Im about to replace my 4x6 and 6 3/4 speakers. i could use 6 1/2 speakers in place of the 6 3/4 with an adapter, but anyway what company makes the best speakers, but more importantly whose are the most affordable? Planned on buying Sony 6 1/2 and maybe audiobahn or infinity 4x6. help me out please.

Cdt...

"what company makes the best speakers"
"but more importantly whose are the most affordable"

You need to make up your mind, because there are VERY different answers to each of these questions, and Sony, Audiobahn, and Infinity are no where near the top in either category.

of course there is a difference between the two, but as a 16 year old with a job at a fast food resturant i have to reach some sort of compromise between the two. could you give me some suggestions of speakers that are good, but affordable.thanks

I only buy Diamond Audio

sr20, why don't you think Infinity should not be anywhere near the top?
I'm running Infinity componets and I gotta tell you they're up there f?cking with Boston, and I even think they got Alpine on smash.

MB Quart and Polk are two more good ones...

i duno about mb quartz and infinity.. both their tweeters sound horribly harsh at high volumes.. but for speakers i would pick maybe.. adire, cdt, jl, alpine (type x), focal, rainbow, scanspeak, seas.. and yea..

cdt, boston, focal.................
but since u cant afford those than i would have to disagree w/ some people and say infiniti. they r very cheap and r good quality. maybe thats just me though.....wuts your price range?

CDTs are cheap for coaxs. 30 dollars a pair.
Get 6.5"s and 4"s at www.thezeb.com (http://www.thezeb.com) Get an adapter elsewhere if you need one

i think ^he's^ go it down, but i dunno if you could afford focal or rainbow or scan-speak, look at the alpine coaxials those are nice, i haven't heard the cdt coaxials, but i'd assume for 30 dollards that they are the best in that price range....

I'd like to be in the price range of $75 per pair...but if you say the $30 ones are good i guess ill just get those, if there are better around my range please let me know.

well thats basicall 150$ in all, are the 6 3/4's up front? if so i'd recomend some infinity refernce components, and the if the backs are 4x6's, how about some infinity plates, that'll do......

bose makes the best STOCK speakers...period

bose makes the worst stock speakers... Bose are impossible to work around for aftermarket speakers with a stock headunit. They use ****ty speakers and put them in a special enclosure to force the most out of the worst. Sr20 will follow up if you need more. CDTs, 4" and 6.5". Inifinitys will not beat them, especially with the cost.

:eek: They make speakers that cheap? If they do, your stock ones probably sound better unless they are blown.

Dayna, you live in the off topic area, when you actually go to a real car audio place, then you can make fun of some of the best speakers that will beat those diamond audio speakers. Btw, nice to see you getting in to the audio section.

huh? I wasnt making fun of anything... I seriously had no clue they make speakers for $30.
And I dont "live" in the off topic area. I go other places too.

Just the only place, I see you...

You just came off a bit strong with the blown stock speakers sound better than that thing

Read it again... I said stock ones "probabaly" sound better than $30 speakers.... UNLESS they are blown... Get it ;)

Sorry if I offened you or your knowledge.

No I don't care really. Have a fun day

bose makes the best STOCK speakers...period

i'm gonna have to disagree, volkswagon's stock speakers whoever makes them i believe are the best stock speakers, a guy won the sq class of a competition with his stock volkswagon speakers amped........

retardedly bright midrange and tweets (if you have to flinch whenever a chick takes the mic, something is wrong), very very poor low frequency response, not spectacular in imaging, clarity, or detail. They really have nothing going for them....Alpines are decent, but nowhere near the top (except for the F1, but those aren't even Alpine, those are Scanspeak), Boston is good but it all depends on what model you're looking at, MB Quart is again very bright but they do have good detail, and I'll never run Polk, but from what I hear some of their users are somewhat happy with them....

aznxthuggie's got the right idea, but you won't find any of those in your price range. Like I said before, "the best" and "best value" have totally different lists going for them, I doubt there's one brand that can jump the gap except for maybe CDT or Focal.

bose makes the best STOCK speakers...period


According to the ignorant maybe. For people who don't know better, the drastic peaks and dips in the response make it sound more powerful than it really is. Their car systems sound exactly like their home systems to me, and that's nothing to be proud of. They might be better than the base sound system that comes stock on the car, but for the $1000-1500 that it costs for the Bose upgrade you can do so much better it's not even funny.

