full mids and highs

These three ways are solid, especially for the price. Mids and highs are perfect, not too pingy like mbquarts, but still full. I have yet to get distortion at high volumes so I feel they would do well in a component/amped set up. Cant comment on there low end response but specs say they can go pretty low. Packaging was protective and they came with plenty of speaker wire and mounting brackets. Overall awesome for any set up. I would recommend to anyone looking for full range door speakers.

Great Value

These were replacement speakers for a 1997 Chrysler Sebring LXi. Great speakers for a Great price. One would be a fool to not, at least, give these people (Sonic Electronix) a look.

Great product, awesome sound for the price!

I was looking for replacement front speakers for my car and got these because of the price. Had them installed and they exceeded my expectations. I would definitely recommend Rockford if you're on a budget and want a good quality speaker.

Can't go wrong for the price

Fit perfectly in the stock location and came with everything I needed to install.

The brand name for the price sold it for me!

I have worked with Rockford Fosgate equipment before. It is really top notch stuff. When I saw that these speakers were listed for the price, I couldn't stop myself from buying them. The Rockford equipment I've worked with before has amazing sound, great quality, very durable, and has great range. These speakers are no different. They have a range that's a bit on the high side compared to my stock speakers. This actually worked out for me because my stock speakers had a lower range which made the bass a bit overzealous. Couldn't have bought a better set of speakers.

Clear mids and highs

after a couple of months waiting to get a new set of speakers to go in the rear doors of my truck these Rockford fosgate R1s match the set up front and fill the cab with rich clear highs and mids but not the low end part but that's what subwoofers are for
