driver spacing versus crossover points

[slr 5000]

hi all
is there a way to calculate the optimum driver spacing on a baffle for a certain crossover point

eg ,i want to cross a scan 25w/8565 to a manger at 400hz
they will be on a baffle in a normal 2way configuration ,manger above the bass driver

is it best to get them as close to each other as possible or is there a formula to work the ideal spacing out
\
thanks in advance for any help

hi all
is there a way to calculate the optimum driver spacing on a baffle for a certain crossover point

the other way round

Ask how to calculate optimum xo point fore a certain driver spacing

well, actually its not about optimum xo point, but highest possible, with respect to woofer size and type
Then you can calculate biggest possible driver spacing
Same thing, but different words

thanks guys
what about this then
10" scanspeak 25w/8565 crossed to a manger at around 350hz

drivers are 50mm apart ,sound ok? i can go closer if needed or further apart

David Weems suggests one wavelength at the crossover frequency. but all things considered I try to place the drivers as close together as possible.

If that distance is measured to the centre of the driver then there is not much to play with.

 

[Moondog55]

To find the wavelength divide the speed of sound in air by the frequency, 1120 feet per second, or 341376mm per second, so ideal separation is less than 975mm, 50 mm is fine.

How do Manger drivers work?
Their cost has always precluded them from my shopping lists.

BTW does you handle indicate your daily drive, W/E car or a dream??

hi moondog
i was going for as close as possible but wanted to check just in case i was missing something

the mangers are well worth the money in my opinion definately different much more natural sounding than normal drivers i could not go back to a mid and tweeter arrangement after using them

yes my handle is from my other girlfriend she lives in the garage and is an original lh slr 5000 my wife calls her a money pit but i think she,s just jealous because the torana gets more lovin

I hope it's a yellow one.

Must get a listen to Mangers some time.
