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

Duelund which makes better resistors anyway are available in 11 ohm. I have some in my speakers. Try Parts Connexion.Tom

Order 2 ea 22 Ohms or 3 each 33 ohms and place them in parallel for a 11 Ohm value.

Good Listening

You should keep the same resistance 11 ohms. Resistance adds in series. so yes 10+1=11. Peter's suggetion may sound better? It will be more expensive. I would go with the Dueland's if they come in 11 ohm.

I hate resistors in a crossover but if you must use them, the fewer the better.

Bite the bullet and go with the more expensive Duelands. The last thing I'd do is run more of them in series just to achieve a desired value. They may protect tweeters but they also add fine grain and often, a bit of sizzle to the highs.
