B&W Matrix 801 Series II

Elee and Linnlp12 thanks for sharing impressions. that was interesting reading.

I think the S3 tweeter was ferro-fluid filled

Yes - and it was technology brought in from success with the matrix 800 - It is the main reason the protection circuits were no longer needed and removed from the S2.

Linnlp12 - congrats on those ARC amps. I would be very interested in your impressions on using the 4 ohm taps.

I have several amps but none large enough to properly power the speakers....another consideration. My friend at the stereo shop suggests at least 350 watts per side.

The speakers are rated 50 - 600 wpc at 8 ohms. From my experiences what actual wattages are needed from a capable amp will be based on size of space, how close you will be sitting to them, the kind of music genre you will be playing, and how loud.

Wemfan - can you tell us what kind of music, and how loud it will be from your sitting distance ?

Here is the speaker impedance graph for the 801 matrix from B&W.

801 Matrix Impedance graph

If anyone contacts them at [email protected], they will send you this same graph.

Note the 4 ohm symbol on the left and frequencies on the bottom.

You can see the lowest they dip is just around 5 ohms and they do this at these frequencies.

HZ - 20, 60-100, 500, 10k and above.

So they need an amp that is 4 ohm capable (stable and powerful) in the low frequencies and high frequencies.

My experiences using maybe 8 or 9 amps ? over the last 20 years are they are a fairly easy load as long as the amp can do 4 ohms SS or Tube. You will get sound and they will go loud. But how good it will sound (smooth and musical) in the high frequencies is where the quality of the power comes especially with SS.

(i.e.) I ran with Brystons 4nrbs years ago. Great bass but the HF had me running out the door. I would have liked for the Brystons to work out as I live 40 mins from the factory.

The Classe amps (another Canadian) - very tubey sounding for SS. But lighter in the bass. Big improvement over the Bryston in the midrange and HF but not the bass.

I find when we read specs on amps they always list the 8 ohm nominal figure. Some do not list 4 ohms or 2 ohms. Ensure the wattage doubles down from 8 ohms for a SS amp and ensure the tube amp/s have a 4 ohm tap or are capable at 4 ohms - ask the manufacturer - if considering for these speakers.

Happy listening

Cheers

I made a boo boo typo

It is the main reason the protection circuits were no longer needed and removed from the S2.

should read S3.

Dave72-
As stock, probably. I have not heard them in person, so cannot comment. Again, via net scuttlebutt, some people prefer the sound of the S2 tweeter, supposedly less harsh, & some infer that the S2 w/ the NC crossover is as good, if not better than the S3.

Maybe CT0517 could chime in - Frankly, if I had the $$$, I would upgrade to the matrix 800, but that would need some serious amp power, & possibly more room than I have now.

Cheers

CT0517,
I will be able to place the speakers where they sound best from my listening couch. They will go in the studio where I have lots of room. I don't know how to tell you how loud but I listen to music fairly loud at times, mostly classic rock type to acoustic type stuff. I plan to drop by the store tomorrow and based on my conversation with the owner I will probably make an offer. If I acquire the speakers then I will need some help selecting an amplifier. It is a consignment so no telling how it will go.

Elee,
thanks for the crossover and amp info. Very helpful.

The drawbacks are...

1. 87db so I am going to need a more powerful amp than I have.
2. No bass alignment filter
3. no stands
4. crossovers need updating
5. These amps show their age. Not terrible but not good looking, either.

The pluses..

1. I was impressed with their sound in the store. They sounded very good on music and the drum track was really impressive.
2. They are big heavy cabinets and they are local so I can load them in the truck and have them home quickly without shipping and all of the problems that go with shipping heavy cabinets.
3. I think I will be really happy with them and in my area big old heavy good sounding speakers don't appear too often.
4. It seems like a lot of good sound quality for the buck.

I should know one way or the other, this week.

Hi Elee,

Ok, no problem. Yes, I have read that too. Definitely the Matrix 800. Looking back, it was a bargain at the price (I believe $15k USD) and will probably blow away the current 800 series, or at least be very comparable. Yeah, you really need to invest money in amps and cables as the 800s are quad wired.
