What's the size of Bomb shelter?
« on: October 30, 2009, 20:42 »
Hi guys,

Anybody can help to measure and give me the L & W of the bomb shelter, and also width of the door?

Wanna see if a 60" H 40"D and 16" W cab would be able to be rolled into it and fit (imagine it has to enter at an angle). So i guess critically it would depend on 40" depth and 16" width.

Thanks!

2100,

Based on my simple drawing in google sketchup done up for my unit, inner space is ~ 2.3m by 1.25m for an S1 unit. Didn't draw the door, so cannot give an estimate.

1.25m/49 inches would be the critical dimension, the shelter is wide enough thus making the door width non-critical.  Thanks for the info man.

I have seen most shelters use cabinets that are assembled from pieces, rather than one single cabinet being moved in. You'd probably get better use of the space.

It will be an AIY (assemble it yourself) cabinet that produces high SPL bass to 11Hz groundplane....not a cupboard lah.  :)  Its a bit big, so bo bian have to store there if its long term...or during cny. But the form factor is not that bad in operation.

125dB @ 16Hz 1m GP capability. More as you move up (eg 140dB @ 50Hz). We have pretty good room gain, the response curve is just nice.

Actually I already have another smaller one but that one sure can fit.

What were you thinking, this is an audio forum, not reno talk. Haha  ;D

When Bro 2100 is done, there will be no more block left. All will be rubble!!

140dB at 50Hz!!! Most people cannot comprehend how much SPL that is, with the dB being a log scale...

There's no use hiding.... coz bass being VLF (like Radio waves) can wrap around corners...  ;D  Of course there will be more loss this way compared to straight lines...

Still softer than big ship horns @ Harbourfront

----------------------------

If you follow AVS, MK wants 2 leh. I told him 2 is more than his 8 x 18" ED (if its LMS/XXX/Mal-X esp in IB then different story lah) but he said it remains to be seen.  Waiting for Ricci and Brandon's testing.
My 2-year old TH-112 obselete liao...   ::)

not much use other than for the specific audio enthusiast/HT though.


-----------------------------

As a quick post, we played the latest Transformers almost continuously at Show East. Our demo room was many times larger than any HT discussed on this forum. The DTS10 held its own just fine and remember we had the TH221 sitting there as well! The TH221 wins hands down in a maximum output but you are dealing with a sensitivity of 103dB@20Hz and power handling of 3000 watts RMS (6000 watts program)!! I also had the TH50 and there is no question the DTS10 does everything it does but goes substantially lower. At one point I played a 15Hz sine wave through the systems and switched between the three subs. The TH50 didn't even come close to reproducing it and both the DTS10 and TH221 easily reproduced it. Fact is you couldn't really tell between the TH221 and the DTS10 @ 15Hz.
Show East is the commercial cinema show with huge movie studio participation and while I know most of these commercial rooms can't hold a candle to a serious HT, many that I spoke with are very much aware of the need for improving the audio experience as well as the HD video side. Most of the projectors being demo'd cost more than most folks homes! Danley Sound Labs' demo created a serious buzz at the show and I have no doubt we will be going into several cinemas around the world.

shelter size directly related to size of bomb. what is the biggest bomb you expect to drop down ?

Maybe should just mount the drivers in the shelter door and use the shelter as the cabinet :D
I have a pile of stuff that pushes out squiggly waveforms from smaller squiggly waveforms that sometimes come from 1's and 0's.
It's wonderful to behold as long as you don't let the magic smoke out.

Good idea, can do IB actually. But its a bad idea, coz it will look much worse than the horn.  LOL!

I got the L and W, its 2.6 and 1.6m approx. 2.8m height?  Vb = 11648 litres.  Quite big if you wanna achieve the standard 10X VAS of driver for IB.

This is mynym's Bill Fitzmaurice Tuba HT. Does not go as low like 11Hz but pretty bad ass efficiency with a mid 20s knee. (note the graph is measured with corner loading and not 2pi as in "outside")

121dB in-room, 22Hz, with just 29 watts of drive (10.8V on DMM). You could use a KT88 tube amp to drive it and still run louder than a single PB-13U with more than a kilowatt of power on tap (program).   ;D

Imagine near-field performance within the horn bubble (little-no effect from room). High SPLs, whatever distortion will be from the room, not the sub.

You could mount a V baffle and and load it up with as many 15" woofers that you can squeeze on them!

Fun but still expensive leh....  Gotta factor in the amp dollars as well, though watts is pretty cheap nowadays.

I'm running out of dynamic recordings to play....gotta find more.
