fsp small combo

Sorry to be a pain but could you set the volumes of the two cabs to be the same please. Say 30 litres.

The problem im having is getting driver ndl64 down to 70hz if both boxes are set to the same volume!!!!......
take a look at updated stats....

to get both drivers down to 70 to mid 70hz i had to remove both ports and increase the box volume size to 41lt!!!!!.......

this is the same setup as before but with a volume of 30lt

the responce is a lot flatter with a box volume of 41lt. with a box volume of 41lt no ports where used to get the freq down to 70 to 80hz.........

Seems to me that Bassbox Pro is confusing matters. I use WinISD Pro Alpha which may have the odd bug but seems to produce good results quickly and easily. I don't understand what you mean about having trouble getting the driver down to 70Hz or about removing the ports. You still seem to be simulating a reflex box, but without ports, so I'm confused.

In WinISD I just type in the box volume and the tuning frequency then worry about what ports are required to achieve that later.

ill try using winisd!! bassbox can be a bit confusing..... smiley29

Just make sure you get the Pro Alpha version, not the older Beta version which lacks a lot of functionality.

ok ive got the pro alpha version im gonna have a play ill post up plots later smiley16

Another tip: when inputting driver parameters, only input the bear minimum and let it calculate the rest otherwise it'll complain about consistency. eg, only input Qes and Qms, it'll calculate Qts.
