Hi, Im hoping you can help a DIY noob. Im looking to build some speakers as a summer project. Were not talking about some of the beautiful DIY creations you can find on these forums and on the web but rather something that I can team with a 120W NAD C370 amp to fill a 150ft garden with BBQ tunes (and sod-off the neighbours) I realise that I wont be able to appreciate every delicate nuance at high volumes, but I want to build something that will be controlled and whilst having some bass, avoids the constant whump, whump of your typical disco P.A. Budget wise, Im looking at £250inc for the pair. Is this realistic and if so, wheres the first place I should be looking?
