Infinity Primus PR693C (INFSPKPR693C)

Not Really Factory Head Unit Compatible?

I purchased these to replace factory speakers in my Nissan Xterra. I am powering these with the factory head unit which may be a contributing factor to my experience. I primarily chose these due to their 3-ohm impedance to pull more power from my factory head unit since I do not want to get into a full system overhaul. The frequency response numbers looked decent, but after hearing them I want to see a chart.

The grittiness of low-fidelity streaming was exposed by the clarity of the tweeters, CDs and lossless streaming were MUCH better. The tweeters are a little on the harsh side overall so I leave the treble rolled back a bit.

The woofers have a really punchy mid-bass (which I like) but the low end really falls off fast below about 80/90Hz (which I don’t like). These do not make the cut as full range stand alone speakers for my application. The factory speakers out-perform the Infinity speakers when paired with the factory head. The rear factory door speakers now sound like subwoofers and carry all my low end.

I bet these would sound awesome paired with a modest subwoofer to round out the low end but I do not want to get into buying and installing a new head, amps or subs to attempt to improve their performance in my particular vehicle application.

Really nice clean speakers would recommend for any build sound quality is great and works well with an amplifier powering them
