Avantgarde XLR subwoofer connection

I have never been a fan of driving AG speaker this way.

I much prefer the speaker level into a sub for any 2 channel system. Especially with an UNO as the sub comes so high to meet mid. Don't you find that odd phase or textural difference annoying? You will find it hard to get decent image depth or believable soundstage that way IMHO.

Marco,

If you are in need of better bass, I would save your cash and find an amp with those characteristics you require and run the whole speaker from it.

You will have a much more cohesive sound. The UNO already suffers from the sub meeting the horn up high, so I wouldn't make an even larger difference in character by running subs with differing signal chain.

You will be in heaven when you find the right amp.

Macro,

I bet the Pass labs would sound good. Doubt you even need the 60.5. The 30.5 would have plenty of power for you.

Are you a SS amp fan? Try some First Watt too. There are many flavours.
