Any hopes that the playoffs would kick-start Frolunda's form were dismissed when Lulea won 3-2 after overtime in Gothenburg in game one, putting the European champions under real pressure to deliver in their second meeting.
As it turned out, Frolunda came out swinging - they broke the deadlock in the 13th minute when Filip Cederqvist squared the puck in front for Max Friberg to bury, and after Oskari Laaksonen was called for hooking soon after, Cederqvist deflected a Henrik Tommernes effort into the net.
In the second period, it was more of the same, as Cederqvist was again involved before Jacob Peterson pulled the puck back for Friberg to fire home his second in the seventh minute. Six minutes later, the same trio were involved again, but this time it was Cederqvist completing his brace.
A spate of penalties early in the third period stopped the home side's goal scoring for a time being, but after Lulea lost Markus Nurmi for a game misconduct penalty, Frolunda carried on from where they left off, as Jere Innala made it 5-0 with just over 10 minutes to play.
The visitors continued to have discipline issues, as Isac Hedqvist's cross-checking was punished on a powerplay by Theodor Niederbach, and after Brendan Shinnimin became the second Lulea player ejected, Arttu Ruotsalainen made it 7-0 with still over five minutes left.
That turned out to be the end of the scoring, as Tobias Normann at the other end only needed to make 14 saves in his shutout, as Frolunda fans left the Scandinavium wondering where had this team been for the several weeks.
Regular season champions Skelleftea were 2-0 down at home to Malmo as the third period got underway, but a late comeback and a winner in the dying seconds saw them beat the lowest seeds left in the competition, 3-2.
A shock was on the cards in the second period of their first meeting up north, before Skelleftea ultimately cruised to a 4-1 victory, and many were expecting something similar, and so it was beginning to prove after the second goalless opening period in as many games.
Just as they had two nights earlier, Malmo even took the lead - 15 minutes into the second period, Linus Oberg darted down the left side before his shot deflected off the skate of Petter Vesterheim and into the net.
But then, the Redhawks went off-script, going 2-0 ahead three minutes later when Vesterheim knocked the puck back to Robin Hanzl, and he found the arriving Oberg to steer in the visitors' second.
However, in the third period, Skelleftea fought back once again, pulling a goal back in the second minute when Mikkel Aagaard set up Oscar Lindberg, and with just under five minutes to play they were level, when Viktor Grahn tapped in Jonanthan Davidsson's pass right in front.
The match looked destined for overtime, but with just 11 seconds left on the clock, Skelleftea broke Malmo hearts when Max Krogdahl found Lars Bryggman - his initial effort was saved, but he was quickest to the rebound, poking hom to win it and give the home side a 2-0 series lead.
Game three of both series will be played on Friday 27th, the day after the second games in the other two quarter-final series.
