Soundstage and explosive dynamics?


I’m looking high and low for speakers with the following attributes:

1. Wide and deep soundstage. Speakers can disappear from the soundstage.
2. Decent imaging.
3. Explosive dynamics with force and surprise.
4. Costs less than $10k.

Agree with Shadorne recommendations and also add PMC. For a couple of under the radar choices, consider the Volti Audio Rival and a couple of the offerings from Duke Lejune of Audiokinesis. They would include Prisma, Zephryn 46, and the newest model Azel. Duke’s speakers sound terrific and he is one of the good guys in audio. You could check out Seaton Sound as well. A word of caution, though. I approached them both 4 years ago and again 3 years ago at Axpona about how inadequate their website was in checking different models specs, etc.. They agreed and I was told both times it would be up to speed soon. Looking at their site today, I can see that it is still incomplete. It would be up to you if you would want to pursue them given that red flag, but they do check the boxes that you want checked. They are also active speakers with DSP. Very dynamic speakers. When looking for speakers with explosive dynamics and ease, there is no replacement for displacement IMO.

Fans can indeed be a problem. However, there are also pro audio amplifiers with variable speed fans that do not come on in domestic situations. I recently bought a 2x250 watt rms Yamaha P2500s for my son for just 300 euro. It has a fan, but we have not yet heard it come on ever. Maybe one day, when he throws a wild party and plays his music so loud that the police will come.
It is a very well made and robust piece of gear, with Neutrik and XLR connectors and optional adjustable high pass filters. The larger 2x350 watt P3500s was recently tested and measured as well as many times more expensive audiophile gear.

It also sounds fine (with nice speakers).

Read here for a summary of the results (in French):

CONCLUSIONS
. La puissance annoncée est largement obtenue (370W Rms sans remontée de distorsion, pour 350W Rms annoncé)
. Bande passante extra-large (ceux qui lui reprochent de manquer d'aigu, faudra m'expliquer...)
. Distorsion infime à bas niveau, très faible jusque la limite de l'écrêtage
. Pas de distorsion de croisement, toute petite remontée de distorsion dans la zone 0.5W - 8W Rms; pas mal vu le faible courant de repos de l'étage de sortie!
. Un ampli que l'on peut utiliser en utilisation domestique comme en sono de qualité
. Quant au prix... "honteusement bas" pour un appareil de ce niveau de perfs (400 euros chez Thomann...), de puissance et de protections.

Je suis content d'avoir acheté cet ampli et son grand frère P5000S pour mon système tri-amplifié, ce P3500S va donc rejoindre mon rack pour driver les médiums CMCD-JBL. Je suis convaincu, attachant une grande importance aux résultats de mesure.

Petite anecdote je n'ai pas entendu le ventilo se déclencher pendant les phases ou je le faisais travailler à puissance max le temps de la FFT..
La résistance de puissance, elle commençait à sentir le chaud!

Que reste-t-il aux "classe A" ésotériques et infiniment plus chers? je ne rentrerai pas dans ce débat...

For about five grand, I built custom Tannoy HPD 315 (12" Dual Concentric drivers, ca 1975), using enclosures that are nearly two inches thick, 150 liter bass-reflex, custom built crossovers with top-drawer components, and had the driver surrounds converted to hard edge.

They sound explosive and dynamic as hell, and I am able to drive them effectively with a 9 Wpc SET 300B amp, or 500 Wpc Class D. I honestly don't think they can be equaled by any commercially made speaker systems at this price.

In my experience, they are effective at producing music on a scale that sounds appropriate to whatever music you wish to play.

Just my two cents, but then my opinion is jaded by my daily enjoyment of great music listening.

Hope you find what works for you, with the budget you have to work with.
