Because of this, the subwoofer is not receiving the 3-6dB boost from the boundary effect from the floor. The subwoofer and desktop monitor were placed on a tall stand to simulate anechoic conditions. Subwoofer 15”H x 15”D x 20”W with integrated legs.6″ SB Acoustics SB17CAC35-8 ceramic woofer.Sealed enclosures for increased transient response.Beautiful wood grain with hand-rubbed oil finish.With its 10″ subwoofer and sealed cabinet design, it can get as low as 28Hz. The final design follows closely the form-factor of the footrest that is beneath my desk and is painted black. The subwoofer had to go as low as possible while still being inconspicuous and out of the way. The combination of those two provided the widest possible range (55Hz-22kHz) while having the flattest response. That is why I bought ribbon tweeters and ceramic woofers for the desktop monitors. Since I invested so much time into the outward appearance, sound quality would have to be top notch. Finished by filling with blue glow-in-the-dark resin, I think I fulfilled my goal.

Drill bits, straight router bits (1/4 in., 1/2 in.), flush router bit 1/2 in.It is Low cost, sturdy, easy to work with, and neutral in terms of frequency response. Up to a 10% of error in size would not affect the box freq response as bad as in a ported cabinet would. Small enough that makes sense for my application, while keeping an acceptable low freq response. 55 ft3, based on the recommendations of one reviewer of the speakers. They match up well, having to decrease the response of the tweeter by 3db for a flatter frequency response of the speaker as a whole. The tweeters specs: Operating Bandwidth: 3.5kHz ~ 30kHz, Power Handling Capacity of 200W and RMSSensitivity: 92dB (1W/M). The woofer specifications are: Operating Bandwidth: 50Hz ~ 6KHz, Power Handling Capacity of 70W, and RMSSensitivity (1W/M): 89 dB. I chose a pair of MCM Electronics part number 55-2971 (8" Woofer) for $27.77 including shipping, and a pair of Pyramid Tweeters (TW-12) that I bought in ebay for $6.99 shipping included. It started with the selection of low cost and relatively good performing woofers and tweeters.
