Here are pictures of my HT. I've had it for about 1.5 years and absoltely love everything about it including my SVS PB12. However, I now have the itch for more bass.

My room size is 14x26x8.5ft rectangle box in my basement.

My thoughts were to replace my PB12 (in the rear of room) with something bigger/better but as a newbie, I'm really kinda clueless on what to do with a $800 budget. (ported or sealed, etc).

Keep in mind my theater is 100% movies and I wouldnt mind having a tall sonasub in the back where the current sub is sitting.

So, here are my questions.

1) at a $800 budget what would you do? I'll prob try and sell my PB12 for 400-450 to put towards my new sub.

2) What recommended components would you suggest?

Side note: I also have an extra run of 10 guage wire up to front left next to fireplace that currently do not use but could (if that would work for a 2nd sub).

thanks in advance

Nicely done!!!!

What is the wall finish?

What is the length of the wall between the door casing and the closet, where your sub is? And the height of the overhang on the left?

How much more bass do you crave?

The wall finish is a suede which we picked because it has zero reflection.

The distance is about 7 feet. Behind that wall is a small storage room where I pt all of my AV and I use a RF remote so everything is hidden. (pic attached)

I think you need 12 LMS-5400 (18"s) and 12 QSC RM5050s. It's the only way you'll be able to even hear 1dB of bass.

Nice setup!

I'd look at doing a TC-2000 or RL-p15 in a large, low tuned (14-15 Hz) enclosure. I'd probably go with a Behringer EP1500 and a Behringer Feedback Destroyer for EQ. Off the top of my head that should come in at around $650 for the components (or less if you can find the amp and eq for less) leaving about $150 for the enclosure which should be doable. If you are considering expanding to 2 subs in the future you could go with an EP2500 amp for some more room for future expansion.

thanks Geoff.....what type of closure should I consider? This is where I am clueless (ported, sealed, sonotub etc)

I'd go with ported. I have 2 RL-p15s in 260 L sonotube enclosures tuned to 14 Hz that I am flat out amazed with. You can build a ported enclosure as a sonotube or as just a box, it really just depends on what you want and what you think looks good.

Here are mine:

From what I've seen the TC-2000 models a bit better, but it can be hard to get as it always seems out of stock. I think that there is a revision coming to that driver which will further extend its xmax. If you can luck out and it's in stock I'd jump on the TC-2000 (I think once shipping factors in it's a little cheaper than the RL-p15). If it comes to a waiting game then you may want to consider the RL-p15. Even though the TC-2000 may be a slightly better driver, the RL-p15 is still outstanding.

I would do an IB in that equipment space.

I dont really have the room for an IB and certainly dont have the expertise (assuming they are more complex than other options.

Do you mean you don't have the attic or crawl space for it?

And it doesn't really require more 'expertise'. It just depends...

Three threads on this, you must be jonesing for a serious bass upgrade.

Look in here:
http://www.avsforum.com/avs-vb/showthread.php?t=845994 , this is Scotts thread.

It is honnestly the best bang for the $$$ I can think of at the moment.

It looks like you got the space for it, two in a stack if you want actually.

I think there are going to be more driver options in the next 30-60 days, via TC Sounds.

Your looking at 3 sheets of 3/4" MDF and one peice of 8" sonotube for the port, glue fasteners, total should be under $100.

Just doo it, and you'll never look back and say I should have a built bigger sub

Yep, the Rl-p 18 is definitely one of the best deals out there right now.

We shouldn't forget the 15" TC-1000 either. If he wants to save a bit of $$$, it wouldn't be a bad option.

Two of those leaves him with $400 for amp/materials. Of course it appears he may just want a single sub, so I'd go with the Rl-p 18 or TC-2000.

2-TC-1000 15" is $400, the RL-p18" is $369+shipping I think

Use a ButtKicker amp to run the RL-p18 D4 at 2 ohms, modd the filter into something more usable ( I could do this if I had one to toy with ) ButtKicker amps are like $270 or less IIRC.

Absolute CARNAGE under $800

Yeah, I should have been more clear. I knew the single Rl-p 18 cost less, I guess I was referring to a dual Rl-p 18 or dual Rl-p 15/TC-2K setup.

What are you talking about? The subsonic filter on the Buttkicker amp is switchable. Both filters are (the high pass and low pass).

The TC-1000 option would perform at least equally too, but most likely better. I think right now it is probably has the most value.

Well there are coupling caps between stages in the BKA, this is the reason for the shallow rolloff ~-3db @ 10hz. If you modded the 25hz HPF to be something around ~10 hz with some boost you could counteract the rolloff and provide the driver some aditional protection below where the port unloads.

Ahhh, gotcha. I am personally OK with the -3dB at 10Hz though. If I was using it for a sealed sub, I'd probably be more interested in modding it though.

from the bottom up: sealed, ported @ 7.75hz, and again with 12db HPF @ 7.5hz Q1.3
