New Hi Bass Speakers

[Phoebe Vet]

Interesting concept but the detection system for locations would be complicated.

The idea for which I wished, would only require that the digital signal from the track reach the amplifier, and would require only one subwoofer.  It seems simpler.

The Soundtraxx idea, on the other hand, would not require sound decoders in each engine.

 Even without Surroundtraxx, nothing is stoping you from doing this today. Especially if you just want to filter out the mid and high frequencies and just have the lows come from under the layout, so you can jut have one big sub. All you need is a sound decoder with a low pass filter on the speaker outputs to pass only the lows to your sub. Just connect it to the track power at come comvenient point and give it an address not used by any of your locos. Then just MU it with whatever loco you are running and it will respond along with the decoder in the loco.

Dear Digitrax (or Lens, or Loksound):

Please design an amplifier that attaches to the rails, or to Loconet, into which I can plug many of your sound decoders and program them to the same addresses as the identical decoders in my engines.  Since it is nearly impossible to determine direction of very low frequencies, I can then use a standard powered subwoofer under the layout that would be synchonized with the ones in the running trains.

 

This is already available from SoundTraxx in their SurroundTraxx system.  I think MRC tried something like this a few years ago but theirs was a miserable attempt.

I tried one of the high bass speakers with a diesel Tsunami and was very disappointed with the sound quality and volume.

I also encountered the notorious diesel Tsunami runaway problem and am going to replace it with a QSI decoder.

The Tsunami doesn't support dual speakers as well as the QSI, so I'll also change the speaker arrangement when I change the decoder.

The diesel Tsunami will be used as a sound-only decoder in a dummy loco where the motor control glitch will not matter.

But, getting back to the original question, a high bass speaker by itself is not as good as an oval or round speaker with the proper baffle because the high bass speaker's frequency range is too limited.  Something like having only a woofer and no mid-range or tweeters on your stereo system.

Thanks for the opinion. Sounds like a two speaker system might be an improvement.

Are the new Hi Bass speakers really any different? Or are they just using a larger, deeper enclosure to get a little more bass? How much bass can you get from a one inch dia speaker.
