In the words of the opinion above, purists will say that there is better, but frankly it is, I think, a very good box in this price range.
I tested four other chambers at 18 and 15 "and for me it is those with the best performance, and have the most power, still in that price range.
What I like: A round and punchy, balanced weight, an amp with many connectors.
What I like least: The painting is a little shaky, the cover is certainly practical to protect him, but what idea to have disposed of velcro underneath, that always caught in the wheels!
I just had a concern at the membrane that cramée after 3 uses only, and never at full capacity. The dealer found it weird because there was no evidence of overexploitation stuff, obviously a factory defect. Everything has been changed, and since it works nikel.
I think I would do this choice, by the way I try to acquire others.
I have 2 sub 18D for 9 months now, I also have the 15D from the same brand which I was really happy.
I have already try another brand of subs and good even if the purist will say that there is better is already really good material
How long have you use it?
to about 9 months and one of only two to three months because of the second problem
What is the particular feature you like best and least?
rendering bass is not the same as the 15, the integration of wheels directly on the body that moves 42 kg (and yet it is light for 18 subs) more easily.
by comparing against the 15, it is much more fragile, I burnt a membrane and the amp at 2 ven use module (or the small problem of state above) and without specifically keep the sub permanently in the red, it is most likely due to saturation at the mixing desk (these djs playing all the time in the red) but it was never happen to me before with 15. and it also has a much larger heater module (if they are all the same for the 15, 18 and so the only difference being that only 18 uses the full power)
the cover that slips when subs are on wheels is really good for those who just think the used otherwise it is a little c .... t