Holy sh?t It sounds like Infinity's are notorious for super bright tweets, and all this time I just thought it was just their freq. response to my car. It's all good though 'cause I got them routed via a parametric EQ.

how pioneer speakers the "rev" line are they any good???? I hear they can take 400watts max power to each speaker

First thing you said that was wrong is you even bothered bringing in a max rating. Secondly, how much power a speaker can handle shows nothing about how good it is. Their are speakers that will do 200watts or more rms, but they rate them at 150 because HOLY cow, 100 is loud enough to each speaker for me. Oh and Pioneer sucks for the "best speaker" area. Not even the best deal on speakers either.

Thanks for all the suggestions, ive decided to get infinity 4x6's, but so far i cant find any 6 1/2 brands yall suggested. They are so expensive, but the cdt $30 that were suggested are stock replacement i think, and i was wondering if there was some sort of difference between them and coaxials. If you have sites with low priced good speakers, please let me know.

calm down tiger!! im new to car audio to a certin extent I dont know much about speakers.... so more power does not mean it will be a better speaker thats something new I learned what makes a good speaker a good speaker???

I don't really know it well enough to get into all the details... Sr20 may know... this is a question for an audio oriented forum

i think this is

he means an entire forum...not just a section

Cro is right

Hard to tell just by specs...if you want good midbass response look for a low Fs and high Xmax (how low and how high all depend on your price range). If you want good, clear midrange try and find a frequency response graph, and make sure the off-axis response for the mid is pretty flat up to the crossover point (this is assuming they're going in the doors). If you like soft highs try to find something with a silk dome tweet, if you like harsh highs try to find something with a metal dome tweet. Make sure the crossover point is about a full octave above the Fs for the tweet, this will help with reliability and it will help keep your highs smooth and distortion-free. Um....there's a bunch more that I don't know, the big thing is just to listen to people's opinions on the speakers and see what you can find. Try to find a review of a speaker that looks like it fits what you want, like if you want soft highs and someone says it has harsh highs, then stop looking at that set right then because you'll never be happy with it. And whatever you do, DEADEN YOUR DOORS! A $150 set of components with $50 of deadening will sound worlds better than a $200 set of components, deadening is worth its weight in gold when it comes to doors. As for what not to look for....power ratings (especially peak), frequency response (like 60-20khz or 30-80khz, or whatever), and efficiency (you can use it to compare between different models from the same brand, like type-s vs type-r, but never use it to compare 2 different brands together like alpine vs pioneer) are all specs that you can completely ignore, they're just like THD and peak power ratings on amps, completely worthless.

All this being said, you really won't have many choices in the price range you're looking in ($30 sets of speakers aren't exactly high-end). You aren't going to have the selection that will let you pick sets with better off-axis response or midbass...you're going to be limited to just a few sets and then you just close your eyes and point to one and get it, there isn't much of a difference between speakers that cheap. This explanation was mostly geared to other people curious about what to look for in a speaker.

Price range i am looking at is $75 per pair. still not really high-end, but more than $30 ( i guess you might have thought i meant that was my price range).anyway, i would appreciate suggestions for speakers in my price range and maybe some sights where they can be found.and are sound dampeners really that good? and are they really only worth the money for door ones, or worth it for rear pillar speakers?

to say thd ratings are worthless is bullsh?t...high fidelity is directly related to THD, as a matter of fact their whole concepts define each other

ok, my new speaker has .00005 thd... Right there is why it is worthless. They have no way to prove it, so you have to go by other things. Quite often thd is falsified

would it be better to get components systems or full range speakers??

full range speakers... meaning coaxs?

