How much LF info on LPs?


Hi.

I would like to ask how much audible Low-frequency information do you get from your speakers when spinning vinyl? I know that vinyl definitely doesn't go as low as CDs. That being the case, then wouldn't speakers with good bass extension be irrelevant and a waste of money in a vinyl-only system? I've noticed that big bass=big money, in general. What are your experiences?

I didn't find this anywhere in the archives. If it is there, please direct me.

Thanks!

Try listing you complete system.

If you are experiencing a lack of bass from your TT (with a variety of source material) then something is probably mis-matched or a poor performer.

Even with small monitors (granted that they do not have a steep roll off in the LF's) you should "on a whole" be getting better bass response from your LP's.

I use old Thorens TT's (also have a TD165 -w- the stock arm that is not listed with my system) and they perform quite well in the LF's when set up properly with the right cartridge. The best bass comes from a 20 year old Ortofon cartridge (F15-EII), not the Grado Silver.

Considering that I am getting good results from cheap/cheap/cheap battery powered phono preamps and budget TT's/cartridges I think that you need to take a closer look @ your setup.

You could first try shimming up your TT mat which will affect vertical tracking angle (VTA). Cut a round (or rounds) of felt (you can usually pick up squares of it for $1 @ most fabric shops) and place it on top of your existing mat. This will lower the tail end of the cartridge and increase bass response. I only have three cartridges on hand, but all of them perform better when the tail end drags a bit lower than what the manufacturer specifies, so this may be a common occurance.

If this works then look to see if your tonearm has a VTA adjustment. I set my arm's VTA for the thickest LP's that I have and then use a shim mat when playing thinner stock.

Hopefully it will be something as simple as this.

Forgot to mention that I also use record weights on my TT's (they improve/define bass).

I made them myself by Blue Tacking a Mapleshade brass cone (point up) to the top of a 45 rpm adapter (any symetrical non-magnetic weight should do in place of the cone, just don't go too heavy). This is then placed on top of the LP @ the spindle.

Suppose that I will try some commercial weights eventually as I have found them to be effective on my TT's (don't think that they work on all TT's though, so it's better to experiment, on the cheap, as I have).

I do believe that 500 pound canaries hear down to 7hz, but as an offset they have to wash themselves with a rag on a stick.

There are no free rides.
