Not sure...to be honest, I was just going by what I was told to get by folks here in the past. I just tell them I need grade BB, void free

Hey Chop. Do you think 4x15s were necessary in the end?

ChopShop,

As you know I have been enjoying/reading this thread since I also want to have a go at building LCR speakers with the SEOS-24, B&C 4594ND and dual 15" woofers. There was a moment when you talked about complementing the dual 15" woofers with dual 18" woofers. But instead you went for two extra 15". I didn't catch why? Just curious, nothing more: two 15" for each LCR is good enough for me since it's good enough for JBL's cinema speakers...

About the coaxial: is the x-over now active or passive? I was hoping you'd be so kind to let me copy your passive x-over. After which I can use the miniDSP to create an active x-over to the woofers.


I'd be happy to shoot a pm to you with the passive, although I'm not sure it's complete. We may end up active on the coax still as well. I actually had a good convo with one of the engineers at Danley today because I'm also picking up some of their stuff to try out for fun. The jist of our talk today was around the 4594 and getting the two sections (MF/HF) to play perfectly together because the physical unit/loyout of the coax is less than perfect and it's a real bear to getit just right. It will pay to experiment. The passive I have is nothing more than a cutoff between them though, it does no shaping. All shaping is done through the dsp. I really can't wait to get back to work on these, but the room is so far from done that it will be a while(couple months) before we tweak them in there. In the meantime, I'm sure some changes will be made heading in the right/final direction. I know people must think I'm nuts because I bought Danley's too, and in reality, I fully expect the finished SEOSR to best my SH50s, but I am intrigued by the Danley's and want to play with them too

How are things going with the mega build, ChopShop? Besides the new cabinets, have you done progress on the crossovers? Triple active is still the route to nirvana?

I am going to proceed with mine and need to decide ASAP whether to combine passive for the coax with active to the lows or triple active. The former would be my preference since it saves me 3 amps and I could run al 3 LCR of one miniDSP 10x10 HD. But only if I could make it work good that way.

Building a HT with 7.2.4 layout and SEOS-24 LCR.

Erwin I would still go for the passive 2way and active lows. Still seems like the best option. Not saying that fully active is bad just that I would do the passive/active setup myself.

Necessary is a strong word here

Not really, dual 15s would have been more than enough, but overkill mentality got the best of me and I figured, hey I'll do this once and done...problem is that I'm not done yet I really haven't messed with anything in the last six months due to priorities and the fact that the room isn't done. Matt has been tweaking for full active, to answer your questions Erwin. It's one of those things where I'm sure passive on the CD would work just fine, but enough well respected designers and engineers (who have worked with the 4594) have told me that the performance gain in the active versions is worth while. I know that guys more knowledgable than myself have made passives work great, just feel like I've gone this far, what's a couple extra amps and a minidsp or two.

Haha, thanks Chop. Yes, 'necessary' is quite a loaded word. None of this is 'necessary', but it sure is fun. Update us once you've got more done

You can get the 4594 close with a passive network, but a bit of DSP is really needed to make it perfect.
