The Sampan DTL

Role Audio Sampan DTL
Dual transmission lines for double the power of the Sampan

Shown: satin black
Dimensions: 4 X 6.25 X 41 inches, (W X D X H),10 X 16 X 104 cm
Frequency Response: 35Hz - 20kHz (+/- 3.5 dB)



In his review of the Sampan, Dr. Jeff Rabin noted that, "Even a respected Lowther cabinet builder ... said he could not believe the quantity and quality of bass that was being reproduced from such a slim little cabinet." And that, he heard ".. imaging to die for, and a speaker disappearing act that [he] wouldn't have believed possible."

Imagine, the dual transmission line Sampan DTL has twice the bass output of the Sampan, and the same incredible imaging, in a cabinet that is the same four inches wide, and only four inches taller and 2.5 inches deeper than the Sampan.

The Design of the Sampan DTL is informed by the design of the Enterprise and the Sampan loudspeakers. The Sampan DTL uses two 3.5 inch drivers and dual transmission lines (like the Enterprise) in a cabinet that is only 2.5 inches deeper than the Sampan to deliver riveting dynamic performance with an unbelievable quantity of superb deep bass. Think of it as producing double the output of the amazing Sampan micro tower.

Instead of using crossovers that can sap up current and lead to sonic anomalies to integrate and flatten the response of the drivers, we take the very novel approach of using two different full range drivers with frequency response curves that complement each other and transmission line bass loading to provide extremely linear full range response from 35 Hz to 20 kHz +/- 3.5 dBs and a sensitivity of 92 dB. 

The Sampan DTL is a time coherent, minimum phase, point source design. It frequency response covers the audible sound spectrum. Because of the Sampan DTL's full-range, dual transmission line design, in most cases a subwoofer will not be needed, especially when the Sampan DTL is used in stereo systems in medium and smaller rooms.

The svelte design and incredible dynamic performance of the Sampan DTL also make it well suited for use with today's flat screen TVs in home theater systems. Its dimensions are an amazing 4 inches wide by 6.25 inches deep by 41 inches high. Used solo or combined with a small subwoofer, such as the NSMT Model EXP, the Sampan DTL makes a compelling home theater audio system visually and sonically in either a 2, 2.1 or 5.1 system.

How can the Sampan DTL image as well as it does and at the same time deliver incredibly extended bass?
