Re: Maurbacs NS6 MTM

The 100w will be plenty. The 300 will be more than the ns6 will be able to handle.

Im not sure if what I'm thinking is right, but when I saw the power handling for both the NS6 and the Vifa, I noticed that the RMS value was 50W. All three drivers are set in a parallel circuit, so if supplied with a total of 100w, each driver would only get at MAX 33 watts. Thats still below the RMS value. I saw that the max power handling for both the NS6 and the Vifa was 100W, so if I use a 300W amp, each could POTENTIALLY get 100W, even though I know i'm never supposed push it to that point (not like my psu can supply that much power anyways). Also there's plenty of overhead space for less distortion from the amp.

Is it just the fact that the NS6 can't really handle anythign above its RMS power value? If anything i said was wrong, PLEASE EDUCATE ME cuz i dun wanna blow anything up

Re: Maurbacs NS6 MTM

The amount of power the NS6s can handle is dependent on your box primarily. If you can put up your intended box dimensions I'm sure someone will help you figure out exactly what you can throw at them before they distort beyond usefulness. Generally you will run out of excursion/xmax in the NS6 before you hit the wattage limit. In my Maubacs build the speakers were very loud with only 25 watts on them, and were nearing my comfort level on the xmax at that same area as well.

Thanks Adam. I agree totally. I've been hampered in this design by not having a good value for xmax.
I even looked it up in a couple of references, and still could not derive it.

You're right, and you're not right.
In terms of basic power equation, you're ok - but real world speakers have xmax, xlim, and short term and long term power
handling capabilities that are pretty much impossible to get around. The very, very basic equation involves
SPL output, efficiency, bass output desired, and the size of the driver(s).

WHAT THIS MEANS IN THIS DISCUSSION:
The 44 liter box will let the Maurbacs play into the mid 40s or so, but not at a "party" SPL.

If you need and want that level of LOUD, I strongly suggest you build the Stentorians.

Not much more money, but will play very loud. Everyone who has built them is very happy.
And to recap this discussion back to science and engineering, the Stentorians have 6 x NS6 drivers per speaker
for a much greater surface area and efficiency, and don't play quite as low as the Maurbacs. A good, clean 100 watts
per channel will provide very loud music for you and your friends.

Re: Maurbacs NS6 MTM

I will most certainly look into these! Thank you for all the help guys!
Access to a CNC should most definately help me too.

Re: Maurbacs NS6 MTM

yeah i had bought the dx 25s, and ns6s for a different project but scraped that plan and ive never designed a crossover. how hard would it be do design a crossover using the dx 25?

Re: Maurbacs NS6 MTM

Don, I'm looking into building myself a center-channel which my TV can sit on, and I was considering the Maurbac. I wanted to know how you feel about yours, if you've made any tweaks to the crossover or anything for use as a CC, etc. If you think there's something better for the money steer me that way.

No, crossover remained the same. I did make the CC sealed, and with an 8 inch baffle width (height, for a CC).
Sounds great. Surprising bass.

Re: Maurbacs NS6 MTM

Hi Don,

I'm getting back into speaker building, haven't done any in years and have fastened on the NS6's for all of the obvious reasons and was attracted to this thread. Have you or do you know of anyone that tried a TL concept instead of the port with your basic design? Or is the probable answer that this is a more difficult thing to model and execute successfully compared to the port? Or given that, how about a slotted bottom mounted port?

I haven't done a TL, and neither has anyone else as far as I know.
Someone has just sent me very nice cad drawings for a tower version - that should be pretty easy to convert
to a slot port if you'd like. If you're reallyl set on a TL, I might be able to get one of the TL experts here
to model it for us.

Re: Maurbacs NS6 MTM

Thanks for such a quick reply. I forgot to mention that a tower is really what I am loonking to build so your comment is opportune. I find the concept of a TL intriguing so it would be nice to have the option if someone is willing to model it that would be great. I'm not concerned about making it taller, larger other than keeping the front baffle to a minimum width so I'm pretty open at this point. I imagine the slot conversion would be fairly straight forward, isn't there a conversion factor for it if you have an existing dimension?

Sorry this was a silly comment:

Of course the conversion is by equivalent area, but you need to know the dimensions of the box to decide on the width then determine the height, although I seem to remember some small differences in how air flows through a round vs square tube that could bend the result.

You can find calculators on the web for conversion from round ports to slotted ports.
Some Windows programs will do this for you - WinISD I think.

Re: Maurbacs NS6 MTM

Im building a set with 4 NS6s and they have plenty of bass. Not a bad woofer for $9. Have not broke them in yet, but soon. Enclosure is probably smaller than what some might say they need, but they are nice sounding so far
