Haven't heard of dual cone recently how ever there was a company that were using 2 cones instead of 1 a few years back mainly for stregnth. A 2 way speaker has 2 distinct parts to it 1 being the main woofer the other being a small "tweeter" style driver.
In general terms the bigger the cone area the lower in the frequency range the driver can produce at the expense of the higher range. whereas a smaller speaker produces high frequencies and not much Doof. hence two way speakers most good quality 2 way units (co-axial or split) have a mid woofer and a tweeter match so that as the mid driver fades out at high freq. the tweeter kicks in where the tweeter left off to produce a larger field of sound wavew. (Note if a sub is in the system the mid should pick up where the sub driver ends)

If you mean dual voice coils this usually refers to sub speakers as they are the largest of the speakers they move alot of a air which can load the voice coil and magnet a dual voice coil speaker has 2. dual vioce coil subs are good if you have smaller amps as you can load them down and get good power to them.

Dual cone speakers have a cone that sticks out around the centre cap, you'd recongnise one if you saw it. I think the cone is supposed to help the speaker hit higher frequencies, basically they are crap compared to a 2-way co-axial speaker with an independant tweeter and woofer. Splits however have it all over both of them Smile

A good set of coaxials are better than splits, but there aren't many out there.

How do you figure that?

The whole advantage in splits is separating the woofers which need some airspace and the tweeters which are really directional and work best without things in the way. (like peoples legs in the case of a coaxial in a door)

Even the best co-axials i've seen are only able to angle the tweeters a small amount to make them work a bit better. Good for tight spots though, especially if you don't want to go to the trouble of making build outs for your speakers.

I would have to disagree with you there, a good pair of splits will always sound better as there aren't competing sounds trying to come out of the same location. You can also better position the tweeters for better sound Smile

In a split 2-way system the tweeter is nearly always mounted away from the woofer, when in reality the best location is to actually have the sound eminating from the one location. read CO-AXIAL. If the tweeter is mounted away from the woofer any staging and imaging is destoryed and needs to be taken up by focasing the sound to one point.(which involves more work that I doubt the stratties are going to do for you.)
second to this is the higher the frequency in the sound waves the more directional the sound is, the lower the frequency the harder it is to pinpoint the sound source. So as long as the tweeter is in front of the woofer ( and yes I do agree with you frank) and there is decent air space between them the mid drivers sound waves will travel around the tweeter with limited loss in quality. In a perfect world a speaker setup would be 15inch sub --> 8inch mid base --> 4 1/2 inch mid --> 1 1/2 dome tweeter with all speakers co-axial, But I'd like to see this done in a car environment Very Happy

This is a good example of what I mean sadly it doesn't come with a separate crossover. from memory Jaycar had a good example of a co-axial speaker as well.

Thats cool, what I meant mainly was that from an imaging point of view, the mounting of the tweeters is more important in terms of direction than the drivers taking care of lower frequencies.

Strathfield will never touch my car...they just seem so dodgy Smile The next stuff for my car will be most likely a set of Focal splits with the drivers mounted in custom pods in the doors and the tweeters mounted up on the dash.

"stratties" will do what ever you pay them to do.

if a customer asks me to put a tweeter on the A pillar, ill do it even though i know it will sound bad.

if you want a good sound stage, tell them, and they will ask you questions on what exactly it is that you want, and they'll do the best they can with the money you want to spend.

people that go to these places with no money and want the world are just annoying...

if you know what you want and are prepared to spend the money they will help you out as much as they can because they value good non-annoying customers...

my 2 cents

sorry to sound like im whinging but i take it personally...

i've worked for "stratties" for almost 4 years and when people say they are dodgy it shits me.

if you are going to say that you should explain the particular circumstances that brings you to that assumption or at least what store in particular it was that was dodgy...

yes i've heard stories of people doing dodgy shit but i know for a fact that all the fitters at my store will do any given job properly, if there was a customer to come back to fix a problem %95 of the time it would be product failure.

just getting my point across.

Thats the problems with any chain of stores, it all comes down to the people working for the particular store.
I just got sick of that sort of place where they're always trying to sell something to you, personally I'm not totally ignorant so I didn't feel pressured, but I've actually had them lie to me in order to make a sale...and thats wrong Smile

They can't be too dodgy in every store though, mate took his car there and in their workshop they had an NSX Smile

I just buy stuff from there because its a decent price, who cares if its not the latest or greatest.

A mate of mine didn't have a soldering iron and went the twist and tape job for his entire stereo install. Soooo dodgey Smile the car was pretty funny on a bumpy road though, if you can stand massive amounts of skipping that is Smile

I did a conversion whilst at uni.......now i am pov Smile

But this setup has some BOSE equiliser/amp type thing installed in a comparment in the boot with a bizillion wires running into the thing.

I cant find any info about the sucker on the net.......But im guessing my wiring issues lies somewhere amongst that bunch of wires inthe compartment.

Time to run some decent speaker cable and avoid all the bottlenecks!

