lately I've seen some boxes that look the same as hd15, except that they also have the reflex ...
does anyone know what they are? |

You mean a ported horn?
Or do you mean a Hd15 with a reflex sub attached to it? If the latter that was someone on the forum who had an idea about combining the two |

yes is a ported horn (I did not know the name )
they seem to be more extended low frequency compared to the hd15 do you know if it is possible to adapt some hd15 to this design? |

Hornresp will give you the answer, it's not hard to sim a ported horn.

I finally got around to testing it in Hornresp.
But size of the rear chamber is just to small to add a port to, the response looks really bad. So my suggestion would be to go with an existing design for hybrid horns. Marc O has designed som good ones that may suit your needs. Adding port you choose "tools->chamber->rear vented." Then just go to loudspeaker wizard and choose response and combined. Then go to the chamber dropdown tab and modify port size and length to suit you needs. Good luck.

thank you very much
looking a bit from the options I was able to do the simulation, but the results are not good, now you give me confirmation I guess I will follow the advice and soon I will dedicate a new building  almost certainly a 18 " |

PavelP: Not if you want hybrid horns, MHB-46 is a good example.
But there are more alternatives out there. The ones you mentioned are just banpasshorns.
