Dripping With Bass

By Money Leaker (Rancho Cordova, CA USA)

Bass is clear, deep, oh, and LOUD! If you really want your HT to sound like an IMAX theater, then I whole-heartedly recommend this sub. It fills in the low end seamlessly. It also takes the burden of reproducing low lows off of your other speakers (which aren’t nearly as capable as the PSW505). This is not a cheap “rumble box”. The first movie I watched with this sub connected is Peter Jackson’s “King Kong”. The raptor/bronto chase through the gully is off the hook! The 30-ton bronto’s gallop will set up a standing wave in your intestinal tract!!! But loud does not mean muddy or rumbly with the 505. I was pushing the sub to about 50% volume and I thought my house’s windows may break. And like I said, that was only at about 50% volume. Besides, you want to be a good neighbor and not max this thing out cuz it can be heard clearly from a good 50 feet away. I find that it performs exceedingly well at about 15% of its capability in my medium/small sided living room. At normal/reasonable volumes, this sub recreates the super lows that truly make the difference between listening pleasure and listening rapture. No HT is truly complete without a sub and this one fits the bill to a tee.

a) I definitely WOULDN’T recommend this product if you live in a dorm/apt/condo/townhouse. This thing has the sonic capability to really anger your neighbors.

b) This sub is one of the few in its price range that actually has an LFE input (Low Frequency Effects) in addition to LL & speaker-level. I you didn’t know, LFE & Line-Level (LL) inputs both use an RCA connector. The difference is that the LFE channel carries only low freqs from source whereas LL carries the entire sound spectrum. The LFE goes straight to your sub’s amp whereas LL first goes through your sub’s built-in crossover and then from there to your sub’s amp. If you plug LL into the LFE input, you’ll be asking the sub reproduce the full sound spectrum. Not what you want, of course. Probably not a big deal whether you use one or the other. The Polk’s built-in crossover is fine, i’m sure, but I’d rather do the crossing-over at the A/V unit level.

c) Apparently, a good powered sub has an ON/OFF/AUTO switch, a 180-degree phase-change switch, a volume control, a cross-over level control (this control is not functional if you are using the LFE), a LL input (or two), an LFE input, and a Left/Right channel speaker-level input and corresponding outputs (for a total of 8 speaker wire connectors).

d) The unit seems very well built with what feels like sturdy wood (or MDF) and is somewhat heavy. Which is a good thing. It feels reassuringly sturdy/massive.

e) Would I buy this sub again? Well, I’ve discovered that many of the wonderful items

Yamaha Subwoofer

that are for sale at Amazon are no longer being produced. IE, they are discontinued by the manufacturer. Do a product search at polk.com and you will no find this sub (you can do a search in the product support section to find its corresponding literature pdf). I just guess that that is the nature of the beast. Great products sooner or later get replaced with even newer & greater products. The older and merely “great” (not “greater”) products still need to get cleared out of the inventory so they wind up at amazon.com or other e-tail sites. So, despite the fact that this sub is no longer in production, no longer supported, and is probably a year or two or three (or more) old… would I still buy it again? HELL YES!
