Alright. I need to go active! I need a l/p frequency of 3500Hz and a h/p frequency of 4000Hz.

Harrison Labs' F-Mods come in 2500Hz h/p and 2500Hz l/p but I don't know if it's too low for my tweeters (Alpine SPS-1015, 4000Hz h/p supplied passives). And, since i'm overpowering the tweeters (rated for 50watts, but getting ~120watts), I don't want that to be a potential risk.

I know that 'SQ' and 'budget' aren't supposed to be in the same sentence, but what budget, quality 3 way active 12v crossover would you recommend?

Thanks.

Hmmm.... Good question. Can you not get F-Mods in 4K? I actually like those toys.

I do see a 3.5kHz module there...

Oh, cool. It's just that partsexpress.com only had up to 2500Hz cutoff points.

I'll just need to locate some of the 3500Hz models.

Are these reliable/trustworthy?

No moving parts, static settings... stackable for desired slope. So far, I've never known anybody to have any problems with them...

Alright. That sounds good.

Now, I would need 4 of them, totaling about ~$100.

Is there anything for less money out there?

EDIT: Nevermind, they come in pairs. $50 isn't that bad.

Thanks.
