Help in hooking up a sub woofer.
Please read this thread for ideas on sub hookup with RCA inputs👇 https://forum.audiogon.com/discussions/sub-wiring-help-high-level-speaker-terminal-to-rca-line-level... |
Hello 2468100, No offense but the PSB Subseries 150 at $499 seems like a bit of a toy compared to similarly priced alternatives. It only outputs bass down to 26 Hz and you want a sub that goes down to at least 20 Hz. I suggest you return it and purchase either one of these SVS subs, the PB-1000 that has a port, extends to 19Hz , has a 10" woofer and is 15"wide x 19" high x 20" deep or the SB-1000 that is sealed, extends to 24 Hz, has a 12" woofer and is 13" wide x13,5" high x 15.5" deep. Both are $499 and have both line level/RCA inputs and speaker level inputs. Here's a link to both subs: ttps://www.svsound.com/pages/subwoofers Either of these subs will provide significantly better bass performance than the PSB 150 and the connections to your PrimaLuna integrated via the speaker terminals are legitimately good methods. I'm assuming you don't want a large sub and both of these would be classified as small to medium sized subs, which should be able to be located in an inconspicuous location or even as an end table in your room. They both have the typical adjustable controls for volume, crossover frequency and phase to allow for a smooth integration of the additional bass power, detail and dynamic impact with your PSB speakers. You haven't mentioned if you use your system for just music or for both music and home theater. If it's just for music, the SB-1000 may be the better choice since it's a sealed design and blend well in its detailed character with your sealed PSB Synchrony 1Bs. If it's for music and ht, the PB-1000 may be a better choice since the bass extends a bit deeper on both music and ht. If you have the room, utilizing two subs usually provides even further significant bass improvements in the areas of bass smoothness, detail levels, power, dynamics and impact. SVS is currently having a small sale of $50 off when two identical subs are purchased, so a pair of either would be $950. Tim |
Thank you both for responding to me.As I mentioned I have a small room and was hoping to fit this toy (ha, yes it is) in and just pick up a bit more bass from the system.I now intend to return this unit and dig a bit deeper in to the hookup I would need for my PrimaLuna unit.One thing that bothers me is; even considering that this sub woofer had the proper connections (for my application) it appears PSB thinks it's OK to run a connection from the amp to the sub and THEN a connection continuing on from the sub to the system speakers. That type of connection would never occur to me. I would want to keep a direct connection to my current speakers and run another direct connection from my amp to the sub. Is that an electrical reasonable method? Again thanks to you guys for taking a moment to respond to me. |
246810: " I would want to keep a direct connection to my current speakers and run another direct connection from my amp to the sub. Is that an electrical reasonable method? Hello 246810, What gillatgh stated is correct, your only choice is to get a sub that can be connected thru the speaker terminals. Your preferred method of connection, quoted above, is exactly the connection method you would use for either SVS sub. Yes, it is an electrically reasonable and safe method of connection. You'd just need to ensure your PrimaLuna and sub are not powered 'ON' when making the connections. Once all connections are made and you turn on your amp and sub, the final steps are to precisely adjust the Volume level, Crossover frequency and Phase setting until the newly added bass output of the sub seamlessly blends with the output of your PSB Synchrony1Bs. Ideally, you would use a CD with test tones playable at your crossover frequency (I believe it will be between 40 and 50 Hz) to properly set the volume and phase settings on your new sub. Do you have a cd player? Tim |
Hello Tim,Thank you very much for that information. Getting that Sub with only RCA jacks actually surprised me. I would have never thought it would come like that.To answer one of your original questions which I failed to do; I use my stereo for music only. I'm not much of a TV guy and certainly not a home theater guy, I own 3 dvd's; The Last Waltz, Roy Orbison Black&White and Dr Strangelove, ha. I have my old "5 Disc" Yamaha CD player, which I kept because it has room for 5 discs for background music during the day. About a year ago I finally made the deep dive in to the digital world and bought a Marantz ND8006. It's a combo CD player and streamer. My first attempt at "streaming". I like the CD player; it's decent enough for me. I also have my faithful old turntable (well it's not that old) but I bought my first record player in 1957 and have had one ever since.My faithful little PSB's still sound pretty good to me and I listen to every thing but opera. I may be able to incorporate a sub into this system at some point, I am just really jammed for space (hence the "toy")Thanks for responding, and actually telling me what the connection should be, I appreciate it. I really wasn't getting that anywhere else. |
@246810 What you need is a speaker level to line level output converter: https://www.crutchfield.com/S-DtVn9IwgHWx/p_543ADP12/Russound-ADP-1-2-Speaker-level-to-Line-level-Ad... It is just a simple voltage divider, contain two resistor in each channel. |
