Alpair CHP-90 Listening Test

Which way to go with CHP-90. Red or Black line in hornresp

I think the red line either stands for smaller box volume or lower tuned bass reflex tube (longer tube).
Black line is the optimal tuned box.
It's hard to say which one is the best.
I vote for red.

Haven't used my tube amp in months. Plugged it in today.
It sounded different here at home. Didn't think there was such a big difference compared to ClassD.
More nuances in the tweeter.
Perhaps not as firmly in the bass, but the sound swings more. Stamp the beat.
I like the CHP-90.
After I've recorded those 100 hours I'll switch back to Maop10.2. Should be exciting.
try the ACAmini is wonderful .....
 
No, no comparison to MAOP yet.
Have tried changing op amps in my dac.
The CHP-90 responds directly to this. They are sensitive to changes.
High resolution. Extremely sensitive. Perhaps more sensitive than Maop.

Unfortunately, there's no such thing as a single, universal 'more room friendly' response. It depends on the room construction & acoustics, the speaker's position in the room and that of the listener, the material played and (not least) individual preferences. Without knowing these, it's impossible to give a particularly useful answer, other than a variation on what I said before. In this case, the alignment represented by the grey line, being more highly damped, may limit excess gain if positioned near boundaries. The ~130Hz depression only apears to be about 1dB & its effects are likely to be completely swamped by variations in room acoustics & positioning; you'd likely get far more significant variation by moving 1ft in any direction.
 
Perhaps final listning test..
Now after 100 hours of recording, you may have reached the CHP-90's full potential.
The bass is tight and slightly deeper.
The details are really at a high level. The voices are top notch and the soundstage is brilliant.
The membrane's light weight really brings out the transients with ease.
For the price, they really provide value for money.
Gives them 9.5 points out of 10.
Good rating.

Compared to the CHP-90, the 10.2 Maop has more weight in the base region.
CHP-90 has more details to make the cone lighter. 10.2 Maop goes deeper in the base than CHP-90. The paper cone is better at bringing out details. The magnesium cone is more homogeneous and heavier.
The CHP-90 is a fantastic driver. I like it very much.
Considering the price, the CHP-90 wins.
It is the smallest driver I have listened to from Alpair. If you like more weight and deeper bass then the 10.2Maop is the winner.
Both of these drivers have nothing that stands out.
You can listen for several hours straight.
