Driver comparison: KEF vs. Boston Acoustics

[presscot]

I have an 8" KEF KAR 200B and an 8" Boston Acoustics Rally RS8 driver. I’m going to put one of them in a 1.5 cu.ft. sealed enclosure that I’ve already had. Which one is more suitable with this enclosure, please?

Boston Acoustics RS8
Fs = 34 Hz
Qes = 0.42
Qms = 2.55
Qts = 0.36
Vas = 41.0 litres
Re = 3.64
Le = 0.0
Sd = 234
Xmax = 10.2
Pe = 250 W

KEF KAR 200B (SP1330)
Fs = 35 Hz
Qts = 0.40
Vas = 50 litres
Pe = 150 W

1.5 ft³ = 42.47 litres

On first pass, Boston wants about 15 litres sealed, 25 litres vented. KEF 23 litres sealed, 88 litres vented. in 42.5 litres works well if tuned to about 35 hz.

Excuse me. Do you mean KEF or BA driver?
