ZX Spectrum: HiVi M6A + BG Neo3 PDRW

Re: ZX Spectrum: HiVi M6A + BG Neo3 PDRW

Can you get the sensitivity just by looking at the response graph? i.e. if the response falls within 80 and 85db for the most part, is that also the sensitivity?

Re: ZX Spectrum: HiVi M6A + BG Neo3 PDRW

Paul: I'm very intrigued. What is the sensitivity on these?

Re: ZX Spectrum: HiVi M6A + BG Neo3 PDRW

There are a few possbilities, there: that the rendering for those files naturally smooths things by 1/24th or 1/12th octave, which would effectively eliminate those spikes (unsmoothed FR/phase look a lot like that) - or there's some logarithmic nastiness going on ..

Re: ZX Spectrum: HiVi M6A + BG Neo3 PDRW

The giant spikes.

Oh. Yeah, that does happen to me a lot. I think it comes in the file conversion. I measure in JustMLS, where the phase looks normal. Then I take the file into Response Modeler and "boost" the SPL by 100 dB or so (to bring it up to the mfr spec). Then, for some reason it gets strange values every time the phase wraps 180 degrees. Maybe Jeff knows why this is.

How bout naming the newer designs on obsolete game systems?.......

That's a great idea! Don't egg me on like that...

Odyssey, Genesis, Channel F, Vectrex, Telstar, Jaguar, Lynx, and my personal favorite--the game system that changed my life--Dreamcast

What on earth is going on with the tweeter phase? I note this seems to show up in your designs. What causes that?

Um, what about it?

Re: W A I T . . .

Yes, for all intents and purposes, you have the trademark on that one. I just had to do it this time to fit the theme. I thought of you when I did it.

And now I'm gonna try real hard not to name my speakers after ancient computers anymore. :o

How could you possibly skip the "T/S" 1000?

Not sure where the name came from 'cause IIRC it actually had 2048 bytes of ram, and didn't it come from The Land Down Under?

Re: ZX Spectrum: HiVi M6A + BG Neo3 PDRW

Nice design Paul and a fairly low component count on the XO as well. Given the low sensitivity of the M6's, a 2.5 system would really shine with those drivers.

Nonsense!

I, for one, want to build a big 3-way called "The Colossus" and a single-driver speaker called the "Zuse".

I thought *I* was the one who inverted his xover schematics?? :rolleyes:

Go

thanks for posting this, Paul. i've so enjoyed the sound of the little hivi's in the sensations that i expect to try another build soon with the m series woofers. this might be the one.

thanks again

Re: ZX Spectrum: HiVi M6A + BG Neo3 PDRW

I added the FR graph.
It's crossed just shy of 2000 Hz. Don't try this at home, kids. :rolleyes:

That's what i thought. Impressive Paul.
