They appear to use these woofers by peerless and looks like they use this glass fiber midrange also by peerless. I haven’t looked for the tweeter yet, but you are about $190 per speaker, plus tweeter and whatever the crossover costs. You should be able to do each speaker for under the $330 that you are wanting to stay under.
Just keep in mind that Peerless might make some changes specifically for SVS, so they might not be the exact drivers, but they should be close.
