Ian, re the Punishers for £340.00. I don't know why but while I was putting together an order with Thomann the 12.00's were at £205.00, I went and made a coffee, when I came back the price had dropped to £163.00. Needless to say, I jumped on them. The next day they were back up to £205.00.

I don't know if it was an input error or something, either way they honoured it! I've had nothing but good experiences with Thomann. Great prices and bloody fast delivery.

Due to the fact I've already got the two 12.00SW's I might sell the 12.00SWDCNDW's (brand new, still in box) and buy two more 12.00SW's. If anyone's interested?


I'm interested in the DCNDWs -- PM me with price inc. postage and your location, maybe I can collect them.

Agreed, but that's because you just can't put 1000w into them on anything bass heavy without the drivers cooking. Timebomb from Rebel Bass in Lancaster runs his at about 700w max I think and has had no problems. Pretty sure he has aluminium access panels though.


1000 watts AES, plus once loaded up the amp is probably seeing a lower than assumed resistance bringing power up even more. I bet on sub heavy music people are really ragging them thinking they are well within limits.

The cabs I built for Fred, x8 had no ali panels, 8x had ali panels. I beleave he was running two stacks - powered identically. One side ali panels one side not. He over did it I assume on one occation and lost all the drivers with no ali panels... ali ones survived.

I think Marios still has some Punishers in a venue in Manchester - it might be about hooking them up to a Powersoft amp and seeing what the actual Z value is for the cabinet.

Sounds after just reading up a fair bit on the Puns, that if I had them, i'd go for a metal access panel (possibly with a foook off heat sink on it) haha

put one in the mouth, rather than on the side!

The problem with putting them in the mouth is the brace is in the way, i did double braces so i could put an ali panel in between them, right behind the pole peice vent, its only a small surface area though so i doubt its doing all that much, was going to have a play about with some heatsinks.

The increaseed loading of a cab can only rase impedance not lower it, it would be interesing to measure real impedance but the problem with that is it will change depending on how many you stack, how close to walls you are, if someones stood in front of it etc. so its not all that usefull to have a number that dosent really tally to the real world,  i think the best way to know how much power you can give them is to measure VC temp in real time,  not sure if the powersofts can do that?...  it can be done though..., ill get arround to it one day.

You'd probably be able to get a good estimate using real-time measurement of Re and the known ohmic heating constants for copper.

What's the best materialfor the side panels. Ally? Would welding cooling vanes directly to the plate make a difference? As opposed to bolting on pre fab heatsinks! Asuming that's what you mean, of course!
