Re: Coils n' caps and X and overs - DIY crossover for newbies

I used to wind my own coils, because there was no place to buy them. The last time I did so would have been around 1985. I've always used caps made for audio. There are some things where making your own makes sense, like speaker cabinets. Some don't, like coils, or using caps that aren't spec'd for ...

Re: 4 DR280 and 2 titan48 for a record store/venue!!!

Just stack them on the subs, Blasphemy. The sub placement as it stands is poor. They should be spread wider, and pushed back further, making them tight to the side walls and as close as possible to the rear wall. The only time mains should be stacked above subs is when there are no boundaries, whic...

The only engineer that matters in this case is me. The DRs aren't designed to handle the weight of being hung. To safely hang them requires an external rigging that puts the load on the rigging, not the cabs.

It is not the way to do it.

Wrong. It would be 8 ohms below the crossover frequency, 16 ohms above it.

It is. In effect it's a bass trap.

Sacrificed some rear visibility but car has a rear camera. The rear view mirror in my BMW might as well not be there for all the good it does. I installed one of these:https://www.amazon.com/dp/B0855GMKMD/ref=sspa_dk_detail_2?psc=1&pd_rd_i=B0855GMKMD&pd_rd_w=B3iHO&content-id=amzn1.sym.f...

Re: Truck Tuba first impressions….

Glad it worked out for you. As for the sound deadener, if it needed it the plans would say so. Car doors need to have added mass to control vibrations because they can't be braced. Properly braced cabs don't need added mass, and they don't need to be made from 3/4" material. 1/2" with even...

Re: Finally! Omni 12 Tall Boy build

The 10uf cap I installed in series earlier in the build that I thought was to protect the tweeter from errant frequencies that could damage it. I doubt that it's damaged. Caps tend to either work fine or not at all. You've got clipping somewhere. It could be the amp, could be the source media. Clip...

Re: a T48 + a simplexx?

The only ones I use them in, bass reflex subs. What it comes down to is which do you have more of, pack space or money? If it's pack space build horns. If it's money build bass reflex. Bass reflex requires at least twice the number of drivers and at least twice the amp power to drive them, so you ne...

Re: Super compact tuba for very small gigs - T18 or AT?

6dB less than in a corner. Away from a wall 12dB less. Then there's the matter of a driver able to handle the job. They're out there, but they're not cheap.
