Need help finalizing what speaker to get

Hello, t-boba.  Crutchfield is having a sale on the model listed below, I think they are around $329

ELAC Debut 2.0 B6.2

You mention your TT with the Ortofon M2 Blue cartridge and the Schitt Mani 2. All good choices at the price points, but you don’t mention what amp or integrated you have and how much power it has, or whether it is rated well for 4 Ohm speakers or only good for those 6 Ohm to 8 Ohm. That does matter. 

As noted by others, in a large room (you didn’t say how large) small bookshelf speakers without a subwoofer are well, going to sound "small". And forcing them to play louder than designed will cause distortion, clipping, or even some damage to them. 

If you are looking for a "party speaker" you likely won’t go wrong with Klipsch RP-600M (either the old version that you might find "new" for a good price) or the newer MK II version. Those are around $489 at Amazon right now!

I have the Wharfedale Diamond 12.2 (got an open box deal at Crutchfield a few years ago) in my den (10’ x 10’ roughly) serving as main left and right speakers in a 5.1 surround sound system powered by an old Denon AVR.  They do the job, but I rarely turn them up much above 90dB. I have them paired with a cheap Klipsch subwoofer and it really helps significantly to round out the sound so they don’t sound "thin". 

I don’t think they are "bright" at all, but then I’m 67 and my hearing rolls off at 14kHz. 

Note these are rear ported. I think the RP-600M are also rear ported, so that might be a deciding factor depending how close to the wall you want them to be. Closer will enhance bass but too close will make it muddy. 

In my living room (13’ x 25’), I recently bought some front ported Triangle BR-04 (the larger brother to the old BR-03) to use for a while until my larger floor standers can be refurbished. 

These speakers are a step up I think in audio quality, but I wouldn’t consider them "party speakers". I have them pulled well into the room and sit on a couch only about 10’ away from them.

If "loud" is your main concern and not audio quality, think about those Klipsch, price some Zu speakers too, known for their "lively" sound and easy to drive. 

At the end of the day, you might be better served for loud sound by some Polk or Fluance floorstanders that have more radiating surface area. 

Note in my computer room, I have the ELAC Debut 2.0 B6.2. Those are not very good in my opinion. They are large bookshelf speakers but have little bass. They are "good" at a $250 price point which is what I paid for them from Crutchfield "open box". 

Once my floor standing speakers are refurbished, I plan on replacing the ELACs with the Triangles and selling the ELACs at a yard sale. 

Note that many reviewers hated the ELAC B6.2, but liked the smaller B5.2, saying it had better bass.  But even so, they are not the ticket for filling a large space with sound. 

Good luck. 

OP, I've owned the Klipsch RP600M and the Wharfedale Diamond 12.2. If I were you, I'd get the Elac Debut 3 DB63 and not look back. IMO, they're that good. 

The feedback I've seen is that the tweeter caps are kind of harsh sounding, a Mundorf MKP replacement can mellow it out a bit.  The MKP line is ~ $10US or less, so it's affordable experience.  And if that still doesn't work, a low value (0.5 - 1.5 Ohm resistor in series with the tweeter will. 

You probably saw some discussions on xover mod for Wharfedale Linton.  I could tell you, being an owner for 2 years, once improvements done for the digital front and component paring, I no longer describe the treble being edgy, harsh or some sort of that.  It is an articulate, huge soundstage and pin-point imaging sounding speaker.  Changing out the cap with good film cap like Jantzen, Mundorf or others will be good BUT I have concern on placing low value serial resistor.  It will potentially introduce phase shift and alter the cut-off frequency bet. treble and midrange drivers.

Let's say a Mundorf Mcap 12 µF capacitor (C), 250 VDC, is used. The nominal impedance of the Linton is rated at 6 ohms (R) in the high-frequency range. The cutoff frequency (fc) can be estimated as 1 / (2πCR) ≈ 2.2 kHz. Now, if you introduce a 1-ohm series resistor, fc drops to about 1.89 kHz — the speaker won’t sound right. With a 0.5-ohm series resistor, fc becomes roughly 2.04 kHz, which is closer to the designed xover freq. but the resistor value might be too low to have any meaningful effect.  You need to give this holistic consideration for its sonic impact, rather than blindly following what other DIYers are doing.

Be careful when giving your “advice” to a novelist. The AI may also pick it up and spread poorly considered advice.

Thank you @moonwatcher . I was originally thinking of getting tower speakers but I could use the portability of bookshelves more.

Also for the size of the room, it’s our living room and it’s connected to the rest of the first floor with no doors. I’m not sure the exact dimensions but just the main room area itself is probably estimated around 20‘x20’. I’m not looking for party speakers and for moving around a lot. Just want to sit on the couch, maybe pull up an extra chair to sit closer, and just relax and feel the music at a decent volume at a distance where I wouldn’t have to be right next to them, and have my son dance around to it, but he’s 3 so anything will be good for him right now lol. 
 

I originally ruled out the Debut 2.0, but after hearing about the Debut 3.0 dB63, I’ve been inclined to choose those as my speakers. Also because I do plan on adding a subwoofer later when I save up for one, I’m fine if the bass isn’t too present with those. Even more now with @audionoobie ’s comment right after haha.
