Subject: Any examples for DIY subwoofers used in homes?

It seems than no two audiophiles agree on the effects of clipping.

I believe the original question was about driving a car subwoofer temporarily with a home stereo receiver or amplifier (wpc not mentioned). In my mind was 50wpc because it's tough to find a less powerful receiver these days. I believe the risk to the subwoofer is very low even if bass transients in the music were clipped fairly often.

What you described does not seem like the typical clipping experience at home (intermittent and related to bass transients in the music).

I surveyed people who build speakers / subwoofers but unfortunately their experiences matched mine -- damaged tweeters, but not woofers. I searched the internet for experts who would support your claim that clipping is far more dangerous to home subwoofers
(or any woofers) than excessive rms power but could not find any.
Perhaps you have a link or two?

What you described sounds like what could happen if one drove a ported subwoofer (with no high-pass filter or other protection circuit) with a 30wpc amplifier playing a 50Hz. sine wave with the volume control of the pre-amp at, or close to, full volume. Could any listener remain in a home listening room with the bass so loud, compressed and distorted?

Taking your post to the extreme:
- Assuming the owner's top priority is to avoid damage to his "200 watt power handling" subwoofer driver
used in a ported enclosure: If there was a choice of a 20wpc amplifier or 2,000wpc amplifier, which one would be more likely to cause damage to the subwoofer driver assuming the owner was able to completely ignores clipping distortion?
