Starting roll-off in bass at 200Hz? Competend? At least there is a lot of room for arguing.

IMO that's a good thing actually! Too many hifi speakers are not designed to sit close to the front wall.
That's a good point!
You see, a argument. Personally i prever, to give speakers room. Another argument
Does it matter though? Home Theater means bass management is included. With that in mind you're just getting cheated out of bass output.
Not everyone buying his first hifi system wants to spend for an AVR with ARC if his speakers cost so little..
Anyway I agree with you, 'cause I use an AVR as well..
Denon's 5.1 AVRs can be bought for 500$ or so. Even cheaper used.
I would even argue that the majority of Average Joes are more likely to own an AVR than a 'Hi-Fi' Amplifier.
Don't do that Average Joe!
Hey...Spend the most of your money for speakers and buy a cheap amp with tone controls. I did that cheap AVR error before..
He said tone controlsDon't do that Average Joe!
Yeah, please let me elaborate:He said tone controls
tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls, tone controls!
Scary eh @sarumbear

May be a good theory. Could be just cheap, boutique (like this or Chane), and never reliably measured. Then people claim they're great and it takes a lot of effort to remove the mystery.

I'm losing track now. How many speakers have been done in my front-mounted slotted ports? I think there's a message here.
Your point being that this competent Wharfedale design suggests other Wharfedale products would be competent. You still have no way of knowing the competency of an untested brand before testing. I find this information quite valuable to help filter out the noise of options in this budget range.For example:

It didn't hurt the Elac DBR-62 too much or the Kali IN-8v2 (does that count as a slot port?).
At least we can see that it at least should be flared.
Also, this HTD is a transmission line, not just a simple port opening. @amirm , if you can get into the speaker (maybe screw off the terminal plate), a look inside the speaker to see the transmission line would be cool.
One of the things we see here is a planar tweeter crossed over at far too low a frequency. With very few exceptions, planar and ribbon tweeters generate a *LOT* of harmonic distortion if crossed over below 4 or 5 kHz.
This speaker has what looks like a HIiVi or Beston type planar tweeter with horn loading. You really can't use those things down to 2,000 Hz like it seems they tried to do here - the driver has OK amplitude response at such frequencies but horrible THD.
Note- For AMT type tweeters- they have more "excursion" and so produce sound down to the ~2,000 range without all this distortion, generally speaking.

Actually, the main issue with the Elac DBR-62 was a port resonance at 600 Hz.

I felt inside and it seems to be an enclosed space which then ports up somewhere deeper than my hand reaches. Just feeling for the air, vast majority of it comes out the center area of the port. The sides don't seem to be doing much. I will see if I can open it and take a better look.

On front ports, it is almost a guarantee to cause some cancellations and disturbances at some frequencies. This can be minor or not. I too am becoming in favor of rear ports. That way all the internal resonances have to hit the back wall before coming at you, further reducing their impact.
I doubt it is a transmission line design. If it was it would have 12dB/octave bass roll-off. This looks more like 24dB/octave, which is a vented box response. The impedance response also points to a vented design.
