Fine looking waves Z, I love the retro JBL look. Also, congratulations on passing 10000, although they do have very good modern drugs for Obsesive Compulsive disorder
Ditto, and I wonder what percentage of Z's post are in this single thread.
It's pushing up there as well at ... oh my, another page spun off before I even completed this post.
With his "Perfect fit" Advent/2W MiniWaves now complete, Pio1980 is "Official AK E'Waver #78!"

Go to the speaker forum page, find the econowave thread, and click on the number of "replies", right now 8223 or so, and it will break down who the big mouths are!

I guess I stepped in that one, but a guy's gotta do what a guy's gotta do.

Appears so, yes.... :yes:
I'm using DE250's with the JBL waveguide and LE14A woofers.

I like the DE250 a lot. I also use the Selenium paired with LE10's and I would give the nod to the DE250's. You get what you pay for there.
Depends on which model they are, and how big of an enclosure you can use.
Some of those RS drivers have very high Qts factors... which makes them suitable only for very large boxes... given the low efficiency (88dB) and smallish magnet (17.8 oz) of this woofer , I'd suspect this is one of those cases...

Model 40-1034 and will be using Marantz 77 boxes.
Thanks for the info. In helping this newbie, what should I do? Other drivers, porting options, etc????
If I used this driver, what would the negative side outcome be?
Thanks
High Qts could also be good for Open Baffle. That might be interesting. obWave.

Please explain "Open Baffle." Are there other options with these boxes?

Well I finally got around to finishing my Cerwin Vega Re 30 E waves
It all fit really nice, the crossover screwed right on the back terminal where the old one was. It still has the fuse too:yes:
The L pad fits perfect in the hole where the tweeter was, and the grills still fit
These work as advertised, I just got these done and Im already planning a bigger better version
Thanks to all the people here for coming up with such a cool DIY project that really makes an average speaker into a great one

Those are straight DOPE!! Great job and nice looking E-Waves. I'll bet the bass response is awesome. :thmbsp:
Open Baffle is just a board a couple feet square, maybe a little bit taller than square, with a hole cut in it and the speaker mounted in that hole. The back is totally open. There are ways to figure out what size the board should be but they have a very open sound to them. Mostly run with subs though as the deep bass can be lacking. If you are not a slam-you-in-the-chest rocker, they sound great.
