Making a hole in a subwoofer cabinet smaller?

I thought about doing it this way, but I was worried making the bolts too long might make the speaker more likely to move laterally? Especially if the bolts aren't surrounded by wood on all sides for some of their length.

Sorry if anyone has answered this and I missed it. There is no need to worry about this, four, or eight, clamping bolts will provide enough force, friction, for this only to happen if you give the cabinets a righ clout in the plane of the front. That will give you bigger problems. The speaker chassis gasket, between it and the cabinet, will add more anti-slippage. If you don't have anything then self adhesive foam draught strip works well. It is basically there to elimate any minor air gaps which will affect the response of the drive unit and have been known to whistle.

Ls5/3 or Ls3/5?
I found a pair of Goodmans Ls3/5a at a car boot for £10 sold them for £765.

Congrats on the profit, but mine are Spendor

I know they were all supposed to sound the same, but...
