I have been using a ADS Sub 10 in my main audio system for the past more than 15 years and it has continually performed very well - augmenting my system with deep clean base.
Wile other speakers come and go my ADS sub will stay till it dies......Jim
Who uses ADS Speakers
I worked at ADS in The late 70s and Find they are one of the best home speakers ever.
I always loved their accuracy.
