The Z-540 uses an I believe 4" active driver with an 8" passive driver in a dual chamber enclosure at like 25w? The PM 4.1 subwoofer is more powerful then the PM 2.1 subwoofer. The PM 4.1 uses Dual 6.5" active drivers tuned to 50-55hz. 70w RMS with a 160w MBO output and can drive down to 30hz give or take a few hz. The most I ever got out of the subwoofer with placement and gain in my smaller room, is an impressive 106db peak output in the 40-80hz area. It is a bit on the boomy side, but it is a cleaner and more accurate sub then the Z series. If you want a sub to compare, compare it to the Z-560. It's very much so like it. The difference between the two is that the Z-560 has better power handling at ear bleeding volume, were the Promedia 4.1 will drive a bit lower and a little cleaner, also blends better with rest of system. Hope this helped.

The Z-560/Z-680 sub have nothing on the PM 5.1 subwoofer except loudness. The PM 5.1 plays lower, has more control and clarity/tightness, its more accurate, and while not as loud can get quite loud. The Z560/Z680 is an 8" inch driver by the way. I'm not saying it's a bad sub, at least for multimedia anyhow...but in terms of finesse(sp?) its got nothing really...at least thats my opinion.

Here is my opinions: 1.) Yes they are, if setup right...the sound is quite clear, and subwoofer drives low. 2.) Yeah they are, but I would get them from an authorized dealer. 3.) If your planing to use this system with your HT reciever, yes it is a must. However if your computer is any sort of decent, then modern software DVD programs like WinDVD 4 or PowerDVD XP, will decode Dolby Digital/DTS/Pro Logic II materal. They also have the ability to downmix the channels as well as LFE channel, as well as support 24bit/96Khz sample rates.

I wouldn't say the SWS hitters lower, just a tad louder, and at higher volumes. It's a well known fact that the PM 5.1's subwoofer is the lowest hitting subwoofer in Multimedia. The only ones that come close to it are SWS, PM 4.1, Z-560/Z680, Crossfire, and Altec 641's subwoofer. At either rate, think of the SWS as a Z-560 subwoofer except a little cleaner.

This thread is really something special...and thats not a good thing either.

What I would do is just take the offer, then sell the RSW-10 brand new, and then get the RSW-12.

"Next up my must have list is the SVS B4-Plus and SS.Who needs a bass bin when you can get the B4-Plus? Ha and I will power them with Bryston's new 14ST powerhouse.Yes sir" FIRE IN THE HOLE!!!!!

The SVS B4-Plus will almost match that volume wise, and will extend FAR further then that Cerwin Vega. Besides I have yet to hear quality bass from any Cerwin Vega, be it home theater or car Audio. All Cerwin Vega is known for is it's loud thundering bass under Car Competitions, but that doesn't nec. make it good bass. Besides You don't listen to 130db "Bass Bins" or Bass anything in a typical Home Theater room or hell bigger room...it's pointless, and you'll be deaf by the time the day ends. But you all fight over this, i'm happy enough with my little 13" tall SunFire Signature which will embaress many bigger subs, 119db at 30hz is no damn game...that is itself is FAR more then enough for me. LoL this is my fav. quote that I read on a review about the SunFire. ~~~~~~~ "Mucho mass + small size = what the hell is going on here? The innards of this neutron star of subwoofers tell the tale. The driver's magnet measures 7.5 inches in diameter, and weighs over 14 pounds. That's about an order of magnitude heavier than magnets used in a three hundred pound Godzilla speaker system. The voice coil itself measures a whopping three and one-quarter inches in diameter. And get this: it has a maximum excursion of two and one third inches! If subs live in a secret world of size does count then most of them are in deep therapy over the True Subwoofer. Their comparison anxiety will only get worse when they find out the Sunfire Signature comes equipped with a Mama Mia! 2,700 watt amplifier. Anything less powerful would just go limp at the sight of such a massive driver assemblage. But hey, the thermonuclear back-kick produced by this huge driver and its magnet would dim even ConEd's power grid. At full output, about 85 pounds of force (That my friends is a lot of kick your *** power) are trying to claw their way of out of this sub's restrictively small enclosure. Of course, because the Sunfire True Subwoofer is built like the proverbial brick outhouse, escape is not an option. However, when they are pounding away in a full shake-the-foundation tantrum, these enormous forces can get the True Subwoofer's half a hundred pounds doing a mad tarantella across your floor. This thing is the Arnold Schwarzanegger of subs. ...And when the Sunfire True Subwoofer was supposed to be dead silent, it was as quiet as a silk nylon dropping on the floor. But Yikes! When Paul Reido pulled out all the stops of the fifty foot high Lay Family Concert Organ in the stupendous CD "Pomp and Pipes" , our apartment walls nearly did a Jericho, come blow your horn, tumbling down act. Meanwhile, the neighbors' pets plotzed, and our guts rumbled in deep organ syncopation. This was deep bass with a vendetta vengeance. The Sunfire True Subwoofer will gleefully wreak havoc on anything that isn't safely stowed."

