Roger, down the rabbit hole I go again, I've given up worrying about the cost of similarly specced anything down here these days man!
Haha.

Roger, that makes sense :idea:

In this thread it's mentioned the Penn Elcom 1105 handle projection into the horn path of a DR280 isn't an issue, is this still valid? Pros/Cons of fitting them above or below the horn side braces? Sketchup shows them below.

viewtopic.php?p=30429&hilit=DR280+handles#p30429

It also talks of routed handles in the rear of the cab, the thread is ancient and the pictures aren't available anymore. I think I have an idea of what they may look like, are they on the corners of the cab vertically routed into the back and sides?

Am I asking these questions in the right place, or should I start a new thread? I considered a build thread, however It'll take me another year to just dryfit the first cab I reckon

G'day Keryn!
On the same page you linked, a bit further down, Bill says:
Dish handles are OK if they're small. Monster size dishes will block too much pathway.
In my mind, it might not matter so much if the handles are above or below for the first/ first pair cab (I reckon below would make cab handling better myself) but certainly should be below for a second pair stacked, because of handling.

Towards the end of my DR250 build thread (now on page 2 of build threads) you can see what the routed rear handles look like from a couple of angles. Make a jig and they're a piece of.. err... cake....

Good morning all, I'm looking for feedback on this driver as a substitute for the 3012HO, apart from the VAS being low the specs are ok (just!), I'm not educated enough on T/S parameters yet to know how important VAS is, though I do understand all parameters are important, is there wiggle room here? And would the graphed response count as a rising response to midrange, or cone break-up? Xmax is 7.1mm

Vas doesn't matter all that much, so long as it isn't hugely large. The spikes above 2kHz are break up, but don't matter as they're above the crossover frequency. It is shy of the response of the 3012HO from 1kHz-2kHz, due to higher Qes.

More good news! Legend, thanks for the light speed response mate :D

Good evening all,
Looking at this compression driver as a F151M-8 substitute for us in Aus,
https://www.sbaudience.com/index.php/pr ... co-44cd-k/
The 5lb weight and absence of a resonance value is my concern.

Judging by the FRD and ZMA I'd say it's fine, but heavy.

Ok great, thank you Bill.
I could add extra bracing to the CD mount to combat weight..
When you say FRD and ZMA, are you looking at frequency range and maximum impedance?

Good afternoon all,
there's an opportunity here for purchasing a pair of opened but unused 3010MBs, as they're discontinued, l'm wondering about the availability of recone kits?
Also the frame doesn't look like it wants to be back mounted, like in a DR250

There may be kits available but they're sold in quantities of ten. The mounting is normal.

I doubt that you'll be able to get recone kits for those. The current price list doesn't show any, nor did the list from 2022. They produce recone kits when they do a production run of the speakers, so if they don't still build the speaker - there won't be a production run.

6 - T39 3012LF
4 - OT12 2512
1 - T24
1 - SLA Pro
2 - XF210
