Diy subwoofer advice

[oll]

The driver is from the 13-Ultra Series? SVS sells amp upgrade for the ultra 13.5 driver. Thats what i was going to use. Its $399. Not cheap but if i Build the cabinet it might be worth it.

Got me, that was closest with 13.5" driver I saw.....not that familiar with their lineup tho. I see only an Ultra 16 now at least....

Using an SVS specific amp with eq baked in for $399 is likely cheaper than you can do on your own unless you have an amp and/or eq device sitting around already....someone earlier mentioned a Crown amp (XLS probably), but those don't have eq for a sealed sub built in, so you'd need eq on top of it (altho there are Crown amps with sufficient eq, but they are a different series and tend to cost quite a bit more than XLS....I use XLS with external eq myself on my diy subs).

Got it. The amp they sell is an upgrade because it has DSP. You can use your phone with bluetooth for all the settings.

I'd just email SVS and see if they'll give you the specs so you don't have to guess at cabinet size.

If you measured the old cabinet and know the specs so you can build a new one, then do it. Especially if you can get a pre-made cabinet if building one is outside your skill set.

Don't just wing it, you need to be precise.

Thanks

What are you going to build the box with material wise?

The box would be built with 3/4 mdf. The front would be double in thickness. It has to be braced really well. The driver weighs 65 lbs.

I was just looking at a video review (Erin's?) of an SVS the other day and it had a specific magnet support! 65 lbs is quite beefy! Good luck! Pics when you have 'em.....

ps now that I think about that think it was a Monolith, not an SVS....

pps nope, PB-2000 it was

Thanks, I will post pics if i decide to do this. Thanks everyone for you input.

Sounds like you've got a solid plan, but I'd make sure you can't use an off the shelf plate amp or external amp just in case. That could potentially save you some money, but you're still going to have to talk to SVS.

We're looking forward to see what you do.

Good idea on the amp. I have one from Parts express I could try first. Thanks!

What do you have?

If that driver can be used sealed and ported, then build the ported version. The sealed version will need Eq below the F3 alignment and that information will be custom unless SVS give you the T/S parameters. The sealed amp will have built in Eq, otherwise there would be no deep base. A ported sub does not need, nor can it be equalized, so you can use any plate amp, or an external amp.

People think sealed designs are simpler, but in fact they are more complicated.

You can build a test box and measure the T/S parameters. Parts Express sell the Dayton woofer tester, that connects to a computer. It is easy to use.

After you have the T/S parameters, then you can model your design and compute the porting requirements. A ported design is larger but will give better performance than sealed.

As others have stated, SVS make good drivers, so a good DIY design would be a good project and give excellent results.
