High output, multiple driver DIY main recommendations? - Page 11

Thanks for the suggestion Matt ! No worries suggestions/critique is always welcomed here. The mids sound great so far, but I do have some extra polyfill I can try out to see if makes an difference to my ear.

Heh, the clip lights were barely just being tapped, but you could easily tell the amp is/was holding them back. I do have my Crown XLS5000 sitting around that I could try out. That will definitely give them ample power. Nervous?

I'm running Audyssey now and plan on watching the first movie with this setup right after. It will be cool to see how they integrate with my subs too.

Thanks Brian! I'm enjoying staring at them right now.

It's clear they can take a lot more than the EP4K can dish out. The clip flights start to flicker at crazy levels and there isn't the slightest sound of stress from the mains at that point. As I mentioned above I could give the Crown XLS5K a try? I had them crossed at 40hz earlier.

Thanks Scott - more impressions coming up.


Thanks Carp! I will have to check the specs but I believe mid to upper 90's sensitive?

Edit: Erich's site shows 96db. This seems about right based on the audyssey settings.

Just got finished watching most of the avengers. A few more comments:

I ran audyssey and now have the front 3 crossed at 60hz. Audyssey set them at -9 which is very close to where my sho's were set. During most of the movie I had the volume from -10 to -5.

Clarity is exceptional. What stood out most for me was the center channel's dialog. Even with my center sitting on the floor under the screen, the width of the stage was great. I really see no need to move the center from where it is.

Dynamics: in this movie there are quiet a few scenes that go from very quiet to huge peaks in a split second. This setup handled them with authority. The many gunshot scenes sounded eerily realistic too.

Looking forward to playing alot of music on them tomorrow and just enjoying them in general. I will post some SHO vs. sentinel comments after I've listened for a few more days.

So far that's about right. To be honest I never really noticed any harsheness at all with the SHO's. I'm sure there is quite a bit less distortion with the Sentinels at those 'spirited' over reference listening demos. Midbass and extension is not even close, the Sentinels slay in that area. In all fairness the B&C 15 is about the same size as the entire SHO speaker, LOL. The cool part is the Sentinels extend much lower, and don't really seem to give anything up in the senstivity department. I still think the SHOs are unbeatable for a finished product at anywhere near that same cost. The deltamax is an even better value for those willin to DIY! But in my opinion the upgrade to the Sentinels for ~200 a speaker is a no brainer if you've got the room for these beasts.

Overall soundstage width both are excellent. When combined with a proper sub setup, I'm sure the Delta max or similar would be pretty awesome for 99% of the guys out there. The Sentinels take the mid-bass impact to a new level though.


For the next few days I'll leave them hooked up to the EP4K. I will experiment with more power later on once I have some hours on them and broken in.

BTW I wanted to send a huge formal THANK YOU your way for all your help over the past few weeks. I look forward to working with you on future uber creations too if you're up for it.

Thanks Scott! Time to get some hours on these babys now. How is your UBER mains project coming?

Thanks Kevin! I love the slot port look to and in this case I didn't have a choice anyway as it was the only way to fit these under my screen.

Thanks bud!

Thank you sir. The SHO's are about to be listed in the for sale section.

Some more thoughts - listened to the majority of 'Dark side of the moon' almost twice this morning. I moved the LP up about a foot and played with toe in a bit more. Sounds fantastic - the best I've heard this album sound anywhere in my house so far. I found that the best sweet spot is about 6 inches higher than where the speakers are currently sitting so I'm going to build some small stands for them out of my plywood I have laying around. I'll coat them in duratex to match as well.

Like Erich said the 29.5" normal version should be great for you. The original version has 3" circle ports.

Thanks - I had intended to make stands from the beginning, just wasn't sure which size I would make them. For the center channel I'm going to make a small 45 degree wedge to angle it up toward the LP.

Actually originally I had them at 40hz but the music I was playing probably didn't quite have content that low. They could definitely benefit from some more power eventually, heh.

GET IT!! We expect program update by tonight.

Only a matter of time before I broke the omnimic out.

No subs, B&C's full range, 1/24 smoothing, post XT32 run, from the LP 18 feet away. Extension was the same without EQ, but I did have a good sized peak at 100hz. Check this $hit out! Extension to 19-20hz. BTW I also ran the sweeps up to 110 where the sweep looks exactly the same. Thought I grabbed one of those too, but I guess not. Any more output past that and the omnimic gave me a mic overload.
