His plater to top plate gap seems to fetch 1cm+ which is way too high and if it's only the suspension pushing it up that high, it's not right. As is his platter will act more as a trampoline than a suspended sub-chassis and cause tracking issues for sure.
My 145 has a 7mm gap. If your gap is indeed 1cm or more, that is too high.

Hi all,
I am amazed about the response I am getting from you all. Thanks. I am currently on a safari trip around the country. As soon as I am back home I will make all suggested adjustments.

Cheers
Giorgio

Hello again! Just back from my short holidays.
Indeed the plater to top plate gap is 1 cm and for sure need adjustment. I will try to follow the instructions to adjust the gap and at the same time correctly level the plate.

In the meantime I managed to procure the HARRISON FMOD active crossover 20 HI PASS. This has practically solved the speakers "pumping" problems :-)

Cheers
Giorgio


P.S. to: McLaren007 & tlscapital. Which photos you're asking for?

Did you try the Subsonic 15 Hz filter switch on the Pioneer A9 amplifier?
If you use it, you may not need the FMOD crossover.
I would worry about the FMOD crossover putting strain on the RCA jacks of the amplifier due to the weight and length of the FMOD.

Keep us posted on your suspension adjustment. I was just pointing him since he asked for your photos with the 1 cm gap between your platter and top plate as shown on page '2'.

Hi,

Subsonic 15Hz filter switch on Pioneer A9πŸ€”?
Didn't even know it existed πŸ™„.
Will check the manual then.

Hi all,

could not find the famous subsonic 15Hz switch on the Pioneer A9.

However, I tried to adjust the suspension and...not an easy work indeed. To find the right adjustments and balance on the three springs to level the plate, adjust the height and at the same time have it "floating", was somehow hard. I am not completely satisfied of the results though it is better than before but, at a certain point in time, I preferred to stop it there.

cheers
Giorgio

Next to the source selector switch.

I've not read all the posts here, but if you've got the Pioneer A9 did you know there is a flap on the left hand side? Open it up and there's your subsonic filter! It's just to the right of your rec out selector. Here's a picture I found with the flap completely removed.

Possibly...try to stuff the insides of the suspension springs with soft foam...?

Hi Lazarus Short,

I send you a picture of my Pioneer A9 amplifier. As you can see it's totally different from the one you sent me :(
Indeed I cannot find on my A9 any subsonic filter switch...
