In Reply to: RE: How easy is it to blow speakers? posted by Les Anderson on July 23, 2016 at 11:47:22
does it happen with both digital and LPs? If it's only LPs, it's probably record warp and the bass reflex loading of the KEFs. A reflex speaker woofer can become unloaded at low frequencies like those of record warp and the only solution is a high pass filter or stuffing the KEF [ports which, of course, changes the speaker response.

You nailed it, I am accustomed to having a rumble filter engaged and the integrated phono stage does not have one. Wow, I have never seen woofers go nuts like that before! The amp is definitely punchier as well, but this is absolutely rumble.
I am going to look into a subsonic filter, thanks for your post.
Thanks

Ah, yes. You neglected to mention that you were using a subsonic filter on the previous amp, but not on the new one. Kudos to Hahaverizon for deducing that.
You would do well to inquire in the Amp/Preamp or Vinyl asylum to find out about ways/products to insert a subsonic filter into your system. Personally, I'm only familiar with putting a parametric or graphic EQ between the preamp and power amp, and that may be overkill for your needs, unless there are other frequency response issues you'd also like to improve.
