 Experience - from ported to sealed on the MTX 8512

Wanted to check if any of you guys have experience of moving from a vented to a sealed enclosure for the MTX 8512? How does it sound? If I were to increase the gain once I go sealed will it get as loud as the vented enclosure with better SQ? Thanks...

As a general rule, ported box is much more efficient than sealed. The tradeoff is sealed will be more linear, higher power handling, space requirements, and low frequency extension. As you make a sealed system tighter you can also achieve a ripple (db gain) at the expense of linear response and low end extension.

This isn't to say you can't get great results from either, but much will depend on the driver, the box, and the accoustics of the car.

also a sealed box doesn't require as much trunk space as a ported box. Plus when using a sealed box, you won't have to fiddle around too much with the subsonic filter setting on your amp.

Thanks guys...wanted to check if any of you have experience using MTX sub's in a sealed enclosure? I found two calculation on the net; the one below shows the 8512 is good for ported enclosures but the other one I found did not divide the FS/QES by 0.352 due to which it shows better in sealed enclosures. Got a little confused...any help?anyone? From the net - "The first thing to look at is the Efficiency Bandwidth Product for this driver. The EBP can aid you in selecting the proper enclosure for any speaker. To get this, we use the following equation: EBP = Fs / Qes = 43 / 0.352 = 122 An EBP of 122 is indicative of a speaker best used in a ported enclosure. If the EBP had been lower, say between 50 and 90, you would get decent performance in a variety of enclosures - a "Jack-of-all-Trades" driver. EBP below 50 are generally best for sealed boxes. Don't misunderstand, you can put any driver into any enclosure, but you might be disappointed with the results. EBP is simply a guide, however, and good performance has been attained with drivers seemingly unsuited to a particular application."

The gain is not a volume knob,it is to match HU voltage so don't turn it up to get louder.setting the gains wrong is bad for the amp and the sub. If you want to make it louder get a bigger amp and give it more clean power.
