I need your help! Im looking at a couple of different speakers and I need some serious educating. Im looking into it as we speak, but perhaps I can get some extra light on the subject and maybe some personal experience and opinion as well.

Im looking for 5.25 components for my FD, and Im looking at the Zapco I-Force line and the Infinity 50.7cs'.

Anyone have any info on those two sets?

Oh, the major question I have is this... Can someone possibly break down the technical specs for me?

Response Bandwidth 55 - 25000 Hz
Sensitivity 94 dB
Crossover Frequency 3500Hz

Each crossover features an 18dB/octave, 3.5kHz high-pass network for the tweeter and an 18dB/octave, 3.5kHz low-pass network for the woofer.

What does any of that mean? what should I look for and such?

Ok, thanks in advance! Im off to try to find some of that info on my own!

Uhh... It's been around for decades now. You've never heard if it because you're not "car speaker smart".

They are suposed to be a really good brand.

frequency response is what frequencies the speakers can reproduce. even tho human hearing range is 20hz-20khz we still need speakers to produce even higher frequencies to produces OVERTONES. overtones are when frequencies combine to make 1 frequency IE, 51khz and 50khz produces a 1khz tone.

cross over frequency decides at what frequency the speaker produces sine waves(frequencies). the tweeter has its own cross over, and so does the mid. tweeter plays higher frequencies, woofer plays middle frequencies. im not 100% sure on the 18dB octave part.

check out CDT. since you own an FD you must have the money

PM me if you have other questions. also Icemark knows a lot of car audio shizit.

I did a some research and it seems to me that the infinity speakers are a good safe bet for my system. I was thinking those 50.7cs componets and some 2 way 6 by 8's for behind the seat.

Any naysayers?

jonesfromindia

in the rears get coaxials. fronts get components. thats my 2 cents.

but how will you be powering these? and what is your price range?

I have a Pioneer Premier Deh-p960mp deck, A Clarion AXP 4240 4 channel 60 per amp, An Orion Hcca 225 Amp for the one Infinity Sub im going to run.

Thats my thinking. infinity 50.7cs in the front, 6 by 8 behind, and both of those powered by the clarion, sub in the trunk.

I was hoping to be reasonalbe hence the infinity line. I both sets of speakers and the sub for about 350 bucks. That seemed reasonable to me.

If you have sugestions, shoot. Im willing to listen and look at other options. Nothing is etched in stone here.

teenwolf1393

does it make u feel good to talk trash to people that dont know something as unimportant as a single speaker brand. go crash ur escort.

jonesfromindia

honestly a good "bang for your buck" speaker would be some alpine type s'...i mean they arent the greatest. but cheap and reliable. but some infinity lines are better. you could even go type-r. infinity subs are total BS IMO. if you want sound quality at a good price check out...

www.imagedynamicsusa.com

their IDq is a great line. IDmax's get decent loud, but their subs and speakers sound amazing. their speakers might be out of your budget.

but i have a ID12v.3D2 and i absolutely love it. sounds great, and gives me extra low end at a reasonable volume.

I'd go Infinity. +I love your avatar. "I rule in favor of, BIG AMERICAN PARTIE!!"

Your post is right except for that. A crossover is a type of line filter, in this case, a high pass filter. 3500Hz is the frequency where it starts. Below 3500Hz attenuation begins (your music gets softer), the 18dB/octave means that for every octave below 3500Hz, the output wave is 18dB quieter or about 6 times more quiet.
The number given for speaker sensitivity is pretty useless w/o an input signal value since sensitivity is the sound level produced by a given input. It could be 94dB at 10watts or 94dB at .001watts, without knowing the input power it's hard to tell what they mean.

Hope that helped.

I have Focal 165V1's in the front of my car. I couldn't be happier....really, they are incredible!
http://sonicelectronix.com/item_6271_Focal+165+V1.html

Seriously, these could be your only speakers in your car and you would only need a sub to be complete!

actionhank

That does help. thank you wankelfan. The one reason I want the Infinity Sub is because of the fact I can run the sub at 1 ohm. I want to run one sub and run it at 1 ohm and this is probably the best way to do it. If you guys have other sugestions, Im all ears though.

