If I remember correctly for every 3db increase in volume you will need to double your amplifier output power. So with 91db efficient speakers you should be able to get up to 106db peaks with your current amplifier.
As a point of reference I believe that general conversation is around 50 - 60 db and if you are yelling at some one or vice versa, you will be around 85db.
You should be fine with your current amp at low to moderate volume levels. If you are unsure turn the volume up slowly until you hear noticeable distortion. Turn your volume control back a click or two and this will be as loud as you can play your system. If not loud enough then you will need a more powerful amplifier and you will need one in the range of 250 wpc or larger.
