I've been doing a lot of reading especially on tweeter placement once i get my new components in. currently, i have 2 sets of tweets (one set on the dash and the other in my sail panels) I swtich from one set to the other when i want to listen to music outside and inside the car. I do not want to go with 2 sets of tweeters this time around. for 2 reasons... 1. Focal tweeters are hella expensive and i can't afford another pair 2. I just don't want to go that route anymore. I would love to put the tweets in the sail panels to make it look neater but after reading a lot in DIYMA, it's not very good for staging. It's a long story but even putting the tweets on axis still wouldn't have as good was sound then on the dash.. Now, one thing or problem i may face is that if i put them on the dash again or somewhere on the A-pillar, my deck doesn't have time alignment, only speaker distance meaning, my deck is not a SQ deck. So if i go with various places on the dash or A-pillar the timing may be off because they'll be far from the midbass. Here's the catch, i've tried putting on my tweeters in the sails when i'm inside and i obviously don't have the best ear but it sounds pretty damn good. the tweets on my dash are a bit more tamed and seem to have a bit more depth though.. Any input on what i should do?
get this, i also ready that sometimes for staging purposes you can also test your speakers out of phase. sometimes if you run one side out of phase, either tweeter or mids the sound could be better. Anybody ever heard of this being done?
ive read about if your tweets are far from the mid you can wire them out of phase with the mid. go with what sounds the best to your ear. inside.
ok, look wise i want to put them in the sail panels and honestly i like the sound better though but i don't have an ear for SQ so i guess it would be okay like that. once my focal get to me i'm going to try the phasing thingy to see if i can get better sound that way. Thanks for the input. Oh, by the way. I picked up a a set of MCSQ6.5 - Memphis MClass 6.5" Component Speakers. Got them for only $50 shipped... thinking of using them for rear fill or put in the the wifey's car or sell them if someone is interested in them locally. Have you heard anything about them?
The front speakers need to be in phase. The tweeters can be out of phase but that may not be necessary. Tweeters are directional and draw your attension to them. For that reason, I like them pointed away from me. For that reason I like the dash location. If its possible, you need an 18dB per octave crossover on the tweeter crossed at 5000 Hz. The additional audio will wake up the tweeter. The 18 dB per octave crossover will make the tweeter 90-degrees or 270-degrees out of phase. Being slightly out of phase will make them a little less directional Can you get a larger speaker in the dash??? A 3-1/2 or a 4-inch. Crossed over around 800 Hz. A simple capacitor around 47 micro farad is all you would need. The results should be pretty good. Something to think about
so Ranger, you like your tweeters off axis? i was thinking of putting my tweeters on the sail panels off axis (facing each other) and not directed at me. 18dB per octave crossover on the tweeter crossed at 5000 Hz? I have no idea what this means. I'm just running passive crossovers so i'm not running active in any way shape or form. I really have no idea what a 18db octave crossover is. I really can't add any speakers in the dash. I don't want to rip up my dash in my Expedition and there isn't any place for a 3" or even a 4" speaker. Can you shed a little light on crossing over the tweeter a bit more? I just want to get the best sound but i don't want the tweeter screaming in my ear. My head unit (JVC KDAVX-2) is just pretty simple. it has no time alignment on it. It only has speaker distances on it.
Sail panels are fine. And I am taking about passive crossovers. Most crossovers that come with tweeters are 12dB per octave. This means that it can be hooked up In-Phase or 180-dregees out-of-phase. Hook them up both ways, let your ears be the judge. You know what you want.
oh, ok.. got it. I'll toy around with it with my DLS for now since i'm still waiting for my other components. thanks for the information ranger. VERY helpful.
Ranger, one last question... I have speaker distance settings on my deck. Is that the same as time alignment?
hey CC thats what i got. i think you liked it didnt you..lol. my dash at the time was crossed over fairly high. like maybe 600ish or more. now their a lil bit lower since my 4ch died but their still around 200 and up.maybe more since im using my amps xover too. it seemed to help.
Yeah, i do remember that's what you have pedro and it sounds great! I just can't tear up my dash to do that... Pedro, i did a lot of reading on time alignment adjustments... You may want to try it out to see if your sound gets any better.. This is what i found out... Measure your sub (from the cone) to your forehead in your driving position... Then take a measurement from each speaker that you can time align the same way to your forehead.. Then subtract your furthest speaker (sub) from the other speakers and that's the distance you want them. ex. sub is 205 cm away from your center forehead. left front speaker is 50cm away from your forehead. so 205-50 = 155cm is the distance for your front left speaker... Not sure if your deck does it by cm or inches but you get the idea. Try it out and see how it works.
i copied and pasted this from another forum to help you out if your interested with toying around with your deck: A = (B - C) / 34 A: Delay time (ms) B: Distance from listening position to furthest speaker (cm) (your sub) C: Distance from listening position to the speaker to be adjusted (cm) For example... Example: If you're in the drivers seat, B: right rear speaker 100cm C: front left speaker 50cm Delay time = 100 cm - 50 cm / 34 = 1.47ms - figure 1.5ms. You need to do this for every speaker independently. You may be surprised; in some cars, your rear speakers are closer to your head than your front speakers are, and you would actually delay them more than your fronts. Be prepared to tweak it a bit, as you may not sit exactly in the same spot when driving around. THIS EXPLAINS IT IF YOUR TIME ALIGNMENT IS IN MS.
