4 ohm vs. 8 ohm for 5f2-a

[unezrider]

hello friend,
i will be sourcing parts to build a tweed princeton soon, but i have a question regarding speaker choices.

i plan on building everything as close to original spec as possible. though i will be using a 10" speaker. i'm leaning towards Magnetic Components for my OT & PT. & i see they have 4 ohm & 8 ohm taps on their trannies. does it make a difference which speaker i choose if i can source a 10" with 4 ohm's just as easily as an 8 ohm? in other words, are there any sonic differences between the two i would need to consider?
