Mike, perhaps you could update the first post with all the suitable drivers and possibly a blurb about any strengths and weaknesses,etc. smile.gif

Just a thought...it might be helpful to those following in your footsteps and utilizing your amazing designs!

Done.

Now - get the rest of these builds done and tested so I can add more proven drivers to that list.

Thanks guys. I actually have the AV15 MkII's, but if I remember right the specs are very similar to the AV15H.

Lilmike,

 

I currently am running a single F20 in my room and have been thinking of building a second sub for my room. Would the Lilwrecker play nice with the F20 or should I just build a second F20? The extra 5 hz sounds good!

Is there a difference in sound between 2 4 and 8 ohm wiring ? Or are you simply pulling more current in 2 ohm versus 8 ?

For some reason I have the notion that setting it up as an 8ohm average load would allow more accurate bass at the expense of max SPL and headroom.

Anyone care to chime in?

Are you building the second for more output, or to flatten your response?

If for more output, build a lilwrecker, it will have as much output as 2 f20s and not cost much more than adding a second f20.

Both! As part of my room redo I am building a false wall and the F20 will fit behind it and so I can put another F20 or a Lilwrecker where my current F20 is. It sounds like price wise they are going to be pretty close and might as well get the extra extension. I just got a Denon 4311 so i figured I should take advantage of its dual sub outputs. In my current setup the F20 only fits in place in the back corner of the room and i am quite sure its not optimal so I am hoping that having a second sub in the front of the room behind the screen somewhere will help the response. I just wasn't sure if having a sub that goes to 15hz and one that goes to 20 hz is ok or if that will cause issues.

Lilmike, I have a question about the lay out. The top of flare 3 is marked as 9" from the inside of the front panel. All other measurements are from the outside of the side panel.

I just want to double check that it is 9" from the inside of the front panel.

Flare 3 is parallel to the front panel, 9 3/4" from the outside, ~9" from the inside.

Sorry for the confusion.

If anyone is up or making a new wrecker, I'll donate an SWS-15D4 to the cause. They'll be my own drivers that I've beat the snot out of in my Jeep, but that just means they're nice and broken in smile.gif

I'm moving on to "new" things wink.gif

That offer stands for two people .. one each.

That's a nice offer. I have 2 wreckers that will be finished this week and no drivers yet. I'd take you up on your offer but I have never measured a sub. I wouldn't be able to give any valuable feed back to the forum.

I have been debating an F20 build but now considering a lilwrecker. Are the instructions available in different format? I do not have winzip on my computer. Thanks.

Download 7zip, it's free software....
Plus, if you are using windows 7, it's built in. Just right click and extract....

Anyone have all the specs on an Alpine SWR1542D?

It has 20.5 xmax and handles a bit more power than the SWS 15, and still quite a bit cheaper than the CVX15.

So, I was setting up the proper amp with the MicroWrecker today, and decided to see what it could do.

Stupid subwoofer tricks: Episode 1

That's the MicroWrecker, running a bridged iNuke 3000DSP for power, 20 Hz highpass in place.

Sorry bout the audio quality, my Lumia doesn't much care for over 120 dB....

Crapper... The audio quality caused me issues mentally. The candle was neat.

That left window looks crazy. Warped blinds. lol

So you need a Hpass at 20hz with this Micro sub? And what driver were you using again in the Micro? CVX?

May try and build one of these now. 240 for the Type S and a few sheets of ply.

Yeah, they sorta melted a couple years back... Since the house is literally getting torn down inside of a couple months, I haven't bothered to fix them.

I run a 20 Hz highpass cause that is as low as I can go on the iNuke. I'm leaving a few dB on the table at the corner as a result.

Only limits I have with the system set up this way are thermal, and I have definitely warmed things up.

Not sure where you're getting your type S, but I've found them much cheaper. Search around.

I live in OZ. So 129 plus 80-100 for shipping on one of them is cheaper than buying from here. Just estimates so that's why I said 240.I like the fact that I can power these with a small amp and get most out of it with only 2000 watts.(four micros)

Mike what is the suggested hpass on the micros?

17 to 18 Hz would be about perfect. Excursion blows up below there.

20's not that bad, but I am leaving a few dBs on the table at the corner.

Honestly - when the test-mule is level balanced with my mains - I am leaving more than 10 dBs on the table....

I need to get started on some better mains....time to quit messing around with subs.

Have you had time to check into the SWR1542D? I'll pul the trigger on these or the SWS as soon as you give feed back.
