Looking for some input, as I don't know what speakers to invest into. I am currently building a bedroom system and want a high quality sound system while still on budget. I want to continue to use and build on this setup for years as I can't buy the whole setup currently. I am looking at a budget of $500-$700 for two floor standers or bookshelf speakers.
But, I already have two 2010 IQ90 tower speakers from 2010 that are currently not working, the highs/tweeter on both speakers sound muddy and compressed, and it must be a blown crossover or tweeter/speaker itself. The treble sounds muddy and not clear on different receivers. I believe they got played to loudly for too long. I haven't listened to these for years but remember liking them alot, definately a different sound but felt like surround sound with even two speakers and had great soundstage. I kind of want to stick with Kef for this reason..but I have these speakers that either need fixed or upgraded and will cost money regardless, so:
OPTION 1 - Upgrade KEF IQ90 Crossovers and build IQ series. (2010)
There is a crossover upgrade on eBay for these speakers with general great reviews for $385. Apparently it makes the speaker sound a lot better. If i buy these and the problem is the tweeter, I can get the tweeters rebuilt for $150 each at Speakerexhange.com. A total of $685 for upgraded crossovers and rebuilt but different tweeters. I could then get Iq6C for a center and bookshelf IQ surrounds.
OPTION 2 - Q150 and Q series speakers (2020)
Sell KEF Iq90 for dirt cheap and buy Q150 bookshelf speakers. This would cost $350-$600.Get Q250c Center channel. Upgrade to 5.1 or atoms down the road. Atmos is something I could see myself wanting and this would be an open door for it.
I am looking for vocals and soundstage over low end bass as I live in an apartment and will not be running these with a sub (yet). I can't have anything super loud, but I do want a capable speaker if I move and have more space down the road. What would be the better investment and long term upgrade? I am leaning towards rebuilding IQ90 because I have them, but would this be a waste and has technology come that far in 10 years?
I currently have a Denon AVR790 but will be upgrading soon to a Denon AVR-X2700H or Denon AVR-S960 or Yamaha RX-6VA (gonna wait a few months to see if hdmi 2.1 bug gets fixed)
What would you do? What speaker would I most likely want to keep and have for the next 10+ years?
