Sundown NeoPro Rolloff Question

I'm going with some 6.5" NeoPro's in the doors for an active setup with Alpine Type-R Silk dome tweets.

Simply wondering, can I allow the NeoPro's to rolloff into the tweets naturally without a high side crossover and just a low side set at 55-65Hz, or should I aim to crossover the high side at ~3-4kHz?

The tweets, I have figured out from my own experience, sound best crossed at 3500Hz, so regardless of the NeoPro crossover, I'll be putting the crossover of the tweeters at that point.

My own opinion: Mids sound MUCH better with a proper low pass crossover

You wont damage anything trying it if thats what you are worried about. If it were me, start with them running wide open at the top and then just start bringing the crossover down until it sounds best to you.

I would cross them, I have mine at 3500 and it is much better then when I tried 4khz...i don't have any idea what they would do if I ran them full pass but I don't think it would sound great.

Shower farts still piss me off.

I think theyre pretty neat. When the water runs down your crack as you let one out... its like shitting in a crockpot.

Well, here's the thing. I have an MB Quart 2 channel amp which can feed them 150 watts RMS, which I've been told they ask for even though the RMS on the NeoPros are 100, or I can use my Sundown SAX 100.4 which can run the crossovers on both high and low side using the subsonic. So either starve them on their RMS power, or feed them the power that gets them moving well and cross them over the right way.

Yeah, mine are only on 55w, and IMO they get too loud for me. So I would use your sundown.
