Lsi15 or lsi25

ALPHONSE

Can anyone tell me from exp whether the lsi25 is worth the diff from the lsi15, and is the powerd sub any problem?

Its not.. it has a bigger subwoofer at the bottom. Get the 15s and with the coupe hundred you saved apply to a bigger, better subwoofer. Or you could get an amp with the money sub.

I like the 15's alot more. (even if they were the same cost)

The 25's will be a little easier to drive since you do not have to run that woofer, but you will want a quality amp with either speaker anyway. I found the 25's difficult to set up correctly. I was always messing with the bass - to much for one movie, not enough for this song, etc. Drove me nuts.

You are also limited to essentially a sub amp for the woofer with the 25's. If you have a decent amp I think you can get higher quality bass from the 15's. (although bass quality is one of the 15's weaknesses imo. - still not bad for the price, but not nearly as stellar as the highs).

Anyway - when I made the same choice, I evaluated both in my own home and kept the 15's. The 25's were returned.

Can you give us more info on your room dimensions and listening habits, and what you will be powering these speakers with? Properly executed (room dimensions, applied wattage and amperage, stereo music vs. movie soundtrack) LSi 15s can sound much better than poorly executed LSi 25s.

For 2-channel, go with the 15's and a nice strong amp known for having good bass extension and you won't believe your ears.

I asked the same question when I was buying. I ended up going with 15's and running separate, dual subs. My listening room is basically incredible and I have never regretted it for a single minute.

The way I have my room set up one of the speakers is in the corner of the room, while the other is not. This causes the bass to lean towards the left. The advantage of the LSi25s is that you can adjust the output and crossover points of the subs to compensate for an issue like this. With my setup, the left speaker gain is adjusted lower than the right one allowing the bass to be heard exactally in the center of the seating position, and not to the left. My SVS sub is located next to the right speaker allowing some reflection of the LSi25 woofer, while crossed over at 60hz to balance out the lower end. The sub is also not in a corner, about 4 feet away.To me depending on room placement, the 25s have the advantage over the 15s. I originally had a set of RTi12s, and the bass leaning to the left drove me nuts.

I like the fact that the LSi25s go deeper with their 10" subwoofers (20hz) compared to the 15s 8" subwoofer (22 hz). I too use a seperate subwoofer but like reinforcement at those depths.

Agree with Zsolt.

If you pick LSi15, you rather go with LSi9 and separate sub. My case, LSi15 do not blend well with my PSW1000. The LSi15 produces good bass but not strong enough for me. At low volume, I barely hear the bass from LSi15 while LSi25 I can hear the soft deep bass at low volume.


Below is just the copy and paste of my previous posts. If you did search, you may read them.

Lsi25 is much better than Lsi15 but they are a little bit tricky to set them up. It took me a few hours to have my both front LSi25 speakers and my PSW1000 subwoofer all in-phase. As soon as you have them all in-phase they are much better than LSi15. You will have amazing bass with LSi25. On the other side, LSi15 is very easy to set up, you only adjust phase on your subwoofer and it will take 1 minute you have decent sound, but with LSi15 you only have good bass not amazing bass like LSi25. I do not understand why there are many people prefer LSi15 to LSi25, but with my personal experience LSi25 is way to go. Another thing is LSi25 looks much better than LSi15. The only problem with LSi25 is the power cord kind of messy.

I ran 2 LSi25s and 2 subs ( PSW1000 and PSW505) before and found the bass is incredible when all 4 of them in-phase. Even at very low volume, I could hear the low frequency. As I said before, to have all of them in-phase is not an easy task, I had to ask my wife and my 6 years old nephew switched the phase knobs for hours. I had to move the LSi25s to the left and right..., then move the subs to different location ..., then wife and nephew kept switching the phase knobs. My wife was mad but my nephew loved doing that because I paid him to do the work. At the end, we were all happy. I had all of them in-phase, wife listened to great sound, nephew got some money. LSi25s are great speakers but not everybody knows how to set them up. If only one of them out of phase, you will have crappy sound. Phase is the key for LSi25 owners.

My SVS sub is set about 150 deg out of phase to set good low bass. With it in phase, the low end completely disappears. Both LSi's are in phase. I've yet to figure this out.

The ONLY thing I don't like about the 25's is you have to plug them in. If that isn't a problem or concern then go for the 25's. In my opnion they sound better. They are more open and clear. I perfer them over the 15's.
