Sonos today took the next step in its initial public offering price, setting a range for the shares it intends to sell that will help calibrate the final amount of money – and valuation — that it will have when it begins its trading debut.

This isn’t the final, final step in the IPO process as this is usually done to test the waters and figure out the exact appetite for the company’s shares when it goes public. Sonos is offering 5,555,555 (a wonderful palindrome of a number) shares, where it will raise as much as $105 million if it prices on the upper end of its range and sells them at $19 per share. The official range is between $17 and $19, but this can go up and down throughout the process — with a drop-off signaling a lack of interest or skepticism, and an increased range a sign of heavy demand. Companies will sometimes lowball their range, though we won’t find out for a little bit where everything lands.
