Has anybody tried putting a insulation in their tender? In a speaker cabinet you use that to get a better bass. Any thoughts?
One foreseeable problem with this is that you’re cutting off the air circulation around the decoder, and sound decoders especially need lots of air circulating around to keep them from overheating and burning out.
I’ve toyed with the idea of putting some fiberglass insulation behind the speaker when there was no room for an enclosure, but decided against it because of the risk of the insulation poking holes in the speaker diaphragm.
Good point, no room for a muffin fan !
Sound absorbant material is placed in speaker enclosures to absorb a specific frequency and tune the cabinet. The frequency attenuated is dependent on the thickness of the absorbtive material, for example, a 4 inch thick batt will soak up lower midrange frequencies you’d expect too much of in cabinets the size of home speakers.
What you could fit into an HO tender would soak up high frequencies. At that rate, I’d want the material in front of the speaker. By soaking up some upper mids and highs, and turning up the volume, you’d increase lower midrange frequencies and widen and flatten the frequency repsonse, but probably not down to frequencies anyone would call bass.There’s just not enough room in there for bass.
That is what I like about this forum, ask a question and get a real answer. Thanks all.
