I also measured the power consumption of one LT1300 while doing that FOTF clip, and it peaked at only 130 watts consumption. Highest I ever recorded was WOTW with 190 watts. Never had any tripping problems on my 15amp circuit even if both eD's are switched on at the same time.

I have 2 1300s on a single 15 amp circuit (a7-450, a7-350), along with some other stuff....I have NEVER tripped a circuit.

While an amplifier is rate at 1300 watts RMS, that does not mean your source material calls for all of that power constantly. Music/ Movies are dynamic content. They have peak and valleys. This asks for power beyond 1300 watts and times, and much less than 1000 watts at other times. Its not truly calling for 2600 watts RMS in a constant manner.

If you had the two amplifiers hooked up to single 15 amp circuit while playing 0db test tones on a constant 4 ohm load. You would be tripping the breaker. How do I know?

I know many people running 3 or more Behringer EP2500/4000's on a single circuit as well. There really is more to it beyond RMS power.

Not to mention the LT/1300 amplifiers ICE Power design really increases their overall efficiency.

Thanks Alex. I've never tripped my circuit and I've listened at above reference on that single circuit with a total capacity of around 4000 watts for all my equipment connected.

Was just curious how that could be...that makes sense to me now.

I have xpa-3, dual a5350s, onkyo 876, ps3 or xbox 360 (whichever im using at the time), and 73" mitsu plugged in.

Hi all,
I began shopping for a new sub on Saturday after my Klipsch KSW-15 crapped the bed after 11 faithful years. I found this thread while researching replacements and after hours of reading I purchased a new A5-350 today. ED actually had one in stock and will ship it today. How lucky am I? I look forward to posting my impressions after I get it set up.
Is there a break in period?

2 A7s on the same circuit here too. No tripping.

I know I still owe you guys a full review, but I'll share a quick s** my pants moment the other night during "The Town".

There is a scene toward the end of the movie during the final standoff, where a flash bang grenade gets tossed in the building.

Hooooly Bejeezus. Would like to know where measures on the frequency chart. Didn't SPL it, but it completely scared the crap out of the company I had over.

*Raises Hand*

17 A5-350s will do the same thing if you aren't careful and can't reach enough outlets...Bah, I was going to post the video but it was hosted on ICIX and is now gone.

WOW!!! Great Job...That is Awesome!

At what frequency are you crossing over from the Klipsch to the subs?
post #12229 of 15422
Hey Alex if you happen to see this did you guys get your packing material in today? I'm just sort of checking. I have a friend who has their sub done and is just waiting on the shipping. I know you guys were expecting some today and since he is in Iowa anyway it won't be long once it ships so I was just curious if you guys got your packing material today.

I was reading a thread and someone received a A7s-450 DIY as a present. Is that a special request item because I didn't see it in the DIY section on the site. If so, can I request the A5-350 DIY?

It was a typo, it was a A7s-650 kit.

We are only waiting on A2-300 boxes, but they did not arrive as of yet. But FedEx does not arrive for another 45 minutes, so it is still a possibility. Let Ron know that I will give him a call when it ships, be it today, or possibly tomorrow.

Good news, as you mentioned, its next day to Ron's location anyway.

post #12233 of 15422
Thank you Alex and good call on it being Ron. That was the friend I was speaking of. Thank you also for your fielding of calls from him. I had him checking in each week as of late and you guys were always helpful.

They added MY sub to the A7s-650 gallery today, I think it looks rather handsome, it's cherry veneer with rosewood stain

post #12235 of 15422
Glad everyone's happy. Due to the response here and vendor/manufacturer participation here I decided a A5-350 was the way to go.

However the customer service is making me rethink. A week and a half now to even get the required info to buy a sub.

Guess I'll try to callo again tomorrow and see if ED is in the business of "selling" subs or not.
post #12236 of 15422
So after hooking up my dual A7S-450s, I thought I'd move my Cambridge Soundworks PSW1 (1997 sub, 12in driver, 140watts) somewhere else in the house. After all, what can that sub add when I have TWO 1300watt 18in drivers in my theater???

