It is fully dependent on the location of the speaker. If you want to use a Q-Plug in the left front, you should also use it in the right front. However, it is perfectly acceptable (and can be advisable depending on placement) to use a Q-Plug in the center and leave the left/rights as stock. If your rears are close to a wall, use them.

We purchased a large amount of these in order to bring the costs way down so that we can offer them to you for a very reasonable price. With that in mind, my plan was such that for a few extra dollars, you can experiment with them and determine what configuration sounds best to you. They are an inexpensive tweak (especially for audio ;) ) that can make significant improvements in your in-room bass response.

In my home, I enjoy the Sierra-1 with Q-Plug B when I run them full range (no subwoofer).

These won't fit into the CBM-170 port and are not properly "tuned" for the CMT-340 SE.

Thanks!

Yes -- absolutely! Crossover setting in your receiver is independent of the Q-Plugs and should be first priority.

Be sure to choose the number of speakers you want plugs for.

That makes sense :( If the 340's would benefit from a plug designed for them for people like me that have them mounted fairly close to a rear wall, I would LOVE for you to consider designing some :D

Thanks!

Thanks Dave, I've just ordered one for my center that's in a cabinet. Seems like a minor investment if it gives any benefit at all so I'll give it a shot. :)

+1. I'd be curious to know more about how customized these are. You hear about people using socks to plug ports. It doesn't get much less custom than that.

Do the plugs have any effect on power handling or distortion levels in the affected frequency range?

---

Using Q-plug B, power handling levels would be slightly increased (distortion would be reduced) from 34Hz - 70Hz compared to a stock Sierra-1.

Using Q-Plug A, power handling would be increased and distortion reduced below 44Hz compared to a stock Sierra-1.

There are just too many variables that affect this for me to provide a definitive answer to your question. Depending on various room acoustics and speaker placement, when used with a sub -- Q-Plug A (Aperiodic) can be beneficial for both music and movies. Much also depends on how well your subwoofer handles the 60Hz range and the low-pass filter slope. Ideally, you want the high-pass slope of you speaker to precisely match the low-pass slope of your subwoofer. Since both of the Q-Plugs change the natural bass roll-off the speakers, either can be beneficial. In your situation - Q-Plug A can offer a dramatic change while plug B would be more subtle.

Hope this helps!

Pair + Center kit (6 plugs in total, 3 of each) = $43.00, includes domestic shipping

---

You mean "2 of each", right?

I don't know if these will improve the sound of my system, but I think that I'll give them a try.

No, he means "3 of each". 2 mains + 1 center, 2 plugs per speaker(1 "A" & 1 "B" plug each).

Gives you all the flexibility of mix-n-matching!
