Thanks! Any recommendations for a good home theatre setup in this range? I have heard thru my random reddit/Google searches - diamond wherfdale 12.3/12.4 or KLH concord/Kendall, q acoustics 3050
I had Wharfdale diamond 10 setup for few years and in my opinion they are very musical but probably not the best for home theater. I had a low end yamaha setup previously and that always sounded better in reproducing sounds like bullets dropping in fight scene or the glass shattering, (so basically high frequencies.)

I really enjoyed listening to music on wharfedale as there treble is not on the face kind but for home theater that is what I prefer. I have moved to Klipsch RP line and I am quiet happy with the HT performance. I still have diamond 10.2 for music.

RP do not have the siblance of my old yamaha so I can still listen to music for much longer but still have the needed crispness in treble for those glass and bullet sound to be life like.

Different tastes for different people, but personally I don't like passive radiators at all. Thought deftech was the built in powered sub company?
The higher end models have powered subs in each speaker. I have a home theater setup with BP9060s and a 9060 center. Sounds amazing.

More of a throwback design with the built in side subwoofer. Very popular setup in the 90s

Definitive customer service has gone down the drain post Covid. Was too much of an hassle to get the amps in the speakers replaced even when still under warranty . Search on their amp issues

With those passive radiators on the sides, they are not ideal for many locations. If you have limited space where an entertainment center or wall would be very close to it, it may negatively affect the sound.
Just something to keep in mind.

I bought a set of definitive technology speakers. 4 of the 8020's after a few years the amps started to fail. I had heard before i bought them they stand behind them, but they really don't. You can't get parts and they are pretty rude if you call. One started failing after 4 years and the rest after that.

I 'm into electronics and took it apart and fixed the ones i could. A key issue is some the transistors has no heat sink, and started to burn out which is probably why it failed. but they are made poorly.

The speakers are about 400 each on sale but they try to charge about 360 for a small amp that's the collective cost of 30 max to produce. They also usually stop carrying parts. Also taking it a part you need to be careful they have limited protection on the back of the board, and high voltage caps. It's pretty much junk.

I just don't think are good designs with built in amps doubly so with a company like this. My learning is It's better to buy a separate sub for longevity. Definite technology isn't a premium company anymore and they don't support anything they are indeed rude. It's alsoa pain to dispose of these they are big and it's a waste. I replaced it with some Klipsch which a lot of people hate but the people in my family found the klipsch sounded better they were cheaper anyway and i've had them for 10 years with no issues. its' fine if you hate klipsch many do, but i'd just get something else. I'm just brining that up because even a mass brand like klipsch sounded better in my room i got their higher end ones the 280f. they were about 300 each. I bought an independant sub. much better IMO.

Good for a home theatre setup? What would be a good center and rear speakers for this?.
Typically you want to match the same drivers that are in the fronts L and R. All your vocals come from center and if it shifts, it won't sound wierd. Get a Def Tech center channel

I think you can get away with another brand of rears since they are mostly special effects

It's an odd color combo with black on the side
Also no matching center channel
The center speaker is $449 on Amazon.

Agreed with this. Anyone with dedicated HT subs will probably crossover the response curve from these passive subs during room correction, anyway.

Out of the box, yes. But they scale and eq really well. At least that was the case with the d9 bookshelves. Once I paired it with a super cube 2000 subwoofer, Martin Logan forte amp, the r2r hifiman ef400 dac and a tube preamp with tone control, it just sings. The imaging is is so amazing. But I have to admit, without the room correction on the forte amp, it sounded a little too 'in your face' and bright for nearfield listening. The forte has integrated anthem room correction (arc) that comes with a collaborated mic to setup. It works surprisingly well. You can get that directly from Martin Logan for $250 right now. Once I tuned everything to my liking, I got a beautiful, holographic and warm sounding system that really blew me away. Personally I liked the def techs better than the Klipsch 500m, Dali spektor 2 and even the svs prime bookshelves for my setup. The imaging and soundstage was just awesome with the d9's. The Dali's were a close second but didn't get me emotional like the d9's did. I got the d9's factory refurbished on accessories4less for $299 a couple months ago. I had posted on Slickdeals. It didn't get much love though. I feel like people don't know what they're missing.

I would suggest going out and listening to what you can in your area so get an idea on what sounds good to you.

Reading reviews and specs isn't a very accurate way of figuring that out IMO.

In market for a pair of floor standing to pair with onkyo 6050. Have been hoping for Klipsch RP8000 ii to go on sale.

How does this one compare with Klipsch?
If you haven't listened to either, keep in mind they have very different sound signatures.

The RP's are much more on the bright side and easier to drive.

These are much more laid back, to the point if they don't have enough power may sound muddy.

Listening to them would be the best way to find out which sound you prefer between the two.

Perhaps Ascend Acoustics Sierra series bookshelves if they're in your price range. Or Ascend's recently updated CMT-340 SE2 series would be great for HT (and music, btw). They're right up in the area of Klipsch when it comes to efficiency /sensitivity, without the Klipsch horn teeter some people look to avoid. The Denon 760H you mentioned earlier should have more than enough power for them.

Tempting. But with a sensitivity at 85 dB these are a bit too hard to drive for me. My 100watt at 8 ohm/200watt at 4ohm class D amp likely wouldn't cut it.. Just something to keep in mind if someone is considering purchasing. To get the most out of these you'd want to have a 150 or 200watt rated Amp at 8 ohms preferably
