hypoman is the first, and only, contributor to this thread to even mention an essential parameter relevant to almost every other suggestion: that the SPL meter must be properly "weighted." The meter elliotbnewcombjr actually provides a link to will be useless for measuring bass output: it is "A weighted," which does not register anything below 100 Hz. The vast majority of such inexpensive meters available on Amazon or eBay are "A weighted," like the one in that link, which are intended for measuring industrial noise levels, not music. I learned this the hard way: I acquired one of those "A weighted" meters, and was puzzled that the readings I got seemed impossibly low for the subjective loudness they presumably measured. A device that will allow you to switch between "A" and "C" weighting will dramatically reveal the difference. And since the OP is interested specifically in "how low" his speakers will go, none of the suggested meters in this thread will be of any use at all in determining this.

OP wants HZ but gets SPL (“I didn’t order umm”) suggestions as though he were the brain dead one. LOL.

dgluke complains that suggesting SPL meters when the OP had asked for Hz is "braindead." But--duh!--Hz are audible as SPL. And then dgluke suggests the Hsu test tone CD, like everyone who mentioned SPL readings also did (even if not the Hsu CD specifically). The easy way to "measure" if your speakers go down to 20 Hz, or 16 Hz (if you’ve got a Hsu sub, apparently) is to play such a test CD and LISTEN! If you can’t HEAR your speaker producing the tone, measure the output with an SPL meter. If you’re still skeptical, take the grill cloth off and watch the cone move. |
B weighted is the method used in stereophile in my experience reading the magazine. A weighted is used at times as well. But this is all nonsense. Mentioning it is nothing more than adding your own attaboy. SPL and spectrum analyzers made for audio are not going to have to be taken off construction mode in order to measure your speakers. My dB meter has an OSHA mode, among others, but it is still measuring music…because that’s what it was meant for. Buy or download music related products and stay off PPG, manufacturing, farming, aviation and construction safety we stores and you’re golden. A simple google search turns up excellent no brained results. I believe you’d have to go out of your way to mess this up in the way you suggested. https://www.stereophile.com/content/measuring-loudspeakers-part-one-page-4ok |
