Thank you for the quick response, but I've actually been a member here since 2013, lol. I just don't post very frequently. The Onkyo receiver I mentioned was powering a pair of RF-7's in my dedicated home theater room in my basement.

I know this thread is old, but I wanted to get some feedback from those of you who have had a chance to live with the Jamo s809's. A recent remodel and rearrangement of the layout in our living room means that it's finally possible to upgrade from bookshelf speakers for the TV to floorstanders, but the wife will only go along if the speakers are white and not more than $500 or so. That makes it kind of a narrow field, but the Jamo s809 seem like the obvious choice. To power them, I could keep using the Sony STRDH190 basic stereo receiver (100Wx2 @ 8ohms) that I've been using with the bookshelf speakers, or I could use my beefy Oknyo TX-NR818 (135Wx7) that I decommissioned last year from my home theater due to its lack of 4K support. The Onkyo also has Audyssey MultEQ XT32 room correction. Or, in the spirit of minimalism, I was flirting with idea of getting one of those little Class D stereo amplifiers off Amazon, something like so: https://www.amazon.com/Audio-Amplifier-Receiver-Integrated-Speakers/dp/B076P2VS9H. My wife likes the idea of getting rid of larger components, but I don't know how those little amps would do with full size speakers in a medium sized living room, especially since my girls like to listen to some of their pop music at volume. Anyway, any thoughts on the Jamo's are appreciated!

I have a pair of Chase Home Theater (CHT) VS 18.1 subwoofers (monstrous 18" vented speakers) for my home theater that I'm wanting to upgrade the drivers on. I'd like to swap out the stock (and rather pedestrian) Eminence drivers for Dayton "Ultimax" UM18-22 drivers. The only problem is that the UM18's are about 1/4 inch larger than the stock drivers, so I'll need to enlarge the speaker opening a little bit. I'm not a woodworker myself, so even if I obtained the tools I would probably still mess it up. I don't want to butcher my cabinets, so I was hoping somebody might be able to recommend a competent woodworker to hire in the Indianapolis area who they would trust to cut into their own speakers. Thanks!

I'm sorry, it already sold for the asking price. I'll see about updating the thread. Thanks anyway!

Bump for price reduction!

Yeah, pound for pound and inch for inch, I think the MiniVee is hard to beat. I've found that by adding more-compact options to my camera kit, I'm much more likely to take my cameras out and shoot with them. I picked up the Panasonic GX7 last year, which is an m43 camera, and it gets way more use than my APS-C DSLR. It's amazing how small and light the lenses are. I own an m43 fisheye lens that I could literally slip into a jeans pocket (Olympus 9mm fisheye). And I've also owned some of the high-end compacts, such as the Panasonic LX-100 and the Sony RX-1. It's amazing how much quality they can squeeze into a small camera, as long you're willing to pay a little extra for it (kind of like the MiniVee!)

That's actually one of my favorite features of the UM18, and for me it could be a deciding factor, even if a competitor had slightly better performance.

So are these supposed to out-perform the UM18's?

SPEAKERS HAVE SOLD FOR THE ASKING PRICE I need to fund a big subwoofer upgrade for my home theater so I'm (reluctantly) offering some nice speakers for sale. These are the ELAC Debut B6 speakers which were recently released as part of Andrew Jones's new line of speakers. The professional reviews of the B6 are almost universal in their gushing praise for the speakers. Here's a link for the offical AVSforum review, as well as a couple others, all of which describe much the same thing: Class-leading value and sound. If you're not already familiar with these speakers, then you owe it to yourself to check out the reviews. http://www.avsforum.com/elac-debut-b6-bookshelf-speakers-review/ http://www.cnet.com/products/elac-debut-b6/ https://parttimeaudiophile.com/2015/12/19/review-elac-debut-b6-and-f5-loudspeakers/ I'm asking $230 shipped for the ELAC's, and local pickup is available. I also have a Velodyne MiniVee listed in a separate ad.

Sorry, it's the 8". I don't think the 10" is made anymore, so the "new price" in my post refers to the current price for the 8". I'll update the original listing. Thanks! FYI, I also owned the 10" model in the past. Although I never listened to both side by side, the performance is very similar from what I recall of the 10". I remember seeing frequency graphs of the two subs at some point, and it seems like the 10" went a bit deeper, but the 8" had a bit more volume in the mid-bass range. The 8" model has a smaller cabinet, and is approximately two inches smaller on each side than the 10" model, so it is easier to hide. (10.9"x10.4"x12.8" vs 12.75"x12.375"x14.5")

Thanks, photography is my other hobby. Whenever I have some spending money to play with, I'm always torn between audio/Home Theater gear, and a new lens!

