It was about 11:15am on Thursday 12th September when there was a knock at the door, I quickly opened the front door and there stood a delivery driver with a blank look on his face, I bet he was dreading this delivery all morning, what he had in his van was my brand spanking new Velodyne CHT15 sub weighing in at about 85lbs with the packaging, it was only the big red writing on the side saying Velodyne that I new it was the right item otherwise I would have said he was delivering a fridge, this thing was huge. Once in the front room I only had one problem, how to get the beast out, decided to slit the top of the box take the polystyrene off the top then turned the box on its end and just lifted the box off, turned the sub the right way up and there it stood in all its glory, as Uncle Eric calls it The Son of Godzilla On the back of the sub theres: Binding posts for input/output for left/right speaker level Line level input/outputs Three knobs, volume, crossover and phase High pass crossover 100Hz/80Hz Three chrome switches, auto on/off, video/audio and crossover in/out Power on/off Cooling fins for the 300watt amp Had run new cables prior to delivery so it was just a matter of sliding it into position and connecting it up and switching on the power, the green light came on straight away so with my SLM in hand started to set it up, simple, 5minutes and I was ready to see if what Jase and Uncle Eric had told me was true. First disc in was Pearl Harbour chapter 22, It was only 15/20 seconds in and the smile was already there, it wasnt the amount of bass that was present it was my whole speaker system sounded so different, have always had speakers set to small and bass sent to my sub (REL Q50), I always thought that I was relying on the amps crossover to redirect these frequencies of 80Hz and below, so how has this sub made so much difference? The soundtrack was so much cleaner more crisp, most noticeable was the dialogue, Im no good when things start to get technical so Uncle Eric, Jase anyone HELP. Anyway back to the planes and bombs, this beast had been woken up and was producing bass like I have never heard before, so controlled, tight and clean, what did stand out more was it does its job then shuts up, no harmonics (think thats what they call it) which I have noticed in the past can sometimes carry on over dialogue or run into another scene of the movie. Turned it up to 10 just for a few seconds the smile turned into to a big grin followed by Goosebumps. Ran a couple of other discs through, The Mummy and Behind Enemy Lines, truly amazing. Time for a bit of music, dont listen to a lot of music but have a feeling I will now, put Eric Claptons CD on, this must be the first time I have a heard a musical sub, again controlled, tight and clean, then gave it a CD of my sons to deal with, club music I think they call it, just ate it for breakfast, through all the demos and testing I didnt hear a hint of boom. Have always regarded my Rel as very good and to be honest have never wanted to upgrade, didnt think there was anything out there to beat it this side of £1000, that was until Jase recommended the Velodyne CHT15, so after a few words of assurance from U.Eric and Jase I went for it. Now I have one I can see what they were saying, This sub is a class act.
