It rocks....:D

We have alot on the frying pan right now but not enough chefs to get it all done as quickly as I'd like ;( Our 22 page review of the Yamaha RX-A3000 is scheduled to post Dec 27th!

This is a sub I just recently found out about that I plan on reviewing next year to compare to the Emo. It looks like it will give the Emo a run for its money! Well it's more expensive than the Emo but you get my drift :) http://svsound.com/products-sub-box-sb12nsd.cfm

The best constructed sub of the bunch is the JL f110 by a mile but its also very pricey. The Emo is built very well as you will see in our review.

As a teaser, I took all my 1 meter sinewave sweep tests for the UL12 and 3 other subs I recently reviewed and compared the data in tabulated form. Please note these are NOT max discrete SPL#'s like CEA2010 testing produces. Instead these are continuous fullbandwidth power sweeps that test for...

Emotiva UPA-7 Review Not a bad little amp IMO ;)

Oh geez. The backpanel power rating is NOT a max power rating unless it states it. It's typically 2 channels driven at full rated power for 2CH amps/receivers so 140wpc x 2 + say 50 watts for processing / 0.5 eff = 660 watts but for multi channel receivers they typically run 1 channnel at...

All; I am the last in my family to get strucken by a nasty stomach virus today hence why I did not post the article. Hopefully tomorrow.....

Update The measurement protocol will be published tomorrow, not the actual measurement results. Those should start coming in after the holidays as individual reviews of each product and then a shootout summary of results article.

I directly compared my measurements of this sub to: JL Audio f110 Axiom EP 400 Aperion Bravus 10D I used 1 meter groundplane RMS sinesweeps not CEA 2010 burst testing since we didn't develop a test procedure for that at the time I measured the other subs. All subs were measured using...

There have been several very large loudspeaker companies that have improved driver and component parts as a result of our reviews dissecting their products and discussing them. Some are appreciative of our feedback, some are NOT :eek:

I just finished writing up my measurements report on the Emotiva UL12 subwoofer. What an incredible performer for the dollar. I compared it directly against my JL f110 and Axiom EP400 which will be in the review. Anyone ignoring Emotiva subs should reconsider.....

Nothing terrible about electrolytics if the designer factors in the added ESR inherent with these type of caps in their crossover design. They aren't as linear as polys, especially at high power levels as another poster mentioned. Personally, I prefer to see poly caps in series with the...

I am a bit surprised to see that too, especially since they paid proper attention to orientation of the chokes. I asked Mark to comment since he did the review. Perhaps there are some poly bypass caps we can't see in the photo.

Only 4 subs in this Shootout We found some design issues with the Salk and an amp issue with the RBH sub so neither will be in this shootout. We will review the RBH sub next year as a dedicated review and update the data in the pending shootout with its data and all subs data that we test...

Update: First article coming Paul just finished his article on Subwoofer Measurements & CEA Testing. It should post live by Monday of next week.

Bandphan is a regular forum poster and a new recruit for us to write reviews. His name is Scott Coleman. We lost communication with him about 2-3 weeks ago. Right before his last email to us, he stated he completed his Lava review and sent it for peer to us but we never received. I tried...

I really love when Tom writes these type of articles as you can be sure within 2 business days I hear hell from the manufacturers he singles out. I just had a lovely conversation with one in particular :eek: It's nice to know that the manufacturers pay attention to our articles, especially Toms :o

Correct, also lower distortion too. Very few amplifiers are fully balanced from input to output however.
