6.5" Speaker Baffle ?

Would the addition of speaker baffles help the sound lost from behind the 6.5" speakers in the boat? It seems like a lot of sound is lost behind the speaker.

something like this:

Hopefully David @ Earmark will chime in

Thanks!

Yes, front to rear speaker isolation will help tremendously, especially if the speaker is mounted near the edge of a side panel and both front and rear of the speaker are visible. If it's in a storage area or a large cabinet area leave it alone. The issue is that most 6.5" speakers are designed to be used infinite baffle and require much more air space than those baffles contain. Also, those are soft sided baffles which will flex and possibly distort mid bass reproduction.

If you cannot create a wall or cabinet-type separation and give the speakers as much air space as possible Earmark does have hard shell enclosures similar in size to what you posted that could be used as a last resort.

This has been discussed many times regarding a specific boat over on TMC by David and a few others, myself (a car stereo professional of 20+ years) included.

Tim,
A baffle/pod should be rigid. Soft foam won't do for a speaker as large as a 6.5".
A typical 6.5" coaxial is an infinite baffle speaker (expansive door, trunk, gunnel, etc.) and needs at least a cubic foot to infinity enclosure. Less than the minimum will raise the speaker's resonance and raise the midbass cut-off point.
A speaker that is not acoustically isolated front to rear by the appropriate distance will suffer from a loss of midbass due to cancellation and a loss of power handling due to a loss of damping.
The pod will provide the isolation and improve the damping thereby improving the control, limiting any excess excursion that creates midrange distortion and increasing the power handling.
You can also construct an isolation panel for front to rear separation. This gives you the isolation and still maintains the infinite baffle status. A good fit is important but it doesn't have to be airtight in order to be highly effective.
If your speaker is presently isolated front to rear by at least several feet and loading into an expansive area then you do not have a problem to fix. Adding a pod will diminish performance in this case.
If you have a speaker mounted at the very edge of a open coaming pocket, for example, then you do have an issue that deserves attention.

David
