Captainhemo's OB-7 Build

Captainhemo · « **Reply #60 on:** 28 Mar 2013, 06:00 am »

Hey Guys
Thanks for the info Nick, appreciate it.

Hank, yeah, I lie how the grills turned out as well. The full length with just 1/2" of baffle showing all the way around looks good I think.

Guy, we all don't have big shops and tons of tools. You'd be surprised what you can get by with.

If everything goes smooth, hopefully I'll get to fianlly hear these this weekend , sure hope so..
Basically finished assembling the first speaker this evening. Here are a couple pics, sorry about the flash

Need to tuck those wires a bit deeper into the slots. Now to do the other speaker ....

Very nice Jay! I like the color you ended of using, let us know how you like them and how the compare to your N3s you built.

Hi jay
Thats a great looking pair of speakers you've made.

What are your room dimensions that you plan to place these speakers in? I considered buying the OB7 kit to go with my LS-C, but it seemed impractical for my room conditions due to lack of the 3 ft clearance with wall. Now I'm considering buying the N3 kit.
Your listening impressions and comparison b/w OB and N3 would be helpful to know whether I should somehow make room for the OB. Thank you for the pics. Very Inspiring.

Cheers

They look superb Jay. Great job!

Anxious to read your report on how they sound and how they compare against your N3 TL towers. I am sure they are going to sound awesome. Thanks for all the pictures and comments you have posted during your build for other AC members to see.

Jay...
Great work! That's a lot of "screwin"

42 screws on the front baffle. I just can't believe how fast you put speakers together

You better slow down, your going to run out of designs to build.

Thanks for all the comments you guys, appreciate them. I was kind of hoping to be listening to these this evening but things went slow this afternoon so maybe tomorrow night.

Gijogeo, these are going in a pretty small room , aboout 19 x 12.5. It is not ideal but it is what I have so I too was worried about the size but Danny told me when he debutied the OB7's at RMAF he was in a very similar sized room and they sounded great. This build was always something I hoped to do one day but when my folks decided they wanted to buy my N3's, that just set the ball in motion.
Once I have some time on them, I will be sure to post my thoughts and impressions. I'll also compare them to my N3's for you . Speaking of the N3's being that you are considering them... I am very very happy with them. They are wonderful and like I mentioned , I really had no intention of replacing them until my folks ( mainly my dad) fell n love with them. Very detailed and transparent. I just love the Neo 3 PDR tweeters, they are so clean , bright but not harsh in any way. I am thrilled that the OB7 uses the same tweeter, if it didn't, I would not have gone this route
They also have very tight fast bass response. People are alwasy amazed at how they sound, not alwasy immediately, but after about 10 minutes or so I usually get, wow, those really do sound amazing.
Don't think you'd be disappointed in the least if you decided to go that route. I'll let you know soon how the OB7's compare

Hi Folks
The 7's are done as of yesterday evening. I pulled the N3's from the room and moved in the OB7's. I have them about 3' off the front wall and slighlty toed in. As you can see from the pics, I need to get rid of that big old Toshiba , it takes up a lot of space between the 2 speakers but it's going to have to wait for a bit. I'm sure it would be better for the sound if it wasn't there. The stuff on the wall has to go as well, it is still there from when I had the room orientated in the opposite direction.

Right after hooking them up the very first thing I noticed was the depth of the sound stage. I always thought the NB3's were good but wow, there is quite a difference with these. I listened to quite a few albums last night... Roger Waters Amused to Death, Dire Straits Brothers in Arms, The Hip Up to Here, and the Very Best Of The Cars. Today I've listened to The Blue Nile A Walk Across the Rooftops, Elton John The Best Of and Enya Watermark.
I am definitely noticing more detail and even cleaner, crisper vocals than the N3's which I find hard to believe because I was always so impressed those characteristics of the N3's. Bass response is very crisp and tight. It isn't as low as the N3's but I'd say it is definitely faster and has more of a punch. I'm sure as I put the hours on these, it will only get better ... I remember how long it took for my N3's to really break n
My mom stopped by a little while ago when I had Elton John on and as soon as she walked in she said " Oh My. this is amazing" and she was already very impressed with the N3's.. Both of us felt there was more detail and definition between the different instruments. Now both spekers use the same tweeters and the M130 so I am assuming this must be due to the OB design and also to the Platinum bypass caps I used in the OB7's. I did the sonicap upgrades on the N3's but not the platinum bypass caps.
I don't want anyone thinking I'm knocking the N3's, I'm not. They are exellent, these have just taken things up

So far I am very impressed. I'm going to put some more hours on these and then I'll make some what are sure to be more accurate comments. In any event, I'm extremely happy. so far... I can't believe I have a set of OB7's playing in my room . Unreal !!

Thank you for your impression and the photos on the OB7s jay. Glad you're happy with the sound signature. Def set me thinking.

Beautiful build.
It's amazing what can be done with a few decent tools and a ton of patience!
I am currently building a LS-C to go along with my LS-9's.
On my 8th coat of gloss poly over SA Rosewood veneer left over from the 9's.
Pics are forthcoming!

Nice job! I am envious now

Nice build Jay

My son uses a pair X Statik in his man cave and I am always impressed with the sound when I'm there. yours must be amazing indeed with the upgrades.

I keep waiting for Danny to re-design (hint hint) this model with his new copper woofers, an open baffle Neo 3, and a pair of servo 8's. Then I'm on board making saw dust

Captainhemo · « **Reply #76 on:** 1 Apr 2013, 08:00 pm »

Thanks for the comments guys. I must say, I am REALLY enjoying these so far. I have about 60 hrs on them now as they have been running continuoously since I hooked them up on Friday evening. I am really impressed. I will be posting some more detailed impressions after some more listening time

I am not sure on this but I believe I heard/read somewhere that Danny's new designs weren't going to be using the Neo 3, I'm sure Danny can clarify that. Also, when I ordered the OB7 kit, the new designs were still a ways off so I just decided to go with the OB7's . I'm not very good at playing the waiting game

Tyson · « **Reply #77 on:** 1 Apr 2013, 09:08 pm »

Try pulling them out another half foot and see how you like them. 3 feet is OK, but a bit more improves OB's a lot, in my experience.

Get in line, I am also waiting, my shop is good to go.

Very nice Jay, I am still greatly impressed with the sound of my 7's.
Happy to hear that you are enjoying them, Danny really created a winner with this design.

Yes he did !!
I was always very impressed with the NEo 3 PDR tweeter in the N3. By adding the platinum bypass caps it seems to have taken them to a whole new level
