Philips AD1255/M7full-range & AD5201s Bombardon enclosure help
Hello,
I'm wondering if any kind people can help me with making a decision on how best to utilise and to make a cabinet for these drivers. I'm fortunate in that I have 2 x near perfect AD1255/M7 full-range drivers and a total of 4 x (2 Perfect & 2 with marked cones) AD5201s/77 Bombardon Woofers.
I was planning on making each cabinet with 1x AD1255/M7 and 1x AD5201s/77. The plan was to use the Bombardon with the recommended crossover point of 800Hz and use the AD1255/M7 for the rest of the frequency range up to around 15KHz and then supplement the +15KHz with a Super-tweeter.
I have a DATs V3 and have measured all the driver parameters, I've also created WinISD driver files for all the drivers if anyone want to have a look at the driver parameters. Since the forum wouldn't allow me to upload the WDR file extension directly i've just added ".TXT" to the end of the file extension. The parameters can be viewed with Notepad as they are or if you want to add them to WinISD just delete the ".txt" part of the file extension to change it back to the WDR file type.
I'm also thinking that the largest enclosure I can get away with in the space I intend to use them would be in the 300 litre volume range.
Any help would be much appreciated.

I did wonder if lowering the crossover point would be a good idea.
From looking at the original datasheets and response curves for the drivers I made the assumption that using the higher crossover point of 800Hz for the Bombardon might actually aid the Fullrange driver, I'm not sure i fully understand why i thought that. I've attached the datasheets for from the 1968 philips catalog.
