All of them sound pretty darn good, so I wouldn't get hung up on which one he has. But my memory is that they are identified on a little plate on the lower back.
Sigh...The original Time Bass, as the Time Window subs were called, were Reuleaux triangle-shaped on top and had the same grille cloth (the foam filter type material) that was on the TW. I don't recall exactly how it worked (powered or not). It made a very big difference in the sound of the mid-bass of the TW as it took the deep bass out of the TW allowing them to do the upper frequencies better.
No, the Time Bass were originally, specifically designed to operate with the Windows.. I know..I sold them!!!! If memory serves me they were actually spelled "Time Base".
No, the Time Bass were originally, specifically designed to operate with the Windows.. I know..I sold them!!!! But we only had 2 pair per store..I remember selling at least one pair. They had passive crossovers. If memory serves me they were actually spelled "Time Base". The TW's were $660 pr and we sold them like hot cakes after the 1980 Audio Critic and Sun Times reviews. The Time Base was about the same price. They looked like short, fat Time Windows. The designer and owner of the company Bob something used to come down to Oak Lawn from Grand Rapids and we used to talk all night............
Jack, Skip, Terry and Rob.....and you are?Yes.. The original Time Windows didn't say 1 but they were the first ones. I worked for Sights and Sounds, Oak Lawn and Chicago Heights, IL..We sold more than ANY other dealer according to DCM in 1980..There was/is a subwoofer that they made also for the Windows.. Very rare.. Sounded awesome in the store with Yamaha C2a, M2, T2, PX2. Good Times!
