Editor's Notes & Price Research

Written by

This Monolith subwoofer amplifier has an extraordinarily high power output of 500 watts RMS (900 watts peak), which can deliver massive amounts of power when needed. Each Class D amplifier is built around a Texas Instruments 48-bit data path (with 28-bit filter coefficients) DSP engine, allowing virtually unlimited design flexibility with the assurance of no signal degradation.

So tempted, but I am worried that I'll be disappointed with sealed subs for my dedicated theater room. Returning these if I don't like them won't exactly be easy since I don't believe Monoprice pays for return shipping and the 12" are like 70lbs each shipping weight.

I'm in the same boat, very tempted. Currently have dual PB-2000s, and not sure the sealed 15s would be a massive step up for HT.

Yeah, I did a bit of research and decided to hold out for a sale on the ported. My PB12-NSD will be fine until then.

I'm actually looking at the THX-365C center channel speaker, but the same concern regarding returning the speaker if it didn't work out.

I'm worried about this too. I've got dual SVS SB-2000s (12" sealed) right now and am not impressed in my large space. These are 15"s and THX certified meaning they can hit higher output levels. I was thinking I'd need to go to dual ported 15" but the deal on this monoprice sealed really has me tempted....

There's just not a ton of professional reviews (Ex: audioholics) on the monoprice sealed line for us to read up on yet...


EDIT:

Actually here's a nicely written review from AVSForum's Jim Wilson:

I think I'm in for 2x of these bad boys :-)

How large of a space are you talking? I just picked up an SVS SB 2000 and hope it fills my 25x14 sized room well. I had heard great things about it.

Price is good but I just noticed that 2 x 12" subwoofers are needed to meet THX Select certification. I own a 12" ported Monolith, one of these is THX Certified Ultra. Looking for a subwoofer for my basement, will wait for the ported subwoofers to go on sale.

My living room is about 2000 cu ft, but it attaches in an open layout to another 1000 cu ft den and 2000 cu ft kitchen/dining area, so all in all from a bass perspective its close to 5000 cu ft.

I should also add, it wasn't just an output/volume thing. I was expecting it to dig much deeper and it rolled off pretty quick around the mid 20 hz's. It was definitely clean and tight though vs. my old Polk PSW505 12", but this monoprice 15 looks like its got some good output sub 20hz even.

My wife didn't like me buying the ported 10 inch...I wonder if she would notice a sealed 15 inch in its place?

Ahh. Really large space(s). I think I'm good! Haven't fired it up yet, and do have some relatively open stairs to contend with, but I think I'll be fine. Thx.

Large sealed subs and are accurate and can extend low.

How do these hold up against HSUs in similar price range?
