Best Bass Amp!


I’m in the process of rebuilding my pair of Kinergetics SW-900 linesource subwoofers that have six 10” drivers per side. I need input on choosing the best sounding(5hz-80hz), most powerful, hardest hitting & most important cool running(most likely Class-D)monoblock bass amplifiers. I prefer ‘always on’ or ‘auto turn on’ if possible. No built-in crossover needed since I’ll be using my Pre/Pro for that. They will be used for music(40%) & home theater(60%) to mate up to my Apogee Studio Grand & Dali Megaline speakers.

I want to stay under $2500 price new/used for the pair if possible.

My choices so far are:

Bel Canto Ref-1000

Wyred 4 Sound SX-1000

PS Audio M-700

Emerald Physics 200.2SE(in mono)

I have a Coda Continuum No. 8 Stereo Class-A amplifier I will be comparing to hear the difference with the digital amps listed above.

FYI- I’ll be replacing the stock Vifa woofers in the SW-900 with Dayton Audio Reference 10” woofers(model #RSS265HF-8).

Please help me select the best from the list above or add any other amps you can think of that would be better.

Thank you!

Here is a better example of rudeness on Audiogon. Peter S. purchased a pair of speakers from me on here that were rated a 6 due to some face checking and a good sized nick on one of the cabinets. In my ad I stated I was rating them 6/10 for cosmetic issue and heavily discounted the price accordingly.

When he recieved them he contacted me and demanded I refund him an additional $120. Being a new seller on here at the time I thought perhaps maybe I had understated the cosmetic issues so I immediately refunded him $120 and all was good until...

A week or two later Peter re-listed the speakers using the exact verbiage I used to describe the speakers he literally copied and pasted my entire ad! Not only did he copy and paste my ad, he used MY photos in his listing and he rated them a 6/10 as I had done plus his asking price was the same as mine!

To be fair he did change one or two words in his ad description but did not go into detail as he claimed. The best part was when I discovered his ad I contacted him expressing my outrage, he then offered the profit to me!!

Then he tried to sell me some song and dance about how he was a much more experienced member here and that his behavior should not be questioned.

Feeling frustrated I started a thread about it on here but I did not mention his name, Peter then contacted me and told me to take down the thread, I of course refused so he had it removed. When I contacted the moderators they told me the reason for the removal was because the nature of the thread was not audio related. Total BS because even now there are threads about cars and climate change on here.

In the end I left him negative feedback which he tried to dispute but when I contacted the admin and showed them the two ad’s and explained what he had done along with my communications with him the feedback stuck.

So hows that for rudeness? Fyi I have copies of both ads and my communications with him, its a fun read!

You should have taken the money.  Sounds like you got screwed.  It's one thing to refund, which was very noble by you.  But then the quick sale and he makes the money you refunded him. That is shady. I would be upset like you.
Nah 120 isnt a life changing sum, taught me a valuable lesson. Just wanted to point out the hypocrisy.

Noble100, You would be incorrect to assume that I prefer bass quantity over bass quality because I’m using LSVA vs DSA. Quite the contrary, musical accuracy is my main objective(that is why I love my Apogee Studio Grands)otherwise they are plenty of powered boom boxes I would have selected instead. I also stated Noble100 because of my room layout I cannot put subs on every wall in the room for DSA but you choose to ignore that.  Since I also will be using my system for home theater 60% of the time I want the extra capability low distortion woofers when needs for dinosaur stomps. I will be utilizing Dspeaker anti mode 2.0 different EQ curve music/home theater selection for that purpose. Curious, won’t I get much lower distortion at 20hz 115db with LSVA twelve 10” woofers vs DSA four 10” woofers?!

 

flat4, thanks for the info. Yes, I will post the pics as soon as completed. Unfortunately, the last owner painted them black over the walnut veneer on the SW900’s in which I’m in the process of stripping & refinishing them. Also due to the new larger woofers I need to enlarge the woofer cutouts. Man I can’t wait until they are done & hooked up!


Looking at the audiophile (i.e. Hypex) Class D amps, they generally max out at 1200 watts into 4 ohms (with a monoblock).  Also, stability into 2 ohms is not always clear.

If you're still looking for a big bass amp, one thought would be too look at Crown Amplifiers.  I had a Crown CTS2000 years ago.  It was their "Class I" type (which is very similar to Class D).  It did very well powering a subwoofer and was stable to 2 ohm loads.  With the current product line, they have a Crown DSI 6000, which is a stereo amp that provides 2100 watts per channel into 4 ohm, or 3000 watts per channel into 2 ohm loads.  You can select the input to use a "mono input configuration", which means you only need to use one of the XLR inputs.  Street price for this is just under $2k.  The downsides are - only XLR inputs, uses a fan cooled system which means you can hear the fan when amp is under high load, and there is no trigger auto-turn-on function (complete manual power).  Just an option.
Beyond that, the absolute best amp I have ever used for subwoofer duty is actually the Emotiva XPR-1 monoblock -- 1000 watts into 8 ohms, 1750 watts into 4 ohms.  However, it is a giant beast at 99 lbs and is also a Class AB amp, and does get quite warm when driving 4 ohm load for bass.  The thing pounds bass like a mother, however.
