Default Pair of CHR70.3's Just Ordered!

Now to decide what enclosures to put them in. They will be used as desk top near field PC monitors and I'd like to make the cabinets as small as I can get by with to preserve desk space (there is no nearby wall either). Any recommendations are appreciated. If these turn out to be good, I will probably add a sub for a great 2.1 system. I'm hoping that these will sound really good. I've seen some good comments about them here. I'm kind of worried about the soldering of the speaker wires to the terminals, with those plastic pieces nearby.
Thanks,
Clay

These work in a milliSize enclosure — ie 4.7 litre… not much smaller.

Dave,


That 4.7L enclosure is for a bass reflex cabinet or a sealed one? Thanks.

If you think of adding a subwoofer, 8L sealed, or a bit smaller with more stuffing, looks good to me, especially with the built-in elevated mid-bass. Even without a sub I'm sure it'd be fair enough in the bass department. Will they have their back to a wall?

No wall nearby the way the room is currently arranged. I have my PC desk out in the middle of a 12' x 12' room.

Also what gauge of hook up wire should I use for these (between the binding posts & the speaker terminals)? Thanks.

Vented. Here are sealed sims. Looks like 7.4 litre net will give you a Q suitable to XO to something underneath, F3 = just under 90 Hz. Do note that the damping pluff you use inside the box will increase the effective size of the box, so something like 6.3 litres is a good target.

We use 24g solid for internal wiring (and usually for external to). A pair of stands pulled from a length of CAT5 cable.

I will probably build the slim, deep 7.5 liter BR cabinets that are shown on the markaudio website. I am tempted by the Pensil R70.3 design though, I will admit.

With the Pensils you might find the subwoofer superfluous.

If I went with the Pensil cabinets, I would have my raised laptop monitor between me & the speakers, which would mess up the imaging. I am experiencing this same issue in another room. Based on this problem, I believe that the smaller desktop cabinets sitting on each side of my laptop would be the better option. Does anyone put their Pensils on stands to raise them up higher? - that's the only thing that I can think of to solve my issue with their placement.
