Navin,

For open baffles have you considered the Linkwitz LX521. In couple of weeks he has an open invite at his house, for people to audition his speakers.
I am really looking forward to it

Hi Navin , I'm doing some research on room & placement.
I'm using other OB's then Morten.
Added some pics. You can see that my OB's are very "closed-in"at the side of my large conventional system.
Bad effect are not that bad at all !!
Also working on a secundo OB system.

My first setup , with cheap woofers , I posted some time ago.
A lotta things happened since then!!

I'm working with the Lowther DX3 in a PureAudioProject frame set. And 2 OB neo woofers.
I've been building loudspeakers over 50 years and this is one of the "best"; maybe most 'musical" sets I ever owned.

Wish you luck !

@jojip right now; 160/300 on the FirstWatt B5 filter. Only a cap and L-PAD on the tweeter. I will build the same filter that superlian used for his 203/500 combo. Will post some measurements later.

@navin They are out on the floor when playing music. 4 ft out and they sings.

Awesome Leonidis! Do two 15s sound better than one? How do you like the new 15" drivers?

These look lovely. I like the way back is covered.

The lyrics on the webpage seems to be google translated, or is my english so bad?

Your English isn't that bad, it looks like a mix of Google Translate and someone with a slight grasp of the English language that corrected a few things. But, that's about it.

I fully agree...As for the drivers positioning, it is nothing that hasn't been done in the past, but the aesthetics, baffle design, and finishes are simply gorgeous.

Hello, I'm just starting a horned mid , treble, and conventional woofer array.
Should I be considering the voice coils in the drivers, or their horn fronts as the acoustical centre for time alignment?
Thanks

You might need to take some measurements to find the exact launch point, and perhaps start a thread outside of the open baffle gallery to get some decent feedback.

Measurements and DSP will be your friends on such a multi-way project.

I just finished (save for making some new wiring) a new pair of OB mid range units to go with my Newform Research tweeters.
I've done preliminary measurements/adjustments but now I'm going to listen for a couple of weeks before going back to the minidsp to tune them in.
So far I'm very happy!

Thanks.
Went totally old school, popped into an Onken style cabinet, just to compare with my favourite OB.
either I got it right, or I'm completely insensitive to time alignment.
Not sure I can get used to boxy bass, but the 105 lb, 59" tall things are pretty awesome for home theatre.
OB for music, for sure.

Maybe you did, but did you try an H-Frame or Open Back enclosure for the woofer?

Currently using two Dayton RSS 265 HF-4 per channel in U Frames, which double as stands for a midrange split between a Dynavox 6 1/2", and a Bohlender Graebener Neo10, with a Neo 8 tweeter.
I got the passively split midrange idea from Mr Linkwitz's site, and it works very well.
The horns plus ultraflex idea was to hear two extremes in one room, dipoles with U Frame, and very controlled dispersion.
I enjoy both.

Does anyone know story behind this build?

Pnotus · 2016-02-17 9:59 pm

You'll find info on that on the Swedish hififorum.nu webpage
The guy that built it is nick'd Solhaga. He wasn't pleased with the sound so he did something else with the wide band drivers
