To put it simply ,very few speaker manufactures bother to try and design a transmission line speaker because it is far more expensive , time consuming and technically difficult to get it right , but I am very glad that PMC have and I am sure you are too 🙂
LOL! far more expensive? a few planks of MDF are supposed to raise the cost of a speaker in some considerable manner? most manufacturers don't bother with TLs because it's not worth it. simple port works just fine, if not better. (sorry, I know this is a little bit off topic but couldn't help myself...)
here's measurements of PMC DB1i

note the ATL's output on the graph.
and here's the same set of measurements for Dynaudio Focus 140. (I choose Dynaudio deliberately because I used Focus 110 for a year and never heard any reflex related noise. of course, badly implemented port will sound bad but it's not the fault of the principle but the manufacturer)

and here's another affordable, small monitor. Epos M5i

hint; compare output into mid frequencies from PMC's ATL and then Dyns's and Epos's port. I really can't see how ATL is superior to simple port. and not only me. here's what J. Atkinson wrote on the bottom of PMC's measurements (in case you didn't reach so far): "However, as with other transmission-line designs we have reviewed, it remains unclear to me what sonic benefit is gained by the increase in system complexity".
and now a few words on topic. someone at the top of this thread was seemingly jeering out of Lindsayt's advise in another thread to move houses to a bigger one. well, I think it's brilliant idea. if your living room is some 3m*3m box you can't really do much about it. maybe except buying some decent set of cans.
and I think you harm yourself buying such small houses in the first place. if there's still demand developers will keep building them. I live in Ireland now, which according to the graph from the link about houses' sizes does not differ much from the UK and on the beginning I was shocked how small an average house was. I thought it was really hard for a family to fit in. and I didn't even take hi-fi into account. at that time I wasn't into hi-fi yet so didn't even bother about squeezing in the speakers. right now I'm renting quite a nice apartment which is just big enough for my needs. but if I were to buy anything it would definitely be something with bigger living-room. and definitely with a higher quality finish. those standard cardboard divider walls are simply hilarious. my take on the subject is; you buy a house for a life so it'd be better if it's something you feel comfortable in, isn't it?
