Hard to agree with it because it could be true about 10 years ago or more but nowadays manufacture learned how to create larger speakers to maximize cone size in an available space, since larger cone area moves more air they produce clearer voice. So it all depends on your requirements. Round speaker wins over oval only if you want more bass but if you want clear sound for the voice then keep the original oval. Trust me...it is there for a reason and if you want more bass then you always can add a subwoofer (that's what I did actually) but if you upgrade the speakers make sure to get a good trusted brand.axel10 wrote:An oval speaker is inherently less powerful that a round one, so I decided to stay away from duplicating the mistake Nissan made by using a 6x9 in the front doors. Instead I used a 6x9 adapter to install 6 3/4 speakers in the front doors (can also use 6 1/2 speakers) - which give you many more options in quality and sound.
I am no audio expert, but basic physics tells me that the exact opposite is true. A larger speaker will displace more air and thus create more bass. A 6x9, or an oval speaker, has more area compared to a round speaker of similar size, which means it will produce more bass. However, a round speaker is inherently more rigid compared to an oval, and as a result less likely to distort (=superior sound), which is why I prefer a round speaker.Leo2005 wrote: Round speaker wins over oval only if you want more bass but if you want clear sound for the voice then keep the original oval.
