Amazing! Glad it is working out so well... wish I could give them a listen. Unfortunately I WILL NOT be boarding an airplane in the foreseeable future.

Nice! :thmbsup:
Thanks guys!!
It's a rainy day here and I have off so have been listening to them. I am really impressed just how dynamic they are. I have been doing a shoot out between my basement system and this one. This 2 way is giving my 4 way active a run for the money dynamics wise so I am having fun! I had a feeling going out flat like that would sound a bit "hard" and it does to my ears at least. I dropped a 20 ohm resistor in parallel with R7 and it makes a significant difference. The change is about -1.5 db of attenuation. The change sounds like it brings up the low end and it sounds more balanced. Much better this way! Green is normal blue is attenuated,

Nice work Rob!
:)
I've also found that "flat" may not be the most musical nor the most intelligible. While the overall curve should decline slightly, I like a bit of "brightness" in the 1-4 kHz area and it only requires less than a dB to achieve or it becomes overwhelming.
Once you get to this point, you start to consider "voicing" to taste and the acoustics of the room.
Amazing work Rob!
Have you had a chance to compare the 2453 with the 2450SL sonically?
Hello Pos
Thanks!! On the 2453SL no I actually don't have any 2450's the 476's would be the only valid comparison I have. The 2453's are going downstairs in my active set-up only going to use them above 1.5K. I even have the networks built so I should just get it done.

Been listening and having fun. Added an Impedance conjugate to tame a peak, and minimize phase angle to +/- 30 degrees. Retired the PS-200 and am using a pair of Emotiva HC-1's running with balanced inputs. Updated schematic Step, Wavelet and Waterfall .

Sorry for the confusion!!
I will continue in your large format comp thread: http://www.audioheritage.org/vbullet...ng-Impressions
It took weeks but I finally got my 1.8M resistors so I could charge couple the networks. Got them finished and they sound great! Now it's just the cabinets! Just did a verification to see if the impedance compensation worked as designed.

Been just listening. I have updated my system to include a refurbished Emotiva XMC-1 to use as my preamp in a stereo system. All of my sources are digital and I was looking for something that had digital parametric EQ and bass management if needed down the road. I also have Full Dirac in addition as an additional EQ option. I could not find any stereo preamps that had this kind of flexibility.
I have been living with the XMC-1 for about a week and it is working out very well. I have used one of the parametric band for the Q2 26Hz bump filter to extend F3 on the speakers. I still have 10 bands left per channel for room EQ if I want to use any. You can measure with REV and then import the filters into the preprocessor.
One thing that is surprising is how quiet this system is. I can't hear any hiss at all unless I literally have my ear inside the waveguide. I am running balanced connections so that I assume is helping.
Having fun!

Looking good... sounds interesting. Is it time for veneer?

Yeah it's getting close on the veneer. Don't want to break them down but I should just bite the bullet and get it done. Never done it before so it will be a learning experience. What method would you recommend for a novice??
Rob:)
Well, not having done it this way myself it seems a little odd suggesting it, but I think the most forgivable method is to use paperbacked veneer and go with PVA and iron it on.
I have used a many other techniques with both successes and utter failures... I once ruined a bunch of Brazilian rosewood veneer. It has been decades and I still get upset thinking about that one!

Now I went and did it got a 4x8 sheet of 10 mil flat cut paper backed walnut vernier that is pre-coated with adhesive so peel and stick. Getting 4x8 of flat black formica for top and bottom wear surfaces and no rings up top for an errant pint glass.
