Active 4th order XO recommendations for the RD0690 tweeter
Options
Only GENUINE help PLEASE! - NO discouraging replies.
I think @ or just below 2K Hz should work. Please read on
My HT speakers all use the same tweeter w/, per Polk, 2nd order filtering, XO’d @ different frequencies.
Speaker specs, points to consider, and questions:
1. per Polk, one speaker has a 1.8* Khz XO frequency
2. ...maybe kinda low for a 2nd order XO?
3. ...spec possibly inaccurate w/only 9.57 Mfd of filtering
So... ...if that 1.8K 2nd order spec is for real, then 1.8K 4th order should work great for all channels, right?
* RTi A1. CSi A6 - 2.2K; RTiA7 - 2.7K
Thanks in advance, tony

VERY late update (about 2 1/2 years overdue...):
4th order 1.9-2K EXO works well - highly recommended! A gentle touch of EQ* in the right places moves my system up yet another notch making it even more “listenable” & enjoyable at any volume
Side note: change “#1” above to 2.8K; RTi A1 to ‘A3** yet to be modded/EXO, though they receive some similar EQ*.
That all said, viewing AND listening to “MIB International” was most immpressive. Looking forward to completing the next mod** (soon) followed by relocating & expanding to 7 channels. Possible tweeter swap(s) if I can find one (7) that fits!
