My subs vs custom subs

I've been wondering lately i've have four Wharfedale Pro Delta 218B dual 18" subs they're nice and sound great but at a guess would four properly designed custom made single 18" reflex subs loaded with RCF L18P400 drivers with enclosures tuned at about 30hz give me higher spl, more of a stomach churning sound?

I'd say the pub's live music room is at a guess no more than 40ft long by about 20ft wide, lol. I am right in thinking that powerful subs ideally need room to breathe, and in a room too small the sound reflections from walls can cause nodes right?

Draw a little sketch and post it up with distances between speakers and walls marked in or post some pictures. Rooms do play havoc with low frequencies, guaranteed you have some room nodes going on... places where output sums and is really loud and other places where it cancels. That can't be totally fixed, often the best you can hope for is good output centered on the dancefloor instead of in the loo. Getting the best out of a system in any given room involves finding the best compromise position for the boxes, sometimes that could be all stacked in 1 place other times it might be split up either side of the stage or elsewhere in the room, and sometimes you have no choice because of space limitations.

But have you ever heard the Delta series? I remember the Pro Sound Web guys saying they were the best budget subs you could buy, Wharfedale added the 'Pro' bit to seperate their hi-fi speakers from pro audio/live sound because they also do a Delta series hi-fi range or used to as far as i'm aware. My Delta 218b dual 18" subs sounded just as good as EV's Tour-X TX2181 dual 18" subs when I demo'd them, in fact my Delta go lower down into the frequency range. Reviews before I bought them also stated they sounded better than Peavey's SP series dual 18" subs as well when people demo'd them next to each other. I remember reading online that some sound hire companies use the Delta 18b and Delta 218b subs and take the badges off so people don't know what they are and can only go by how they sound.
