SAMmed speakers für 1000Pro?

[Pim]

I have vaguely considered a subwoofer,  but Yamaha do not make a matching unit for the 5000. Any thoughts?

I'm using two 18" Triad Inroom Platinum subs and they're very easy to like. Here are my points.

1. Get them in any colour or veneer you want.

2. Seperate amplifiers.

3. Very well built cabinet and driver.

4. The amps are fully adjustable via Ethernet from your listening seat. To me, anyone buying subs nowadays without either an app or Ethernet connection isn't getting their money's worth. Adjusting on the fly whilst listening shouldn't be underestimated.

5. No 180 degree phase switch but a proper fully adjustable delay function. This to me is a must! 
This is how I implemented mine. I put a 20 millisecond delay in the speakers in the Expert. That means that from there on, the subs are practically 'in front'. Then I used a 40Hz tone and started changing the sub's delay until I had the loudest sound. i.e. the subs and speakers were working in phase. I then took the delay time from the subs and deducted it from the delay I had set for the speakers. mine came out at 12.5 milliseconds. I then set the 12.5 millisecond delay in the Expert and the subs back to zero. Now I had perfectly time alligned subs. The end result is that I now have the subs set to a lower volume level then when they weren't properly aligned and I get more punchy bass. 

My best advice for anyone looking into subwoofers:
I would always use two subs. There's this miss information on the net that subs can't be located because the low frequencies are omni directional. That low frequencies are omni directional is true, but it ignores the harmonics. Dutch research showed that a sub in the middle of a circle was easily located to about half a metre due to the harmonics. Those harmonics help with soundstage depth. 

Make sure there's remote control, either via an app or Ethernet.

Most importantly, get some with proper phase or delay adjustment. manufacturers who use 180 degree phase switches are stuck in the 90's and it's time they catch up. The difference between a phase aligned sub and one a bit out of phase is easily heard. If you don't have the option on your sub, you'll never know what you're missing out on.
