, looking at it its hard to imagine why it cost 4K, how come did it cost that much? you got a build log of it online somewere with pics of it being built?
Most of the cost is in the drivers. They came to £2.2k. Then about £700 for construction materials such as MDF, plywood, glues, felt, lead sheet, bitumen sheets, foam and bonded acetate fibre. Paints and consumables cost another £500 and finally the miscellaneous bits such as internal cabling, connectors and speaker cable come to £500.
There's more to the speaker than the externals would suggest:
