What stops the same thing from happening? Is there something in the crossover that limits the signal, like a HP filter ? The same thing will happen with the Cornwall. At the very least it will cause unwanted distortion from excessive cone movement, worst case a blown woofer. The high pass filter settings are there for a reason.

MEH Synergy Posted October 19, 2018 Share Posted October 19, 2018 I don't think it will make a significant difference either way unless you are stomping on the sub hard with at least the rated power amount. For pro application at full output, I deem it mandatory to not blow gear up (even if the amp doesn't clip). For home use, I kind of doubt you are ever going to approach that subs limits.... You will approach the cops and neighbors limits much sooner. Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted October 19, 2018 Moderators Share Posted October 19, 2018 It just does not make sense to me. A Heresy only goes down to 58Hz and many people with SS and tubes sending a full signal and I would think they would hear distortion, and you never hear of drivers blowing out or anything else ? Many speakers have been played a full signal for a very long time. I never did understand how it was a problem, I thought the driver would do nothing if it were to low for it to reproduce. Could be why I'm not building speakers Quote Link to comment Share on other sites More sharing options...
MEH Synergy Posted October 19, 2018 Share Posted October 19, 2018 I believe he is speaking about the theoretical stress that a ported woofer MAY endure if improperly designed. They always warn you in car audio if you try to go big and extreme to use a subsonic filter. The higher that filter is, the more headroom you will have and the less stress the amp and woofer will endure. In a, sealed "Tuning the port is a science and is done through calculations including the size and length of the port among other things. But if a port is not tuned correctly, it can limit the performance of your subwoofer(s) and/or have a damaging effect that may eventually cause your sub to fail. Improper tuning will still cause unnecessary stress, and will hinder performance." I wouldn't consider using one except on a rare occasion if I wanted to push speakers to their limits and not worry about clipping the amp and blowing drivers. I would be much more worried about smoking a tweeter than a woofer any day. I had stated in another thread here that I have NEVER seen or heard of a smoked woofer ever before. I wouldn't worry about these things for home use.... 1 Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted October 19, 2018 Moderators Share Posted October 19, 2018 It seems both sides make sense to me, must be only in certain situations or you would hear about much more of a distortion problem and ruined drivers. No one thinks twice about connecting a bookshelf speaker to a receiver to play a LP or CD even very loud, where does that extra signal go below the tuning point? You could play it like that for 6 months straight with no problems, it seems to not be a problem for the driver even for really cheap speakers/drivers. Just one of the things I don't get I would guess more people have a much better chance of over pushing their sub compared to the mains.