Im finding the Infinity Kappa line for about $100 a pair so Im ok with paying that.

Also, should I stay simple and go with 5.25 and 6 by 8s or should I put the 6.5 and 6 by 9s in? Any thoughts on that as well?

Anyone know much about Elemental Design?

http://www.edesignaudio.com/edv2/index.php

I've heard good stuff about them.

Those specs essentially mean nothing. The one thing that does matter is the crossover points and slopes ... it's very important in a car to cross over to the tweeter as low as possible, because the midrange will beam above 2000hz ... which will mean a big suckout in the response curve unless it's pointed directly at your ears, and that ain't happening in an FD or any RX-7. Focal stuff I love, but it has the same problem - the TN47 needs a 3000hz crossover at least, the TN52 can go a bit lower though.

My answer is going to be to use a standard flange tweeter in my next car install - not a small flange Neo magnet tweeter. I'll probably use the Dayton RS28a which can be crossed as low as 1200hz.

My point is unless you can design your own crossover, or am actively crossing over, shop for something that has a crossover point at 2500hz or lower.

Elemental makes some nice stuff too ...

none of that really matters if your going to be using the passive crossovers. Any specific budget? Personally i have been around the block and back, been through focal, morel, dyn's, genesis, rainbow etc. My personal choice is rainbow and that is what is going in my fd, they have different price points depending what you want to spend. I am getting the cs230 (5.25 for the front) profi line which is around 500 with my discount and cs 265( 6.5 speaker for the rear) for 550 with my discount. Nothing will beat these speakers at that price point other than a DIY set-up which will require you to go active and buy more amplifiers and is a major pain in the *** your first time; you also more than likely wont get it to sound right and it will take awhile unless you get a pro to help you out.

actionhank

well, Its not that I cant spend $400+ on speakers, I guess I just dont see the over all need.

Ive never really been able to tell the little differences between speakers so unless I had them in front of me so I could try to tell the difference between speakers, I dont know If I would be albe to really tell the difference between pretty good speakers and really good speakers.

Im not a super sound person, but I like to have a good sound coming from my car.

Basicly, I dont think I could warrant spending the extra grand, at least, on speakers when I dont feel Ill be able to really tell the difference. Like I said, if both set ups were in front of me to hear so I could compare, alright, but if I dont know what Im missing...

Also, from what I have seen, the infinity line hasnt exactly been getting terrible reviews.

purerx7

iTrader: (61)

depends...take for example the polk sr6500's, they have gotten the best reviews i have ever seen, caraudiomag gave them their highest rating over some much much more expensive speakers. I couldnt begin to tell you how excited i was to audition them. Had a buddy install them in his car and break them in, finally got around listening to them and i was really unimpressed, even with playing with his EQ for a little bit they still did not sound that good. So dont make great reviews the only judgment for buying them, its only my opinion that you cant beat rainbow speakers at their price point, hell you could get the rainbow slc for mid 200's and you would be more than happy with them.
Your best bet is to go out and audition the speakers your interested in and find the ones that sound best to YOU. Some people LOVE focal speakers, but they are to bright and i cant stand them, except for their BE line. Anyways my point is ALWAYS audition before you buy if possible, and preferably in a car not a sound board.

actionhank

That is great advice. You make a great point. Ill have to try to find somewhere to listen to them.

I have two elemental designs 6.5" subs in my rear deck. I have them in two .3 cubit ft sealed enclosures and they are getting 150RMS a piece....They sound awesome but I think im going to port them for a little more output, that is all I need!

illmattik

i concur wit rainbows. Probubly the best around. i got them in ma FD! YAY!

Yes, rainbows are VERY nice too. That is the only thing that could ever get me away from my Focals!
