Hello,I have 4 outdoor Def Tech AW6500 speakers.I am considering the following set up, please let me know if feasible:Zone 2 line out from my Receiver to OSD SMP500 line in I would like to connect two OSD GLS8 subs to the SMP500 How would I do this? Would the SMP500 see a 4ohm load?Next - line out from SMP500 to OSD XMP300 line in How would I make this connection? How would I connect the 4 Def Tech speakers to the XMP300? Would the XMP300 see a 4ohm load?Would the OSD AMP300 be better for this set up, or does the XMP300 work just fine?What is the difference between these two amplifiers?Which is better?Thank you

Hi Nana:Great setup. The SMP500 would be ideal for driving the 2 GLS8 in-ground subwoofers. You have two choices for connecting the 2 GLS8's. I would recommend using our CL3 12/2 gauge speaker wire for the subs. You could run a single two-conductor to the first speaker and tie the inputs to a second two conductor pair to output to the second pair. The other choice would be to home run both wires from each GLS8 to the SMP500. In both cases, you have a parallel connection creating a 4-ohm load. Ideal for max power from the SMP500. Then you connect an RCA Stereo Cable from the signal level output to the Main RCA Inputs of the XMP300. Note: The XMP300 is a newer Digital design versus the Class AB AMP300. Typically the Class D Digital design features a 93% efficient Power Supply so no need for a heavy-duty power supply like the AMP300. You also have a higher power output from the XMP300 for a lower price as well. The XMP500 is also a Class D design with a similar physical size as the XMP300. You can not go wrong with either the AMP300 or XMP300.You have made good choices, along with your Def Tech speakers.TL/5586

I am currently running a 6 speaker audio system from an old but very good Akai amu06 integrated amplifier. The 3 sets of speakers are controlled through your 4 channel speaker controller. I'm very happy with the clean power and the sound quality but I'm thinking about adding an in-wall subwoofer. If I were to purchase this amplifier would it be advisable to run the Akai pre out line to the amplifier and run all 6 full range outdoor speakers and the subwoofer directly from the new amplifier or alternatively, should I continue to run the 6 outdoor speakers from the Power Amp section of the Akai and use the B speaker channel from the Akai to run into the input of this amplifier and then run only the sub directly from the new amplifier? Thanks

Hi Mike:I would suggest connecting to Speaker B to the SMP500 while leaving your current setup with the Speaker B connecting to the Source A input of the Speaker Selector. The in-wall sub would wire directly to the speaker outputs of the SMP500 using 14 or even 12 gauge wire. You want to make sure the output is variable, so the master volume control from your AKAI affects both the high and low frequencies equally. Sometimes the Preamp level is fixed so you might need to adjust the volume from the SMP500. I would try it both ways.Another thing to consider is are you using Impedance Matching Volume Controls for your protection (either the SSVC4 with internal IMVC or the DSM4/ISS4 with external IMVC). The AKAI should see an 8-ohn load on Speaker A from the Speaker Selector. The Impedance is not as much of a factor if you utilize the Preamp output from the AKAI to RCA signal level inputs. It would help to know more about your overall system. What Speaker Selector are you using, and what Brand and model number of the six speakers (3 pair) and In-Wall sub.Thank you in advance; [email protected]/5606

I purchased the GLS8 sub and the SMP500 amp. What are the optimal settings for the amp to get the most out of the sub?

Hi Spencer:I need to know more about your application in order to answer your question better. What makes up the rest of your system? How many speakers will the subwoofer be working with (Brand and model numbers)? Do you have room for two Subs; the SMP500 will drive two of these subs. What other amplification are you using, what sources are you using? [email protected]/5658

Hi Chris:The SMP500 would be an excellent addition to your BOSE setup. We have a couple of choices for outdoor passive subs that would be a good match for your BOSE 151. Check out our FORZA 10 Passive 10" down-firing Deck/Patio Subwoofer (4 ohms). Or you can add one or two of our GLS8 8" in-ground subwoofer (8-ohm). The SMP500 will handle a 4-ohm load so one of the FORZA10 or one or two of the GLS8. The SMP500 features a Speaker (High) level input and Output so can be connected inline between the BOSE 5 and the Speaker 151. Or you can connect directly to Speaker B. And leave BOSE 151 connected directly to the Speaker A. I am pretty sure you could combine the SMP 500 in line with Speaker A and add a second pair of BOSE151 to Speaker B for even more coverage.

Looking at the OSD SL800D in wall subwoofer. Which amplifier would be better the OSDSMP300 or the OSD SMP500? I have an Pioneer Elite SC-05 A/V Receiver that I would use the subwoofer output into the amps LFE.
Thanks,

Hi Job:
The SMP300 would be ideal for the SL800D. It has a direct LFE input. The SMP500 DSP would be ideal if you were driving two SL800D. You would connect Sub1 and Sub 2 to the Right and Left inputs respectfully on the SMP500DSP (they are both mono anyway). The LFE is selected in the DSP programming. Two subs are much better for providing full room coverage. No dead spots when using two subs.
