Sierra-1's with Rythmik 12" servo sub
Just sharing an experience with the forum.
I have been enjoying my Sierras since Ascend began selling them back in May(or was it April?). Anyhow, I initially ran them full range before hooking up a Onix Rocket UFW-10 sub with them. For movies it was a very good combo, though not quite as deep as I would have liked. For music, I prefered the Sierras full range w/out sub. It just seemed to get a bit muddied at times, especially compared to the incredible detail of the Sierras.
I decided to sell the UFW-10 and put together a 12" direct-servo sealed sub from Rythmik Audio. I had a 2cu.ft. sealed enclosure built by RAW Acoustics since I don't have access to the equipment to do it myself. I had the Rythmik kit sitting in the boxes and was just staring at them, so I needed to do something.
From the first time I turned it on I could tell right away a big difference. Smooth and deeeeeeeep. It may lack some upper bass slam of the UFW-10, but it goes very deep and stays composed. It compliments the Sierras almost perfectly. I say almost because I think there will always be an advantage to running the Sierras full range w/out a sub. It will simply sound more cohesive. I'm not saying the sub does anything wrong, just my opinion.
Now for something that caught me off-guard. Last night I had put in the Tokyo Drift DVD. There was the scene of the parking garage drift race. I had to use the bathroom and let it play. As I was looking in the mirror, it was shaking violently. I thought at first I had bumped the counter top and made it shake. I realized it was shaking from the sound pressure produced by the sub in the livingroom, down the hall. It was almost like there was an earthquake. The sound did not bother my ears, but was like a natural low frequency sound from, say, lightning. I was impressed.
Anyhow, that's it. Anyone looking for a very good sub to pair with their Ascends should definitely give Rythmik a look. Brian is a pleasure to deal with like Dave F. here.