If you have an amp get components. If you dont have an amp get coaxs

to say thd ratings are worthless is bullsh?t...high fidelity is directly related to THD, as a matter of fact their whole concepts define each other


Anything under ~1% THD on highs and ~10% THD on subs is completely, 100% inaudible. Now if you can't hear anything under 1%, wtf is the point in picking component A based on a .002% THD instead of component B with .003% THD? You'll never find anything with >1% THD, so there's no point in using it to compare. It's like the power ratings on headunits, people out there pick a headunit based solely on the fact that it puts out 22rms instead of their other choice that puts out 20rms. They think that more power means it's better, but that's a .4dB difference! Not even God himself could hear that, so using it to compare is retarded.

And like 'bane said, THD can be falsified, just like frequency response and efficiency.

O.k, here's the thing about distortion;

1.) you send a signal into your equipment
2.) on the output, you separate your original signal
3.) anything left over, (noise, hum, distortion, etc...) that was not a part of your original signal is BULLSH?T.

This is where you get your specs. for distortion (THD+N technical term). Yes it is true some distortion can become masked because it's harmonically in tune or the total system volume is just too low, but it's constantly changing. This means that for every different freq. at every diferent volume level distortion is going to be either, harmonically masked (even) or audible (odd). So depending on your listening volume and how much distortion your equipment threw into the signal flow, it can be heard at certain freq. with percentages as small as 0.1% This is why it is commonly offered to consumers as a comparison tool. Just make sure it's not a half spec. like:
THD = 0.0001%
make sure it's something like:
0.1% THD was measured at 20hz - 20khz +4dB

i think Boston Acoustics fuckin rock. a pair of their 4" has outperformed every larger size i have ever heard.

I still think it is worthless. I have heard that before. I have heard speakers with the same rating thd, and I can tell you one sounds way better than the other. thd is very useless when you start buying proper equipment

we all seem to lie

Even .1% is higher than you're ever going to see on even the crappiest of equipment, and regardless, they're STILL falsified. No matter what number the company puts there it can't be trusted, just like frequency response. Besides, how many companies actually rated their THD at "0.1% THD was measured at 20hz - 20khz +4dB"? I don't think I've ever seen that, and I look at the specs for some of the most high-end equipment nearly every day. Even if you COULD find a company that did that, it would mean nothing for 4 reasons:
1 - no other company is going to do it, so you have no basis for a comparison
2 - once you add in a 20ft rca run through a bunch of different electromagnetic fields, that .01% that you're bickering about between 2 pieces of equipment is moot.
3 - once you send this signal to a speaker, it adds so much distortion of its own that the tiny bit of distortion the amp added to the signal doesn't even matter
4 - once you start moving, you have so much external noise coming from other cars, tires, wind, etc that you won't even be able to hear 5% THD, no matter what the frequency or whether it's even or odd ordered harmonic distortion.

And even in light of all of this, we aren't talking about amps or headunits, we're talking about speakers. Once this speaker starts moving at all, the THD rating (along with just about every other rating) is COMPLETELY shot to shit. If you want clarity at high volumes with speakers, the xmax is one of the most important specs you could possibly look at, THD is just 100% useless.

my top five:
Boston
Infinity
MB Quart
Alpine
Polk
they all got a range of prices and quality levels. but, a hol06 you got $75 bucks to spend on speakers, there's a lot you can get for that much money. If it makes a difference to you (I think that's why you started this thread) you can just buy some, try 'em out and see if you like them. or, you can take a little time to figure out what the specs tell you about performance, audition a few pairs, you know to see if the specs hold true, and then make a choice you can ride out with

good lord, THD .... I remember the THD wars in the late 70's for home equipment. The manufacturers had everyone believing ultra low THD was the end all and be all. Unfortunately, they created extremely low THD by increasing the global feedback in the circuit - this created other problems. THD kinda blends in with the music, since you are just distrorting a harmonic - the distortion that is really more audible is TIM or transient intermodulation distortion. TIM is caused by the addition or subtraction of two or more frequencies being played - so it has NOTHING to do with the fundamental wave or any of the harmonics.

As for speakers, they are chocked full of distortion causing elements - it's just something you have to live with, since that .00000001 % THD amp is pretty worthless until you hook it up to some speakers.
