All speakers have different impedances on different frequencies, so "8 ohm" rating is an average. 4-8 ohm might mean that they are in this range, they could maybe also be called 6 ohm. Both amps will work. Some 4 ohm rated speaker will actually go down quite a bit below 4 ohm, and this will be a problem, and especially so for the T1 series. The T2 and T3 are better with lower impedances. As you already have an T1-M maybe you could try the T2 next?

Hi, I have the following speaker (bought it second hand for cheap): Bang & Olufsen Beovox S45-2. It says the following on the back:
4-8 Ohm, 45 (75) Watt.
My question is that which is the recommended amp for this speaker? I have a T1-M which I run on a Lenovo PSU and I quite like it. Now I'd like to buy an other amp. Should I buy an other T1-M or I should better try a T2? I'm confused as I don't know what 4-8 Ohm means. Is it 4 Ohm or 8 Ohm?
