Subwoofer/s systems are an altogether separate component that should maintain their relevance through future main speaker upgrades. I'd suggest saving for a system with measured frequency control options or an outboard room optimization / equalization product with much more integration flexibility and detailed room tunable performance.
Beware of responses that include brand comparisons and fail to include the model, installation and application details.
On the other hand if those differences aren't important you should be just fine with -6dB @ 32Hz and simply reducing the crossover and gain until the thing doesn't draw attention to itself. All the best.
