NUFORCE AMPS FOR PASSIVE SUBWOOFERS

I've owned the Crown K1 and used it on my Apogee Studio Grand subs. Didn't like it. It had plenty of output, but no bass definition. I thought it would be the ultimate amp for my subs, but I was wrong. My Classe 201 amp smoked it but runs much hotter. I want a amp(s) that I can leave on 24hrs and not worry about heat/power consumption. Thanks for the Nuforce info Plato. Looks like 9se's are the ones to get! I just ordered a Velodyne SMS-1 so I need to find some power for my Kinergetic subs soon!

Give EarthQuake Sound in Hayward, California a call and see if they'll sell their plate amps separately. You'll have a high pass filter and gain control with low and high level inputs, little to no heat, and signal sensing auto on. Nice folks and great service too.

I agree with Ptheo regarding Crown's K series. I used one in my electric Bass rig, which includes a Bag End sub that needs 400 watts max, simply poor low level definition. For Pro amps check out Crest or QSC, I believe they're both making fan-less models.

Interesting on the K-series.

The two negatives are in contrast with what many others using them seem to be saying and in contrast with my own experience.

Whoaru99; In an effort to qualify my comment I can only offer simple comparisons. I'm currently using a Velodyne DD 18 in my two channel system, an EarthQuake Super Nova 15 ( dialed in using the Velodyne program) in the HT setup, QSC PLX 2402 driving a Bag End ELF-M / S18 E subwoofer and a D10 BX for stage Bass amplification.

Before purchasing subs for the audio systems I would frequently use the Bag End system at home. During that time I had the opportunity to use amplifiers from Crown ( K and Macro series ), Crest, Yamaha, Eden, Carvin, and QSC, in both stage and audio applications. While all the amplifiers drove the sub only the Macro, Crest, and QSC could reproduce accurate tone and fundamental from the B string of my Lakland 5-94. The K would shut down often during a live performance and had a noticeably thin sound both on stage and at home. On the other hand the Macro preformed well but it's size, weight, and the poor service Crown offered with regards to the K kept it out of my rack. While low bass is not as abundant in an audio application as it is when playing a five string bass, the definition is still obvious.

A driver/cabinet unable to resolve a flat signal into the low twenty's as well as a room too small to handle the wavelength produced by such a cabinet can easily mask an amplifiers ability at this low level.

I am in no way questioning your experience with this product. If Crown's K series amp is working for you that's great, they're economical and abundant.

I have SW800's and drive them using a Kinergetics KBA75 (100w Class A). If you want something small to hide behind the subs, look at the Meitner MTR101 mono blocks. BTW, how did you decide you needed at least 300 watts?
