My summer project 2008

Hello everyone,
Here are some pictures of my summer project thanks to the threads relating to 4671, 4507, 2370A in this forum. :blah:

Hey, Keith,

Nice job on you system!! Did you veneer it, or use hardwood ply, then stain? Looks great! How does it sound to you? What sort of performance are you getting out of it? Again, well done, Keith, and thanks for sharing it with us. Take care, and God Bless!

Every Good Wish,
Doc

Hi Doc,
Thanks for your kind word.

After I saw this:

I started my project. jbl/Ron made a beautiful system. I wanted the same system.
I used Baltic Birch plywood and followed this to use walnut veneer:

Then nex step was oil finish. I followed this to use Watco oil finish:

I like this system very much. Sounds very nice.

Hello keith

They look really nice. I like the glass tops. Built in protection for parties.

So which actual drivers and crossovers are you using? The cabinets came out really nice! 'Any chance of some audio measurements?

Components I used for this project are:

2 x 077 (mikey, thank you for the picture.)
2 x 2425J
2 x 2370A
2 x 2226H (John, thank you for these woofers.)
2 x 3106
2 x 3110A (John, these are from you, too.)

The system sounds very much clearer than any other system I have at home. It took me a while to adjust to obtain this sound. I get punchy LF and HF is just right for my ears. I can sit about 6 feet away and bring the volume louder without any discomfort. I have to worry about my hearing though. :D

Sheesh! 'Didn't tie your username to who I'd sold this stuff to - 'glad it's worked out OK. Ya' know- those would also be killer for a little PA, but with judicious setup, I imagine they work pretty well for Hi Fi. Maybe with just a slight tweak for VLF.

Again - 'way kool!

John

[SMKSoundPro]

WOW! Looks Great!!!

Great job!!!

I agree with John, they would make a killer little dance floor speaker box. About 8 of them around the room with a bunch of double subs for a little get-go!

What about sending me those 2226's and I will send you some 2235's and you will have a mini pair of L300's? What do ya' think?

An outstanding job!

Please post the HxWxL measurements.

Enjoy!

Scotty.

He needs the 2226 for PA use, and 2235's are definitely a better speaker for extended LF response. But then again, what you have looks like it turned out pretty nice...

Hi Scott and John,

When I was planning this project, 2235H was my first choice of components. But I soon realized it is hard to find them.
I wanted to finish the project before the end of summer any way as Canadian summer is short and my hobby room is open garage. I found 2226H at this forum. John, thank you.
My plan was to look for 2235H while I am enjoying the sound of 2226H.

I did not expect to find 2235H this quick.

Scott, I will take your offer and I will send you PM later tonight as I am still at work.

Keith

[keith141]

Please post the HxWxL measurements.

Scotty.

The size is "crossover" of 4507 and 4338.

4507 (H x W x D): 30.5 x 21.5 x 17.63 inch

4338 (H x W x D): 36.26 x 21.61 x 14.76 inch

My system (H x W x D): 36.26 x 21.5 x 15.75 inch

Based on this informatin: http://www.audioheritage.org/vbulletin/showpost.php?p=183712&postcount=19

The each panel thicknes and port length are followed.

Internal volume is easily calculated. The volume of 2370A was subtracted from the total.
I tried to keep the internal volume close to 5 cubic feet by shortening the depth.

Dear Keith,

Pm Sent!

[keith141]

Replaced 2226H with 2235H. ( Thank you, Scott.)

With 2226H, I was getting tight bass with punch, but VLF was somewhat missing.
After the change, I have lower bass with 2235H. But I felt I lost punch and slam slightly that 2226H was producing.


After reading this thread: http://www.audioheritage.org/vbulletin/showthread.php?t=21726

I closed 2 ports with Zilch Plugs, and adjusted setting of 3110A.
Now I am getting deeper base and punch which I like.

[SMKSoundPro]

Keep playing them! It only gets better.

Everything is working out and Keith's "project" speakers look great!

Stay in touch and keep posting.

Scotty.

You'll also probably have to bring down the relative balance to the horns now that you've got 2235's in there, because I don't believe they're as efficient as the 2226's were. So once you've matched the horns to the 2235's, you would then need to bring the overall volume up to match the earlier conditions, which should theoretically bring back the "punch" that was diminished...

Anyway, let us know how it goes.

Yes, that is what I did.

Sensitivity of 2226H is 97dB and 2235H is 93dB. So I brought down 2425J/2370A to match up to 2235H and also I increased 077 slightly to balance with extended base.

The result is much better than when I first installed 2235H in place of 2226H without any adjustment. I got back the "punch" I had with 2226H although it is slightly different.
I am happy with this result.:)

Keith

[johnaec]

It'd be interesting to see what some RTA EQ would finally do to that system. It looks like it now has some serious potential! 'Great work!

John

[gsb001]

Nice work. Thanks for sharing.
Fun thread to read. I have a pair of 4671-OK's with the 2225H's. Neat to see how you can mod them.
