Very Low Volume from the IWs-10
I purchased a Dayton Audio SA 230 sub amp as my SMP 250 was dead when I first tried to use it and customer service has been appalling since then.
I connected it to a Yamaha RX-V671 as I have done with other speakers (Bose) but I couldn't hear anything until I upped the db on AC by 10db and used bass boost on the amp.
Is there a mismatch here somewhere, do I need to change ohms settings somewhere please? I am not an audio expert but never had this issue previously.
Thanks

HI David:
I am sorry you had issues with our SMP-250, with you being from Canada did you buy it directly from us or through Amazon?
Now regarding your setup using the Dayton Audio (which is almost identical to our SMP-250) you are connecting to the Yamaha RX-V671 with the single output to the LFE input on the Dayton Audio SA-230, is that correct? And if so you have set your front gain knob to to half (12:00 o'clock) and turn you Crossover knob to max all the way clockwise (from Yamaha Manual, page 35)? On our amp you have a single gain control which Dayton Audio list as Bass boost. The only difference they have a additional control knob with a choice of frequencies to select from as part of the bass optimization. Now you go to your Yamaha settings for the sub woofer (page 89 in owner's manual). LFE stands for Low Frequency Effect. You select the distance from the sub to your optimum listening/view area and can change the Phase (which should be set to 0 on your Sub Amp). There is nothing wrong with adding more gain with your bass optimization. Once you have set your controls on the Dayton Sub Amp the sub should be controlled from the Yamaha receiver so volume increases or decreases with the other 5 or 7 channels. Are you getting something out of the Sub woofer, just not enough? Have you built an enclosure or reinforced your wall. Please feel free to contact me and tell me about your customer service experience at tim@osdaudio.com and let me know about your settings.
Good luck

I'm planning on seting up a 7.2 home theater in my home and I want to know if I could use this subwoofer for this system (Onkyo TX-RZ820 --- https://www.onkyousa.com/Products/model.php?m=TX-RZ820&class=Receiver&source=prodClass )?

Hi Ed:
This is a passive in-wall sub woofer. Your Receiver features dual pre amp outputs so you would need to add an external amplifier to connect to one of the outputs. You could actually power 2 of the IWS10 subs with our external amp SMP250. But checkout our PS10 or PS 12 Powered sub woofer which you can connect directly to the pre amp sub output. These feature a built in amplifier. And there is a reason they recommend 2 Subs. It gives you better coverage and an external powered sub allows you to experiment on location versus trying to figure out the best sounding location for your in-wall sub. We offer wireless sub kits in case you have problem running a wire to your sub locations.
Good luck

Hi, I have the Yamaha RX-A770 with a 5.1 speaker system already installed in a pre wired house and I am buying this subwoofer only to be used in the pre wired space in the wall. Will this sub work with the Yamaha RX-A770?

HI Johnny :
The output from your AVR is Pre amp only. You need a dedicated Sub woofer amplifier like our SMP250 That has a crossover built in but since the Yamaha RX A770 will output LFE (Low Frequency Effects) will bypass the controls on the SMP250. There are instructions in the manual for setting the controls of the SMP250 when you have a true LFE input signal.
Good luck

Can I install two of them in my ceiling?

Hi Catlin:
Sure, you will need to build an enclosure to make sure it is reinforced plus that it plays more bass coming from the front of the speaker versus behind. Box could be 16"x 14.5" x 6". I would use the joists as the sides of the box. Then make sure your Sub Amplifier can play a 4-ohm load (two IWS10 in parallel). Check out our new SMP500. And for the sub look at the 12/2 CL3 12 gauge speaker wire.
Good luck

I'd like to install two pro series, in wall speakers. What kind and rated of AMP do you recommend? Do I need two, or can I bridge one that distributes power to both. I'm connecting this to a Denon AVR 2500 7.1 reciever. Also curious if the LFE cable can still be used in this set up? Thank you

Hi Ricky:
Check out the SMP500 a dedicated Subwoofer Digital Power Amplifier rated a4 400 Watts RMS at 4 ohms. The IWS10 is in-wall subwoofer rated 25 to 200 watts. It is an 8-ohm driver. So wiring 2 in parallel off the same amp will draw your most power at 4-ohm. Notice the IWS10 has a rated sensitivity of 86 dB which means they are less efficient. You are better off having plenty of power rather than just enough. It is the newest member of our SMP amplifiers. We are adding an SMP1000, but that would be too much power for this application.
Good luck
