View Full Version : Best 6.75" 3-way or 4-ways?

So I inherited the parents minivan and need some audio upgrades to survive driving it daily (keeping my baby safe in the garage, saved for weekends). It's a 1998 Olds Silhouette with two sets of 6.75" speakers. I will probably add a 2 channel amp in the near future.

I'd like one set of good 6.75"s for the front with good range. Doesn't have to be crazy loud, looking more for good reproduction overall. The rears don't need to have as good a range, as they are further away.

So what is your vote for really good 3-way or 4-way 6.75's? I'm looking to spend under $200 retail. I like Boston Acoustics, but not sure about this application.

Thanks,
Andy

Loading up a multi-way driver with multiple cheap tweeters does not make them sound better.

Stick with Coaxial's.(2-way)

Ok, now the speakers up front are in the bottom of the doors, so would you recommend a 2-way component system with seperate crossovers and tweeters I can mount higher in the door panels? I'm thinking I can get a pair with great sound for the front 2, then a pair with more bass emphasis for the rear set, all running off a single 2-channel amp.

Any recommendations on products? Again, the front set should have the best frequency range.

Thanks.

Don't buy 3- or 4-way speakers. Most of the triaxial or quadraxial (3 or 4 speakers in one chassis) are pure absolute 100% garbage. You'd be far better of with a good basic coaxial or component pair.

The concept of rear full-range speakers tends to suck almost as hard as quadraxial speakers- going with a nice pair of components and a simple subwoofer or two is a much better idea and will sound far better.

The reason I wanted a pair of components in the rear is for rear passengers. Being that it is a van (albeit a minivan) there is a lot of space, and I wouldn't want the only sound in the rear 2/3 of the vehicle to be thundering bass. I have no problems installing speakers that are more geared to toward base rather than highs, but I don't think I can make do with just subwoofers in the rear. Also, I wld like to retain the funcionality of the full cargo space, so that means hiding the rear speakers in the rear hatch door.

Is there a speaker set out there that is 6.75" round that can handle fairly good base and mids for $180 or so?

What would you guys put together package-wise for this? two 6.75's for mids and base in the rear, two 6.75's for mids and highs in the front, and an accompanying amp.

Having subwoofers doesn't automatically equate to "thundering bass." There are many subwoofer systems that integrate nicely and give audiophile quality sound, don't attract attention to themselves by being heard a block away, and that don't require much more than 3/4 of a cubic foot of enclosure to perfectly fill in the bottom octaves.

Reasons why rear speakers aren't the greatest idea? Having directional higher frequencies played behind you full range coaxial or even component speakers will reduce the results possible with just a nice pair up front, properly amplified and installed- you'd be surprised how nice the setup using just fronts plus a sub can sound throughout the vehicle- in a van, an SUV, a sedan or a coupe...hence the recommendation. Just because the manufacturer of your van saw fit to put rear speakers in it doesn't make it a good idea from an "SQ" aftermarket audio perspective. Type "rear fill" into the search function for endless hours of good reading on the subject and some compelling reasons not to spend good money on rear speakers- if you absolutely have to have it, use the stock speakers powered by the head unit and fade them down to the point they can't be heard up front. You won't find much in the way of aftermarket 6.75" speakers designed to put out "good" bass, but you might find some designated midbass speakers for the upper bass frequencies- they'd still be no match for a proper subwoofer though.

Good luck.

Sounds reasonable to me. I'll check it out and do some more reading tonight. I guess it works out from a financial point as well, i can spend more on the front set then. Thanks for the help and explaination.

Any thoughts on a good lower-cost amp to run these?

You could pick up a nice 4 channel amp, with the intention of using channel 1/2 to run your components, and bridging channels 3/4 to power a modest 4 ohm SVC sub...makes for an economical way to power an entire economical system.

What's your total budget going to be? Maybe a member here could point you towards an entire package that will all play nicely together. To save money, it'll be best to plan out the entire system rather than go through a series of upgrades due to evolving equipment choices ;).

I'm an engineer, I'm all about planning. If I could swing an entire system in a package, that would be optimal. However, I fgured that i could piece-meal it together from ebay for cheaper (I like high end stuff, but always looking for the lowest price for it). The problem with the sub remains though, how do I include one without sacrificing interior space in the van?

One solution may be to find a sub that is made with an especially shallow depth, then i could cut a hole in one of the side panels and wedge it in. Something like they make for pick up trucks for behind the bench seat mounting.

So if I can find something I like that works like that, great. Otherwise, I will probably go with a two channel amp, replace my head unit and just run the factory rear speakers off the head unit.

we'll see if anyone else weighs in with an idea or a product they've tried and liked. thanks all for your help so far.

Oh, budget will be about $500 total for everything. the van was free so I can't really rationalize much more money for audio upgrades.

If keeping your OEM Head Unit(redio). Here's what I'd do:
This amp, 60 watts RMS from 4-channels, and it has High Level Inputs so no expense on an LOC.

Front speaker's
Image Dynamics CTX65CS Comp's. I havn't heard them, but going by those here that have. These are a good bargain.

Read more than one good review about these, for the rear.

If you decide to go Coaxial's all around. Don't be cheap if you want it to sound good. I base these pick's on brand reputation.

Remember, the only way to really good bass, is with a sub.

Thank you for the advice, I was looking into those Polks as well. I looked all those links over, and did some price comparisons. I think i will try to shave some money off to set aside for a head unit in the future, but for now this is what I came up with:

Amp:
Is there any benefit to choosing this:

Over this?:
http://www.woofersetc.com/p6037/FXA4060--Cadence-4-Ch-200-Watt-Amplifier.htm
Would one be better to run a sub than the other? Is the RF worth the premium price? They seem pretty comparable, but one is listed as a 200w and the other a 400w. Obviously this changes based on the Ohms (2 or 4), but is there a printing or listing error?

Up Front:

I like the range and price of these, and ability to mount a tweeter up higher.

Rear:
http://www.woofersetc.com/p6137/DB651--Polk-Audio-65"-2way-Speakers.htm

I also may include a small sub in the end when I add the head unit, but for now lets focus on SQ within this price range.
