Hi guys. If, like me, you have the misfortune to own an ashdown rm 115 cabinet do yourselves a favour.
Remove the grille.
Unscrew the 15" speaker.
Marvel at the assortment of screws used.
Get some old clothes/ sheets/ clothing.
Stuff the cab above the horizontal brace full with said sheets/ clothing.
Reassemble the cabinet.
Violla! No longer does it sound like a flabby pile of dogmince.
Thank you.
