Your A2+/A5+ have a variable RCA output located on the rear panel of the left speaker. Â This connection can be used to connect an S8 Powered Subwoofer (or any self-powered subwoofer) for extended bass response.
You can also add a W3 Wireless Adapter to make this connection wireless as shown below.
More and more often TVs are using fixed outputs, making it tough to adjust the volume without hopping off the couch. Speakers like the A5+ and the HD6 feature a remote control, so you should be able to adjust the volume from their respective remotes. Speakers such as the HD3, A2+s, and original A5s can't be controlled with a remote, so one option we know of to add a remote to them is to put a preamplifier or AV receiver between your TV and speaker; that would give you a variable preamp out to connect your speakers to.
Speaker placement can also play a big role in what sound you get. Â If you feel like it sounds "boomy," one thing we'd recommend is to try and keep as much room as possible between the back of the speakers and any walls as you can. When setting up your speakers in a tight space, one thing that may be worth trying if possible would be toeing the speakers in or out a bit; this makes the port uneven with the surface of the wall behind it and can help reduce reflections (which cause that "boomy" sound).
Yes! We've been notified that the Android App ZappIR supports the A5+s, so if you have a phone with an IR blaster like the HTC One or the Samsung Galaxy S4 you can use the App to raise or lower the volume of your A5+s or HD6s with your phone!
Both the A5+ and the HD6 are not officially supported by any universal remotes. It is possible to use a third party remote, but that remote needs to support IR learning. Â This is a feature that allows a universal remote to learn commands directly from the remote we supply. The Logitech Harmony remote, for example, is supported by the A5+s/HD6s.
You are able to use banana plugs with our speakers just fine! Speakers like our A5+s and A2+s use full size 5-way binding post, and are compatible with standard single and dual banana plugs. Â Most standard banana plugs should be around 4mm in diameter.With the smaller posts, like on the original A2s and A5s, we typically suggest going with pin terminals or spade lugs. Â The spade lugs will need to have a minimum inside opening of 6mm. You can use mini-banana plugs but they are pretty hard to find these days. Â The maximum outside diameter you can have on these plugs is 3.05mm, with a spacing of 3/4" from center to center. Keep in mind that the HD6 and HD3 come with speaker wire that already features banana plugs.
You wouldn't be able to use a pair of headphones directly with speakers like our A2+, A5+, and HD6; in order to use headphones with them, you would need to include something with a dedicated headphone amp, such as our D1. Â All you would need to do is plug the D1 into your computer (either with an optical or USB cable) and connect the D1 from its RCA outputs into either of the inputs of your speakers. Our HD3 speakers, however, do include a headphone output on the front of the powered speaker, so you can plug your headphones directly into them.
It's perfectly fine to swap the left and right speakers if having them that way works better for you. Â It wouldn't affect the sound quality; it would only affect the stereo image (the left channel being on the right and vice versa), which you can easily fix by using an RCA cable and switch the left and right plugs.
If you're using speakers like the A2+s or the HD3 via USB or the HD6s via optical, there wouldn't be a way to swap the left and right channels in your operating system's sound settings or through your software
It shouldn't be a problem having your speakers laying sideways. Â If you do use them this way, we typically suggest using a protective padding similar to the bottom padding on the speakers on the side to help dampen vibrations and protect the surfaces.
