<font color="red">So it sounds like two people in the next </font>Ah, be quiet to place the blame on others?
<font color="red">Room, maybe</font>Blaming people next door? lets see why...
<font color="red">Your parents, speaking calmly about something</font>ahh, because the parents are nearby, talking...
<font color="red">Important—a lack</font> they are talking about something important, a lack of something important.
<font color="red">Of cash, the broken </font>cash... of course, they are low on cash, and something is broken.
<font color="red">Cellar pump. Marconi believed </font>The cellar pump is broken, and they dont have the cash to fix it. Marconi, could this be the same marconi that helped pioneer the development of the radio? It must be - but since we know 'radio' is poet speak for making love, 'Marconi', in this case, must be a reference to a pimp. Now this pimp has strong convictions and blieved...
<font color="red">We are wrapped in voices, that waves</font>that we are always surrounded by the urge for sexual intercourse ('voices' from the 'radio')
<font color="red">Never die, merely space themselves </font>and these urges never go away... they just get held back-
<font color="red">Farther & farther apart, </font>for longer and longer periods of time.
<font color="red">Passing through the ether he imagined </font>through a magical world of free love that the pimp thougth up

<font color="red">The frequency, staring across the Atlantic, </font>but by golly, he looked far and wide for the trick
<font color="red">His ear to the water, </font>and listened.
<font color="red">There, can you hear it?</font> and then he found the trick - it was the speaker.
Easy answer: the speaker is the prostitute getting being forced to do work in her(or maybe his) own house, next door to her/his parents, because she/he wants to hook them up with money to fixe a pump. Gosh, anyone coulda answered that easily.
