For my daughter's boyfriend's Christmas present I decided to build him a system. I wanted to keep costs down but at the same time come up with a good sounding system. Everything had to be re-purposed since my daughter is, ahem, really into the Green. So I set off to Salvation Army and lo and behold, a pair of Bose 301s in a sorry state. So that became the focal point of a crossoverless system. First get rid of the drivers (BTW, if anyone needs 301 drivers in need of coning, message me). I also picked up an old sony subwoofer with a busted amp.

Next, the crossovers. I only left the tweeter components, which will be used for the super-tweeter. The full range drivers are directly fed.

It is paired with a class D amp with subwoofer support. You can dial in nicely the highs and the lows. Sounds pretty impressive and looks fantastic in a sixties way..
An externally hosted image should be here but it was not working when we last tested it.

Thanks everyone.. I tried to match the VAS as closely as possible, after listening for a couple of days, I’d say it does need the subwoofer but ever so slightly. But what the super tweeter does is really important, adds a sparkle.
What a father!
You might want to double up on the 301's base, using a sheet of ply, as it looks like the one corner could easily snap off at the leg mount.

Yes, you are right! I warned them about that corner. Fortunately there is a piece of metal (that was meant to direct the foam grill) to add strength. Better yet would be a flat metal plate.
Hi. Well done! How do the ps180s sound. I selected those for my TL project with inspiration from the Baby Labs models. Still to construct.

Corner fortified with L bracket glued and installed.

You’ll be happy with them. The bass is a bit shy without the proper port. I wished the one on the Bose was longer but it does have a weird enough geometry (45 degrees to some mouth) that who knows what it does. The highs are very clear and extended. Nothing wrong with the midrange to high.
