Low Frequency Rumble from TT between songs


I'm sure it's in the songs too but I'm getting low frequency rumble now that I've switched from Harbeth 30.1s to some large base reflex studio monitors. Between songs and on the lead out groove I'm getting a rumble at mid to high volume. Is that an isolation issue or something else. Table on a wall shelf, about six feet from the BACK of the left speaker, so I'm not understanding why this would happen.

@dhcod , acoustic feedback occurs at a specific frequency and is a steady tone typically described as a howl. 

Rumble is very low frequency and lumpy for lack of a better term. It is low frequency garbage for either the bearing of your turntable or the bearing of the lathe that cut the Lacquer your record was produced from. If it is your turntable it will be consistent and occur with every record. If it only occurs with some records and not others the fault lies with the manufacturer of the record. 

You hear it now because your new speakers are capable of reproducing those very low frequencies. Rumble is one of the banes of vinyl reproduction like scratches, ticks and pops.

It's definitely different on every record but still there on everything. 

I tried moving the speakers away from the table and that for sure lessens the sound. It's clearly an interaction between the two components. The bad part is we live in a small place and the speakers can't be moved and neither can the turntable. 

Are some turntable less susceptible to this interaction. I'm using a VPI Aries 1. What type of table should I try? Suspended? Idler? Or is the cartridge picking up the sound so it doesn't matter?

Do you hear the rumble just turning on the VPI player (on high volume), or only when the stylus is in the record groove?
