Yes.

Yes.

The C-weighting (+1dB for typical Rat Shack meter errors) is a decent measurement of what we hear at reasonable volumes.

At very high volumes (over 90dBA), an unweighted SPL measurement is better.

I think you said your room was 14' by 14'

The lowest room mode (standing wave) would be about 40Hz. (565/14ft)

The "modal zone" would be above 40Hz. = no standing waves below 40Hz.

Unless your room was unusually well sealed (rare), there would be no cabin gain below 40Hz., and placement in a corner would not affect the bass below 40Hz. For those huge wavelengths, any spot in the room would be "near a corner".

Your small room should provide smooth bass under 40Hz. ... but a rough bass frequency response for a few octaves above 40Hz. based only on the dimensions (aka armchair analysis).

Good evidence that a small square room is bad for bass - Richard BassNut Greene 09:28:17 01/14/09 (3)

Yep - what kind of problems should I expect with my new room? - VynylTap 17:13:15 01/14/09 (2)

Do you have any flexibility with the room dimensions? ... - andyr 18:16:12 01/15/09 (1)

Forget the rough graph with too few data points -- listen (to a slow sinewave sweep or bass tone burst test tones) - Richard BassNut Greene 08:28:52 01/13/09 (6)

I understand - and will try - VynylTap 09:23:57 01/13/09 (5)

The Rat Shack Meter IS most useful for bass -- most people are clueless about "error corrections" - Richard BassNut Greene 09:11:53 01/14/09 (2)

so really, the graph should look more like this... - VynylTap 14:29:39 01/14/09 (1)
