Friday is the night. You don't have plans any more, because what you should really be doing is heading up Canyon Boulevard around 8 p.m. to go watch some of the region's best music played over the region's best live sound system and cast in the best light that money can buy.
I'm talking, of course, about the amazing new-ish large music venue in Nederland, The Caribou Room. And the show du jour is one of my favorites, Boulder's own Intuit Band, whose 2017 release "Canyon Roots" topped my list of best local albums of the year.
Boulder/Lyons music staple Bonnie & The Clydes will open the show with their energetic, self-branded "Rocky Mountain Country Soul." Lead singer Bonnie Sims and her husband and Telecaster master Taylor front the band and will provide a wonderful counterpoint to Intuit's reggae and world-music-infused sound.
The show is perfect right there, so as pure gravy for those of us making the trip up the canyon, local crooner Halden Wofford and his band The Hi-Beams will set the tone of the night as the show opener.
Consider this lineup to be three headliners, really. And let me be clear. When I saw Intuit at the Caribou Room last spring, it set a new standard in my mind for absolute quality of experience from beginning to end. Every detail was tuned to create a memorable night for both band and listener alike.
The folks at The Caribou Room are adept at giving both the artist and the viewer everything they and we need. Artists hear themselves well onstage and thus enjoy the experience to the point of inspiring extra creativity and musical awesomeness.
Do it! Intuit! This show is going to be absolute fire. Apologies for those who read this column on Saturday or Sunday — you'll have to catch the next one.
The Helmholtz approach
I've been writing a little bit over the last few weeks about different styles of speaker design. Mainly, I'm trying to find examples of the operating principles of these designs existing in modern life.
Maybe not so modern, but blowing across the top of a jug or bottle to create a tone is something we're all familiar with. This is what's known as the Helmholtz Resonance, discovered and documented first in the 1850s by Hermann Helmholtz.
Chances are, you have a Helmholtz resonator in your house right now. If you check out the back or front of your speakers, you'll probably see a hole opening with a tube going into the box behind it.
Speakers create waves behind the drivers too, so the box sees pressure changes inside, which act like your breath going across a bottle. At the right spot, where the tube is tuned, sound waves forcibly exit the box through the tube.
Speaker designers decide to place this extra "oomph" at a spot where it's difficult for the speaker to make sound, thereby supporting what you hear. This most commonly appears in the bass range.
That's why the speaker design is called a "bass reflex," and it is the most popular type of speaker in the world.
