    Anyone add the new sound bar to a tower yet?

    It's better to add another pair of 6.5" coaxials to the forward cockpit coaming. They'll be warmer and fuller sounding. But if that won't work for you, then the soundbar option is going to be just fine.

    Anyone add the new sound bar to a tower yet?

    The performance of the soundbar will adhere to the same principles that govern all tower speakers in open air. Speaker cone area and pod displacement. A soundbar has good enough output for listening in close proximity, like within an ATV/UTV. But it will not have the ability to project over...

    Finally finished stereo upgrade on my 2015 242 Limited S

    Matt, I have done and listened to countless sub systems using several methods including all those discussed here. Some of this depends on acoustics. Some on personal perception and tolerances (what is your reference for good sound...systems made for movies or music, etc.). And some on the...

    Audio upgrade going great then, not so much. Help!

    You placed a speaker with a painted metal basket on the transom?

    Krypt HLCD speakers--anyone know anything about them?

    Pod displacement is just as crucial to midbass extension as is driver surface area. No doubt the Rev10 is at the top of the totem pole, with the Rev410 being even better. Both are massive. A component of this discussion, per the OP, is looking for smaller options. And still there are going to be...

    Krypt HLCD speakers--anyone know anything about them?

    There's no secret about how an HLCD provides more projection (or 'throw'). The tweeter is simply louder. The HLCD was created in the late 1920s as a means to fill an auditorium with sound in an era when power amplifiers (long before solid state) were limited to a few watts. And typically the...

    Krypt HLCD speakers--anyone know anything about them?

    A Wakeworld search on Ken Land, owner of Bulletlines, will reveal some scary history. The Bulletlines HLCD is a cheap rip-off of the original Bullet HollowPoint HLCD. 6.5" HLCDs are essentially dinosaurs now, and for good reason. Loud? Yes, but only the treble projects. Horribly harsh because...

    Merry Christmas and Santa Made A Delivery....

    Every subwoofer is a tuned resonator of sorts and has certain or unique damping properties. The same can be said for an enclosure, whether small or infinite. The key to optimum performance is to correctly match the subwoofer with the enclosure. So your suspicion is correct. A true IB sub will...

    Finally finished stereo upgrade on my 2015 242 Limited S

    Well, it will depend. A true IB 10" requires about 2.25 cu.ft. displacement to approximate an infinite baffle. So 2.25 cu.ft. to infinite is optimum. If the view (in acoustic terms) of that displacement is relatively UNobstructed then you're good. If the collective view (path) is less than the...

    242 stereo upgrade coming soon!

    Matt, A Wetsounds SYN-DX4 bridged into two channels and driving two (one pair) of Rev10s is 400 watts per speaker with a 14.4V supply. That might be close to 300 watts RMS per speaker with a 12.0 V supply, which is the lowest supply level you should ever run. The truth is, that in terms of...

    Boat Stereo/Battery Upgrades

    Take the Wetsounds Rev410, or any Wetsounds speaker for that matter. You begin with measurements, such as the impedance curves and frequency response curves, both on and off axis. You do the initial math. Then you do the measurements with sophisticated test gear. Then the final tuning, in other...

    242 stereo upgrade coming soon!

    A Wetsounds SD4 or SD6 going into thermal? Now that would be an execution problem, unless you had a rare defect. For anyone in the market for a new top-of-the-line amplifier, I would check in with Odin at Earmark Marine. Odin is an authorized on-line dealer for both Wetsounds and JL Audio, and...

    242 stereo upgrade coming soon!

    If you tell me what an unregulated amplifier delivers with an unrealistic 14.4V supply, I can tell you within reason what it will deliver with a more realistic 12.5V supply. I am a big fan of JL Audio HD amplifiers. They will deliver their full rated power from below an 11 volt supply to over a...

    Boat Stereo/Battery Upgrades

    We have yet to discuss a measuring device that detects speaker distortion....other than by ear. Will a 10-inch midbass driver in a tower speaker handle 400 watts continuous power? Oh heck NO! However, it will handle more transient/peak/music power.

    Boat Stereo/Battery Upgrades

    Of course there are other methods, even if you are unfamiliar with them. A continuous sine wave in no way emulates a transient and complex music signal. Your sine wave test tone at 0 dB or - 5 dB, may or may not reflect the level of your true music source. A measurement without current can be...

    Boat Stereo/Battery Upgrades

    Whether a strictly regulated amplifier, or an unregulated amplifier, if both are of equal topology (whether Class D or other) the amplifier efficiency will be the same, or too similar to be of issue, at both 4-ohm compared to 4-ohm, and 2-ohm compared to 2-ohm loads. I'm a big, big fan of JL...

    Boat Stereo/Battery Upgrades

    A sine wave test tone should never be applied directly to a speaker at or near full power. So the SMD is effective at measuring a clipped signal at every point in the signal path except for the amplifier output as there can be an appreciable difference in the real power level with and without...

    Boat Stereo/Battery Upgrades

    A couple of notes. 4-ohm versus 2-ohm efficiency? Not a tremendous amount of difference. Most unregulated amplifiers will deliver a premium in power at 2-ohms versus 4-ohms and some are even biased for a 2-ohm load. So with an unregulated amplifier a lower load generally offers more power...

    Per another JB thread, here is the link and discount code that Odin posted.
