Dear colleagues,
I would like to ask you about your experience with the active crossover setting when 4343B bi-amped.
I’ve checked a lot of threads and ‘ve asked many questions (thanx Ian for your patience J).
First of all – trust your ears, so many tests and trials at home… but I’m still lost…
My room
17,5’ x 19,5’ /acoustical pro
Gear
Teac VRDS25 transport/ Lampizator DAC
Preamp Technics 30A
Active crossover: Luxkit Luxman A 2003 / Marchand XM26
Solid amp monoblocks Musa (bass) + tube monoblocks Luxkit Luxman A 3000
4343B --- toed in 12,5 / L-pads: MF turned max (+4); HF (+2); UHF (+2)
Placement
9’ apart (center to center) / 10,5’ speaker to listening position
back to my tests ...
1. Ian’s suggestion: “in BW 12db do use 230Hz and 350Hz as the 15 inch and 10 interact on the baffle. The logic is to minimise the coupling between the woofer and the mid vine by spreading thecrossover points. This recommendation is based on JBL crossover cards”
That is so interesting but I feel losing “weight” of sound. Lack of solid bass base (higher bass and lower mid) cause focus on HF. I could say – bright side
2. The other approach (230Hz / 280Hz) http://www.audioheritage.org/vbulletin/showthread.php?774-4355-3155-clones/page2
… here on the opposite way … loss of detail in the higher range. Here is the dark side ;-)
How to find the golden mean…?
Thank you in advance for any comments and suggestions.

PS. I plan to change the current 2121H on the 2123H and make a 4344mkII crossover… this may be beneficial?
