Dust covers are easily replaced. Removing the old cover is a delicate job, you don't want to cut the cone, but it doesn't have to be 100% removed.
Ok, l have replacement covers ordered, one the same size and one 3/16" larger in diameter, could l either remove most of the original cover and fit the new larger size, or just glue the larger one straight over the original. I'm wondering if the extra weight changes T/S parameters?

Extra weight will change the parameters, so the old one has to go.

I cued up all the neighbours songs, and let it rip for 3 hours this afternoon... still cant stop smiling! Finished up with Enter the Sandman really loud, the system not even breaking a sweat, the amps were still cold!
These DR280s would outperform my TLAPs, it's just hard to believe how!
My mind has been blown with the effortlessly powerful precise bottom end, and face melting clarity of the DRs
Now to finish painting.. going to spray Duratex on the T48s, l think rolling them would take forever.

See, now that's what I'm talking about. A simple, elegant, and stylish sledge hammer. I can tell you took that pic before you started playing it... the structure behind is still standing. LOL
I think anyone doing recorded content outdoors should consider a sub stack like that as the standard starter pack stack. You pretty much can't go wrong with that setup, unless you need to be able to transport your system in the back of your Honda Civic. Also happens to be the finisher stack for most too. Not too many of us would need more than that.
So jealous. I bet that was three hours of heaven. You didn't happen to get any video, did you?
I forget Keryn, how wide did you build your T48's?

In a weird way it feels quite satisfying to be able to say:
TOLD YOU SO!
Nice to see you are happy with how things are turning out. Well done mate

Honestly, I personally believe rolling 'em is faster. By the time you get setup to spray, do the primer coat, clean the sprayer, start the duratex, clean the sprayer so it doesn't clog between coats, etc......
I just wrap the roller in plastic wrap and it will stay wet overnight. No overspray. No material waste like spraying.
Now, if you have a booth already setup and spray all the time, that's a different thing. But, otherwise - I can get on primer and two coats of duratex all in a day if I need to.....and that's with drying time between. And with multiple cabs, by the time I'm through coating all of them with primer, I can start with the second coat of primer right away. I give a little drying time between coats of duratex, but it doesn't take a lot.
Either way, you can't beat duratex!

Apply Duratex outdoors on a sunnyday, let them cure in the sun, otherwise it takes days for it to fully harden.

It was mate, I thought about video, but I was too busy standing there with goosebumps and my jaw dropped!

That's a great tip Bruce, Duratex is $190AU a gallon here, & the large textured roller holds quite an amount of paint which when you wash it out seems like a waste. I would use a standard large roller for the primer, yea?

I use the 4 inch rollers that Leland sells for duratex. Much less waste and lets you get into the nooks and crannies. Here's the link to 'em.

I'm sure you can find this same type where you are. I think in all of the cabs I've done over the years, I've only thrown away one of those rollers. I wash 'em out with my spray nozzle on the garden hose and they are good to go again.
For primer, I just use the cheapest flat black paint I can get. You can slop it on with a roller or a brush.....I often use the foam brushes for the primer, then throw 'em away. The flat black dries so fast that I can start the second coat right away.

In my opinion, inconsequential mistake aside, that is the quintessential combination. It would take 9500 watts worth of amplifier and six double loaded 18" JBL's (12 drivers total) to match the long term low frequency output capability you have right there, with only four 15's and less than 2kW of amp.
Sound quality and peak output potential, I doubt there's a system in all of Australia that can match it, on a single standard (in New Zealand and Australia) 10 amp 230v wall socket/receptacle.

Really? Holy...

There's still room for another pair of each cabs on that plug!
I was pulling LF out too..
At stupid loud with a Psy Trance track playing, the limiter started to just flicker on the down beat..

As Grant would say... It's not optional. What are you using for a limiter?

I did have one.. l prefer an EQ I can adjust quickly, without having to navigate digital menus. Grant used both a Driverack and an analogue EQ, which l will do at some stage.

It's a Multicom Pro XL, which is doing the job atm
