Home audio drivers vs. car audio drivers



Just kinda curious,

Drivers seem to be specifically made for either Home Audio or Car Audio.

What exactly is the criteria that seperates these>

I see alot of good speaker manufacturers making home audio AND car drivers. Focal, Infinity, ETC, ETC.

I hear alot of problems from DIY'ers about matching tweeters and midrange drivers, was curious if anybody ever messed around and tried building a set of 2 way speakers using infinitys $200 Reference Kappa Component sets.

Is there an actualy difference between car audio and home audio? Is there a different approach to design? Ive seen car audio drivers that run in the thousands of dollars, i know enough about car audio to know that they put ever bit as much of engineering in those products.

or is it basically the fact that most car audio speakers run at 4 ohms while home audio speakers run at 8ohms?

Ignorance is bliss,I'm told. But I know from personal experience, back around '96-'97 Soundstream made an amp that was designed by Krell and to their standards. I took the amp apart once to see if it was up to high standards of home audio and beleive me, it was built to a pretty darn high standard, Looked to beat out the mid-fi equiptment we have on hand today. It would run all day on a one ohm load. I ran two channels of it bridged into a 2 ohm load for almost 2 years and never had a problem or any over heating. It was one a thousand made. But still, your statement is way off.

Their were other companies that built some high quality car audio, also.

Of course $1800 for a car audio amp, or any amp is a bunch of money. But to make the statement that 12 volt amps are junk, is not a smart statement. But, if you buy from Tweeter or other appliance stores you most likely will get junk car audio equiptment.

I can't imagine 'car audio' has all gone to the dogs since I messed with it.

Btw, in the late 80's Bob Carver and one of the hi-end mags did some comparisons of amps (12v vs. 110v) with a pr. of Maggie's and the 12 volt amps didn't do too badly. Held their own in some respects. I remember back in the mid-late 90's Wes Philips had a 'car audio' column in Stereophile every 3 months . I doubt they would have given 'car audio' an editotial spot if it wasn't worth a darn or if it wwas junk.
I read and reread the 'Speaker Design Cookbook 10 years ago and reread it 'til I understood it.

For anyone that believe's you can't get great tuneful bass out of subs design toward cars, then you don't or won't understand the Cookbook.

I've forgottern more on the subject of subs in a vehecle than most people will ever know. Lets not forget, the driver is only part of the equation. The cabinet and the interior of the auto also have to be taken into consideration, if you really want topnotch bass in a 4 wheeler.

But the bs you find in car audio can be found from manufacturers of home audio.

Example that pops in my mind every time I see it, is the Sunfire subs that claim 2400 watts of amp output. Not happening in that product. Very simple reason. A 15 amp breaker will blow long before you achieve 2400 watts.

I have forgotten the formula, as I mentioned earlier I've forgotten a lot of this stuff, but if I recall correctly, about 1500-1800 watts is the max draw on a 15 amp circuit.

There's as much deceptive advertising in home audio as car audio.

CDC, you can't change the laws of physics. A vented box can NOT give the same Q, QTS, of a sealed designed. Read the book. Please.
