Has anybody tried these speakers? (DWG) - Page 2

My 2ct:
most speakers with poly cones can stand water. If they've got silk dome tweeters, some of the high end will be affected when you use them in rain until the water dries out.
About quality, generally plastic/poly coned drivers are ok, but tweeters need to be silk or some kind of metal alloy like titanium to be good. I don't think I heard many good sounding plastic tweeters, neither alu dome tweeters.
Alu-dome tweeters sound just average.. Paper tweeters sound warm, but can't stand water.
Titanium sounds the best (generally speaking).
A good speaker has a matching bass reflex cabinet.
Since most scooter speakers are handling around 40W max, you will want speakers with a cabinet rated 160Hz-20kHz, not lower than 80Hz, or a lot of the sound quality will get lost in lows you won't be able to hear anyway while riding...

If you can get your hands on alu-cast speakers, they'll last longer than steel cast, or steel stamped, as steel and water don't work well together.

I yet have to find a good sounding speaker for the scoot. If you could only integrate a set of studio monitors in a scoot's housing, but that does not seem to be a very easy job.

For the money these seem to work pretty well.

(the guy should really be wearing a helmet!) even for a test.

P.S. I always thought the acid test was how the speakers perform while riding.

What speakers?

You're supposed to be looking at the pair.....OF SPEAKERS

You're most welcome. BTW, he does just as you said, and puts it on a tender at night.

Depending on how many watts the radio is.

Check Amazon for an amplifier called LePai LP-2020A.
It's a very tiny bright sounding amp, peaks at 25Watt, but it's usable range is 2x7W RMS @8Ohms per channel, or ~12-15W @4ohms per channel.
It's not very powerful, but if your speakers are efficient enough, this amp might be just good for the small cruises.
Those small amps are really great if your SPL levels of speakers are above 89dB W m

I suppose those water speakers aren't very efficient.. Perhaps in the seventies or beginning 80's of dB.

They have a Dayton Audio DTA-100a amp, with 2x15W, which is not going to be much louder, but is more expensive.

These amps will not draw more power than your scoot can supply!
In fact, the Lepai LP-2020A uses merely 2W in stand by, and just as long as you have sufficient efficient speakers, they work quite nice!

I have one of them installed in my livingroom, powering 2xBIC America floor speakers (the one with the 4 drivers), and it's more sufficient to watch movies.
Those BIC's are 89dB SPL though, so they're pretty loud by themselves.

The LP-2020A uses less power at max volume, than my Yamaha Surround amplifier, which uses 30W just being on, without music...

You might as well just install a larger capacity battery (like a 9A battery).

If you check he's got a 100 watt system in his scoot, also went to the DWG website to find the db rating for speakers, (no such luck...yet) I just might call them tomorrow for the low-down, but I suspect they may indeed be louder than you might think.

The trick is to find good and efficient speakers.
Some speakers work like crap, and need a poweramp to power them.

I've heard some speakers 82dB SPL, powered by a 100W power amp, while 89dB SPL speakers can be just as loud with just 1/4th of that power.

For every +3dB you need to double the amp's power.
Choosing good speakers, is a first step.
