Bought this today. Looks great and was on sale!! Thoughts?

Not with this fold, L45 would be too short.

Should work fine as long as the PL sticks to the LDO. No experience with PL and LDO, or anything and LDO for that matter, so I'd suggest a test joint to make sure it works.

Gotcha. Thanks for the info.

i'd say yes. gray is lab15. in room response will throw things off by more than the difference in drivers. check your cutout dimensions though...



edit: actually, i didn't change the voltage for the lab15, so the real spl is about a db or so lower the whole way across. no biggie.

thanx for the input. which do you think will perform better between the alpine sub listed in this thread or the eminence lab 15 driver? wish i could afford those high end lms subs. way out of my price range lol. this is my first bass horn build. very intrigued to say the least

post #339 of 521
nobody modeled it up yet?
post #340 of 521
here you go. sws15 in dark gray vs. stocker in light gray. no adjustment made to input voltage for minor difference in re.



so...i suppose that i'd say either will work, but the sws has slightly less ripple in the response. room effects will dominate in either case.

very nice. sounds like the alpine is an excellent driver for this build. especially for the money. right now im debating on building some waveguide monitors with AE drivers and a seos 12. wonder if this massive bass horn would match well with those monitors. i dont care if they do or not... i must build a bass horn!

If not, it isn't the sub's fault.

I'd suggest a peek at post #9. Those are JTR Triple8s, and the subs do a fine job of keeping up with them. I listen to the LilWrecker's little brother with my bottom-shelf E-waves, no complaints here either. Once the subs and mains are matched well (EQ, delay and phase), the integration is quite good.

As far as the Lab15 working in this cabinet? That's a driver I had considered for this cabinet from the initial concept, I just forgot to mention it in the first post.

Biggest issue I have with the Lab15 is that they're not exactly cheap for what they do.

According to PE, they're $280, and they have 12 mm of xmax.

$280 for a 12 mm driver? What is this, 1996? I can get 15 mm for half that $$ from Alpine, I can get 22 mm for $100 less than that from Stereo Integrity, and I can get 28 mm for nearly the same money from Fi, but they do work fine. If I had them, I'd use them, but if not, I'd probably look at the alternatives first.

I was thinking the same thing. If you have them lying around, by all means use them. If not, they are way overpriced regarding performance...
post #346 of 521

i have a pro audio guy that wants to buy these lab 15's from me. im gonna sell them and use the monies to buy materials and a new sub. so... is the alpine a safe bet or do i need to splurge a little for better output and sound quality?

post #347 of 521
"I was thinking the same thing. If you have them lying around, by all means use them. If not, they are way overpriced regarding performance..."

might want to be careful before jumping to conclusions...the lab 15 might be spec'd with overhang method only, so it's real xmax could be in the upper teens. still not spectacular, but a maybe not so bad as it seems on the surface.

True enough. Although, I thought I remember seeing the tested figure somewhere that was not so flattering. But, I could be confused as well.

Regardless of the overhang vs linear BL version of determining xmax, the Xlim is specified at 22 mm.

The Alpine SWS has a manufacturer-specified xlim of 34 mm.

Motor linearity aside, the point where the moving parts slam into the stationary parts is a place I'd prefer to avoid, because when that happens, the fun's over till the credit card comes out.

No one's complaining with the Alpines, they measured fine and perform well.

No one has complained about the Stereo Integrity drivers either.

Only issue with the CVXs is the price. When I designed this sub, the street prices were half what they are now. At the current price, I can't recommend them.

As far as I know, that's it for the drivers that have found their way into this design.
post #351 of 521

i seen several Kicker 2010 CVX 154's on ebay cheap. might be worth trying. i know what those subs can do. they will shake the fillings right out of your teeth lol

post #352 of 521

here goes one for all the JL Audio fanatics. the JL Audio 13W7. one of the most over priced subs of all time. they have done nothing with this design for over 10 years. still their high end sub. wonder if this sub will work in a bass horn. i do know these things can move some serious air. zero bottom out.

Effective Piston Area (Sd) 107.35 sq in / 0.0693 sq m
DC Resistance (Re)*** 2.41 Ω
post #353 of 521
I think the goal of all these designs is to get the most bang for your buck. The JL is priced in a category where there are much much better driver choices available for a horn.

At $1200 MSRP?

Sure, they work, but not in this design without some changes, and believe it or not, they're a little light on motor strength for a tapped horn....

I'd take the LMS Ultra and keep the change, thanks.

i use the alpines in the micro wreckers lilmike designed and they work great , the wood is more exspensive then the driver.

i push mine to the max for hours on end ( i dj with mine ) and i have yet to burn up a driver or have any compliants , and i can bet u im push mine much harder then those that are using them as ht subs

btw make sure u house/building can handle them lol
heres 6 inside a 3k sqft room not even at full power

heres 3 of them pointed into a hallway with windows for shits n giggles , u can see the windows flex

lol ive managed to break all the windows on the back of my building ( we were replacing them anyways ) i now have the new windows covered in rubber/foam pads
post #356 of 521

wow!!!! thats some serious bass!

post #357 of 521
Sub is complete. I had it built and have yet to pick it up. Initial looks from the pics he sent me are excellent. He said he watched a movie on it with a bash 300 watt amp and it was impressive. I should have it in my possession next week.
post #358 of 521
Played some 3 second sine waves at 15hz today at a very careful volume. Wow! I've spent too much time enjoying my LilWrecker and not enough time doing stupid stuff with it!!
post #359 of 521


I picked it up today. Guy that I had build it did an excellent job. Plywood with ebony stain and routered edges. I haven't had a chance to let her rip yet (too late) but I ran audyssey and so far so good. It is a monster!!!!!!!

Better pics to follow. smile.gif
