So I finished putting both of the Subs that I had cut on the CNC together.





And here's a crappy picture of the two together smile.gif



I just need to wood fill everything then sand and router the edges and then a coat of paint and they're good too go smile.gif

It sure makes it a lot easier on someone that doesn't have much experience building stuff. The best part is the all of the pieces are perfectly cut to size, no need to worry about a piece being a 1/8th or a 1/16th out because you didn't account for the blade width if you were cutting them yourself on a table saw. smile.gif

Yea that will be the future route when adding more. To be honest I get A LOT already in my room with what I have. I am not sure it would be such a big improvement with a couple more subs you know. Really no space to put them anywhere but up front next to each Submersive. Although I could build a skinny tall and long cab for behind the couch smile.gif

So I finally got the last two subs setup tonight, and hopefully I can take some measurements this weekend and get them all dialed in.

AWESOME ! ! !


Stability?


Cone motion peaks around 21hz or so in your build, so hitting the subs with some 21hz "bursts" and monitoring for any rocking would provide some useful data.

Listen. It's All Good.

LOL.... that looks awesome John. I'll let you know about the rocking when I get a chance to really push them. I'll try to take some measurements tonight.


I'm actually talking with tuxedocivic about doing a DIY build for a WTW build using 15's

15's?


dual 12's have the area of an 18.


at the crossover point, subs and mains are pulling equally, so 4 + 3 = 7 18's covering bass at 80hz. :-0


BUT, if you want to go bigger...


...i support that. ;-)

I was thinking 15's because I could use the SEOS-15 and a BMS 4550 compression driver. The combo of waveguide and CD can be crossed around 800-850hz to the 15's. And just like your photoshop I'd port the top and bottom on the speaker cabinets. basically a bigger version of the JTR 228's and 212's, what are your thoughts about that?

I wouldn't go down to 800hz on the CD. 850 should be ok though.

if you are not going with something that is already designed and don't mind spending a little bit more money, you might take a look at using a larger compression driver and shooting for a lower crossover point.


paul (pnw) made a very nice speaker with the 18 Sound ND1460A w/ XT1464 horn. he might have some tips.


http://www.htguide.com/forum/showthr...-a-10-quot-MTM


with the right 15's, perhaps the 15nd930's as used in the Unity U215, i suspect that you could make one heck of a speaker.

Listen. It's All Good.

Thanks for the heads up on that compression driver, I wanted to use a 1.4" CD to start with (BMS 4593) but at $700 a piece it was a little too steep for my blood. But that ND1460A is half the price so that might be a really nice option.


How do you think the XT1464 would compare to the SEOS-15?


I was thinking about using the Eminence KAPPALITE 3015 15" driver, seems like a great driver for a good price at $260ea.
