Linkwitz LXminis only go down flat to about 50 Hz. Added the 2 dipole woofer sections from the Linkwitz Orions that the LXminis replaced, Full bass down to 25-30 Hz restored. No brainer.
and gives me that proper feeling in my stomach and in my ass when a good bass rumble comes rolling through.
no sub(s) yet, but maybe in the future. My bookshelf speakers goes down to 34Hz so no urgent need right now.
I just thought I'd add my 2 cents because 34 Hz is awfully low for bookshelf speakers. Most three way floor standing speakers would do well to kiss 30 Hz. So if you're quoting a spec, it might be a very optimistic number from the marketing department (they all too frequently overlook how much of a dB drop occurs at that freq.)
I initially set the sub at about 120 Hz with a 12 dB/octave roll off. This frequency was higher than many would do (80-100 Hz appears to be the norm) but the math checked out. Anyhow, it got things close enough where REW and a bit of fiddling turned a ski slope into a reasonably level playing field in the near field. (Room modes are another matter, LOL).
I have done some test with REW and the specification seems to be accurate. But I have some room problem that I like to fix.

My guess is that your bookshelves are ported and pretty close to a wall/corner, as the REW plot.
@Krunok I'll dig thru my laptop files and post what I kept. I recall taking spl@requency from the B&W graphs, then adding these to similarly derived figures from my sub manufacturer to determine where the crossover would be the smoothest/flattest. Will post the traces though. MTF.
Yes, they are designed to stand close to a wall.My guess is that your bookshelves are ported and pretty close to a wall/corner, as the REW plot.
