The fuse is held inside the IEC socket by a removable plastic holder with metal contacts; it is designed to accept a standard 6X32mm fuse, with some allowance for variation in length. My spare fuses measure 31.5mm long x 6mm diameter (nothing unusual...

Hato,Its very simple, and can be done without opening the amps.If you receive the manuals with the amps, you will find that they include clear instructions for voltage selection.If not, do as follows:There is a voltage selector built into the IEC soc...

Romy's comments in blue :"...Interesting, as all my drivers, the AK151 and K15/40 are high impedance (15R-16R, DCR around 12R). I do not see a lot of difference between AK151 and K15/40..."Apart from the color the baskets were painted (silver Hammeri...

Though I have difficulties warming to the idea of the "headphone" arrangement for these horns, I do understand that we are talking about loading the room. Similar thinking lead me to consider setting large horns behind the listener in my own longish ...

Here's my latest hallucination :So I'm sitting there listening and sucking down a beer, when, à propos de rien, it comes to me; more on how to neutralize a suspended floor. After shoring it up with screw jacks (which btw, would make excellent scratch...

Well, yes... I've not been to prison in over two years! Apart from keeping me off the streets at night, the results when listening to one of the 40Hz horns were, dare I say, encouraging, though I do hesitate to say so, as the "evaluation" was carried...

As I've said before, I consider myself a beginner. I'll try to bear that in mind as I write this, but it would be wrong to say that I have not amassed some experience on the subject. That experience would have me believe that most don't invest the ti...

Regardless of where you get them made, I would opt for free-standing horns mounted on wheels, as this allows the most flexibility in integrating them with your as-yet-unknown space (for example, you could build such horns into a wall, mount them in t...

I haven't really thought this through, but if I were doing upper-bass horns again, especially if cut using a numerically controlled router, I might consider making tham oval, which would permit going for a horn with a lower cutoff (larger mouth) whil...

One easy way around any zoning issues with an added on room is to find a house with a large garage, knock down the garage and build the new space on the existing concrete pad. That way you won't have to worry about easements and how close you are to ...

One other nice thing about floor or ceiling-mounting the lower-bass horns is that you wouldn't need such a huge living room; the space would be easier to load (sonically), and you'd have a much easier time finding an appropriate house. Romy wrote :"....

In considering integration of my own mid-bass horns, and how I'd ideally like to do it, I too passed by the underground, up-firing solution, and very much like this approach. I do however have a preference for inverting the concept, resulting in a do...

Absolutely true; I end up breaking and rebuilding the mold (actually an internal plug) for each half of the 40Hz horns I'm currently making. Ironically, the resulting horn ends up looking like a mold.For the 115Hz horn, I managed to coax two complete...
