full range single speaker

In many cases, poor or lifeless sound is as much a result of less than optimal amplification to drive a particular speaker design than anything else.

Many modern speakers with good extended low end are also fairly inefficient and/or require lots of current to drive properly. The needed amps can become big, heavy and expensive both to buy and run. Class D amplifier technology negates much of this. Or some may chose to go with speakers that are more efficient and also likely also more (lower power) tube amp friendly.

Some of the speaker systems that use the 4" aluminum Jordan driver in a TL enclosure sound very good. A while back I heard one from Carolina Audio and it is worth checking out, if still available. Limited max SPL, but well north of 80 dB at the listening position (in most rooms) and limited deep bass were the trade-offs for otherwise superior performance.

I use C&C Abbys with a NSM 15EXP sub. Sounds good, blends well in a fair sized room 17 x 35. I get good volume from my 8-10 watt tube amp.
