Default Tempest help

Hey guys, I recently finished my tempest sub. Its in a 122 litre sealed box getting 300 watts of power. I really do enjoy the sound of the subwoofer, great output, great depth, probably one of, if not the best sounding subs ive ever heard. However sometimes I find it could use a little more.. slam.. a little more punch on drum beats and what not. what im wondering is, to get this, should I go with the 65 litre sealed box, or switch to a vented enclosure. I really dont want to lose and of the Tightness of the sub, I just want to gain a little more punch, if that makes any sense.

Using a smaller sealed box will give you more punch at the expense of extension. I feel adding a vent to your current box would be the best solution.

really ? what would you recomend for a vent ? length/diamiter. Do you think 122 litres is to small for a vented tempest ?

Now that I've seen how big Vas is on the Tempest, yes you would need about double your current box size when venting. I thought it was more like 150 litres for some reason.

the perception of lack of "slam" is the comparative flatness and lack of a bass hump that you're used to hearing in boomier and less flat subs.

My advice is to leave the sub as is and attempt some kind of EQ, either on the sub amp (if so equipped), or via some kind of pre-EQ, if not.

Fact is, the sealed sub is giving you lower group delay and better transisent performance, flatter response... all good things. Don't throw that away because you're looking for some punch.

Use your receiver's loudness control if you're desperate

Best solution, buy a BFD (feedback destroyer), and EQ your room while you're at it.

One thing I wonder about, Is would going with the 65 litre High Q box still sound good for mostly rock music. Keep in mind I use my system for about 95% music. Sub 20hz extension isnt to important (although i wont complain if i have it) also, I do find the 122 litre box to be rather large, so thats another pro I can see to using the 65 litre box. Im just woried about lossing overall volume or SQ, or being to boomy

I suppose I could take the box I have now, and fill it with about 60 litres worth of hardwood, (my dad is a cabinet maker so finding that much scrap wood is no problem) would that not give the same effect as using a 65 litre box ? and if i like the new sound, then jsut go for it and build one ?

I use bricks, but the principle is sound.