I believe "stratties" are dodgy, well in my area anyway. Got an alarm + immobiliser put in. Very dodgy, no boot alarm even though it was a "full car alarm", booked it in and taken it back there twice to get them to put one in, but the mercury switch they ordered didnt turn up, then the second time it broke. Also very dodgy wiring, immobiliser caused start up problems every now and then, really annoying. Solder dripped all over my car mats(lucky they were cheap), chipped my dash when installing alarm light and no casing or anything around any wires. Thats dodgy if you ask me Confused

I would never get anything done there again, for me I would have rathered to spend the extra money and get it done properly somewhere else.

I usually buy all my gear from my gf's uncle, or from my local Car Stereo City. I go back because he always tells it straight, never tries to pressure me, always gives me advice even if I'm not going to buy it then and there and gives me a guild discount even though technically his store doesn't honour it. Now THATS how you get repeat custom.

I had 1 and 1 only install from stratties basically bourght a head unit, stacker, Kenwood 6 inch dual mag spilts front, co-axial rear to be wired to an amp already installed in the car.
I specifically asked for custom work to the doors to achieve good imaging/staging and was charged $650 for installation.
Upon recieving the car 6 days later the front and rear speakers were in the factory location and the tweeters were mounted in the corners of the front windscreen. I was assured that the staging was good and the speakers had been tilted up towards the centre of the cabin. They played the radio and showed me how and where they mounted the stacker and how to use it. and I drove home. upon arriving home I loaded up the stacker tuned the radio and headed to Cronulla for a bit of a cruise. get there go to put the windows down... they don't work. power windows weren't reconnected. Went home had a look at the doors and the wiring for the speakers had been put through newly drilled holes just under the plastic pipe where the factory loom goes through with no grommets for protection I wasn't impressed by that. I pulled off the door trims to fix the problem and noticed the speakers had been wired out of phase on the drivers side and the tweeter wasn't connected on the passenger side. Started to think I was ripped off I took the car back down to stratties and showed them the problem. I could keep telling the story but I'll keep it short by saying in the end it turns out that the speakers were installed in the stock locations with no custom work what so ever, one of the tweeters wasn't connected, one of the front speakers and both the rear speakers were wired out of phase, the power window switches weren't reconnected, the head unit that was installed was the wrong unit (one down from the one I ordered) and the speakers were wired to the head unit not the amp as I specified and there was a feed back problem. All this for $650 WOW I'll be back again[/SARCASIM]
In the end the install was fixed and I was charged $180 for the install but I'm sorry that's enough of a reason not to go back.
Since then I've started doing installs with my brother into cars and most of the work is sorting out shorts and feedback form the same store.
I don't mean this as a generalisation as I've seen the work that comes out of the Concord stroe and that is quality work (and if pioneer use them to fitout there demo cars they must be doing somthing right) But the store I went to Rolling Eyes

good with discounts, good with installs.

not the cheapest around (although I have friends who get BIG discounts), but they do an awesome job, especially on mid-high range stuff.

from what I've heard they were aiming at the brands that SCR don't carry ie Alpine, Clarion and the more High end brands
No Sanaui sort of stuff. The salespeople seem to know what they are talking about as well. Havent yet bourght anything from there.

I've got a friend who had an alarm installed at Strathfield and half the alarm's features were not connected... It was as if they took the alarm out of the packet, hooked up the flashing LED and the "woop woop" noise and decided it was done. Very dodgy.

And in Melbourne there's a joint called Central Car Audio that are not the cheapest store around but the guys that work there really know what they are talking about. They are interested in creating quality sound systems not just sales. They deal in Alpine, Blaupunkt, VDO Dayton, Eclipse. Free plug for being good to customers. Smile

remember the part where i said to name the store you went to?

nobody has.

if you do i might be able to get the fitter sacked. nobody wants dodgy people working for them or on their car.

when i do an alarm i hook up all the features... unless there is a problem with the car that would stop me from doing so, in which case i would tell the customer about it and recomend they see an auto elec. then if they were to come back i would hook it up...

no matter where you go if there is something broken on your car when you get it back that wasnt broken when you droped it off that place is responsible to fix it.

i know sales people can be pushy and that shits me to... theres nothing worse than feeling obliged to buy something you dont want.

as for the custom work, not all strathfield stores have custom fitters... if you were specific enough with your request and they didnt carry out your instructions why did you pay? you should have said " this is not what i asked for".

you definatly should not have been forced to pay more to get it fixed. no matter what the problem was.

and the power window plug is a easy mistake to make... i must admit i've forgotten it once or twice! Rolling Eyes but its easy to see why it was an inconvenience for you.

i know most of the fitters at the concord store and yes they are good... they have to be coz thats the head office!
john the custom fitter is one of the best.

that story about lifestyles to an extent is wrong.
i dont know about the dick smith bit but the bit about the owner of lifestyles being the old owner of strathfield is wrong.
yes he worked for strathfield but he didnt own it...
almost all of the sales team down at the parra lifestyle store are ex "stratties" workers.

anything else?
