Good info, thanks for sharing.

Thank you, for the price i think I will give this a shot! Any reason this shouldn't apply to a Transformers LE?! I was looking for this exact topic!

DYI pictures and directions to install for the audio challenged?

Pictures with just some basic instructions would be really helpful here as well!! This is my first Stern Pin, is there anything else at parts-express you suggest I pick up while I am at it? An excuse to spend more is the free shipping with $100 spent

These guys have good powered subwoofers that occasionally go on sale. An example: http://www.parts-express.com/dayton-audio-sub-1000-10-100-watt-powered-subwoofer--300-628

... pictures? How about a video? Thread would benefit from some sound proof.

would really appreciate some pics and basic instructions on how to add the new caps.?

Thanks!

Pictures or are we on our own for the caps?

The cabinet woofer still runs full range. A 6-8mH inductor is really needed to clean up the sound. I usually remove the cap in the backbox and crossover the sub. Then you can put a 20 ohm resistor pack on the back box and crank your volume up to 45-50 and really feel the bass.

Any suggestions on what parts to use for this?

This will do for the inductor

This do for the resistor

Would you mind a link to a diagram for install or take a picture of your setup. I can do everything myself, just am unsure about how to wire the inductor and resister. Do these just get soldiered inline?

I don't have a diagram but it's really easy. The inductor is two wires. Remove the + wire from the speaker and solder either of the inductor wires in its place. Solder the + wire removed to the other inductor wire. Done. You can tie strap the inductor to the metal part on the speaker so it doesn't rattle around. The resistor works the same. It's also two wires non directional. On the backbox left speaker, remove the + wire and solder the resistor in place then attach the + wire to the other end of the resistor.

When done you'll need to frank your volume up to about 45-55 because the backbox will be way lower volume. But this will even it out and you'll have a lot of nice sounding bass from the cabinet and the inductor will remove all the mid muddy sound.

I also remove sterns crossover cap when doing this and run the backbox full range. But an iron man won't have thet at cap - the Ve might. It's not a critical step but it's a simple step where you see the cap on the left speaker well the + goes into the cap then a wire from the cap goes to the speaker +. Just remove the + wire from the cap and move it to the speaker +. Remove or leave the wire from the cap it won't matter at that point. Obviously if you soldered on the resistor then substitute speaker + for the end of the resistor that gets the + wire.

Thank you very much for the detailed information. I have a Transformers LE and I do not believe there is a stern crossover cap.

Are you using 4ohm speakers in the backbox or the stock 8? I believe from my research the Stern amp can handle both 4ohm box speakers and subwoofer.

Really appreciate the help! Did you use the sub woofer above? I also was thinking about adding this amp to drive everything:

In your experience is the Stern AMP more than stable or should I save the stress on the Stern and use the above.

THANKS AGAIN!

If you add an amp, high efficiency speaker is not as important, I put a plate amp into my Ironman with Pinball Pro speakers to see how it would act and it was ridiculous, rattled bulbs out of sockets, my wife yelled for me to turn it down, I could feel air wizzing by the lock down bar. It was rattling the hell out of the machine. In other words, an amp is over kill for very efficient speakers......unless you have less efficient speakers needing the power, in fact AMH has the Lepai amp.

The Lepai amp is cool, from the looks of it though, Input would be an issue as it is low level, and you would need high level inputs. You would need a line output converter, so add this to your set up as well (or build one) http://www.amazon.com/PAC-SNI-35-Variable-Line-Converter/dp/B001EAWS3W/ref=sr_1_2

Of course you can always add the amp later as well

Using an efficient speaker you can avoid the amp. For iron man I leave the stock speakers. I change them for music pins where cymbals are important.
