2-way speaker with best bass


I know all the arguments about how crossovers can screw up loudspeakers, and hence the many inherent advantages of 2-ways over multi-driver designs. But there comes a point where the laws of physics can only be bent so far...

So... what IYO is the 2-way speaker that most successfully plumbs the depths, that provides the best full, but "tight and tuneful", bass, with good pitch definition, without completely messing up the higher registers?

For the moment, let's not worry about how this achievement might affect impedance and sensitivity.

The line arrays in my system profile are 2-ways and have bass as you described in your original post...
2nd vote for the original Advent. At the original cost of about 130$ (I'll stand for correction on price) it was an absolute bargain.
In my room it was the Proac Response 2.5. They really seemed to pump out the bass. As for tuneful though, that goes to the Revel M-20. Not deep but extremely detailed bass.
Shadorne you didn't mention the transmission line cabinet. Helps to get optimum bass from a small woofer. My Meadowlark Shearwater Hot Rods--a TL design--have great bass for a two-way.
The original poster made no claims that they wanted the best bass regardless of type of system. only that he wanted suggestions for 2 ways that had decent bass.

My recommendation is the zaph audio L18 design. I have built two of them, and both times the bass has amazed me. One of the best sounding two way stand mounts I have heard. A very fun speaker. You can view the design at zaphaudio dot com. On the front page, look for the L18 design.
