x-over resistor replacement query


I am trying to replace a pair of 10W11RJ resistors, but can't find 11 Ohm units in the MOX Wirewound 10 watt Superes Resistors range I am looking at purchasing.
Would it be better to go up or down the Ohm value when replacing non-inductive resistors in x-overs, ie order 10 or 12 Ohm values? Alternatively do I connect a 10 & 1 Ohm resistor in parallel or series to get 11 Ohms?
Will these changes make any discernible difference if any?

Awaiting your feedback.

cheers

Regarding the Caddock metal film, probably not a great idea to replace a 10W resistor with a 2W one. Depending on where it is in the circuit it may be fine, but then again may not.

There are a few 11ohm options, the Dueland and also Parts Express has the inexpensive sand cast inductors in 11ohm. You can also 'make' 11ohms as mentioned, but series or parallel connection. The Parallel option would be better because you also get more power handling that way.
