Speaker Sizes and Adapters

[DOZIER]

As all of you know, there are many questions on speaker sizes and round versus oval. Hoping to clear a few things up, I am posting this small thread on some pros and cons for the different speakers.

Many vehicles come factory with oval speakers which in turn tend to sound like crap to some degree. They might be acceptable to the normal person, but to the majority they tend to not do the trick and need to be the first modification to the vehicle. Replacement that is.

The round speaker has a smaller surface area than the oval speaker when you are replacing in the stock speaker mounting location. The round speaker to fit in the stock oval location requires an adapter plate or speaker adapter, however you prefer to say it. The round speaker is more rigid than the typical oval speaker due to it being symmetrical. In higher volume the round speaker maintains a better response and sound than the oval speaker which tends to distort in higher volumes. The oval speaker does produce more bass however in lower volume due to the fact that it does have more area, thus pushing more air resulting in higher bass output. So when changing from the factory sized oval to a smaller round speaker, you WILL lose bass. However the sound quality is much better with the round speaker.

If you can manage to customize the stock speaker location and install a larger round speaker than the factory oval-sized speaker, you are in a win-win situation, resulting in a better sound due to the rigidity of the round speaker and matching the surface area of the oval speaker, meaning same bass output, and higher volume without the distortion of the oval speaker.

All this information was obtained from Polk Audio, and Crutchfield
Advisor. Other information was also found using Google. Below is a link to an affordable site to purchase speaker adapters or speaker plates. I highly reccomend checking it out. Great site. Easy to follow.

1 little tidbit more, building your own adaptors aren't that hard either, and can be quite a cost effetive alternative to buying adaptors, then possibly waiting for them to come. (Often times they are flimsy plastic.)

masonite and a scrolling saw has always made my adapters.

I figured for the price of 5-7 dollars, you could not go wrong with the site listed above. Thanks for the added input.

CPL DOZIER,

I, too, have used Mike's Speaker Adapters on many vehicles. I first tried some a few years ago when he posted about them a few times in the audio section of this site and have used them ever since. He was the only place who could deliver on some of those weird adapters for some Chryslers and Corvettes, too.

His adapters and his spacers are five times the quality of Metra and Scosche adapters at half (or less) the price. They are cheap in price only - not in quality. His price for shipping is realistic and the items arrive quickly. If you don't have the time or talent for making them yourself, his are a high-quality alternative.

Just vouching for the quality and dependability of mjm. I have no ties to the company other than being a satisfied customer. I am not a member of his referral program. If you don't have the time or talent for making them yourself, his are a high-quality, low-priced alternative.
