Mijostyn's sub array worked for me (I don't have nearly the quality of subs that mijostyn has) primarily because of my room set up did not accomodate sub placements throughout the room. (Thanks mijostyn). I also cross pretty high based on the simple premise that I wanted a speaker (sub) to "take" the "whole" instrument. A tweak that might work for those using an array is sending left channel signals to the left side subs of the array and right to the right. On many recordings, it's clear, by hearing and feel, that that double bass is clearly on the left of center. YMMV.
Springs under turntable
I picked up a set of springs for $35 on Amazon. I intended to use them under a preamp but one thing led to another and I tried them under the turntable. Now, this is no mean feat. It’s a Garrard 401 in a 60pound 50mm slate plinth. The spring device is interesting. It’s sold under the Nobsound brand and is made up of two 45mm wide solid billets of aluminum endcaps with recesses to fit up to seven small springs. It’s very well made. You can add or remove springs depending on the weight distribution. I had to do this with a level and it only took a few minutes. They look good. I did not fit them for floor isolation as I have concrete. I played a few tracks before fitting, and played the same tracks after fitting. Improvement in bass definition, speed, air, inner detail, more space around instruments, nicer timbre and color. Pleasant surprise for little money.

@mitch2 thanks for posting Townshend link, I use them with Cube speakers and imo they improve clarity. I came across this which may be of interest as well https://youtu.be/5ihzvD3urc4 |
@Derek, that is the right way to set them up as dedicated right and left channels. What crossover point are you using ? You do no want to go too high. Some harmonics coming from bass instruments are up in the mid range. Certain sounds like strings tapping the fretboard may be up in the treble. Bass instruments are usually mix towards the center so both channels are operative. You can go mono with high crossover points because you will start messing with the image to some degree. Mono is not a problem with crossover points below 80 Hz as we all know that localization is difficult below 80 Hz. The sub also do not need to be arranged symmetrically around the satellites although to me asymmetry is visually disturbing. (there's that silly brain again). For people whose woofer driver carries a substantial amount of the midrange a higher crossover is a large advantage lowering distortion in the midrange. This is typical of two way speakers. Putting subwoofers under LS3 5A's is quite the experience. With your eyes closed you would swear it was a much larger system. You open your eyes and see those little things and you start looking for the other speakers. |

This is typical of two way speakers.To achieve the reduction in distortion you described would require the main speakers to be crossed over above the low bass frequencies, using something like a high-pass filter, correct? The benefit occurs by allowing the low frequency driver (especially in a two-way) to mostly operate within its optimal range of excursion without being required to try and reproduce both midrange and lower bass frequencies. |
I just fixed my brother in law’s turntable with the same issue, but the rubber on his had disintegrated. I found these https://www.mnpctech.com/collections/turntable-lsolation-feet and installed them without any issues. |
