higher gain than the Red Dragon S-500
Why???? This is a typical problem for any active crossover and we solve this with attenuation of the gain. QED.
Need recommendations for high gain/small footprint class d amplifier
I'm looking for a smaller sized class d amplifier to biamp the bass drivers in my custom speakers, which I was told should be about a 3 ohm load. I'd say something with at least a nominal voltage gain over 30 dB should do. My stereo rack was built for smaller components, mainly using Bel Canto and Red Dragon currently. I can squeeze something up to 13.75 inches into the rack but a bit narrower would be easier to work with. I've been considering the Channel Islands D-500 but would like to keep it under a $1000 used if possible. Your recommendations are appreciated.

@icherepkai you certainly could use them just for low end but they are designed for and most capable full range. I like the casing designed for ventilation and the somewhat industrial look actually. Very unique. Also when you turn it on you get some cool flashing led effects from within as it powers up. The dimly lit power button is a nice touch. It’s about half the size or less of the Schitt Freya pre-amp I use it with. |
If you decide to go with Hypex NCORE like Buckeye, spend a little ($300) more to get NCOREx line such as NCx500 instead of NC502MP. The amplification efficiency (A.E.) is better for handling lower impedance loads https://www.buckeyeamp.com/shop/amplifiers/hypex/ncx500/2_channel Speaker Imp. NC502MP A.E. NCx500 A.E. 2 ohm 450 watts 32% 700 watts 46% 4 ohm 500 watts 71% 700 watts 92% 8 ohm 350 watts - 380 watts - Price $695 $995 As shown, NCx500 will handle 4 ohm load speaker much better. The amp efficiency from both models for 2 ohm load are still not great but not bad for handling not so demanding low imp. speakers for the price. |
