Foam, cloth and rubber are the most common. "Audiophile" speakers will usually have a well-attached rubber surround. For those applications, I think the emphasis is on material properties like mechanical compliance, which is presumably better sonically. In a car door, rubber will probably last a bit longer and take more abuse.<font face="Verdana, Arial" size="2">Originally posted by sthack:

Chuck!, I recognized your user name from the Yahoo Ody Club. By the way, nice pics of your ody!
I went to Circuit City and the sales person wanted to sale me a pair of Polks 5 1/2 at $90 pair installed. I'm not familar with what are good speakers so I'm doing my research. So far, most people are recommending the Sony X-plod or Infinity.

Note that for woofers, the rated sensitivity spec is pretty worthless to judge the amount of bass you'd get below 150 Hz or so. To get the true efficiency and sound pressure level limits, you need to know the box size and parameters. Some rated with high sensitivity will have poor efficiency in an enclosure size/type they weren't optimized for. Really requires software, and I think partexpress has a free program for it, too.<font face="Verdana, Arial" size="2">Originally posted by Rook:
Sthack,
Sensitive speakers can have more efficient output with less power supplied to them. 90db to 93db is common, the higher the number, the more sensitive they are.

I just picked up a couple of pairs of these component Blaupunkts.bobf58 said:When I upgraded the speakers over a year ago, the Crutchfield salesman recommended and sold me the Polk 5-1/4's for the front, and Blaupunkt 4's for the rear. The Polk's sound pretty good, but since I haven't heard the Sonys or Infinitys I don't know how they compare. The Blaupunkts don't sound so great, the volome is much lower in the rear, but I doubt any 4" speaker will sound very good in that location without doung some kind of enclosure modification.
I just installed these in the wifes 02 Ody. I was able to mount the tweeters onto the grilles front and back so they are flush mounted. I would have rather installed a 6 1/2" speaker but Crutchfield has the 02 as a 1999 in their db and dont show the 6 1/2. I went ahead and mounted these anyways and they do need a sub (we have the kelton under the driver seat) and I am very pleased with the clarity it has added. I disconnected the dash-stock tweeters. I got them for 49.95 a pair and would recommend them if you want to mount seperates in an older Ody.CMasten said:I just picked up a couple of pairs of these component Blaupunkts.

Has anyone ever tried them? Crutchfield has them for 59/pair and throw in the adapter ring for the front and the interface cables. I have not seen any reviews on these and was curious how they sound in an Ody.
