2x Subwoofer amplifier for home

[Rupzzz94]

Hi all,

I am looking for a suitable amplifier to use with my subwoofers.

I have 2x 600w rms subwoofers with dual 4ohm voice coils (can be used in either 2ohm or 8ohm configuration, although if wired in series/parallel could potentially be used in 4ohm configuration).

I have looked at a couple of amps

Behringer NX1000D Review (Stereo Amplifier)

This is a review and detailed measurements of the Behringer NX1000D power amplifier with DSP. It is on kind loan from a member. Can't tell if it is discontinued or not but see it on sale at one place for $299. Retail cost is $549. I am a fan of orange displays and NX1000D delivers on that...

Behringer NX3000D Pro DSP Amplifier Review

This is a review and detailed measurements of the Behringer NX3000D Pro DSP power amplifier. It was kindly purchased new and drop shipped to me by a member. It costs US $399. As pro amplifiers go, the NX3000D is half attractive especially when on with its amber lights and LEDs: There are...

As they have dsp control which I also require so that I can setup a crossover etc.

What is putting me off is the asr reviews amir did on these amps, the power output rating advertised doesn't match the results of the testing.

I'm having trouble working out if one of these amps will be suit in one of the above configurations or not & if not, if there are any other amp suggestions anyone could give that will meet my needs?

Thanks.

You can ignore the manufacturer's claims and go by the test results. It's very common for manufacturers to fudge to some extent. There was a review of a Crown amplifier here and I was kind-of surprised that even they missed their spec (I don't remember by how much but I think it was "close").

You probably don't NEED 600W x 2, but that's up to you! If you have a sealed cabinet with the low-end boosted (more common with sealed cabinets) you MIGHT want the extra power.

I have been using PA amplifiers for my 8 ohm subs, with a separate standalone crossover (krk ergo). Current PA amp is the Img Stageline STA-2000d which has temperature controlled fans that never switch on at normal (80-90 dB) listening levels in my room. It is a bit more expensive than the Behringers, though.

I don't have experience with the Behringers but I used a similar PA amp of a different brand in the past (forgot the brand name unfortunately). I disconnected the fan and put it on its front with some feet underneath to get a natural air flow from front (at the bottom) to back (at the top) without fan noise. It never became very hot but did break down after about 5 years.

Although the specs in the brochures are bloated, PA amps will still give plenty of power. Drawback are the fans and you may hear some hiss coming from the speakers (which you won't hear anymore when listening at normal volume).

A more expensive alternative are the Hypex fusion amps: https://www.hypex.nl/products/amplifier-families/fusion-amplifier-family/
