The mid-horn was the most labor intensive and time consuming portion of the whole build. Here are the flare sides cut and then assembled.

The insulation was cut in the proper shape to fill the spaces without being compressed.

Finally, here is the finished left channel sitting on the corner next to the box it replaced. I will build a case for the tweeter during the month of November. For now I am really enjoying my new speakers.

Wow, those look amazing! Great work!

I love your midhorns and your bass bins. And your crossovers look excellent too. Nice work on the crossover boxes! I do that too. It's the best way to do it, in my opinion. Some put the crossovers in the bass bin - and that works well too - but I like having an external cabinet for the crossover.

Thank you Wayne. I followed your suggestion from an earlier post when deciding where to place the crossover box. I built a regular horizontal box and added a properly shaped base, which is attached using a pair of screws and nuts.

You're an exceptional craftsman Grimsberg. Great precision joinery. Enjoy your perhaps last loudspeakers you'll ever need for the utmost critical listening.

Thank you Rusty. I am definitely keeping these for the foreseeable future, maybe forever.

How about a subwoofer? [message #94631 is a reply to message #91284] Tue, 19 October 2021 11:18 Go to previous messageGo to previous message

Wayne,

I have been listening to my 7pi speakers every day since completing them. It has been great to revisit favorite tracks and find new details I had not heard before. I am very happy with their performance but, you know how it is, we are always thinking about what else can be improved. I was wondering, is there a subwoofer which complements the 7Pi?
