70: Why Are You Doing Speechlift from the Can?

AV SuperFriends: On Topic
Why are you doing speechlift from the can?

Recorded April 17, 2026

In this episode, the crew turns a simple question about classroom speakers into a full-blown AV theology fight. Should small classrooms use ceiling speakers, front-wall point-source speakers, voice lift, program audio, or whatever happens to be lying around in the warehouse? Naturally, the answer is “it depends,” followed immediately by 35 minutes of everyone insisting their version of “depends” is the only sane one.

The discussion gets into the real-world mess of higher ed classroom audio: even coverage, voice lift thresholds, ceiling lay-in speakers versus cans, front-of-room program speakers, accessibility systems, bad acoustics, noisy HVAC, amplifier/speaker mismatches, and the eternal question of whether “good enough” is actually good enough. Along the way, the panel debates physics, budget, installer convenience, student experience, and how many speakers it takes before a room becomes less of a classroom and more of an ersatz municipal warning siren.

In short: if you’ve ever looked at a classroom audio system and wondered, “Why did they do it that way?” then this episode provides several answers… all of them wrong, all of them defensible, and most of them louder than necessary.

Alternate show titles:

• It’s diapers… it depends
• Do we still do speech just from the cans
• SAR method: sounds about right
• How many rooms do you have like this?
• Could they add a column in the middle?
• They can hear all the accounting numbers, they just can’t see ‘em
• Not the EASE software, but ease of install
• I had to throw them away
