Polk Legend L100 Premium Bookshelf Speaker Brown

New Pinnacle Tweeter: the new ring radiator tweeter design dramatically improves dispersion while delivering clear, crisp natural highs good.
New Turbine Cone: delivers smooth and incredibly detailed mid-range imaging.
Enhanced Polk Power Port Technology: produces less port noise and more powerful cleaner bass than traditionally ported loudspeakers.
Anti-diffraction Magnetic Grilles: Acoustically inert grilles offer a clean aesthetic without sacrificing sound.
Power Recommendation: 70W or more per channel power amplification is recommended to experience the best quality and performance from these speakers.

Enjoy better views through your telescope with this premium diagonal featuring diffraction-limited optics and dielectric coatings.
Provides a 90° viewing angle, perfect for more comfortable viewing through refractor and cassegrain-type telescopes.
58 layers of dielectric coatings provide an over 99% reflective surface, ensuring the maximum amount of light collected by the telescope reaches the....
Twist-lock keeps the eyepiece centered in the diagonal to provide better optical alignment.
Accepts standard eyepieces, Barlow lenses, threaded filters, and other accessories with a 1. 25” Barrel.

Basic spectroscopes able to view variable light spectra.
Hold it up to different lights to observe which wavelengths are present.
Light enters through the slit and is split by the diffraction grating at the other end.
Perfect activity for students at school or kids at home.
Each spectroscope measures 10.25" long. Body has a diameter of 1.
