CCB-8: 80Hz subwoofer cutoff?

[New Yorker]

Hey there, I’m really enjoying my new CCB-8 speakers. Per instructions, I set the cutoff to sub to 80hz and that works just fine. That said, I’m just curious; with their larger 8” woofers, why does this speaker have same recommended cutoff as the HB-1 MK2 with its significantly smaller woofer?

Just wondering, is all.

Good question! The CCB-8's have a bit lower extension than the HB-1 Mk2's, so you can technically set the crossover lower and the speakers would reproduce lower frequencies. However, setting a crossover at 80 Hz will give you more clean headroom on the speakers. The drivers won't have to move as much and you'll get a wider dynamic range. Generally 80 Hz and below, the bass is a lot more omnidirectional and a subwoofer would likely be better off in producing those frequencies.

Ah, I get it! Thanks for the thoughtful explanation.
