Beautiful line arrays! Yeah shame the company went bust +1 Good is that there's another company that has brought these LS6's & LS9's back to life. Check out Angel City Audio.

Hey guys, sort of a newbie question here. Which of your subs (if any) would be best suited for home theater use?? Im looking for four 18in drivers to use in 2 sealed cabinets. Im hoping for a flat response from 8hz on up. Any and all advice is greatly appreciated!

That's the plan.

I have a 20amp line thats gonna be used strictly for the subs. It powered a QSC PL9.0 I had before without a problem so I think I should be ok. I think I have a something like a 35amps for my whole house and some how dont think that it can make it. while powering every thing else. Nice amp you have there...any experience with it? When will the subs be in? Well I actually haven't ordered anything yet. Really, I just decided on what I was gonna go with. If things go as planned I'll start ordering parts in the next couple of weeks.

The plan is to build 4 dual opposed cabinets and stack a pair in each of the rear corners, so that'll help with the amount space it'll take up. Im gonna probably use an FP14000 LG clone amp. If i wire them correctly i'll get a 4ohm load per stack (4 drivers), which would be perfect for the 4400watts (@ 4ohms) per channel the amp puts out.

Thanks for the suggestion. I think I've decided to go with 8 18in SSD's. I had an LMS ultra before and It was awesome. But I I can get 8 FI's vs 2 Ultras for close to the same money. I thought about the SP4 but the guys at Fi recommended the 8 SSD's vs. 4 SP4's.

I have all the other frequecies (above 60hz) covered with the line arrays and the 500watt monoblocks that power them. Yeah those towers look dope and the price is very attractive. Are they laminated or is it a hardwood overlay? Im actually a big dynaudio fanboy. Mind telling us how they sound...or maybe compare them to something else on the market. The only proper line arrays I have heard were some Mac setups and they were really awesome. I bellieve they are laminated. I have had a bunch speakers come through my HT the last few years Rocket 850's, Paradigm 100's, just to name a few). And while they were all great speakers, none of them compare to the LS6's. They sound awesome for HT, but music (at least IMO) is where they really shine. The soundstage is GIGANTIC (especially since getting the monoblocks), the mids and highs are perfectly balanced, and the bass is EFFORTLESS (they extend down to 20hz). It really doesnt matter how high or low the volume is, it doesnt matter if im playing hip hop, R&B, Rock, Blues, or jazz, they play Snoop just as great as they do Clapton. Hope that helps.

I guess off hand I don't see any reason an LLT would suffer significantly in the midbass frequencies up to a typical crossover frequency. Inductance and other factors are a larger determinant of high frequency response. I guess the size might require they be placed in some less than ideal locations for midbass response. For example, look at the response between 50-150hz in these two threads, the response is nearly identical. Same sub, different enclosures. The response through the "midbass" is nearly identical, with the added benefit of extended low frequency response and lower distortion. TC2000 sealed TC2000 "quasi"-LLT I'm not trying to sell you an LLT. I just think it would be a better solution. If that's not your cup of tea and you want to stick sealed with a Fi sub, I think I would still probably stick with the SP4. Out of their line up it's probably the best solution for your goals either way. It still requires huge sealed enclosure volumes, but it'll offer the best low frequency extension and maximum displacement capabilities compared to any of their other drivers. Thanks for the links. I wonder how mid-bass would be affect (if any) by an LLT that was tuned to say 10hz?? I did send an email to Fi today, hopefully they'll get back to me soon. I have family in Vegas and will visting them next month. I'd love to stop by and pick up some drivers while im out there.

I've had 6 ported 15in subs at one point in my room. They had plenty of output but just didnt have the presence my dual 18's do. I'm curious as I've never been in a big HT setup, can you hear it or feel it outside your house? Just curious if it presents any problems with neighbors, or if pretty much just stays inside the house. Sorry for going off topic. Our home is fairly new (well built) and the closest neighbor is about 25ft away, so i really dont have any problems with that. Ive played music/movies before at reference levels and stepped outside to see how "loud" it was. Unless youre within a couple of feet from the house you really dont hear much. Now at our old townhouse that had a common wall, forget it! The cops were over ALL the time.

I thought about going the LLT route, but it seems what they gain in the low frequencies they lack in the mid-bass area. I've seen guys run MBM's when using LLT's. I just don't have the room to have huge LLT's AND some MBM's. It seems most of the guys getting into single digits are running the LMS ultra (actually between 4-8 of them) in a sealed configuration. I guess I'm trying to copy that using a Fi driver.

They are AV123 LS6's. I've had them for a few years now and absolutely love them.

Thanks for the compliments guys

Could you please explain this? Reason I ask is because I've seen quite a few builds with people using using sealed subs and getting flat responses well into single digits. I realize all rooms are different, which is why I'm not opposed to adding more subs to increase output. But I'm thinking 4 Q's (or 2 of the SP4's as you suggested) might be a good start.

I'll be using the SMS-1 for the LPF. The room is not dedicated, so i take what i can get from the wifey. I'd be using 2 subs per cabinet in each of the rear corners. No room for them up front unfortunately.

Im running a Denon 4311ci (XT32) and an SMS-1. I dont have an amp right now but will pick some up as soon as i figure out what driver Im gonna go with.

Thanks fellas! My current subs (Epik Conquests) have plenty of output, but im looking to get solidly into the single digits. Im hoping a 4pk of the 18in Q's can do that for me.

Let the record show there are no exposed 2x4's or exposed ceiling fans in our theater room.

Funny thing is his videos came to mind when i read your post. Just wasnt sure if you were talking about him.

huh??? No fans or exposed 2x4's LOL!

Thanks for the reply. I'll check out the Q driver (cant do IB, no space) and maybe give them a call tomorrow. In the mean time any other suggestions is greatly appreciated.
