trying to figure out a cheap sub setup - Page 2

well I'd rather do the HF.. any ideas to the box sizes needed for them sealed? I dont want anything massive. By that I mean it'll b harder to convince my wife if its massive.

With the HF, a typical 16x16x16 cube would be a nice start to have about 0.707 Qtc.

You can play with the dimensions as you wish, box size for sealed is less important than ported, but I would stay around 2.0 to 2.5 cu.ft internal net with 250W.

If it's too big, the HO can fit in way smaller boxes.

So I was looking at partsexpress and realized that the titanic is only 30 bucks more then the RS. Is it worth the 30 bucks? and if it is would I need more then 250 watts to power it. Would the 350 watt amp for 40 bucks more be worth it. So I guess the three options are the RSHF with 250 watts, the titanic with 250 watts, or the titanic with 350 watts. When I say is it worth it keep in mind the SAF. She doesn't even think I should have a sub at all, but I told her if she wasn't going to get me one for Christmas then she would be getting one. Thanks!

Some people bitched about the SQ in the Titanic line because it's an old design with improperly vented polepiece/spider combo I've heard. If you're going to cross it over very low, I'd guess you'll have no problems. On the other hand, I think the HF and HO are both better woofers, less excursion for sure, but better SQ, triple shorting rings and all other improvements.

It depends on what do you want. Very deep bass will be better with the Titanic for sure.

You would not need a bigger amp, but you can use one to get a bit louder if you wish to, whatever woofer you choose.

Yeah but 100 watts probably wouldn't be very significant anyways. Double the power to get 3db so 100 is near 1/3 of that so I'm looking at roughly 1.2 db. I think I'll stick with the original plan for I'm having a hard time with SAF.
