What’s your opinion about Dali speakers?

Dali hasn't really impacted the USA market as much as some of the other household brands yet, but I've found them to compete on a cost basis with them. When shopping for surround sound you're likely looking at paradigm, kef, klipsch, polk, revel, b&w and whatever BB has on sale. Dali has a huge lineup worth investigating.

Average speaker

I’ve owned Dali’s before & demo’d most of their line about 5 years ago..I didn’t care for the ones with the hybrid tweeter array.I felt the treble seemed disconnected from the mids & bass..I did like the simple 2 ways with silk tweeters & really like their mid bass/bass drivers.Those wood pulp units with the SMC tech seem to have a wonderful,lucid,tonally saturated sound that is addictive,ESPECIALLY with tubes or Class A SS driving them..
I do however prefer Dynaudio overall to the Dali’s..Dynaudios tweeters are IMO,SECOND TO NONE & their BUILD QUALITY seems superior...

I have the dali megaline 3 towers with ribbon tweeter it is a referance speaker.if you can find one used it's a bargain. They are quite tall but you can use 1 r 2 or three towers.they stack.

Dali probably has the most versatile speaker lineup in the world. Their top end in-wall speakers are killer. That being said I think you are better off looking at KEF. The Center channel is the most important speaker are the Center channel and the sub/s. 60% of the sound comes from the center channel speaker. Due to home theater crossing over at 80hz or higher the Subwoofer has to handle below that frequency For All The Speakers. I am not a KEF fanboy. I have had them in my home and have listened to 99% of them. Kef makes a nice Sun called the KF92. It plays down to 11 hz at -3db and be hooked up wirelessly with an adapter. Due to the QCore tweeter/ midrange, the off axis response is probably best in the industry. What that means is no mater where you sit or stand you get great sound which is what you want in a surround sound system. I would go with the R Series at least for the front three. Go with the R3 bookshelf speaker and matching stands. They bolt together for stability and you have great bass for music without using the subwoofer. Unless you have two rows or more of seating or an additional area like a bar or pool table I would stick to 5.1/2.0. The more speakers you add the less power the speakers typically get in a surround receiver. Some can bi-wire for more power and I would do that. Personally I prefer and use separates to get the best sound. For the back speakers you can use what ever you want. Meaning not KEF. I like the idea of using the R3s again but that is over $2600. Do to surround music it really helps immerse you without too much DSP. That being said the DSP setup will blend whatever speakers and subs you pick. You might want to look online for a sub. They come pretty cheap regardless of brand. Especially since they have come out with v2 or upgraded models. KEF upgrade to Meta tweeters in the past few years. You can get the non Meta versions at a huge discount. Sorry this is so long but I wanted to cover the bases and explain why.
