I am not at the moment, so I had to listen myself. But I know I will need something to measure higher frequence. I want to see how much the baffle step affects my listening, I have heard alot about that, maybe that frequence sweep I talk about can give me a hint.

There is enough baffle step compensation integrated with the crossover as it is. If you will need more you can up the woofer coil in steps up to 3mH and tune to your room/liking as I had explained in the past posts. In general your subjective chart looks smooth enough in the low bass. Expect some weakness in the upper bass due to floor bounce and type/positioning from base standing regular size two ways.

Ok, that explains why it seems to have no big baffle step effects to my ear, it sounds pretty neutral over all. If I am not wrong you said it did not have a baffle step compensation in the original thread "the secret of building a good 2-way".
Maybe you meant it has not got the common way of dealing with that but like you said, it is integrated in the over all design.

I don't remember, have to look to those posts. Maybe I had wrote that it does not have to have a discrete baffle step shaping portion in the crossover? In most designs the baffle step compensation can be integrated into the main woofer coil if the curves aren't particularly rebellious. In BBC LS3/5A crossover you can see a wide Q trap and shaping part for instance. Due to the 110A woofer having a special hump because of Bextrene quirks. That were changing with raw material batches through time for that matter.

Well, it is not so important but it was nice to hear it has a compensation, makes you sleep better at night . It sounds very good and that is what matters. I will test listening to the port only and hear how much the bass reflex sounds at different frequency, if I remember correctly that 135mm is tuned at around 35Hz?

P.S. Most important issue still lingers! In what color are you going to paint them?

Post #175 impedance saddle midpoint shows 34ish. Correct.
