Re: SPL meter acting weird
No spl meter I've seen has no weighting. At best you get to choose... Which do you have that can do unweighted?

Re: SPL meter acting weird
I have a flat mic but I have to use an spl meter to set the level. What frequency on c weighting is closer to 0 db but still in the sub passband?

Re: SPL meter acting weird
Umm my DEQ with reference mike, hitting the "meter" switch until I get an SPL screen.
I had the option of turning weighting off...

Re: SPL meter acting weird
wait what? DCX microphone input? Am I missing something? Do you mean DEQ?

Sorry yes DEQ. Can't remember for the life of me where turning off weighting was, but positive I did that...MissileCrisis wrote:wait what? DCX microphone input? Am I missing something? Do you mean DEQ?

Re: SPL meter acting weird
Hey everyone, so I bought the American Recording Technologies mic and I can confirm that the POS SPL meter I had was the culprit. It reads 20 dB higher (c-weight setting) than the POS at 40 Hz and 13 dB higher at 60 Hz. If anyone you know has any Pyle products tell them to give them away because their "C weighted" SPL meter was well lets just say a lot closer to A-weighted.
Thank you and I appreciate the awesome subwoofer Bill!

Re: SPL meter acting weird
This is what my mind was thinking when I had it near max volume and my insiders were churning like they do at a concert but the SPL meter disagreed.sine143 wrote:hehe. I could have told you for SURE if you had mentioned the brand name earlier!!!
Is how I felt when I turned on the new meter and realized that the Pyle of crap (pun intended) was ~20 dB off at low frequencies.

Re: SPL meter acting weird
Example picture....
If you've read my build thread post it is the same one but for those who haven't seen it. Measurement taken at roughly 1.4 V inside in a corner at ~7 feet away. 40 Hz, so need to add 3 dB to account for the C weighting offset

Re: SPL meter acting weird
Inside it's louder than heck but outside it was very quiet. Looks like I need another one. I'll post the actual measurements (outside) by this weekend as realistically that's when they'll happen.

Re: SPL meter acting weird
Yeah the DEQ has the option for no weighting, it's actually on the screen where the db meter is, I think it's the middle button on the left of the screen.

Re: SPL meter acting weird
Since I don't have the details my best bet is my room equalizer wizard knowledge and setting the gain at 100hz compared to my new meter. The mic is razor flat and rewarding is free . Its a bonus that i can tell it to calculate for a dcx and it tells me the exact eq parameters. Now I just need to figure out why my low lows (<35) are dying. I briefly measured different listening positions and haven't found any yet that are considerably better in that range. Room acoustics >.<
