Out of interest, I just remembered a cheap(ish) cheat I tried once while experimenting. If you have an integrated amp that cannot be preamp/power amp split, but you have a tape monitor switch, you can do the following when using subs. Obviously if you can split the pre/power, or if you have separates, it's even easier.
1) Beg/borrow/steal or buy a cheap active crossover (e.g. Behringer 2310 - about £90) and set it up as a stereo 2 way crossover.
2) Get some decent phono to XLR leads.
3) Connect the input to the crossover from the tape out connection on the amp.
4) Feed the high output from the crossover to the tape in connection on the amp.
5) Feed the low output from the crossover to the sub (with the sub filter switched off).
6) set the crossover frequency to about 120Hz.
7) Run the system so that you are listening to the tape monitor and then play with the levels and C/O frequency to get the bass - mid/high balance right.
For me, this was actually a precursor for going 3-way and eventually fully active, having gone through bi-wiring and bi-amping as well.
The hard bit is convincing the wife that "Yes we do need a hi-fi rack that looks like it came out of a recording studio"
