What's the lowest anyone crosses 6.5 comps over at?

[eharri3 10+ year member]

Here's my beginner's setup:

Alpine CDA 9883

Eclipse 4 chan EA4200

Eclipse SC 8362 2 way components in front

Infinity Reference Coaxes for rear fill

Soundstream Lil Wonder 2 channel sub amp bridged and powering Pioneer Premier 10 inch shallowmount.

It's hard to tell from the dial on the amp but guessing based on the instruction manual I would guess my Eclipse front components are high passed at about 55 HZ or so after I tweaked them a bit. Everything sounds good except in some songs I just wish I could bring a touch more bass to the front stage but I always hear 80 HZ as being the hard, fast rule for the lowest 6.5 in door speakers should be crossed over at. Anybody here run them lower or run them full range? Everything starts blending perfectly at about 50 HZ and I think the car audio shop that installed them set them at the notch for 47 and the sub blended perfectly at this setting but I bumped them a little higher for the time being because I wasn't sure if this might eventually hurt the woofers.

I guess I'm just wondering if I could safeley cross these over at 45-50 HZ with the gain and everything else properly set and if anybody else crosses 6.5 comps a little lower than what the textbook says. Or am I getting all the bass I can reasonably expect out of them and it's time to start looking for woofers that offer better midbass. If I need something better, can anybody recommend one 6.5 inch woofer that covers midrange and midbass frequencies well?

I run my mids at 63Hz with a 24db slope and they blend rather nicely with the subs and have plenty of midbass.

You might be trying to get more out of them then they're capable of...

try crossing at 80hz with a little EQ boost around 80-150. it's more about having mid-bass presence up front than it is getting low up front. you could also try a slight gap in between your sub and your fronts to get them to blend better.

You might want to try to bump the sub up more too. What's the slope on that?

Im gonna be honest here. Im a newbie and the only way it's ever been explained to me prior to this was get as much bass out of the fronts as possible to blend with the sub. I just took that to mean get them to go as low as is safely possible. I've been trying to resolve this blending issue by continuously monkeying around with crossovers and detuning my sub for quite some time and was at the point where I just didn't think I had the right equipment to get it right without cutting sub frequencies to the point where my sub's output wouldn't be satisfactory anymore.

I was skeptical about your suggestion but I ran out and bumped the high passes up by a bit to over 70 HZ then set the EQ on my 9883 to keep the bast boost at zero but center it at 80 HZ instead of 60. Im now getting at a little bit more of the midbass i've been looking for up front. What's more, now that my mid ranges can concentrate on reproducing more of the frequencies they were designed for and less of the ones that they weren't in addition to the stronger midbass, the mid range is alot crisper. Things like pianos and guitar notes sound more defined.

Thank you. I am MUCH happier with my sound quality for now and am glad I don't have to run out and buy midbass drivers and figure out how to fit them for the time being. I guess it just goes to show, make sure to you know how to get the most out of what you got before you run out and buy more stuff.
