What makes speaker's sound big?

Stay with tekton, add some subs, two at least, avoid filters if you have them, make sure your amp plugged in to the wall, jump into middle and bass highliting cables and tubes if you have them, try to seal other rooms in your house, just close all the doors when listening. 

Clean SPL (in your room),  Clean Bass Extension,  Your eyes.

Everything else is just meaningless fluff.

You can either achieve a desired SPL, at your listening location, over a desired frequency range, in an undistorted fashion or you cannot.


That SPL is a factor of "total" speaker efficiency, amplifier power, speaker power handling, and room acoustics. I used the word "total" as outside bass frequencies, speakers are directional, and while say a bipolar may have lower on axis response, its total energy at a given frequency may be high, and what gets to your listening position is a combination of direct and reflected.  Have a large room, reflections have a longer path, and energy is less. You are also likely seated farther, so again, less power reaches you.

Note I don't mention speaker size? That is an implementation variable contributing to efficiency, no more, no less, though one can argue if wider range, it does effect doppler distortion but that is getting advanced.

Odds are the Double Impact has a bit more base extension and depending and while their 98db efficiency is likely over stated, they would be more efficient than the B&W, so you are going to need to turn them up.  The bass extension, depending on the music could have a big impact on your impression. That could also be a factor of location as well. Did you use exactly the same placement for each?  Other reviews of the tweeter array show the Tekton having good dispersion so their could be more mid-band energy as well, again filling out the sound.  The tuning of the B&W also looks like it is getting less reinforcement from the port, so if the speakers are close to the front wall, the Tekton may give more bass reinforcement w.r.t. the B&W.

Nope! When I had my wharfedale diamond 225’s set up, prior to getting my tannoys, they more than filled the room with sound, imaged like crazy, with plenty of bass. The speakers often performed a disappearing act and sounds seemed to come from well beyond the speakers, as if emanating from beyond the sidewall! I Drove them with my marantz pm14s1 @ 90 watts. They are astonishingly good speakers for the money!! Bought them after reading Herb Reichert and Art Dudley’s review in stereophile. They were right! If i had to, for some reason, put them back into the system, I would not be sad. Now I drive tannoy eatons with my sugden a21se, and to be honest, they do not play louder, but sound a bit more fuller, more oomph or authority. Do they sound better? That is subjective, as It is more likely that they sound different. Mind you the sugden is only 30 watt class A and the tannoys are only 89 db. However, if I was to put the pm14s1 back in to drive the tannoys, they may play a bit louder. I honestly could care less, as I seldom play music at ear shattering levels. Quality, not quantity, at least in my small world.

i find that scale to music comes from the speakers being properly matched to the room so the music can breathe. the music needs to be able to properly open up and become coherent. then the speakers and amps also need to be properly matched. and to add authority and ease to the scale your amps need to have headroom, and your power grid needs plenty of headroom too.

some good mid bass is also helpful; again the speaker driver surface in the mid bass needs to be matched to the volume of the room so it can propagate. the whole room needs to be energized.

sitting in the near field can also bring a larger scale presentation; more enveloping. but to do that typically requires a highly tuned room or the proximity to the drivers will be too harsh.

my sweet spot is in the nearfield in a very large room. and i am immersed in the music.

i did not read every post, so apologies if someone already posted this.

my experience is with owning multiple speakers systems in multiple rooms, and then visiting numerous audio shows. going to audio shows where you visit 20-40 rooms a day; if you listen for this aspect of the music it is easy to connect the dots.

i moved from my previous home, and built my room in my barn, to mostly accomplish this issue. not have the room limit the power or scale of the music. and it does not.

Thanks everybody. My conclusion is also that driver area is very important and a nice big room.
I have been thinking of smaller speakers and a pair of subs. So I will have the freedom to experiment with different placement of speakers and subs.
Have also been thinking about dipoles. Have heard that the bass should be easier to integrated in the room. Less boomy bass
