signal path ideas

[Bfowler]

need some insight for my brothers upcoming install:

gear:

rsd5 comp set
rsd6.5 mid
rsd300.4
tieq215ix
kenwoodx592 (has F, R, SW outs, and adjustable 24db hp crossovers for the F and R, and adjustable 24db LP for the SW out)


idea A:

use the front output to the eq215, crossover frequencies, high to the front of the 300.4, low to rear.

have all the decks crossovers turned off. the eq XO set at about 200, the hp to the 5.25 set. the lp to the 6.5mid



this is the easiest, but i'm worried leveling the output of the 5.25's with the 6.5 will be difficult.



Idea B:

use the front outs to the eq, then to the front of the rsd300.4
set the decks hp crossover at about 200.

send the rear out on the deck directly ro the rear of the 300.4. use the hp on deck at about 60. and the lp on the amp at about 200.

by doing this i can use the decks fader to blend the midbass properly. but i loose the eq on the 6.5's (in that narrow of frequency i can use the decks adjustable bass eq)



any thoughts people? am i overlooking anything?

i am partial to setup B. but let me know what you think

here's my thought's on head unit's with built in crossover's though it is very good to have them they have yet to have perfected it yet it's my belief that they add some noise and instabilitys in the signal. here's why i believe this my brother has a 5000 dollar tru tec amp paired with one of the top clarion units with the built in crossover. and all though his system sounds real good i noticed some background noise and instabilitys in the sound although most wont notice i did because i have no noise what so ever in my pg setup. so i would say go with the one in the eq because maybe bypassing the units crossover may get rid of this chance of noise and maybe even distortion.

so 47 views and thats the only input!

valid point. on option B i could use the amps HP crossover.

i think their scared of you B man or is it they want all your prized information yet don't want to spare any of their own because your from the land of the chosen audiophiles.

What about getting a 204 or 406.........

[Bfowler]

i have a 204, and a mx2.

where are you proposing i put it in the mix?



also...in looking at the eq...i have just realized it has a lpl port...

SO

i could do option A and use the LPL for the mids to adjust them, and have a second LPL for the sub!


keep the ideas coming!

I can't think of anything you're overlooking, but maybe I can help talk you through it nonetheless!

I totally understand your desire to have a level adjustment on the midbass drivers. I've installed and tuned several systems with dedicated midbass drivers and the level matching can be a bit tricky. I've also found that across a wide variety of music I occasionally feel the urge to fine tune it a bit. I have used the lpl44 with great success to address that issue as long as I knew the end user was a responsible listener! That said, given the lpl capability on the low-pass signal from the eq215ix and assuming you can teach your bro how to use it properly I don't see any downside to going with option A. Keep in mind that even if slapping him around a little doesn't set him straight you can always tune the system so that the lpl has the limit of your choosing inherently built in!

The upside you mentioned to option A is maintaining your better eq option for the midbass signal and although it is a narrow band, the excelon parametric capability from option B may still not address what you need it to. The preset center frequency options may suffice, but if you go with option A you'll have BOTH graphic AND parametric options, and this could stand to be beneficial in the mid and high ranges in addition to the bass realm.

Other than that....I must admit I lied to ya. Something you did overlook is the potential downside of relying on the volatile memory by utilizing the deck's processing. It may not arise all that often, but it can be a pain in the ass to lose your settings, especially when your brother is trying go get you to help him out over the phone when the problem comes up!

I'm assuming your sub amp is lpl capable as you alluded to that capability. Of course if it isn't you could always use the sub level control, but we could start a whole other thread describing the benefits of lpl over sub level adjustment.

So...to sum things up, given your option to use lpl on the midbass I really don't see any downside from option A as compared to option B. In contrast, there seems to be a whole lot of upside by going that route and to top it all off you said it your self that it's the easiest approach! 2XLPL44FTW!!
