Welcome to Decware
For Live Listening Experiences without compromises.
Size: 60" high by 14" wide (excluding wings) by 28" deep. 150lbs ea.
Introduction
Commissioned by Lii Song for their flagship driver, this 29.5Hz Folded Horn was a no compromise design by Steve Deckert. The combination is so good we had no other choice but to name it 'The Headwrecker'.
The Horn Design
This design is licensed to Lii Song who will be manufacturing it for markets outside the USA. Decware is also building them (as shown in high performance black) for anyone who wants to pick them up from our facility in East Peoria Illinois, USA.
For those ambitious enough to DIY a pair of your own, we are providing the complete plans in both Imperial and Metric, 9 pages of each. This pair of horns uses exactly 4 sheets of 48 x 96" plywood. Cut sheets are included in the plans.
Available as D.I.Y. plans and fully built & tested

This horn design is made with a removable baffle making driver changes fairly easy. This is because the cabinet design will work with a wide range of drivers up to 10 inches in diameter. It is in fact a fun way to make inexpensive drivers sound like they cost a lot due to the bass response capabilities of the horn.
There is a design log in the Decware support forums for this horn. You can read about it here.
