Both teams secured confident semi-final victories to set up to the 2020/21 showpiece at Manchester's National Basketball Performance Centre.
We take a look at both games below, with each heading clickable for live stats, plus links to live stats and live streams at the bottom of the page.
Regular-season champs and #1 seeds Solent recorded an ominous 113-69 victory over Team Newcastle on Saturday afternoon.
The Kestrels are gunning for a second playoff final win in the last three years and look strong favourites to do so after a dominant performance here.
The South coast side were firing on all cylinders from the opening tip, amassing a double digit lead within the first six minutes of the opening quarter.
That advantage grew rapidly and with 43 points separating the sides by half time, the game was as good as over.
Solent's starting five of Smith, Jackman, Okoronkwo, Arissol and Charles all recorded an efficiency rating of 21 or more, with Arissol leading the way on 27 points as he went 7/11 from range.
Newcastle have plenty to be proud of during their maiden campaign in D1, but the North East side were overmatched here despite 24 points from Ronald Blain.

Hemel will take part in their first D1 playoff final since 2017/18 after a 95-82 victory over Worthing Thunder.
Saturday's win was revenge for three years ago when Worthing claimed the title, with guard Mike Williams putting in an elite performance when it mattered this weekend.
The American has been in top form during the post-season and his 45-point outburst here was his best performance yet.
Williams' consistent flow of points helped the #3 seeds to keep hold of the lead after the grabbing it late in the first quarter, though the difference between the two sides only dipped below double-digits once during the second half.
The hosts shot 55% from the floor during their most important win of the season so far, with Greg Poleon's 22 point, 15 rebound double-double providing solid support for Williams.
Worthing's hero from a week ago Tom Ward scored 22 points, as did Max Richardson, who added 11 rebounds for his own double-double.
