss, then it's quite easy to use the parametric equaliser in the Beolab 50 to make some kind of compensation for this - although it would be difficult / impossible to do it "correctly" whatever that means.

To my knowledge, the only external way to deal with tinnitus is to mask it, which means making the external sound simply loud enough to "down out" the internal sound. However, this means turning the entire signal up - not just one frequency band - which is not necessarily a healthy option in the long term.

Actually, at the last visit to an ENT/audiologist, I learned that many / most / all people have tinnitus - the only differences are the frequency and the level. For many / most people, the level is so low that normal, everyday noises mask the internal sound(s). It's only when sitting quietly in a quiet room that you find out you have it. This is similar to suddenly learning that you're colour blind when having a conversation in a paint shop over the choice between "white", "eggshell", "ivory", "vanilla", and "alabaster" for painting the hallway.

Thanks, Geoff. That's what I figured, but it was worth a shot--and I appreciate your quick reply. Regardless, I'm very much looking forward to getting the 50s properly set up in my system. Can't wait!

Hi Geoff,

I was wondering the other day if it is theoretically possible to make the Beolab 90's beam width even narrower through DSP? Or would it require additional side firing drivers to decrease the energy sent to the sides? And would there theoretically have additional benefits or disadvantages to an even narrower beam? 

Thanks,

Ray
