is a rsl a rogers speaker?

Bought the 3600s, a good JBL4311 copy. Dome tweeter, level controls, ported with typical midbass bump.
Reasonably sensitive, easy on amps and would play pretty loud.

If I found some today, in good shape, they make fine speakers in the '2nd string system'....with a Vintage Sansui amp and a Dual TT........

I'm not getting any mid bass hump with the 3300's and the Accuphase combo. I like that I can turn down the mids too.

I've ordered a Dayton 30watt T-amp their $99 winsome mouse type amp, I'm excited to hear it with the RSL speakers.

They're not the end all be all, but there good, I think way better than the JBL 100's I had, more balanced and detailed.

They might like a good tube pre too.

Fun speakers.

All ported speakers have a double hump.

I once had an equalizer with cal'd mic and a warble tone generator. Had to turn down either the 60 or 125hz with my 3600s and it helped a LOT.

Room has bunches to do with what you hear, of course. If you got lucky and have a room and a listening postion which eats that frequency, so much the better. I was never quite so lucky.
