^Sound quality is good! But I have bad hearing... Modern dsp etc. don't deteriorate sound, if used properly. Minidsp HD and younger SHD series and Hypex FA series are seriously good and transparent! My AINOgradients were voted to give best sound award at a Finnish diy meeting in 2015.

[QUOTE=robixxx1;6856909]Hi to all,


here is my system, nobaffle with acustic elegange dipole 15" woofer, b&g neo8 pdr and neo 3 pdr dipole mid and tweeter:




My spare parts speaker. I have a pair of the Neo 3 PDR and 2 pair of Neo 10, but can only get them sounding right in cabinets.
I like these in open back and folded baffles, a lot, with a sealed sub.
I use some old active 3 way crossovers .
Still rough with the "head unit". I didn't expect it to work, but I love it.

Can I ask you why? And also, what kind of baffle you have made for the woofers, u-baffle? with some damping material in the back? What crossover frequency? And where is the NEO3? sorry for all this questions... beatifull dinosaurs

The Neo 3PDR are still in cabinets with Neo 10.
I don't say the cabinet Neo 10/ Neo 3 combination doesn't sound good. I like these better, and no, no damping behind them.
I would say 3 tries at getting them to sound right in cabinets and 2 tries in open baffle was enough for me.
These midwoofers are in an open backed W Frame with wings.
I say midwoofers because they don't do bass below 80 hertz.
Crossover frequencies are 80 hertz, and 700 hertz, active 4th order.
Glad you like the looks; I'm a fan of multi purpose furnishings ��

ok, now it's clear... I've make some experiment with baffles on neo8/neo3, large, small, but finally I prefer baffleless, maybe because no diffraction... on the woofer, I've tried u-frame, with and without damping material on the backside, but finally, also for the woofer I prefer baffleless, but to work fine, the woofer has to be very special, with high spl, high xmax and high qts... I never try dsp nor active equalization, but I wish to do in the future.

Peter from PSSound in the Uk put this OB system together. Still has some more work, however it’s a great demo of what OB can do regarding bass. Enjoy.

Nice with the subwoofer as TV stand. I had an idea like that as well for a while, but never materialized, yet. Positioning of the whole is nice as well: a lot of space behind the speakers. Harder to accomplish in most household though.
thanks for the link!

Taking your no baffle preference to heart. I did fold my baffle to minimize it's aspect facince me, for fewer reflections, and have added a little acousic foam to further reduce some room reflections towards me. It sounds much more like the plain Neo 8 mid-tweeter perched atop the woofers' W Frame.
Since I'm again crossing as low as 700 hertz at times, a little baffle support is needed for my preferences.
It shouldn't be enough, but I'm guessing the woofer structure below helps out a lot.
This is as large a baffle as I want to use up top.

The 15" woofers are 1525e 4 and 8 ohm, used here as midwoofers from 150 hertz and upto 700 Hz.
The woofers used as sub woofers are Dayton RS 265HF-04, in sealed cabinet's.
