OB line array to match Apogee mid/treble ribbon

[deepmatt]

I have a pair of Apogee Centaur Minors and whilst I like the mid and treble ribbon the bass from the 6.5" isn't the best.

As a project I was thinking of building open baffle line source of woofers to go with the Apogee Ribbons.

Just wanting advice, resource etc. to help me select appropriate woofers, baffle dimensions, crossovers etc. to get the best integration between woofer array and ribbons.

Cheers

Been done by PJBlakey. I wanted to do the same to mine but came to the conclusion my room isn't big enough. I've attached a pic of his build and if I get time will search out the thread.

A few years ago, I bought some Hawthorn Audio Augie 15" as a backup/replacement for my Apogee Stage bass panels should they die, thankfully the Hawthorns are still gathering dust.

Although not a line array, its an interesting alternative; the article has lots of useful information

I think most people chose the Eminence Alpha-15A

I'm still debating OB or SLOB Hawthorns with some B&G ribbons

Oooooh I like the look of PJBlakey's one. I wonder if they sounded good. Thanks for the info guys, I'll check it out.

Cheers

I’ve been very happy with the line array portion of this project. A smaller version might work well for you. For open baffle bass you need volume displacement capacity, and probably equalization.

Matt: I would PM PJBlakey. He was posting here a couple of days ago so should pick up and respond. he was very happy with it at the time at least until the wood split.

Sorry, I just realized my post wasn’t completely clear (although I’m not sure it’s important). I meant I’ve been happy with the vertical array of six 8” woofers, none of which are really designed for open baffle use. With enough drivers, they can handle the equalization necessary to flatten the bass response without running out of linear displacement. I’ve been happy with the planar magnetic line array as well, but that’s not particularly relevant to this thread.

Few - I'm not sure what project your are referring to - is there a thread related to your project?

Thanks

Sorry for the delayed response. I just came across your post.

Yes the thread was linked to the "this" in my first post. Here it is again, this time hopefully easier to see (sorry to hide it last time):
