discussion boatman's 1/72 HMS Tiger C20 build

[Tim Marlow]

No need to be nervous Chris. Your application of logic and talent for the build will see this one through no danger.

HI YES it all worked a treat but ive got to fit on the 12 watt speaker as the 3 watt not powerfull enough only trouble its heavy an wheighs in at 12 ozs but i will fit it in the centre of the deck so no rolling probs but wont really know till she's on the wet stuff but tommow i'll be fittin in the spks into the deck so gonna be busy

Is that the right way to go Chris? Are these speakers active, powered by their own amplifier, or passive, powered by an external amplifier? if they are active then you are doing the right thing, but if they are passive, then possibly not. As I understand it, wattage in a passive speaker isn’t the volume it can put out, it is just the maximum power it will handle. A passive speaker will need a more powerful amplifier to sound louder.

In HiFi, the statistic that matters is the efficiency (usually a percentage) of the speaker. A higher efficiency means the speaker turns more of the operating power into noise. In two speakers of identical efficiency 30 watts is twice as loud as 3 watts, by the way.

Another option is to fit the 3 watt into a box and then fit the box into the ship. A bit like a music loudspeaker. That way, all the noise is projected to the front of the speaker, focussing the output and increasing the perceived noise it makes.

WELL Tim all i can say is that the gent who built the unit said there is an ampliflyer in the gun unit that will up the power of the spk an im very happy with how it sound an it will be better when built into a spk box to ampifyi the sound

HI GUYS well a bit more done on this gun fire unit an the main 12 watt spk bein fitted in in the deck S/S HERE just fitted it for size to see if it will go in ok

 

[boatman]

AN YES it will fit so ive started to build a spk sound box to get the maximim bangs

 

[boatman]

an bottom of the box built in but the spk can be removed an there is also the whooper sound unit an spk as well

 

[boatman]

an top view of both spk just got hope they are not to heavy

 

[scottie3158]

This build has so much going on mate. Is it still going to float

 

[boatman]

an now covered with the spk grill

HI Scottie well it could be a titanic but ive now picked up the rear end section an i can just lift it so yes its possibe but the gun fire unit wont be any good without the spker will it an its just as well the gun unit is fairly light which will be fitted in tomorrow an then its should all work but the big guns only as the small will train an elevate only

 

[boatman]

an side view an tomrrow the big funnell an fan unit will be fitted back on if the gun unit is all ok an yes all this build is headdin towards the finish line an with this big sound box it should bang good
