HUMIDITY

Well below the dew point and consistent, no large swings from one extreme to another.

0%??
Good luck with that.
The relative humidity in Death Valley is currently 6%!

Oh...
Not to mention the static electricity issues you'd have below 30%.

I should have said "above" the dew point (dry).

Forty five to sixty percent has worked well for me for over thirty five years. Lower end during summer months and closer to sixty during the winter. No worries!

 Hope you don't live in a cold winter climate to keep 60% humidity your windows will have ice on the inside. If you run a whole house humidifier beyween 35 and 45% and you will need to dial that down in very cold weather to around 25% maybe lower in sub zero weather.

You need new windows, or perhaps need to replace the glass in your existing windows.

Thanks to all. I'm in Fl so with the a/c it's usually 38 to 46% sometimes lower in the winter.

They are new triple pane windows in an energy efficeint house it has nothing to do with the windows it has to do with to much humidity in a house  in very cold winter climates. Actually the tighter the house the worse the problem running whole house humidifiers. That's why whole house humidifiers with automatic humidistats adjust the humidity down as the temperature drops. 

40-45 is ideal helping your rig sound more full bodied and musical. 

That's optimal between 35% and 45%.

If your windows accumulate moisture on the inside during the winter, there is something wrong with the windows, or the glass within them, or the way the windows were installed.  It doesn't matter if they are quintuple-pane, or built yesterday. Don't take my word for it, even though I've lived in cold climes all my life.  Check the window warranty. Consult with an expert.

I did consult with an expert that’s why I know it was the whole house humidifier keeping the house to humid the expert switched the hunidistat from manual to automatic and it was a miracle no more ice on the windows.

The expert also informed me I was probably getting ice in the walls as well that's why it's best to let the humidistat control the humidity as it adjusts for outside temperature changes.

You must run your A/C almost non-stop if you're achieving those levels in FL. You might want to check the accuracy of your hygrometer. Normal "comfort zone" is between 40 and 60%, above that exists high potential for mold, below that leads to static and greater potential for airborne illness. The important thing for speakers is to avoid sudden, large shifts in relative humidity, this is especially true for cabinets constructed of solid wood or plywood.

I set my a/c at 79-80 degrees. Humidity is 38 to 48% I average 24 kwh during the hottest months and 14kwh the rest of the year. I have great insulation. The room is 18x12.5 8 foot ceilings and about a total of 1185 sq feet. I check the meter daily and keep my elec bill under 100.00 per month. Very rarely open the windows.

I live in the south too. Keep the A/C at 77 or 76 in the summer. Old drafty house. Humidity is kept at comfortable levels. What number? Who cares? If our equipment can't run optimally at comfortable temperatures and humidities then we need different equipment or a less insane hobby.

Not only does humidity affect equipment but humidity, and temperature, also affect the acoustic envelop in your listening space ( a 10% swing can dramatically change the reverberation field by messing with the response of the higher frequencies which provide much of your spatial cues ). Concert halls are generally designed with HVAC systems that can easily ( and quietly) produce constant temperature and about 50% humidity with any and all crowd configurations.

fifty/fifty always sounds and works best.
May 50/50 save you
Praise the 50/50
Oh My 50/50!

Is it safe to assume that all above posts were talking about relative humidity?
