Project Category:
Freestyle Speakers

Project Level:

Project Time:
8-20 Hours

Project Cost:
$100 – $500

Project Description:
Our Jazzspeaker V2 has 2 Drivers and 2 Tweeters, it is designed to sound great, and look great!
With a baffle made out of solid Padauk it is a one of a kind bluetooth speaker!

Design Goals:
– Make a Bluetooth speaker that looks amazing
– It should have plenty of low end (without a sub)
– It should be able to fill a medium sized room with sound

Crossover Design:
It’s a simple Butterworth crossover

With all boxes checked, I’m really happy with how it turned out!
I’m hoping to build variations of this speaker in different woods!

About the Designer:
Since I’ve build my first speaker about a year ago I’m hooked!
I found my passion and I continue to build more speakers to improve and learn as much as possible!
I’m working hard because I love it, I’m hoping to build speakers for customers in the future and start my own little business!

    This thing looks great and i really like your choice in speakers, I have been thinking of building something in that size.
    Again i really like your choice in speakers, would you mind sharing your crossover design with us?

      Hey Jake, Thanks for the kind words!
      I’m pretty new to crossovers, so I made a really simple crossover using an inductor on the woofers an a resistor and capacitor on the tweeter.

    Nice work Bud! However if you would like to take this to another level and build up your business you are going to have to think outside of the box. Literally!!! Cause every schmuck is making a similar box now… Good luck and Cheers!

    very well done, I would like to build similar for my personal use
    how did you achieve the low end? is the box ported or is each woofer/tweeter section sealed and portioned off inside

    thank you

    I am a fan of the “ND” drivers. They are high quality drivers at a great price, and do perform quite nicely in the lower end of the frequency spectrum. On your next build you might want to take a look at the ND91 version for the woofer. The physical size is the same as the ND90 but the performance is a better. The modest upgrade in the driver will provide 50% more power handling capability (30 watts vs. 20 watts) with 10 Hz added to the low end and increased 2 KHz on the high end (70 to 17,000 Hz for the ND91 vs. 80 to 15,000 Hz for the ND90).

    I am designing a line-array using the ND91, like you, for the specific purpose of eliminating the need of a separate subwoofer. Additionally, I like clean look of the simple black anodized aluminum alloy cone. When wired in a series-parallel configuration and mounted in a tuned box you will get the low end you are looking for. You will be surprised (and delighted).

    Contrary to a comment on the front baffle mounting, I like the simple clean lines of your speaker, and don’t know of a better way to mount the drivers such that the mounting flange doesn’t show. If you know of an alternative way that would look as good I would like to know what it is. Keep up the good work.
