Coaxial vs. Bicone marine speaker

8 posts in this topic

Looking for a couple of new speakers for the boat and in the cabelas website it gives two options either a bicone speaker or a coaxial. Whats the difference?

A bicone probably refers to what is usually called a "whizzer" cone speaker. It's like a little inverted cone-shaped attachment usually attached to the periphery of the center dust cover. Check here.

A coaxial would have a second active driver (generally a midrange/tweeter) instead of the paper "whizzer" cone. Check here.

Coaxial will give you better sound.

If you are looking for the best sound available, check out Alpine.

My experience says go wizzer cone unless your getting a higher end coaxial speaker. The problem with coaxials is that they send the full range to all speakers (the same as a wizzer) so they still don't sound all that good yet. I've found that a good aftermarket (Jenson comes to my mind) wizzer can sometimes sound as good or better and it costs less too.

If you look at the higher end coaxials (component) they will come with crossovers, now these will blow the socks off of the other two. But they cost alot more. Plus there may not be any marine ones out there.

Alot of speakers and decks are all about what looks cool not what sound cool. So you always want to test them out in the store if possible.

There is usually a crossover (high pass filter) to the tweeter otherwise the bass would fry it the first time you cranked it up (unless it's a piezo tweeter - they really don't need a high-pass filter, but tend to sound harsh). The filters are generally very simple 1st order (6dB/octave) consisting of a capacitor to block the low frequencies from reaching the tweeter.

I do agree that higher-end coaxials and the component speaker setups generally have more sophisticated 2nd order (12db/octave) or better crossovers.

have you guys put non marine speakers in a boat before? With those poundings of rain we can take up there I'm a bit worried about non marine and I need to replace my speakers and deck soon.

And to answer the question I believe it's about 1 way vs. 2 way vs 3 way speaks. The more the better as it seperates the sounds for better handling of highs/lows/mids.

I have non-marine speakers in my boat for the last few years. However, they are not paper cone, and they are very well protected from the elements as they reside well underneath the dual consoles.

If the speakers will be fairly exposed, I'd stick with the marine speakers.

Mine are coaxials, and are plenty good for the type of listening I do in the boat. Even the "whizzer" cone speakers probably will be fine for listening in the boat unless one is an audio enthusiast, or setting up a party barge.

As for the more the better, perhaps, but it's not a guarantee. Some VERY highly regarded home speakers are only 2-way designs.

In order for more to be better, extra work needs to go into the design to properly integrate more drivers. That's not always the case.

      Gills should be on or real close to beds. Crappies are on beds on some lakes, done spawning on others. Btw, welcome to Fishing Minnesota!

      Frazer Bay is as far as I venture West but that bay can be very good at times. I prefer Lindy Rigs with a 5' leader,#2 or a #4 hook, red or green bead by the hook, and a 3/4 oz. sinker. That time of the summer minnows and leeches work best but do not be afraid to try 1/2 crawler on this rig! Like PSU said, look with your electronics for the fish, then fish for them! 12" to 32" depths. Cliff

      Fished the big lake this morning ,,, Weather didnt start out nice but the fishing more then made up for it ,,, Got my first double and triple in the new rig today ,,, There is a lot of mud covering this side of the lake but finding clear to tea colored water paid off ,,,Natural colored sticks took a majority of hit today and the cohos have grown 5 inches in the last month ,,, I had one 23 inches today

      Hello Muzzy,   Lots of good spots close to Oak Narrows. I will let the experts pipe in, but I've been doing well in 20-30 feet of water in the Frazer / Smarts Bay area. I would trust your sonar and find spots off reefs and follow down to 20-30 feet. Either jig or Lindy has been working for me with a Rainbow minnow

      Finally making it up this weekend to the cabin since January.  Looks like hit and miss weather conditions over the weekend, but I'm hoping to get some decent time in the boat...as long as the father-in-law isn't cracking the whip too hard  . That's good to hear about the success in Frazier, Matt.  Always seems like we are fighting for walleyes, but I'm hoping to change that and try a few new spots this weekend.  Hope everyone has a safe and good fishing holiday weekend.

      We are from Indiana (land of terrible eye fishing). Staying in a cabin in the oak narrows June 3-10.  This is our fourth year fishing the big V, but have always fished the westside.  Never had great walleye fishing yet.  We normally stay father on the westside like around wolf Bay or Norwegian, so we wanted to find a cabin closer to the Eastside.  Figured the narrows would be closer so we can fish spots on the west side that we've already learned and also venture to the east where I've heard the walleye fishing is better for keeper walleyes.  I'm looking for any tips or locations to try.  Maybe someone could help us out.  It would be much appreciated.  Thank you
