Advanced Crossover

I Currently have a pair of transmission line speakers with 2 x 6.5 " woofers and a 1" dome tweeter.

i am currently just using a 2 way crossover at 3.5 khz.

researching a bit more, i found that other in a similar d'appolito configuration, use a crossover which enables both the woofers to handle the low, but only one to handle the mid and then the tweeter to handle the highs.

i have had a good search on the net but cant find anything like this ?

where should i start ?

cheers

By definition, this would not be a D'Appolito configuration. A D'Appolito configuration is specifically one of the MTM designs using a crossover slope and driver spacing calculated to the specifications as set forth by Joe D'Appolito to minimize vertical lobing[at and around the crossover band]. Anything else is simply a 'MTM'. What you are asking about is specifically a tapered MTM. If you used the two woofers under the tweeter, it would be commonly called a 2.5 way. It makes no functional difference if you use a tapered design in MTM or MMT configuration, btw. It is a cosmetic choice.
