Introduction

THE SVS PB12-Plus DSP is a self-powered front-loaded vented subwoofer featuring a proprietary 12" long throw driver and 800 watt amplifier with single knob DSP implemented control over filtering, equalization and compression functions. Weighing in at 125lbs+ and costing slightly under $1400, it's no lightweight, and requires more than a little bit of real estate. From its ungodly output capabilities, true 20Hz extension, and ability to play clean and distortion free, the PB12-Plus DSP has truly earned the right to be called a "subwoofer". It's no wonder this mighty sub was the recipient of the Audioholics coveted 2010 Product of the Year award in the subwoofer category. Highly recommended!

Is this sub Bassaholics certified “large” or ''Extreme"?

A $45 RadioShack SPL meter & test tone disc (from realtraps.com) can give you a good idea of your room response. You will want to use the RS spl-meter compinsation chart for frequencies below 31.5hz. If your willing to take the time its a very decent option without having to learn a program. You can also print up blank dB-vs.-Hz chart to plot your measurements.

Will it be as accurate as say an Omni mic & REW? Not quite but you will be able to see what peaks you need to EQ down. You WILL hear an audible improvement if there is room for improvement!! I did this & feel i got great results!!

I have been doing a lot of reading recently on how to use REW so I feel more comfortable in giving it a go. I just sold my SVS 20-39PCi and ordered a new SVS PB12 plus.

I did end up using the realtraps test cd and discovered a jump of about 10db between 30 and 50Hz on my old sub. I wonder if the new sub I ordered will have the same response? If I have trouble getting REW to work, I know I can always use the realtraps cd. Thanks again,

Thanks timoteo for the info and tips for good bass response. I have had a RS analog spl meter for quite some time now and I have used it to set up my speakers and current sub using the AIX calibration disc that Oppo sent me after I purchased the BDP-93.

Maybe the realtraps disc would be better for the sub test tones than the AIX. I may try that. Thanks again for the help. By the way, how do you compensate for the RS spl meter? For example, if the meter reads 75db when playing a 25Hz tone, do you read that as actually 80db? Do you had to the reading to get the actual db. Thanks.

Thanks for the detailed reviewed of the PB12-plus. I have been talking to Jack Gilvey at SVS and he has recommended this sub for my room size(2700cf) and tastes which are 50/50 HT and music. I currently have the SVS 20-39PCi which I have had since 2002 and I am trying to sell it at this time.

I see that it is no longer in cherry finish but black oak looks great. The PEQ function looks nice but using something like REW may be a little over my head. I may just use a test tone program like NCH and trying plotting the graph myself.
