1" small flat tweeters. Will fit in most pillar panels. Tweeters are threaded so u can tighten them with plastic "bolt" provided With speskers

Go to Polk audio .Com and look up this speaker. On the specs it will tell how big the hole needs to be.

The package is a pair of tweeters. There are also two styles of mounting brackets; a) trim rings for 'near' flush mount as the tweeters have a domed mesh metal covering, b) brackets for surface mounting which puts the tweeters about 1-1/4" above the surface. Each tweeter has attached leads with the 'bass blocking' crossover capacitor built in.

To avoid cutting the wire that connects the main speakers, to install this you'll probably need an adapter that converts the two speakers outputs in four - can get very cheap adapter on Amazon, specifying the make and model of your vehicle - or just cut the wire that connects to the main speakers. You just have to decide where you will place the tweeters.

The speakers are angled in their housing, so when installing them you would position the speaker to aim toward the listening area. Furthermore, the tweeters can be aimed seperately from the woofer in any direction. Hope this helps.

I do not see why not. Just depends on the level of modification you are up for. Crutchfield will tell you the size of the opening if you do not know. You should be able to build or buy a adapter plate if the hole is not perfectly round. Then you would cut a hole under the grill and mount your tweet or place it in the deck outside of the grill. As to the speakers themselves, I have personally never heard better. The Linkwitz-Riley 4th order crossovers are top notch and these ARE made by Harmon Kardon. Get them in and I bet you will be happy. :) Alternately, look into BSW. They make speaker specifically for your Beemer.

I did not take exact measurements of the existing opening since i was only using these speakers as replacements. I would say the existing diameter of the hole was 6". The speakers sound great and the blue LED lights are a nice touch.

These enclosures are for 6.5 inch circle speakers, not 6x9 (oval) or tweeters. The TW67 tweeters are 3", so no, they will not fit. It looks to me like those tweeters are a "special" size, so you may have to go custom, as in make your own. Also, I don't think that enclosures would improve the listening experience.

Speaker depth was an issue, these have a huge magnet... Also you may have to drill custom holes for the tweeters.

One does not need to use the tweeter housing.. The unit also comes with mounting cups for a flush mount. I used the cut tubes though since it worked for my application

My car had tweeters in the front doors already so it was easy to replace them with the new set as they were the same size. But I bought Two sets of these speakers one for the front and one set for the back doors the woofers fit both the front and the back. the back doors I chose to drill holes for mounting the tweeters which for my car was easy to do because the door skins are plastic and had a good flat area to mount them. They also come with hardware to surface mount them as well but you would have to figure out the best way to run the wire. The tweeter wires get connected to the larger speaker. By the way these speakers sound great. I replaced the stereo as well with a JVC unit.

Estimate: 2 1/2" diameter and if you use the pivoting mount estimated 2" depth. The tweeter itself is only about 1" deep.

No. They can be flush mounted in any of your door panels or where ever you can cut a one inch hole. They also have hardware for a direct mount where the whole tweeter sticks out like in picture. Honestly I blew mine and got a pair of Polk components. Stayed with the 6.5's but got the Mobil monitors or mm's . They ROCK!! they have a grill that comes with them that lets you mount the tweeter in it so it looks like a coaxial but they sound way better. You can move the tweeter to another location but you'll definitely want a hundred watts each to push em

You would have to drill holes in speaker. I would not do that. I made a larger wood plate that better fit my speakers. I attached that to the clamp plate and then put rubbeer/foam cushions at each corner to keep speaker from wobbling.

There are no holes so you can use whatever size in whatever spot the speaker needs. Will work with any 6.5" mid driver

The hole size can be measured but the way the speaker is made, there is a slight flange on the outside of the magnet at the bottom that is the maximum hole size. If it is exceeded too much by cutting, the speaker will not fit snug and the screw holes for mounting could easily be compromised so you have no place to screw the speaker in. These are heavy speakers so it is best to use all three holes. So trial and error is recommended.

not sure of hole size.....used speakers in 6x9 oval cut outs on Harley speaker lids...had to drill new screw holes because they didn't line up with 4 existing holes....they will not fit in a round hole...bass response is a little weak
