That plywood sure looks like it has a thin veneer.....hopefully, that's just the pics.
it's not :(
Then I'd suggest that you leave all of the screws in the cabinet.

Re: Maximizing pack space and performance, under budget.

Most of the time I run the full rig, but there are also many times that I only take the car. I made a cardboard mock up and at 20 inches I can still fit one in the back of the Buick with two DRs in the trunck. I guess I could make just one slim one and not a pair? If you build one slim - build two....

Re: Maximizing pack space and performance, under budget.

Performance wise, maybe it's a toss. The gospel per the plans state the lab has higher VD, and that you should go with the highest VD you can afford, plus the SPL page showed the lab having a little more output, bit that was due to the labs lower impedance. :wall: We need a side by side compare. Wi...

Re: Maximizing pack space and performance, under budget.

I feel like it's been stated more than once that the Lab is not superior to the 3012, just a (formerly) lower cost alternative, but I don't recall the explanation as to why. The WHY was because neodymium prices went through the roof. That's why Bill re-designed the T39 and added the Lab12 to the mix.

Re: Maximizing pack space and performance, under budget.

Hey J have you considered the 3012LF? If I remember from the plans they are both limited to 50V and saving 14# per cab would be a plus. I think the lab12 was a consideration when the price was lower than the 3012's. Now I think they are less than the Lab 12's +1 Yep. $5 cheaper and a lot lighter.

Re: Truck Tuba Car Sound Quality Questions

Does the driver sit vertically in the Truck Tuba? I.e. Will I need 10+ inches of vertical height for a 10" subwoofer? I have 8.65 inches maximum available height. I have about ~37 inches of width available across the cargo area and ~24 inches of depth, front to back in the cargo area. Thank you! Th...

Re: Capacitors and Inductors and Bears....oh my!

All low pass filters use non-polarized electrolytics. All high pass filters use polys or mylars. You could use polys in low pass, but they'll cost more and won't work any better. The difference between 2kHz and 1.2kHz filters is the component values, not the components used. That clears it up a lot...

Re: Capacitors and Inductors and Bears....oh my!

So, is the reference to electrolytic caps just boiler-plate in the general crossover info and they aren't actually used in any of the crossovers?

Re: Capacitors and Inductors and Bears....oh my!

Mmmm, Brown Bears. No, Black ones. Grizzly maybe... I would be surprised to find the same conditions for the 2K crossover weren't the same for the 1.2K, so poly or mylar. Get hold of Leland, I'm sure he is all over it... The problem is that Part Express breaks 'em up into two categories - Metalized...

Capacitors and Inductors and Bears....oh my!

I’ve always bought my crossover components from Speakerhardware.com, so I’ve never worried about trying to source them elsewhere. However, I might be making some changes where I just need some components and I’m struggling with the verbiage in the plans and what I’m finding available. The inductors ...

Re: Crossover and limiting a Tuba 30 with Nady PTS 515s

The tweeters had been blown previously by my buddy Just be aware that on low quality speakers like those, the driver in that horn is probably really small and cheap.....so, be careful of boosting the highs much - especially at the crossover point. Of course, finding a spec sheet on those that gives...

Re: Crossover and limiting a Tuba 30 with Nady PTS 515s

You don't really need to limit those tops as they will start barking if you get too hot. If you are just worried about blowing 'em, then I'd limit 'em to about 25-30 volts. Based on their rating at 8 ohms, they should take 40, but I wouldn't go there. You aren't going to be getting stupid loud with ...

I have a DBX DriveRack PA. It only has XLR ins and outs.
As it should. Mixer to Driverack via XLR (mic/signal cable). Driverack to amps via XLR (mic/signal cable) . Amps to speakers via Speakon (Speaker cable).
