Not all chip amps are created equal, and that’s certainly the case with LM3886. When listening to several variants using that device designed by Tom Christiansen driving at least 4 Mark Audio FR and Multi-way designs, brightness would not have been in the lexicon I’d use to describe them, but quality certainly would be.

It may depend on what you feed it with. Poor quality in poor quality out. My amplifier is picky on that point. You notice a difference on the CDs. There are many that sound bad but others that have very good quality.
I'm sure most of us here assume that users have a least a decent source and amplifier, and can discern differences in mastering from CD's, vinyl etc.

Mmm I think so.
My translation program is sometimes wrong.
It was not meant to slap anyone. Most people seem to have a very good idea of what they are doing. Forgive me.

Now I have started moving around the speakers in the room.
They stand on stands about 90 cm high.
Now they are 1 meter out from the front wall. Sounds very effortless and balanced. David Bowie (Let's dance 1983) really sounds like David. The sound image is large and voices are heard clearly. The base is well articulated. Plays at medium volume. About 90 db.
They do most things right.

Now I have played at least 50 hours on Alpair 11MS.
They sound great.
Has probably never had better sound at home despite many good speakers over the years.
They get a 10 out of 10 possible.

FHXL, Pensil (and other TLs), and the Mar-Kens (or other reflex boxes) are differnt compromises where shape, size and cost come into play.
Bass extention follows the order i listed them in above, FHXL dragging the lowest bass out of them. Large and unusual shape. A reflex is the box you choose if you want a smaller box or do not need the bass extention — in the case of helper woofers, a sealed box often works as well).
The miniOnken, which as Scott says only look like Onkens is a design alignment that has proven to provide very articulate, elegant bass, but only as low as it goes, and tends to be a “small" box. The ones-like nature makes for very well controlled resonance in the sidewalls, meaning that only the top, back, bottom and baffle need further bracing. The long high aspect ratio vents provide sufficient resistance that the reosnances Sott talks about in the Onken vents is largely squashed but provides sufficient R to push the box towards aperiodic. The 1st step of which in a typical BR, is to damp the vent to increase its resistance, something i have successfully done, quite spectacular during a diyFEST (in particualr a Visaton B200 in a too small vented box — actually with this driver any vented box is too small).

Thank you very much Dave.
I use Nostamus.
I have tried to get more damp in the box. Negative result.
I have filled the BR with damp. Negative result. Maybe to much.
Bass is tight. Well balanced.
Maybe a onken is the way to try.
I have never heard a onken so i cant say if it is better for my ears. I am realy curious.

Dear LeifB60,
Alpair11MS is a good driver.
I think any type of box will make a good sound.

Dear nandappe!
I am Impressed.
You make very nice boxes.
You have build many speakers.
11MS is good. It give me very good 3D.

Dear LeifB60,
Alpair11MS sounds good on both digital and tube amplifier.
Especially the supple sound of the tube amp is excellent.

Dear nandappe!
I love my tube amplifier. 6550 tubes. I will test my digital amplifier and compare these with Alpair 11MS. I'm glad you wrote that they worked well with both. Your videos on youtube were very good. Music I like to listen to. Do you have an opinion which driver is your favorite among those you've listened to? Alpair 11MS is my choice.

Dear LeifB60,
Of the continue products, I like MAOP10 best.
Add the older products, FOSTEX FE208ES-R is the most fantastic driver.

For me the Alpair 10.3 and the CHN110 stay my favorite. Alpair 7.3 was also great (but i don't know if that is still availeble). The 11MS is slightly behind for me. I never liked the 7MS. I never heared the MAOP versions altough.
