As the title says- where did you finally end up with your crossover? As it turns out, my SPL meter has gone flaky, and in the meantime I just got a new sub. If it matters, I’m using the sub internal crossover and the speaker level inputs- no bass management in the system. The internal crossover uses a 24 db/ octave slope.
My balky SPL meter is showing, and I’m hearing, bass beginning around 40 hz from the M3 when using the ‘Sound Check’ cd from Alan Parsons. I will experiment, as I know every room/ placement/ etc. is different, but I can’t help but think that some good collective knowledge is out there.
Thanks,
Jim

i am a longtime and steady sub user (pair of rel strata's) with many speakers like quad, harbeth, proac, epos and so on

but with my m3 sapphires i feel no need to hook up subs

I tried dual subs and single sub, and I found the M3's don't need them and in fact hinder their performance, no matter how low the setting was, even 35Hx crossover point. The M3's are so coherent from top to bottom, and if the recording has deep bass the M3's will give it to you like you had subs in your room. I use the subs on my video system now to great effect.
