Do you own an ESS AMT1A, B, C, D or LTD? Do you love the bass and highs, but realize there is detail missing from the mid-range. The speed of the 12" cone woofer, as good as it is, has a difficult time mating well with the Heil AMT Tweeter. Our N69R is the ultimate bridge; it allows the 12" to operate in its comfortable range, places a extremely fast 6 X 9 driver at its optimum range of 250Hz to 2000Hz, which allows the AMT to operate with a 6dB per octave slope. The other great feature of the 6 X 9 is the polar pattern mates with the Heil tweeter beautifully. All of the drivers cover the range they are best suited to cover while maintaining the awesome bass and highs of the original system. Comparatively small footprint, sleek, modern looks and only a modest investment; you can transform your current speaker into a giant killer!

Crossovers, tweeters and other parts that are needed by most are just more things to breakdown and degrade the sounds quality.
