Beats My Factory Speakers by Far - Lack Som Bass

These speakers are great and beat out the factory speakers that came with my car. Instantly I could hear a difference and so could my fiance who had no idea I switched out the speakers.

I replaced my mid speakers with the Polk Audio DB 652's and I could play my system at full volume and they did not become distorted or sound rattled. I noticed that compared to the stock speakers that they did not lose anything when turned up. I actually feel they performed better loud.

One thing I did find is that they lack a little bit of base. They are great with the highs but I need to balance out my system with a few other speakers that have some good mids.

I would recommend these speakers to anyone who are looking to replace their factory speakers or get something great to enhance what they are listening too.

Better than I expected

I've had these installed in the doors of my Scion FR-S for about 4 months now and they sound great. My doors are lined with Kilmat (Dynamat alternative) and it probably helps a lot with sound reproduction cause these things can definitely put out some bass for their size. These won't replace a sub or anything but they sure beat the factory speakers.

These are very bright sounding speakers out of the box. Good thing my head unit has an auto equalizing feature that uses a microphone to do time alignment and equalizing automatically. Now they sound great and aren't as bright as before. They're seeing about 100w rms to each speaker so a total of 200w rms and they are plenty loud.

All in all, they're great for the price and I'd definitely recommend these and buy them again for my other vehicles.

Polk Audio DB652 DB+ 6.5-inch (DB 652)

A substantial upgrade to the sound quality in our RV compared to factory installed speakers. Easy to install with all parts included for installation.

Only Con is that the Polk speakers made deficiencies in the factory installed AV unit more obvious. I will be looking for a higher quality AV receiver with more power and additional capability.

Excellent speakers

My dad loves these. They produce a clear sound and can get quite loud. Great bass too.

Fits In front and rear doors of 2004 Volvo v70.

Wonderful sound

I just installed the speaker over the weekend, it is not a fair comparison of sound quality over the factory speaker. These speaker kick a**.
I can not wait for the weather to get better so I can drive my 350z with the new sound system cranked.
