The 63s will run off two modified LEAK Stereo 20s, strapped and high-pass filtered at 150Hz

40 watt mono-blocks, 4 ohm taps for both OPTs, giving a 'strapped OPT tap' of 2 ohms.

To retain the QUAD's impulse response the filters are high quality first order Passive Line Level inputs crossovers inside the amps.

I don't think the LEAKs will be working very hard.

I do not expect that system to clip. That's for the colder months.

And in Summer they will be driven by a nice big rebuilt Perreaux 6000C, again with passive 150Hz 1st High-Pass input filters.

Bass? 4 or 5 distributed DIY subs driven by a total of about 600 watts LP @ 150 Hz 3rd order, and analogue Eq'd - for now - by 2 to 4 1/3rd octave equalisers to get down to 20Hz if possible. ? Two big stereo power amps and two integrated amps.

Again, I don't expect much clipping, even though I do like to listen loud. :-)!

I'm not big into Rock music and not big into Mahler, I'm mostly into HIP classical.

I listen to live acoustical music about once a week, mostly choral with organ, and some chamber and chamber orchestra.

I used to record concerts for later broadcast on FM, and intend to go back to it.

As I'm a pensioner this has all taken time, a bit of money each month.

But we are now close to the first install, with an interim bass array of two boxes and 4 spherical encl. Giving 2 9" and 4 8" bass drivers - all getting down to 35Hz. That will keep us going and get my wife happy.

Yet to finish? two clam-shell P-P sealed subs (boxes are built), then build two TL subs with KEF B139s. I already have a large RB sub with a dedicated locally mfd long-throw 10inch ELF driver.
