A Debate on the many different aspects of sound

Oh, and I feel that most speakers are meant to sound the way the engineers intended in a vehicle. Otherwise they would be experiencing a great amount of returns, which pisses of the customer and the retailer, not something most manufacturers would do.

I was using a fusion sub amp at first, but the subsonic filter couldn't be turned off, so I switched to a Phoenix XS-2500.
I don't blame the amp, probably a combination of the test disc, and the outputs from the deck, and the amp, all having a bit of error.
The error wasn't much either...voltage went from maybe 2.8, to 3.05 between 20 and 95 hz, or about 8% difference. It made a diference of 1 or 2 hz in the final calculation...Probably that much tolerance from one speaker to the next off the assembly line anyways.
I did the test a few times, and always came close to the specs I ended up using, so I don't think I'm out by much....we'll how it sounds see when it gets put together.
Yeah I suppose they want it to sound good in the car...especially the higher end manufacturers.
I think the mass market stuff is a bit of a race to see who can "out-brighten" each other on the Canuk Rubber display boards.
I would be most concerned about blown speakers and warranty issues, if I was designing product to sell, so I'm sure they have a fairly high Qm in most IB applications. I think that's the first criteria...correct me if I'm wrong.

But are you saying that the really nice ones that don't sizzle on the board are "not" designed for off axis response?
I've got some speakers in my board that don't sound good 'til you go so far off axis, that you're in the next room. Won't say who, but let's just say they've been known to explode.

^ You seem to follow all their suggestions without question and rely on them to validate your system design so obviously you truly feel this way [img]graemlins/dunno.gif[/img]
Although, and feel free to correct me if I have misunderstood, you support the notion that the manufacturers all design their drivers to work in some sort of enclosure even though 99.99% of them will never be installed in one. [img]graemlins/freak.gif[/img]
Personally I think the smart engineer would design coaxials for off axis response while potentially compromising on-axis smoothness but do the opposite for component tweeters and midrange drivers.
Interestingly, I remember that when the Alpine DDDrive components hit the market and sounded like poo that Alpine's excuse was they were designed for off axis response so they may be somewhat harsh in a display board.
