Im just now seeing that Kustom made 4x12 towers!

Would it be worth my while to upgrade the speakers to something more robust?
And what would you guys suggest?
For the 2x15

Ok, this HPF vs LPF thing is new to me. Been reading g up on it.
Do these settings look close to where I should start playing loud, yet keeping everything alive?

Found a pair of us made 15s on reverb

"PMR #35PAP-SC-4. FOUR OHM/ 4 OHM wide range bass speakers/ drivers"
"400RMS/500 Peak/600"
If I wire them in series, would I then be underdriving them?

Seller is offering 15 day no questions return, I might just try 'em

From what I understand from the user manual, the crossover is just outputs to connect other amps/cabs, it has nothing to do with the internal amp itself.

Playing loud and keeping everything alive is more on you understanding and realizing the limitations of this amp/cab. The cab being 200W @ 8 ohms is a good start as the amp will probably be around that power level if it's truly 400 watts @ 4 ohm.

I don't think the drivers you've cited represent any sort of improvement over the stock drivers -- in fact, they're probably inferior to them. Add to that the fact you don't have the T/S parameters for these new drivers so you can't determine if they're a good 'fit' for the enclosure, and I'd say you'd be better off just leaving the cab as it is.

In case you're new to this, there's a great deal more to determining good replacement drivers for bass cabs than just matching impedance and power handling specs.

Goood point about the manual
Here's a link to a download for anyone wondering Invalid Link Removed

For some reason I was thinking it was 400w at 8ohm.
But this pairing would make more sense if it were 400 at 4.
