A full range speaker?
Many claim to be, but how many can handle a full orchestra’s range?
That range is from 26hz to around 12khz including harmonics, but the speakers that can go that low are few and far between. That is a shame, since the grand piano, one of the center points of many orchestral and symphonic performances, needs that lower range to produce a low A fully, however little that key is used.
I used to think it was 32hz, which would handle a Hammond B-3’s full keyboard, so cover most of the musical instruments range, but since having subs have realized how much I am missing without those going down to 25hz with no db’s down.
What would you set as the lower limit of music reproduction for a speaker to be called full range?
I’m asking you to consider that point where that measurement is -0db’s, which is always different from published spec's.

If I were to build my dream speakers these would be the foundation of them. Scan-Speak 32W/8878T11 Revelator 13" Woofer https://www.madisoundspeakerstore.com/approx-12-woofers/scan-speak-32w/8878t11-revelator-13-woofer/ Or these in an open baffle, which is the way I'm leaning these days. AE Speakers http://aespeakers.com/shop/dipole/dipole15/ And these would be something like what I would build, putting it all together into the expense of the components, and you’re talking about $1,200 just for the x-over parts.

AE Speakers http://aespeakers.com/shop/dipole/dipole15/ ~~~~~~~~~~~~~~~ Why the need for a 13 super bass anda 15 inch dipole woofer??? bass on top of bass???? My dream speaker would be Seas W22 Graphene xossing at say 200hz/Mundorf high end caps, and a Vox 5 incher. Thats a huge waste of the W22 Graphene. |
Doing the math. Sound travels about 1100 feet/second at sea level, and for you nitpickers, at 50% humidity and 72 degrees. A cycle of 25hz happens, surprise, 25 times a second. Divide 1,100 by 25 = 40 ft. A 25hz tone is 40’ long, but it happens 25 times a second, so that frequency sustained for 1 second travels 1,100 feet. While 10khz travels 0.11 feet per second. So, if you are 1,100 feet from the point source of sound you may notice the Doppler shift in tone. But at normal listening distances? Nah. Don’t even think about thinking about this if you’re having a drink and listening to your system this evening, because the phase shift between those lows and highs, of say 10khz is dizzying! 😂 |
