Members james on bass Posted December 15, 2007 Members Share Posted December 15, 2007 I've read specs spouting about the "Vintage sound" of a sealed cab over a ported/vented cab. What really is the difference in tone? I would think a sealed cab would not push as much air as a ported cab? Would a ported cab sound brighter? Fuller? Louder?

Members rummy Posted December 15, 2007 Members Share Posted December 15, 2007 Sealed cabs tend to be tighter and faster. Ported cabs are capable of hitting lower, and is boomier/bassier. All relatively and generally speaking. You still have so many other factors that determine "tone." Link to comment Share on other sites More sharing options...

Members bassred Posted December 16, 2007 Members Share Posted December 16, 2007 I used to use a ported 15 with a sealed 2X10 on top, (with a Hartke 3500) now that was tone!!!! The 15 filled the lows nicely, and the sealed 10's would punch you in the back, especially with a good hard comp inline.... never usefull for gigs, but I messed around with it and the rig literally moved me (when cranked) Link to comment Share on other sites More sharing options...
Members thelurker Posted December 16, 2007 Members Share Posted December 16, 2007 Okay, as learned from various speaker-making books, and the EV PA Bible. A sealed cabinet usually means low compliance speakers, those with a stiffer cardboard surround (the outside edge of the cone). They respond quicker because they have less "throw", i.e. front & back motion range. They are likely referred to as "vintage sound" because these types of speakers have been around for decades. These are also the same type of speakers used in open-back guitar cabinets, like old Fender guitar combos & such. Ported cabinets use the box itself to help out the speaker on the low end (does little or nothing for mids and highs). Usually using the Thielle-Small parameters, these cabs (the port is designed to a specific length to help "tune" the cabinet) use the long-throw speakers with foam surrounds, and have (generally) better bass response. The cab helps to even out the low tones, giving better (more equal) sound levels over a wider range than the sealed cabs can do. As stated above, a 15" with a port handling the low end is ideal, leaving the unported 10"s to handle mids and highs (such as they are for bass). This info should be available somewhere on teh interweb, if you'd like more info. Link to comment Share on other sites More sharing options...

Members fretless Posted December 16, 2007 Members Share Posted December 16, 2007 the port helps tune it , the shape , length and size of the port installed determines the tuning , so you can dial in a solid fundamental note by cutting the port tube to length .
