Component Speaker Question
How close can you put the crossover to the midrange driver magnet? I have a set of 165W2 Focal speakers and have found a neat place to mount them on the back of the MDF holding the midrange driver. I noticed when I was terminating the leads that the screws were a bit magnitized. The crossover is about 2-6 inches from the driver magnet. Is this problem? Will it create or make funny noises or operate improperly? :confused:

Re: Component Speaker Question (Randy K)
The coil in the passive crossover will actually make up its own inductive field having no real bearing on each other. The speaker magnet is a polarized field, while the air coil is an alternating field. There won't be any noticable effects, other then the screws, which although seems strange, isn't out of the ordinary for close proximity.
Just make sure the crossover is sealed from any water intrusion. :cheers:

Re: Component Speaker Question (Randy K)
hmmm...very interesting because I just got done cutting out my mounting plates for my 165w's. I was planning on sticking the crossovers to the inside of the door close to where the speakers mount but I think i might like your idea better.
Are you going to flush mount the tweeters in the mdf for use the pods?
Any pics would be great.
Luke :D

Re: Component Speaker Question (Randy K)
DON'T put the focals crossovers in the door.. after about a week or so Focal crossovers start rattling pretty bad... I had to sit mine on a couple layers of foam with the tops off in my amp rack to get them to be somewhat quiet. Plus, you can't play with the crossover settings if you can't access them easily. :D

Re: Component Speaker Question (Nevermind)
where else would you put them in a C5? I have my car all apart and I had all intentions of putting them in the door, but i've never heard anyone else say this before.

Re: Component Speaker Question (Randy K)
The bits and pieces on the 165W xover rattle. That's obviously not an opinion. "they suck" is an opinion.
Both of them did it.
If you put the 165W crossovers on the baffle with the Speakers, it's likely that in a few weeks you'll start hearing a little rattle with your bass.
I'm not quite sure what's in them that is rattling. I haven't torn them down and played with them.
They didn't at first. After some time though.... They rattled on rough road. They rattled when the sub hit. they rattled with the 165w played certain tones...
Maye they wouldn't rattle if you put silicone around the pcb, or on the parts, or stuffed it with polyfill so tight you can barely get the top on em.. who knows?

Re: Component Speaker Question (Nevermind)
Nevermind,
Is the rattle a physical rattle like something inside the crossover is loose or is it a speaker rattle like something electrical is broke and the speaker isn't working right?
about the "opinion" thing. I'm not dissing you. I've just got burned a few times from people that act like they're experts only to findout they don't no squat about what there talking about. not that you don't know what your talking about. I just wanted clearify you expierence.

Re: Component Speaker Question (Randy K)
Regarding the rattling on the crossover. I have the crossover from my 165k2's that I am going to install in my hand. The cover on the crossover is rattling along with the circuit board inside. I am sure, the rattling can be stopped prior to install. Maybe some silicone or a couple of drops of glue on the circuit board mounts. As for the cover, mine is going to be wrapped with a panduit and installed in the door, end of problem.

Re: Component Speaker Question (baldie)
Yeah, the covers rattled too! I do think its the PCB rattling... if it was secured better to the body,. maybe it wouldnt rattle... if I didnt have mine buried I'd tear them down for you.

Re: Component Speaker Question (Randy K)
I just pulled the crossover apart. Everything is tight, except for what I mentioned earlier, the circuit board and the cover. Silicone or glue, whatever you prefer. I am going to do some plastic cement on the inside for the circuit board(I can exacto it out later if I need to, should be never), maybe some rubber tape all the way aroung the outside of the case. This will stop the rattle and give me a little dampening effect by using the tape.

Re: Component Speaker Question (baldie)
a permanate magnet close to an oscillating coil will change the coils inductance value. Not that this would cause harm, but it would change the original designed crossover point.... which may cause exceptional speakers to loose their carefully engineered sound qualities.

Re: Component Speaker Question (Mike Mercury)
I like the idea of mounting the crossover where you are, I'd like to hear some more opinions on whether being that close to the magnet will have bad effects. I can't remember offhand (I'm not at home) which end of the crossover the coils are in. If I remember correctly they are in the fat end of the crossover which would be farthest away from the speaker magnet. If this was the case then they would be probably far enough away to not cause problems.
Randy, does your tweeter have plenty of clearance in the door panel mounted like that? Just curious since I'm getting ready to be dealing with the exact same stuff. Figured I'd let you be the guinea pig for me :D

About the magnetic field, I have already set everything up to install them this way. I don't really want to go back just yet. I will finish hooking everything up (hopfully this weekend) and let you guys know how it worked. If theres a problem I'll just have to take it all apart and move the crossovers. :( It appears that I will have to take the door speakers apart once more any way to fix the crossover rattle. We'll see.

Re: Component Speaker Question (Randy K)
Hopefully yours won't rattle. I'm a rattle jinx myself.. even my new toyota rattles. :D
Just leave the covers off in the doors to avoid the rattly cover problem... As long as they are protected from moisture you're ok
have you already listened to the set in the car? Do that before you assemble the doors.. you may want to run the tweeter down a few DB from the passive crossover after listening to it for a while..

Re: Component Speaker Question (Nevermind)
I read that the crossovers would be touching the speaker magnets. Heck... any distance... even a few inches will lessen any impact.
Chances your ears won't hear any difference anyways. Only test equipment and uppity audiophiles can detect a minor shift in crossover frequencies :)

Re: Component Speaker Question (Mike Mercury)
It also depends on how the coils are oriented in the crossover. If the axis of the coil is oriented in the same direction as the axis of the speaker, then the inductance value will change. If the axis of the coil is in the plane that is perpendicular to the axis of the speaker, then the magnetic field will have no effect on the coil's inductance value.