SUBWOOFER HAS SOLD FOR THE ASKING PRICE I need to fund a big subwoofer upgrade for my home theater so I'm (reluctantly) offering some nice speakers for sale. Up for grabs is the mighty Velodyne MiniVee subwoofer. This is a sealed subwoofer with an 8" driver powered by a 1000W RMS /2000W "Dynamic" power subwoofer. The crazy thing is how tiny it is...approximately 10"x10"x12". This tiny little sub is solid though, and at 33 lbs it feels like you're picking up a cinder block when you move it. Given its small size, it's perfect if you need to hid a sub but don't want to sacrifice sound, or you just want something smaller, such as for use with a 2.1 computer speaker system. Reviewers and owners rave about the performance of the MiniVee, and here's a couple links to reputable professional reviews: http://hometheaterhifi.com/reviews/speaker/subwoofers/velodyne-minivee-subwoofer/ http://www.audioholics.com/subwoofer-reviews/velodyne-minivee I'm asking $430 shipped for the subwoofer, and local pickup is available. I also have a pair of ELAC B6 speakers for sale in another ad.

If they want to delete all that, I don't mind. Iv'e got the text of my original post copied. I'm hoping that Parts Express tech support responds with helpful help on Monday. If I still need help after that, I can maybe start a new thread.

That would probably be best. I wonder if a moderator is able to pick all this up starting with my post from last night and put it in a different thread?

Looking through the comments on that YouTube video, there are all kinds of criticisms of the methodology there. This electrical measurement stuff is all over my head, so I'll probably not go further down that road. I've just sent an email to Parts Express tech support to get their thoughts on amp selection.

Only if your testing a car audio amp. https://www.youtube.com/watch?v=Zq2goZXCbMM Okay, thanks again. So you turn up the gain until you can hear your speaker distorting? Is there any danger in that? Does it matter if the speaker is in, or out of the box? Is it easier to hear the distortion with the speaker in free air?

Hmmm...the youtube video's I'm looking at show that you need a multimeter AND a clamp meter to test for wattage output on an amp. Is that right?

Should I be sending any particular frequency(ies) to the amp during the test?

Is this while the amp is hooked up to the speaker?

Makes sense. I actually do have a multimeter though. How should I use it during the test?

Pulling it back out to test it would not be a problem. What procedure do you use to test it? What do I look for? How high do I set the gain? etc. I don't have any fancy equipment, but I can run one of those online tone generators from the computer.

This thread has been in the back of my mind the last couple years, and so I finally decided to dip my toe into the DIY waters. I wanted to start modestly before jumping in whole hog, so I ordered a 3.0 c/f flatpack from Parts Express, as well as a Dayton DCS385-4 15" driver. Even though my ultimate plan is to build a couple 18" subs using the UM18-22 driver, I figured that I would be able to use this 15" sub somewhere else in the house, or maybe resell it on Craigslist and get some of my money back. The build went fine (although it was more work than I expected) and the sub looks good, but I'm having some trouble with it. It sounds okay and can make some decent bass, but whenever I try turn the volume up to get a more satisfying amount of slam, the woofer makes popping noise in scenes or passages where the bass gets really intense....where it goes low and loud. When I dial things back, it sounds fine. But at that point, the overall sound is not much more impressive than running my RF-7's by themselves. So the sub works, but it's just not very impressive. At this point, I wouldn't trade it for my 8" Velodyne MiniVee, or even my BIC v1220, which is only $188 new. Can anyone tell me what those kinds of sounds mean? Does it mean I'm pushing it too hard? Is it trying to go too low? Or does it maybe need more power? I'm using a BASH 300s amplifier for it. It's the amp that I normally use for my Tuba HT, and for that application it is more than enough power. Is this amp simply too wimpy for a big sealed sub? According to the specs, the driver is rated for 300W RMS/600W peak. At this point I'm feeling pretty discouraged, like I just flushed about $300 and a weekend's worth of work down the drain, so any advise would be greatly appreciated! My wife doesn't let me get away with spending too much on my toys, so any money wasted hurts!

I still think about going the sealed 18" DIY route from time to time, but my Tuba HT is doing such a good job that I can't get motivated to switch. I'm sure my wife would appreciate the smaller, less obtrusive subs, but I don't feel like going through the trouble of finding a buyer for the Tuba HT. I think I got a pretty decent deal at $500 w/ the amplifier, but getting my money back would probably require finding a very specific buyer, and I don't like losing money on my hobby transactions (I usually *make* money when selling old gear, since I try to buy low). Besides, my next project needs to be eliminating rattles and buzzes around the basement before I even think about going after more low-end.

Bummer...I got a notification, and I was all excited to see what the update was. I really enjoyed reading this thread.
