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

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.

No resistor is best (agree with Rfogel), Duelund is a superior product to use if a resistor is mandatory.

From what crossover circuit are trying to replace the resistor from?

Mills 12 watt wirewound resistors are an inexpensive alternative and are very high quality sonically. In some places, I prefer them to Duelunds in my speaker crossovers. The Mills are also available in a wide range of 1% values.
