Tuning is dramatically affected when adding sealed 6x9 enclosures. Read and understand the following information to get the killer results you are looking for.
The IP-6x9-V-SEALED 6x9 enclosures are designed specifically for 6x9 speakers in Harley speaker lids. These enclosures (sometimes referred to as baffles) allow you to dedicate the lion's share of air volume inside of your bags to your bag woofers instead of the 6x9s while also allowing you to take full advantage of your 6x9s high-power midrange abilities. 6x9s are inherently more powerful and have mechanical advantages over other types of midrange speakers such as 6.5"s due to their much larger cone surface area and more capable motor structures.
