NSB center channel. Do I need a tweeter?

[GuyPanico]

After I finish my NSB line arrays, and if I find them to my liking, i'm going to make a center channel as well. Using 4 NSB's. I plan on coating the cones and making a phase plug for them to help out the highs. My understanding and experiences with center channel surround is it mainly just covers voices. Not very much information down low, or way up high. Could I get away without using a tweeter? I'm going to make the center sealed.

It's DIY, you can do anything you want. There are no worries,
it's not as if you are back in World War II making a sound system
for Hilter and if you fail, you get shot dead.

Hold a modded NSB in your hand and play some music, do you
like it ?

NSB with cone treatment and phase plug sound pretty nice
full range. 4 - 6 coats of lacquer or equivalent.

I think thylantyr needs to change his name to represent his knowledge of the NSB driver.

This might deserve its own thread.
I'm way off topic. Sorry. Delete me if needed.

Phase plug and laquer it is. How do materials and shapes effect how the phase plug operates?

someone needs to write a really fricken good guide on how to make phase plugs...

You can use minwax wood hardener instead of sanding sealer and
I mentioned in my post.

The NSB was a project for a friend, I normally don't play with
49 cent drivers

Because they are so cheap, experimentation is easy.

Now, Now, don't lie Thy

Seriously though, good work on the NSB's. I think you more than anyone has extracted the most from these drivers.

Most of us just buy drivers and never consider nor know how to mod them, let alone actually make audible improvements.

The only real mod that I know of is removing the grill covers

any chance you have the ability to measure a non modded versus a modded nsb? i'd be very interested to see what it does to the graphs...not just listening tests

[GuyPanico]

Can anyone see any problems with this setup? I use 4 NSB's front fireing, and 2 NSB's rear firing for the center. So i'd have dipole speakers, and a bipole center. Or would a dipole be undesirable as a center? Dont they have a very unlocalized sound? Suggestions needed

I built a similar speaker last year.

We are doing a project like this right now. I have twenty Sea Scouts building bookshelf speakers using the PE Pioneer buyouts mentioned above and the Dayton neo tweeters (PE#275-030). They are organized as MMTMM and will go in a .75 ft^3 ported enclosure with folded miter & rabbit construction. Oddly enough, the price will be about $30 for a pair.

They are very nice sounding and the Dayton neo tweeter is a good match for the 4 NSB's.
