M&K MPS2520P vs Perlisten R5m or S4b ?

[johnraiders1]

Thinking of changing my M&K MPS2520P(active S150) LCR actives to something in Perlisten range, R5m or S4b, powered by Hypex NC502
MX350 Mk ii sub which is the original push pull design.
No budget for changing sub at the moment
Smallish room 3.5 x 3.5x .2.3 meters

What do I gain or lose from the M&K.


Thanks

Gain: Aesthetics? Smaller size for small room? Treating Upgraditis?

Size is 6 of 1...., Perls could go back against the wall, which would make them appear smaller

These: https://triadspeakers.com/products/home-cinema/inroom/ir-silver-monitor/

They are also available in InWall versions. They have super smooth Scan-Speak drivers.

Speakers can be painted any color you wish, or choose an optional veneer.

Looks like Andrew addressed the most relevant gains, lol!

I have a pair of MPS1510, and just love 'em. I recall auditioning against their bigger brothers at the time (before the original M&K went belly up) and felt they actually threw a more compelling image than the S150, and it wasn't really a hair splitting difference. I think it may have been due to the fact that the 1510 are a simple, small two-way with vertically oriented drivers being able to pull off some semblance of point-source behavior, while their bigger brothers suffered from the lateral driver array. That's just a guess, but the MPS1510's exhibit the proverbial disappearing act in an uncanny way.

The Perlisten speakers have really focused on achieving point-source behavior with very uniform power response, so as long as they are otherwise as inert, neutral, and transparent as your M&K's, I would bet that they would image better than them.

Hoping to hear some S5m later this week to give me an idea on the sound.
The imaging either my MPS2510p or MPS2520p is amazing though, I often put my ear next to the centre speaker to check its not on when listening in stero

Don't get me wrong, the speakers definitely have their stregths and may actually work quite well for your situation. Erin and Amir have detailed reviews of the new 2520 and old s-150 respectively. Consensus was that they do some things very well (wide dynamic range, low distortion, linear on axis), but suffer from distinct lobing patters and off-axis irregularities.

Perlisten speakers don't have those weaknesses, so should be more room-friendly, and may image even better than your M&Ks do.
