In a three-club deal with the Sydney Swans and West Coast, Amon Buchanan and Brent Staker became Lions on Monday morning, while the club welcomed Richmond's Andrew Raines in the early afternoon in a separate agreement.
But the Lions lost Bradd Dalziell to West Coast as part of the deal Staker deal.
Voss said the Lions' busy first day was no indication the rest of their week would be sedentary on the trade front. "We're still out there, so we'll still keep the ear open and see what's around," he said.
"Some of them are reliant on some of the other things that perhaps are going on that we're not privy to at this time.
"We'll wait and see how the week unfolds, but there are a couple of clubs that are awaiting responses and we're waiting to hear back from others on different things."
Voss said the Lions would finalise the exchange of draft picks with the Swans and the Eagles as part of the three-way trade in coming days, but it looked to have cost his club its second pick (No. 28) as part of the deal.
Raines was exchanged for the Lions' third-round draft selection of pick No.44.
Voss said the experienced injection of Buchanan and Staker – who have played 19 finals between them – was what the Lions were after.
"We were looking for a bit more experience, and we've been able to get that in those three players," he said.
"We're bringing young players into our system and developing them, so we thought it would be an ideal time to be able to bolster the list a little bit with some experience.
"To be able to add [finals experience] to our players is going to be valuable.
"We've been in discussions with respective clubs over the past few days, but to be able to come here today and get it over the line and have a little bit more certainty about what our list looks like, it's good to be able to come away from a day like this and do that.
"[The new players] are pretty excited. They've got some clarity now and they know where they're going, and I'm sure they'll look good in Brisbane Lions' colours."
Voss said the trade of Dalziell, who was one of the most impressive debutants in 2008 but battled injuries this year, had been a win-win for all parties involved.
"There was a bit of speculation he was homesick, but that wasn't the case at all, or certainly not anything that was communicated towards myself," he said.
"He's still very much in his development stages as a player, and you've only got to look at his enormous running power to see what he could add to that football club.
"He'll certainly suit Subiaco. He'll enjoy running up and down those wings, that's for sure."
Voss said the club had had a surplus of the similar types and wanted to create "a different mix".
He said the Lions had not enquired about Essendon's Andrew Lovett or Carlton's Brendan Fevola during the day one meet-and-greet in Melbourne.
He said ruckman Jamie Charman had attracted interest but would not be traded while a couple of other Lions – including Joel Macdonald – had been raised in preliminary talks.
The 2009 AFL exchange period runs from October 5-9. No trades are official until paperwork has been accepted by the AFL and formally recognised after 2pm on Friday, October 9
