i recently purchased paradigm studio 40 v4's. I feel i'll need a sub, possibly 2 small ones. My question is this: my amp has only binding post for right and left channels. My pre only has 1 pre-out. Where do I hook up a sub? If I hook it to 1 channel on either side how does that affect the speakers?amp? I may get 2 small subs just because all of my stuuf has to be symmetrical or I freak out a bit.
Parts-Express:Dayton Reference drivers and the 240W plate amp.Allows high and low level input and adjustable crossover,level and phase.The 1K ohm/high level input will not effect the impedance that your amp will see.
My sub sounds much better using the speaker-level connections. the input impedance of the amp for th sub has such high impedance that it will not affect you ramp or full-range speakers at all.
Go with Kal's recommendation. It''s more general and practical than the others. Also, 80 Hz is likely to your best bet for crossover. There's rationale behind that choice, not mysticism. If you require symmetry for psychological reasons, go with two, but a single larger sub may be more satisfactory.
There's rationale behind that choice, not mysticism.
You are right, there is rationale...it's called THX specifications.
If I may quote:
It is the product of much development, and, when used in concert with THX speakers (or others which exhibit the correct roll-off), represents the best overall compromise of minimizing localization, extending dynamic range, and as it turns out, minimizing LFE truncation. When Dolby Digital was coming to the consumer marketplace, THX looked at an inordinate number of modern 5.1 soundtracks and guess what they found in the LFE channel: not much at all in the region of 80 Hz - 120 Hz, making their original choice of 80Hz rather fortuitous. Dolby Digital's LFE channel has a digital brick wall at 120 Hz, not a roll-off, so content creators almost always roll-off their stuff, usually somewhere around 80 Hz. Therefore, chucking the top band of the LFE is no big deal but the argument here is that a standard SSP crossover set much lower than 80Hz or so may actually be costing you bass content.
