I know it's nothing new and i was thinking about trying to minimise the amount of speaker in the room. Bass and mid bass drivers in the floor, tweeters mounted in the wall = no speaker cabs in the roomLindsayt wrote: ↑Wed Oct 16, 2019 7:24 pm People have done this with cinema systems. 24" drivers with the rears facing into an attic or under-floor space.
It works well. And all you need to undo it is a few floorboard sections.
You can even have the drivers forward facing with a box around them that vents the rear sound though a large hole in the floor.
Yes, seriously. Ever heard of people mounting drivers in an unused chimney breast and using the chimney as the enclosure
That's the kind of out of the box thinking we needhowardc1951 wrote: ↑Thu Oct 17, 2019 12:08 am I remember someone mounting a 2 way system of a Decca ribbon tweeter and Kef eliptical bass unit on a front panel and then over a hole into the cavity space of his living room wall.
Hi Simon. I think true infinite baffle and open baffle have a lot in common like similar drivers are needed as regards Qts but there must be differences in speaker placement. OB's need to be out in the room to work well. A lot of IB's are built in to people's walls or floors or ceilings . If built into the back wall then there is no distance to the back wall as the wall is the baffle. Built into the floor then things may not be the same .Simon Hickie wrote: ↑Thu Oct 17, 2019 10:37 am Soundstage implications are interesting. I have to say that my DIY OB speakers provide an extraordinarily big 3D soundstage that's high wide and deep - distinctly better than my semi-omnis. However, they need room to breathe with a meter or more behind them. Therefore, this would mean more rather than less speaker in the room.
Hi Howard. Can't do that i'm afraid as my cavity is full of insulation . Good idea though.howardc1951 wrote: ↑Thu Oct 17, 2019 12:08 am I remember someone mounting a 2 way system of a Decca ribbon tweeter and Kef eliptical bass unit on a front panel and then over a hole into the cavity space of his living room wall.
