Thanks Murata for taking us through all this, it's been quite an informative journey :)

After being through multiple setups with 8-way horns, expensive GOTO drivers, down to 3-way with AER widebander. Inlow Spiral Basshorn to ported box and then back to Spiral, I think we can conclude that you finally found the sound, that floats your boat, congrats.

There has been many inputs in this thread, to what design, is superior to the other and everybody has their own taste and choices, be it OB, boxes, horns, ported bass ect. Not even to mention drivers, dynamic, planar, compression.

My point here is, that many topologies can sound terrific even spectacular, IF implemented correctly, which is important to recognise.

You, yourself also recognised that with the Spiral Basshorn, which was first dismissed only to find out that the x-over was wrong and with the right setting, everything fell into place.

So again, correct implementation of chosen topology, is crucial.

On that note, I myself, find a correctly implemented setup of horns (I play on 4-way active with DSP), superior to other designs and it is not only floating my boat, but also rocking it :)

Thank you, Sebastian, for warm words.
Yes, implementation is important, but some limits of each approach are also exists.
Digital crossover is good to easily implement high order x-over, but the obvious limit for me is quality of DAC.
Another limit is restriction to use analogue sources.

Just discovered that thread.

Wow, that is some badass project. Congrats.

Just sold my 210-10D and my Voxativ AC-1.6, i guess we're all huntin' the unicorns at some point, is it ? :)

Try a bass line array from the top of the room to the floor.

Crossed at 50hz.

You will like it.....

I also think so, but for now I'm happy with this device crossed at 45hz with 24db/octave slope. It has some technology to control displacement of the cone, kind of feedback. It helps to dramatically decrease distrortion. For below 50hz it is really good solution.

Latest additions to the system is in electronics field:
New SE EL12 pentodes for bass region driving huge 25hz horns.
So, now I have perfect SPL down to 50hz with 3 SE pentodes driving 3 channels - AER and 2 bass GOTO drivers. And subbass managed by Velodine DD-1812 with 40hz 6th order low pass embedded crossover.
