do components passive xovers usually have HPF's for the mids

[ppiflat10s 3]

I was listening to my stereo on the way home and stopped to get some pizza and waited in the car with the stereo on. I decided to not be a prick and I turned the sub off. I missed the bass so I turned my HPF off at the HU, which I usually have set at 63, and the mids actually do pretty well with the bass. I turned it back on and set it at 50Hz and it wasnt bad but theres so much bass im missing with it on. I am going to continue running the HPF at 63 when I have the sub on, but the times I turn the sub off I would like to disable the HPF to the mids to get some bass back. I was thinking of going to the amp and setting its HPF so that if I turn the HU's HPF off, the amps HPF takes over.

what do you think I should set this at, 35-40?

I listened to it only for about 8 minutes, but I had it kinda loud, and the mids didnt feel warm at all, no smell or anything, and they sounded pretty clear while playing, is it safe to just run no HPF while I have the subs off.

This may sound stupid at first, but they're safe up until they fail. Like any speaker, you can play any frequency on them. It's just a matter of how much power they can handle at that frequency.

I've never seen a passive crossover that comes with a HPF for the mids. You're probably better off just using the head unit HPF instead of stacking the HU and amp's filters when you have them both on. Your mids will be fine with the bass with no crossover until you hear them bottoming out or breaking up, which is normally pretty obvious in mids. You probably won't be able to play as loud as with them on, though. But if you want to play them loud, I imagine you'll want at least a 50 hz HPF on them, if not the 63. I would just stick with the system for filters you have in place now.

How are they installed?

Keep in mind that you have to quadruple displacement to maintain the same SPL for every octave decrease in frequency. So that means, for example, that if your mids are moving 3mm at 50hz to produce a given SPL level, they must excurt 12mm at 25hz to output the same SPL. Given the generally limited excursion of the majority of mids...this isn't really a good situation to put your speakers in. It's certainly possible to listen to the stereo with no HPF, but you're mainly gambling that you have the self control to always keep the volume at a level where this doesn't become dangerous.

the mids are installed into custom fiberglass pods in the doors. alright, I guess I will just st the HU at 80 when the subs are on, and drop it to 50 when I dont want the subs (generally means I want it quieter, not just minus bass) and turn it up less.

If im really trying to be loud, I listen to it at 45, normally drive around at maybe 35-40, sometimes only 30 (depending on album im listening to) and then with the subs off I listen somewhere in the 25-35 range. I have yet to leave the settings like I usually have them, except the sub off, and listen to the mids at 45(volume) to see how they do, I should probably do that.

and Im not trying to get the bass "as loud" as the rest of the freq. it plays when I have the subs off, it just seems a 50Hz filter cuts most the bass out, and a 63 seems to really cut out all the bass. I dont think my mids lack in playing 63+ tones, because I have a few sweeps (20-20k with no subs doesnt seem to really show dips in response til it gets to the highs)(100-10 with subs on and crossed at 80, it seems like the mids do fine with the 100 - ~80 part)

if I can safely have the mids crossed at 80 at volume level 45, should I be able to run no HPF at 25 safely? (I know noone can give me a 100% answer, but a good guess is fine with me)

If your mids aren't vented and in "too small" of a pod you could have a pretty steep mechanical roll-off (ie crossover) such that you don't really need one. In other words you could be cramping your drivers and destroying their low frequency response.

they pretty much got the whole door. well, a small enclosure with a 6" hole just past the magnet of the driver that leads to the door, so I dont think its that the enclosure is too small. Ill play around with the settings tomorrow and see what sounds good.

[///M5 2,833]

6" hole is way more than big enough, so you're set there. Lots of people cramp drivers though and never realize it, glad that isn't your problem.
