In-wall vs bookshelf spk flush with wall

darascott · 30th September 2005, 05:14 PM

My speakers are going to be flush with a wall. I can go at least 40 cm into the wall if necessary. Am I better off with in-wall speakers that seem to be designed to work flush with the wall or would I be better off with a bookshelf design set into the wall. I heard that the crossover might need to change due to the speakers proximity to the wall. Is there anything else I would need to do to the recessed bookshelf spk to make it more suitable.
If the bookshelf protruded 2 or 3cm would that dramatically improve imaging etc?
Can anyone recommend a kit, for either in-wall or bookshelf, that would be suitable. Under $800 and suitable for a room 3m x3m
Thanks,
Dara

Given the two choices I would go with a bookshelf design recessed into the wall. I think you can get more predictable results building a box for a bass driver compared to mounting one in-wall. Of course it depends on the driver as well. If you are looking to go with a ported design make sure you place the port on the front baffle. Placing speakers along a wall results in less baffle step, therefore less compensation will be needed in the crossover.

You can always move a bookshelf speaker later.

Thanks Dave, sound advice!! When you say less baffle step does that mean no roll off towards the higher frequencies at all? What if I have them protruing slightly, say 1 or 2 inches, will I need some baffle step then? Since the room is small the sound will be very subjective to room modes. I intend to measure this. How can I make allowances for (or take advantage of) room modes in the design? Thanks again

Oh, and you mentioned that it depends on the driver. In what way?
