Nexus Media, part of Highbury House Communications, has put five of its specialist-interest magazines up for sale and restructured its consumer arm.
Model Cars Plus, Aeromodeller, Clocks, Regiment and Scale Models International - all part of the Nexus Special Interests portfolio - are to be sold off to the highest bidder.
Tom Stringer, group financial controller of Highbury House - which bought Nexus early last year - said the publisher was already in talks with a number of parties about a possible deal.
He added: 'We are rationalising the portfolio and deciding on our direction. We are looking seriously at our profitability.'
Nexus is also restructuring its consumer division. The company plans to move the music and lifestyle titles out of Nexus Media's Swanley office in Kent to Highbury House's WV Interactive Publications (WVIP), which is based in Kentish Town in north London.
Six magazines are affected by the move, including flagship fortnightly title DJ, DJ EQ - which specialises in equipment for DJs - Making Music, Disco International, Health & Fitness and Live, the magazine that caters for people involved in staging concerts.
In addition to the editorial staff, the advertising sales team of nine working on the music and lifestyle titles will be transferred to the London office. They will remain under the supervision of publisher Paul Fowler.
DJ's editorial team moved to WVIP's office when Highbury House bought Nexus Media.
Stringer said: 'DJ is the jewel in the crown of the music group. It seemed natural to move the sales team to London to join the editorial team. We then decided to move the rest of the music portfolio into office space at WVIP.'
He added: 'By splitting these magazines from the rest of the Nexus portfolio, we can use WVIP's expertise to focus on areas such as design, as well as looking at driving the magazines' circulations.'
Nexus Media revealed that none of the advertising sales employees that work on the special-interest magazines that are up for sale will be affected and there would be no redundancies.
