Can Luxman 509u drive JBL Ti5000

Im newbie
I have just bought Luxman 509u to drive the vintage JBL Ti5000 6OHM/90Db ( . However the volume needs to put at nearly 10 oclock to feel relatively loud enoug.

Does it mean that Luxman 509u is a bit weak in term of driving strength for JBL Ti5000?

Many thks
Keep in mind that the position of the volume knob does not indicate the true power being delivered to the speakers. Those speakers are fairly efficient and your Luxman will have no problem driving them properly.

Don't sweat this, sit back and enjoy those great speakers!

I have 509u driving Vandersteen 5A, also need to turn know to 10 o'clock to get lots of volume, but meters indicate nowhere near peak output. It will definitely drive your new speakers.
