@asvjerry It's actually quite convenient to search there and this question has recently come up in the guise of using professional midrange drivers.
Speaker choice without need for deep bass
I am slowly moving away from large full size/full range speakers and migrate to smaller 2 way.
This effect is caused by me adding a great 18" subwoofer to the system, and later playing with the 'main' speakers (and main amplifier) relieved of the 50 Hz and below heavy lifting duties (low pass to sub with own dedicated amp, high pass to main amplifier/main speakers).
So the big full range speakers were replaced with large bookshelf. Everything is fine, except that I have a HUGE (by volume and area) open main listening room. But now the 2 way speaker with one 6" woofer just CANNOT 'move enough air' to listen to high level music without starting to distort.
Therefore the next speaker design I want to try is a still small speaker but with two low/midrange drivers simply to be able to play at 'concert level' without distortion; but still no need for very low bass.
Since still in the trial and error and validation phase of my 'concept', any small 2 (if needed 3) way candiate must also fit the VERY low price (used) criteria ($1,000 or less).
What comes to mind?
Note: I had also inquired about the KEF LS50 for example, but was told they (and similar speakers) would suffer from the 'just not enough square inches' issue required for very large rooms.

One of my audio buddies has the GR Research X-MTM Encore (which he loves). They have larger woofers and plenty of deep bass, but it made me think of the NX-Bravo, which has smaller woofers in an MTM in a transmission line and a waveguide with what I think is an AMT tweeter. My midbass drivers dump into a transmission line, and could possibly be one of the things that gives them such a non-resonant boxless sound. Food for thought anyway... |
Go the DIY route. A tried a true design. Something like the Zaph ZD5 which would impress most anyone. The ZRT is another one but I was able to run it full range. Zaph Audio page will give full instructions. Madisound still sells premade crossovers I believe. Madisound will also have other kits. Troels has plenty of designs as well. All using premium drivers for premium sounding speakers for a budget investment. |
Hi/low pass: in my setup, the receiver 'cuts' the main speakers if at a selected frequency (I use 50 Hz, high pass) and sends the low frequencies (under 50 Hz, low pass) to the sub out (to sub amplifier). With small Epicure 5 currently in the rotation, I actually tried even 80 Hz to further relieve the mains for 'heavy duty', but even at 80 Hz, the single 6" low/mid is getting overwhelmed when pushed. As proof of concept, I plan to rotate in a pair of Aviatrix with 2x 5 1/4 currently in small 2nd system: https://www.parts-express.com/SSP%20Applications/PartsExpress@SuiteCentric/SCA%202019.1/img/300-7134_HR_0.default.jpg?resizeid=104&resizeh=600&resizew=600

@knotscott The NX Bravo crosses over to the tweeter at 950 Hz. That is an AWFUL lot of engergy going to the single tweeter at high listening levels. Speaker size: Sensitivity: 91dB
