Subwoofer upgrade and frequency response

[tjtremor]

So finally ordered a proper sub for my music listening with my Klipsch rp-600m. Current sub is cheap kind & very old 12". It easily rolls off after 80hz without EQ and it's not high wattage.

Now given the huge roll off, I don't have issues with bass notes definitions or volume for 30hz, 40hz, 50hz, etc All sound fine to me even with Klipsch pushing 95db+


12" old SUB freq response, red line estimate of monolith THX 10" response

As a fun experiment, I EQ the thing and added +20db gain on the LFE out and I noticed I'm actually not liking the heavy volume for lower frequency. I guess I'm sensitive to lower frequency. The lower they get , the lower the volume I like.

How would changing to a flat response subwoofer that has roll off at 16hz change the sound for music ?
Would I need to add EQ to have it drop -10db -15db early ?

Is this a near-field (anechoic) measurement?

yes, was 70cm; that's how close I sit to the sub

perhaps you should measure the sub at 2 cm distance. With the ports closed with socks if available.

Make sure that you drop down the levels considerably when you measure at such distances.

Are you using Windows for the measurements? Have you confirmed that you have turned off Audio Enhancements?

I've seen many cases where it is left on and the resulting measurement shows early roll off. See this an example -> https://www.audiosciencereview.com/...egration-whats-your-take.28813/#post-1003474?.

100% weird, thanks for mentioning that
no idea what Microsoft is thinking with their crap software / hidden options


no audio enhancements

audio enhancements enabled, crap roll off and 85hz boosted