Just for kicks and giggles, I thought I might as well hook it up to see if it could add anything. I placed it directly behind my listening position, calibrated it to 69db because I didn't want to 'muddy' the sound of my A7Ss (calibrated at 75db each), and gave it a go. WOW! I swear these things are the little engines that could. For whatever reason, it really opened up my A7Ss!!! Bass was much more detailed, and VERY tactile. They literally felt like I had hooked up buttshakers (transducers) to my HT seating. It was unbelievable the difference it made.

So I got out the SPL meter and test tone disc to figure out what the heck was going on. My upper bass really opened up because of that PSW1 (compare the yellow and red curves below)! I don't know if it did this because that's where the PSW1 shines, or it canceled out some frequencies that let my A7Ss open up...whatever the reason, there was no way I was taking out the PSW1 from my HT room.

The only problem was that I had a VERY nasty null at 71hz. I could live with it though because it really sounded so much better compared to the A7Ss alone. So, I was happy for a whole day...and then decided to see what my other listening positions sounded like. All were great except one. For some reason, the left most LP seemed to have less effect of the subs compared to the other positions. Did some quick thinking, and decide to hunt for another PSW1 to fill in any gaps. Unbelievably, found 1 locally on craigslist, and I swooped it up.

I placed it right behind the position that I felt was lacking, and viola! That seat now had the visceral feel like the other ones! I plotted my curves again, and also found out that the 4th sub removed my null!!! (blue curve) I absolutely love these PSW1s....

So below is my graphs starting with Duals (A7Ss), then Trips (A7Ss + PSW1), then my final curve, Quads (Duals A7Ss + Dual PSW1s).

My A7S are tuned to 75db each, and my PSW1s are set to 63db each (combined for 69db). My A7S do the majority of the work while the PSW1s complement them and shake the HT seating. I have 1 eq2 for both PSW1s to apply the subsonic filter to them to make sure they don't distort on scenes outside their tuning....



You can check out my Quads and HT gallery here.

This, hands down, is the best my HT room as ever sounded and the best FR curve I've achieved. The bass is effortless and bottomless and completely shakes my seating. Not sure if I got lucky with my room combined with the A7Ss and PSW1s, but it certainly should give you second thoughts about what to do with the subwoofer(s) that are being replaced with the eD's that you bought!

I'm using a pair of CSW subs nearfield also, but in my case they are P-1000s. I had an original PSW-1 though, it was really good for the times. My CSW subs are acting as midbass modules, while the really low stuff is handled by twin Outlaw LFM-1exs. I'm a firm believer in using nearfied subs for midbass, it really adds that kick!

100% agree. Transducers are great, no doubt....but there's something to be said about sound waves doing the shaking as compared to mechanics...

How do you set it up though?

Is there a crossover or do they both play full range (recieve full signal)?

Is the delay or distance set for the further sub?

When you run EQ do you run it with both of them on?

what about then the midbass lesser sub can't keep up at max volumes?

I have the PERFECT set up to put a cheap sub behind me (wasted space) but the logistics are just too complicated

In my setup, they all play full range from the receiver. I'm running an Onkyo 705 with an outlaw 7125 power amp for the speakers.

However, the EQ2 has a subsonic filter that I use to aggressively cut (12db slope?) the frequencies below 25hz. This helps prevent the PSW1s from playing outside their tuning.

Additionally, the PSW1s are calibrated to 63db each as compared to the 75db each for the A7Ss. This helps out with max output and lets the A7Ss carry the weight relative to output and sound quality.

I ran Audyssey before adding any of the PSW1s and did not run Audyssey after connecting them as I was very happy with the results. The delay/distance is what was set originally by Audyssey. I guess I could play around with that, but I'm happy where it is at.