Well it's a known fact that the RSW-15 has a very clear hard kick, and belts out some mean volume in the 35hz-80hz range. The RSW-15 does extend down to the 20hz area, but with volume that most HT lovers won't go for, personally the RSW-15 hits cleanly to 25hz with good impact (100-105db) that is personally enough for me in my living room, except im now spoiled by the physic defying, beast that is the SunFire signature.

It's about on par with 5.1's subwoofer, maybe a little better power handling at high volume though.

Hmmm, I could of swore the velo was more expensive then that? My Mistake Ear.

It should, and with a +6db boost. However it depends upon many things, and may end up being quite quiet. I tried to use it as I wanted to use the subwoofer downstairs on my big TV, and well the bass was there, but not very loud. I still can't figure out how I could use it down there, or what to do. I don't know, you'll have to wait for a few more replys as I'm not firm with the subject. Sorry couldn't help more.

But can the Velo 18" take on the beast that is the B4-Plus? Considering the B4-Plus is half the price, although you need something like Krell to back it up, but it would still be cheaper. I've heard the B4-Plus, but I haven't heard the Velo. I'm guessing and from what I read, the Velo will drive down low, and I mean to the lowest of octaves!! However The B4-Plus can drive plenty past 20hz in its own right, and do so with some Bone Crunching SPL's. Any comments Ear?

I'm a monthly Sound & Vision subscriber, I find their mag very useful.

Imp. I believe is the same, don't quote me on that which I believe is 4ohm for sats and 2 ohm (1.8ohm) for subwoofer. The crossover of the 4.1's effectly starts at 100hz and plays through around 140hz. Meaning the sats will play down to 100hz, but the sub plays up to the 130hz-140hz range. This is done to avoid any freq. holes. If you want a raw number for the crossover, then it's a 2-pole 120hz crossover. the Z-560 have an effective crossover in the 150-160hz range, so it's a little higher.

My friend is looking for a decent subwoofer for around $200-300, as we all know...finding a decent subwoofer in this range isn't the easiest. However I did find on that did strike my fancy for the price: Bic America V-1215 Subwoofer: 12" Long-Throw Downfiring Woofer with butyl surround 325w (750w Dynamic Peak) BASH Amplifier 22180Hz freq. response with +/- 3db Dual Venturi ported system 40-180Hz variable crossover Signal-to-noise ratio of 87dB Features: 1.High and low level inputs 2.Automatic signal sensing 3.Dolby Pro Logic & Dolby Digital/DTS inputs 4.LFE Channel Dimensions: 18 1/2"H x 17"W x 14" D @ 60lbs Black Laminate Finish ~~~~~~~ The retail price is $500, but I found a brand new one for $300. What ya all think?

Yeah justin is right, this is a bad move...esp. for surrounds.

I forgot about that, yeah if you can find deals on some used subs, hell go for it.

This is weird of me to do this, but I also recommend the SWS, well I recommend 2x SWS for around $300. The SWS will only do down to 30-35hz really, but will be doing it at 110db SPL and well Home Theater Subs can't do that for under that price (Mind you this is 2x SWS's). It's up to you though, you could build your own sub with a custom driver, but it does take a little time. Gamer Depot had a review on three of em, and said at it's peak hit a bone crunching 119db. I'm inclined to beleve them because I got to witness 16x SWS's at a Audio show, and let me tell you...it made my SunFire Sig. look pitiful SPL wise (Peak anyhow, my Sig. destroy it on low end SPL impact)..but then again your using 16x 8" drivers costing $1500-2000 total. Mind you a lot of home theater subs will beat this, you could look at JBL's powercube series for example...which will again beat it at low end impact. This is only temp. anyhoo. The sony is not what it's cracked up to be.

The klipsch RSW-15 has has good impact down to 25hz, that being over 102db. However the SVS would be a better choice for home theater, it's up to you..both sub's are great.

No it won't hurt it, however if you keep playing under those conditions....it's very possible to blow a driver on the sub.

LoL isn't that the true, when I got my klipsch Promedia 4.1's and more importantly my SunFire Signature. Not only did I get a real taste of low end impact and volume, but I heard lower notes on some songs and DVD's that I never knew was there, it made me feel like going through all my CD's and DVD's again lol.

Yeah I would, because I've never experence any of the tweeters having problems, even with surround at max on higher volumes. Klipsch speakers are one of the few speakers in Multimedia that can accually handle 20khz.

That maybe true, but it largly depends on the position the sub is in, and the size of the room. Sure a 30hz wave is 11 meters long, but that doesn't mean it's fully hitting every area of the room with the same SPL...that is why subwoofer position is so important. Besides one side of your ear maybe hearing 105db while the other ear while hearing the freq., maybe isn't as loud since ears are directional. (For the most part)

The PM 4.1's stock wire is 22ga wire.
