Really? Cause I only paid $160 for my 6x9s, and they sound great!
im just a noob so i dont know, which is why im askingthe way i have always looked at it overall is that with the oval speakers, primarily 6x9s, you generally get a higher output in the lower frequencies but i have always noticed in my setups that they seem to have a tendency to distort easier/faster than something that is circular and the reason for this would be the fact that the voice coil is round and an oval woofer attached to the circular voice coil is going to create unwanted flexing/drag at moderate to higher excursion and this flexing/drag will result in the coil heating up from having to work harder to try and keep the woofer moving linear and heat equals distortion in the end, now I'm not saying that circular speakers are exempt from this cause that would plain and simply be a lie but they are much less susceptible to the distortion as they do not exhibit the inherit linearity problems as a oval woofer. as stated before though with the large 6x9 speaker i do believe you do have an edge in mid and low frequency output, not clarity but output. just my .02
what do u guys think of this?from jl website:
"Many people mistakenly believe that an oval speaker cannot perform as well as a round one, leading to many instances of 5.25-inch speakers being installed into 5 x 7-inch openings. JL Audio's engineers have put in the time and effort to create fantastic-sounding speakers that drop into oval openings and deliver equivalent performance to our 6.5-inch (165 mm) round speaker systems... guaranteed. So, don't make the mistake of losing cone area and efficiency by stepping down to a smaller round speaker... these ovals rock."
It's packaging first way before power. Interior room has always been a desired attribute. The rear seats get mounted as far back as possible to get legroom. That is, before it cuts into headroom. What you have left is a typical almost rectangular rear shelf behind the seats.I believe 6x9's were designed by car makers due the fact back in the 50'-60's the amps they used were tubes, then early low powered transistors of only a watt or two.They needed a large efficient speaker to over come all the noise those car made.
They were first put in the center dash or console for mono and as fm stereo came in they would fit in the rear shelf.
Then Gm came out with the 4x10 to fit in the rear shelf of their Cutlass.
I dont really think they had sound quality in mind when they designed them, more like they have to fit in the car and be efficient enough to hear.
But then came the late 70's and early 80's with booster EQ's and Dolby tape decks and the demand for higher quality speakers.
I think this is where Clarion,Pioneer and Kenwood started making the high end stuff.
But I still dont know about those 4x10's.Why even bother.They could of just put 6x9's in those big bulky doors.
Andy, could you expand on that if you see this?ovals aren't inherently better or worse than round speakers and the ultimate performance does depend on the rest of the design.
However, the oval shape does "spread the chaos" of bending modes around, which often results in a diminishing of the peaks and dips caused by those modes. The different dispersion patters along long and short axes can also be helpful, but a 6x9 woofer (just like other speakers) ought to be low passed before the dispersion narrows if you're using it in a car.
He's talking about polar response. A 6x9 will beam like a 6" driver on the short axis and like a 9" driver on the long axis. Having read many post from Andy, he's a firm believer in LPing drivers before beaming in order to avoid having to angle the speaker.Andy, could you expand on that if you see this?
Yeah, I got that part. I wanted more on controlling dispersion in a car. Seems like he's not a big fan. There are two schools of thought on this.He's talking about polar response.

You bet... IIRC my parent's console stereo had 6X9's and they were in this strange styrofoam wrapped enclosure....Thats kinda what I was getting at.They need as much cone area as they could get to fit into the area they had available.Its like the speaker was just an after thought and shaped to fit.I think the 6x9 worked so well they just kept on using it.The 6x9 was a more efficient design than just a 4,5 or 6.
I have seen oval speakers in older home units also.Some were very large,15x10 inch's.
But I dont think they were as old as the automotive designs.But I could be wrong.
All of the oval speakers I've came across were IB except for the dedicated subs like the Boston SPG555-4.
