Transient Response in Series

[Warmon]

Geez, The more research I do, the more I've come to realize that I don't know squat...

Now I come to find out that wiring speakers in series degrades transient response. I assume this is more important in sealed enclosures than ported. Have also read that listener subjectivity plays a part.

I have not yet run across anything that discusses what happens when one wires DVC's with one in parallel and the other in series. Same thing or only half? Please - help a brother out...

On one hand, there isn't very much "transient response" coming from a subwoofer in the first place. On the other hand, it's always good to be as theoretically precise as possible, and then see (and hear) what results we get when doing these things in the real world.

Since drivers are 'really' inductive, they are high-blocking 'filters'. At least PART of the high freq characteristic of any driver is the fact that it is an inductance.
So if we're talking "ideal" then what would be more ideal than to have a separate power "chain" (amp and wires) driving each driver?

So IF you had a 2-channel amp, you have the options of a home run to each driver, putting the drivers in series, or putting them in parallel; you might also have the option of using one channel of the amp or 2 channels in bridge mode. While there are pluses and minuses for each method (pun intended) you migh find it interesting as far as LISTENING TESTS goes to try each method after you do the calculations and determine what the differences are that you can actually hear.

In the ideal world, you can afford any perfect driver, a nice 10kw power amp, #4 silver wire, etc. In the real world, everything is a tradeoff of $$ vs audio.

When we used to build very high end complex discos with multiple LF drivers (i.e. dual 15 and dual 18 bandpass boxes) we had all those options open, including attampting to discern the financial and installation differences between each method. My suggestion, wherever possible, is a home run from each driver to its respective power amp.

Now when you have an amp inside the box (or right next to the box) that is a bit different than having a 150 foot speaker home run wire, and the wire resistance/impedance becomes much more of a factor in the equation.

Have fun with it!

Thankyou barry..this really helps me to make a decision about where I'm going next.
