Just found someone who has done something very similar to what I propose.

Hi Backinblack, I'm resurrecting an old post here. Just building a pair of Frugal Horn XLs myself with Alpair 10.3M drivers. Just wondering about your running in experiences. From your earlier posts it seem like it's might be best just to leave the wadding in place until everything loosens up.
Are you even still using them 2 years on?? |

Hi Ernie,
Yes I'm still using and enjoying them. As I mentioned they do need plenty of time to break in, the recommended low level signal for ~100hrs is a good start, but careful increase of volume for the first 50 hrs or so in the cabinets is also beneficial in my view. After quite a few more 10s of hours they really begin to loosen up and the bass develops nicely. In my room I found that considerably less stuffing was needed than the design suggests in the throat below the driver. I should like to remove some of the stuffing behind the drive unit to see what happens, but as this means removing the driver and reaching down the taper I keep putting it off. If building again I would have a removable panel or top to enable easier tweaking of the stuffing. Let us know how you get on. Happy building Ian |

Thanks Ian, I finished veneering the weekend in ash as I'd like to blacken them 70's style, should look good with the gold drivers. Can't wait to get them up and running now.
How've you found listening to a single driver compared to woofer/tweeter cross over combinations? |

The imaging is somewhat better defined and more stable. The apparent width of the soundstage sometimes goes beyond the speakers physical location, but I think this is more to do with the quality of the source/recording and amplification than just the speakers. The Bass does take time to develop, it is not earth shaking but does go quite deep, this is the area where experimenting with location and stuffing will pay dividends.
They will go loud, but be gentle at first, it will be better in the long run. Black Ash, that is very 70s and not something that would suit our light and minimalist decor, or so I'm told by SWMBO! |

Just finished the XLs, plugged 'em in and put some music on. They sound great, can't believe a kit can sound this good. Hell of a sound stage on them.
And they'll inprove as I run them in? Wow. |

Good to hear that you're pleased with them.
No doubt some extended listening sessions are to come, going back through those albums you haven't had out lately. Happy Listening Ian |
