How good are fullrange for movies?

[DYNABLASTERTUNERS]

and of course the sound never comes from them (just when the recording does so that you should hear sound comes from loudspeakers) it's hillarious how they dissapear

the first second I've heard them I was loughing out loud and can't stop laughing and after that I was just so

PS: they also stop babys from crying and effect is the same

My friend replaced his Accutons with the new TANGBANG W4-1757SB, and he said it was a massive improvement.

you see, but it's a strange thing that such driver and for this price and with MMS double than normal for its cone size, can sound "better" then other great drivers, so people think it's a lie or hype or something like that, because it's just unbeleivable

now excuse me, must go in the garage to finish some car hifi spheres with Visaton FRS 5X, also cheap- 10Euro per unit but good

yes, that's all very nice, but I'm just saying - that if you can't buy them, or need to order 500 at a time .....

You have contradicted yourself within minutes.

[DYNABLASTERTUNERS]

No I have not, they're emiting this dimension from start on, but with a metallic sizzle, and I knew that they will improve- so it was

Dyna blaster,


These SLS uses dual 3” crossed in 6db to a wide band monacor mid-woofer with dual opposing woofers. And the B10 uses dual 4’s (availiable in US) rolling off below 1,500hz to dual 10’s. I think they are crossing in right where baffle step is.

They are using the 3-4" drivers as 6db crossed tweeters.

The comments in the reviews report amazing tweeter dispersion. And perhaps they need all the tweet-cone output area to keep up with the massive reflective field radiation.

I like the idea of 5khz and above directional with all else omni.
Seems more like dispersion of a voice.

But perhaps the w4-1757sb needs more attention from us experimenters…………… but it ain't cheap either.
Looking at its response, it is a little hot past 9khz.

Yes, those Monacors are SPH176, and 3" TB I think are crossed at 1000Hz and wired paralel in 2Ohm

for me those are cheap, alltime bestbuy, why is that- I've allready said in my posts, they can do what no else driver can, and I also doubt that BMR drivers can do it have I mention that those flatcones image ridiculous?

[norman bates]

the 4" tang band flat sandwich

"The B10 is a 4-driver two-way with a 15uF/8Ω cap plus 6Ω Duelund graphite/silver resistor in front of the paralleled 4-inch mid/tweeters. The cap's 6dB/octave high-pass hinges at 1.5kHz to produce audible output to 400Hz. The series-connected woofers whose compact neodymium magnets are held captive in the opposing walls run wide open. Their rear emissions load into thousands of special cardboard-trapped minuscule air channels. This scheme effectively exhausts the air action inside the crammed enclosure."

What would we use to copy ?

but I found this at diyma.
"I thought that some TB flat honeycomb would be similar and the 1757SB had the smoothest impedance plots published. So I tried one but found high distortion peaks at 550Hz, 1.6k and a wide area around 10k (dark violet track). I modified the speaker by laminating the front with a 6 cm diameter carbon fiber tissue disk and coating the back of the honey comb disk with some green glue (green track).
That got rid of the two lower resonance peaks but the resonances at 10k did not change and are still very obvious in step response or waterfall plots. It would be a very good sounding midrange but these resonances do not make a good full range speaker.
Any suggestion how to modify further or any alternative speaker? "

However, I was originally looking at them for music...now, however, I am starting to wonder how they would be for movies....I am still stuck on the conventional thought that it just wont be enough for those loud hard hitting scenes in movies like Jurasic Park, The Dark Knight, Super 8....

Am I 100% wrong?

It is the low frequency that give you the hard hitting feeling of movies because you feel the lows more than you hear them. Explosions, crashes and all sound effects for that matter have many frequency components in them including lows, mids and highs. Filter out the lows and play only let's say from 100hz and up through expensive multiway speaker and the explosions will sound like fine china dishes breaking instead of earth shattering, window rattling sound that they should be. Play within its power limits, the fullrangers and a set of good sub will be plenty for those type of movies.
