Hertz UNO Series K-165 6.5" Two-Way Component Speaker System (Pair)

Excellent speakers. I came across these on a Youtube video by a Mercedes R129 SL owner. I only used the 6.5 in. woofers in the doors of my 1996 Mercedes SL320 with the factory Bose sound system. The original tweeters still worked fine. Perfect fit. The original screw holes lined up fine. I just added some 1/8 in. thick adhesive neoprene rubber to the back of the rim of the speakers to insulate the mounting. I had previously purchased the neoprene rubber sheet on Amazon.

I have replaced both of my Alpine and Kenwood sets with these speakers. They are so clear and crisp running off of an amp or factory stereo. The highs are super crisp but not shrill or fatiguing, the mids are clean and punchy. I paired them with Hertz DCX 165.3 in the rear and a single CT Sounds 8” Tropo and everyone thinks I have thousands in my setup. I can’t recommend enough.

I was looking to upgrade my factory speakers that are already old and sound like a box of candy so a friend recommended these and they are good

While they are a breeze to install. The tweeters are a bit shrill and the midbass leaves a bit to be desired. A deffinite upgrade over stock but next time in going with either a tried and true line of hertz or morrell maximos because I know I wnjoy and trust their sound and quality. If space is a concern these are excellent

Outstanding sound quality. Also these have high sensitivity which means they play louder at any given wattage. If you're only powering these with a head unit (less than 20 watts rms) and not an external amp, then you especially should consider these speakers. That said, they are also outstanding at higher wattage.

Good

I'm currently running Uno series components up front and Uno series coaxials in the rear. All being pushed by a Recoil Di550 4 ch amp. Once gain settings and frequencies are dialed in, it's a natural mini concert. They sound so clean and articulate. Snares, hi-hats, vocals and chimes come through beautifully with this setup. I previously had JBLs all around and these Hertz Unos sound way cleaner and detailed. They handle all genres with ease, detail and clarity. And to think this is Hertz's "entry level" component speaker line, I can only imagine what their top tier has to offer.🎼🏆

Mi humilde opinión...para ser un midbass no entrega mucho bajo es más media vos por las voces no lo voy a negar se escuchan más fuertes y claros por qué tienen muy buena sensibilidad y los tengo directo a mi radio pioneer single din. Talvez amplificadas se escuchen mejor. Los tweeters si son muy chicholles aún que tienen filtro pero si son muy agudos como los típicos tweeters de pastillas. Y eso que tengo en plano la ecualización de la radio. Pero si tú traes un subwoofer todo combinado se va a escuchar muy bien.
