Peter Tribeman from Atlantic gave me a call in late spring raving about this new technology. I met Peter when he was looking for beta testers for the 970 processors at the Outlaw site and was chosen to be one of the beta testers.
He invited me over to the Atlantic offices in Norwood to give them a listen. He started out playing the big Atlantic subwoofers to get a feel for good bass (and it was tremendous) and then was going to switch to the H-Pas system. The program material was standard CDs with some very deep bass lines: percussion, and some other stuff I don't remember.
After listening for a while, I asked that he switch to the H-Pas at which point he revealed that he had played an old trick on me: I had been listening to the H-Pas all along. The original system I heard had two 4.5" woofers from one of the Atlantic speakers installed in a rather slender tower. I must say I was stunned at the depth, power and cleanliness of the bass.
The system I heard needed some work on the top end as it was rather harsh and forward. Peter said that the designer was aiming at perfecting the bass for the prototype and that the finished product would have a more sophisticated crossover.
I asked that he play some deep bass, and I ran over to the speaker to see if the cones were jumping out of their spiders (I think that's the term) during the lowest notes. Amazingly, they were not. The amount of cone movement did not justify the depth and quality of the bass that was playing.
Thinking that Peter was playing a trick on me, I walked around the room looking for a hidden subwoofer that was making the deep sounds. There was none. From this brief encounter with H-Pas it seemed that for once I really heard a "breakthrough". It will be interesting to hear production speakers that incorporate this new technology.
In search of the Holy Grail.
