Priced per pair

Bought these to replace my son's factory tweeters on his Xterra. They are way better than i thought they would be. Super clear and loud. Pair very well with his Kenwood head unit. For the price don't think you can find better.

The Honda Accord Coupe 2009 (7 speaker install) has awful front door tweeters. Even when I am listening to books or podcasts the treble quality often has a raspy or overly sharp, pain inducing quality, especially with the "S" sound in music or narration. I am hoping these help.

Good price point for a very well known brand in the sound world. [ Nathan  Mar 06, 2016 ]

I recommend a crossover. [ Tina  Sep 19, 2015 ]
No you don't need to install a crossover. You can wire directly to the door speakers. [ JEFFREY  Feb 09, 2015 ]
yes you`dd want high pass filter to use 120HZ and up. check parts express. [ Denver IT  Feb 08, 2015 ]
You can wire them direct! [ JONAS  Feb 06, 2015 ]
I would recommend using a crossover, Simply because they direct the proper Frequency to the tweeter usually 2000Hz/20,000Hz and woofer also known as Midrange typically 300Hz/5000Hz.In line between Head unit/source and speakers. Front or Rear channel. Your ears and friends will like what they hear With a crossover Installed. Michael [ Michael  Feb 06, 2015 ]
You can wire them directly to the factory wiring. No crossover is needed. [ MATTHEW A  Feb 06, 2015 ]
