Why don't we use smoothing on our measurements?

The measurements and graphs here seem to be really rough and noisy compared to most of the other ones that are seen in other places, why is that?

Sealed vs Bass Reflex vs Tapped Horn

What effect does loading the exact same driver into these 3 major enclosure types have on various aspects of performance? If all 3 were EQ'd into the same basic response shape how would each perform?

Investigating Room Gain, "How much boost is my subwoofer going to get?"

This is an investigation of how much more gain a subwoofer is picking up by being placed into the confined space of a random room over what its baseline outdoor ground-plane SPL output is.

DTS-10 vs. DTS LMS-R

The standard DTS-10 tapped horn system compared head-to-head against itself with the stock driver swapped out for a pair of TC Sounds LMS-R 12ís. This review shows the tradeoffs from using higher excursion, higher power-handling but lower sensitivity drivers against the native DTS-10 Lab 12 based drivers.

Dual or triple opposed SPL compensation

Dual or triple opposed subwoofers have drivers that fire from opposing faces of the enclosure and radiate with equal power over the entire operating range of the device. The sum of the sound pressure does not measure the same in a half-space environment as it would with a single radiating surface orthogonal to the microphone. Some of the radiation points end up further away and pointing away from the measurement microphone, which under represents their peak SPL capabilities during outdoor measurements. This is a look at developing a compensation file for these types of subwoofers and whether it is indeed warranted for this scenario.
