Velodyne subwoofer repair

[vkalia]

Hi all -

As I start the much-delayed (10+ years... dont ask!) process of putting my system back together, I am trying to figure out if my 15-yr old Velodyne sub can be repaired and/or the driver replaced.

Anyone know if that is possible? Either via a Velo dealer or a third-party speaker builder as well.

Thanks!

Hi,
I can repair your Velodine sub driver with original genuine American parts.
1. What is the woofer size ?, / model no. of the box ?,/ and sub driver part or model no., if any ??????.
2. Do you see any parts damage ?, Can you post some pics of the sub-driver.

Hi Vivek -

Let me check this and get back to you in a couple of weeks (am out of the country right now). The sub was in working condition when I moved back to India, but it's been stuck in a box for a long time in storage for a bunch of reasons, and so i expect will need some repairs.

I'll PM you when I am back and have the info.

Btw, will you also be able to convert the power supply from 120V to 220V or should I just use an external PS converter?

Thanks!

Can you be more specific on everything ?. Which power supply ????.
Provide clear & specific detail before I can say something.

Anyways my speakers are also making waves in your Andaman's. A rental guy Raju is using my 15 inches. his mail id is ...... [email protected]

I am referring to the only power supply in a subwoofer that would be relevant to the 120V/220V discussion: the power input from the mains.

My Velo is set up to work with US voltage and I'd like to convert it to work with Indian mains voltage if I can, to avoid needing a separate box.

Is that power supply a conventional step down transformer based ?
If yes !, Then check whether they have used E I transformer or Toroidal transformer ???.
If it's E I ,Then it can be rewound to adapt 220v but you will loose efficiency. The output current will be half. Not advisable. Best effective solution is ..........

1. Get made a similar rating transformer with 220v primary in E I or Toroid from any good manufacturer.

2. If the power supply is SMPS based. Get support from Velodyne. I am sure they will provide you the correct information on the modification to the schematics to adapt it for 220v operations.

If both of these options are not practical for you. Then you'll have to stick on to the box. :sad:

^^ Good questions. I have no idea, as I havent opened up the innards of the subwoofer ever (back then, it was under Velodyne warranty).

I'll be in touch about repairing the driver coils anyway - perhaps then we can see if anything can be done about the input PS.

Thanks again.
