About Seas Thor Speaker
Premium MTM design using Seas Excel drivers in a transmission line cabinet. Transmission-line (TL) loudspeakers have long enjoyed a small but dedicated following, especially in the DIY community. The advantages of TLs are well known. They are essentially non-resonant enclosures, producing a deep, well-controlled bass response. For a given driver, bass response can often extend well below that produced with either a vented or sealed enclosure using the same driver. Above a few hundred Hz, the line-filling material completely absorbs the driver back wave, giving the TL an open, non-boxy sound.
The Seas Thor kit is design around 4x Seas W18E-001 7" woofers, 2x Seas T25CF-002 in MTM arrangement. The two W18 Excel magnesium cone woofers and the T25 Millennium fabric dome tweeter are mounted in a D'Appolito configuration. The D'Appolito configuration offers a number of advantages over standard single-woofer designs:
- Controlled vertical directivity in the midrange which reduces the effect of floor and ceiling reflections.
- Excellent imaging and spatial characteristics.
- Higher system sensitivity.
- Lower distortion.
- Increased bass output.
For more in-depth information about the design, please see the article by Dr. Joseph D'Appolito and Dennis Colin in AudioXpress.
This e-bay listing does not content any parts or materials – only drawings for a suggested raw layout. You are free to make your own design such as veneering or paint etc.
