[QUOTE="Peter Morris, post: 205535, member: 652"] I think that's OK - have a look at my measurement - the pink trace. I have some EQ suggestions in the double 10 thread which uses the 4594 + passive crossover with the RCF HF950 horn.... - BMS 4594 with crossover on RCF HF950 (not HE version) - Crossover – Linear phase 48 dB LR simulation @ 630Hz - If you don’t have a Lake I would use 24 dB LR @ about 675Hz 654Hz Q 0.96 +4.1dB 1K343 Q 0.69 -3.6dB 3K22 Q 0.33 -2.7 4K6 Q 0.68 +3.3 dB 8K49 Q .82 +2.1 dB 19K06 Q 3.1 +5.3 AP 1K895 Q 3.4 2nd order AP 12K35 Q 0.34 2nd order On top of that there 12 more raised cosine filters - 1 to 2 dB each for minor adjustments. The most noticeable would have been a dip - 2 dB .... 5K to 8K ish. [/QUOTE]
