Would love to hear from the manufacturer regarding these discoveries!

I used bought and installed Danny's SVS Ultra Bookshelf upgrade with full norez installed as well. After the appropriate burn-in period I have been truly amazed at the improved sound. I cannot thank GR Research enough for great products, research and support.

Another valuable lecture, thank you Danny, just watching this relaxes me :)

Thanks Danny. Ordered the bookshelf upgrade. Almost finished with the center channel upgrade.

Hello from Denton, TX. Enjoy your videos. I'm thinking about some SVS speakers this summer and found this very interesting.

Can’t wait to see the before and after on the towers

I completed the upgrade on my two Ultra Bookshelf and Ultra Center speakers. Sure, it takes some work but it is well worth it. Vocals are the standout improvement. I listen mostly to multichannel SACD classical. Soloists and Choirs are all improved. Much clearer. Overall improvement in instrument clarity. Now, given my results, I wish I could afford Danny's open baffle speakers.

Hi Danny, very interesting video. Improve you can certainly always something...there would be the question of whether expensive crossover parts also always dramatically improve the sound...that would be interesting to see how you test old against new in the sound comparison. Frequency curves are one thing, but sound in comparison much better to understand or hear.

North Texas sounds like heaven ;) If it's any consolation, living in a tropical climate isn't all beer and skittles - the heat melts your brain. No question - at least for me - that far more work gets done in a temperate climate and your efforts are proof of that. Thanks for the vide.

Cold and wet, nasty in Sand Springs, OK also. Thanks for the tech talks, Danny!

Could you do a video for the DIY crowd for a 3 way speaker and recommendations on what woofer, mid-range and tweeter choice & 3-way crossover on a budget?

I love this channel and I think that it's awesome to see the knowledge that Danny has! A question that I have been wondering about is what entry level/budget speakers roll off the line with decent internals and drivers. Say sub $1000.

Hey Danny I'm very much interested on doing the replacement parts on the svs ultra towers, will you be doing another video by chance on the step by step ?? Thanks

Here are some of the reasons manufacturers do this : - Majority of people would never know what’s inside their speakers as they can’t access them. - It’s the best place for manufacturers to make extra profit. - Since most use the same or similar drivers in their products selling you an upgraded “ high end “ versions allows their customers an upgrade path. FYI: Some new speakers are sealed and glued in so you can’t get in without damaging them. I was able to upgrade my old pair of B&W Speakers but not my new Wharfdale EVO’s.

Thank you Danny! That was awesome. I've owned and enjoyed the Ultra Bookself speakers. At the time I was obsessed with finding the best value bookshelf and with U-BS side-by-side against Buchardt S400 found them different but essentially equal. Since U-BS are priced lower, gave the win to SVS on that comparison. I agree that the cabinets are very good, and despite these (easily-corrected) crossover issues, they are a very good choice for bookshelves. I moved on to floor-standers; otherwise, would have kept them. I did keep the Elac D2-6.2 (for the garage), because those were (by far) the best value at $200/pr delivered new. Think about this... you could buy 5 pairs of Elacs for cost of one pair of SVS Bookshelf - create a wall of Elacs (not that it would be a good idea - but you get the point).

Love your work and video presentation. Finally someone online who knows what they are talking about has a love for what they believe in. Question thou. Do you rebuild crossovers for people who live in Australia.

Thanks Danny! just last weekend live cast by Ron @ New Record Day discussing if you have an upgratde kit for SVS bookshelf's. Would you be undertaking a project for SVS Prime bookshelf - same price point as Kplish;s RP 600? It's disappointing knowing SVS that advertises and personalizes messages as to high-quality parts to cut corners; like for cross over how much would it cost them (buying in mass) to use at least a reasonable level of conductors etc.

you have got rid of 1 problem in sounds but you have a bump in brighter areas that should have been lowered

Hi Danny. Any chance of Ron doing a sound comparison of the stock SVS Ultra Bookshelves to the modified version? I think that was great when you guys did that with the Klipsch! I’m sure there are a ton of Ultra owners that would agree.

Thank you for the video re ultra upgrades. I really look forward to doing the upgrades once you have it. Can I ask! Is it something complicated to do to upgrade them.? Or will it be a plug and play upgrade.? I am thinking of buying these as a front tower and currently have the pb4000 svs, also ceiling speakers and rear. So to compliment my set up I thought of buying these ultra towers. Thank you once again so much, really interesting video

the per unit price is because SVS does a lot of home theater, and people will buy a single speaker for the middle channel. Some people prefer to not buy a horizontal center channel and will by a regular speaker. Often this is done by people who put their speaker behind an acoustically transparent screen.

Have you ever worked on Definitive Technology speakers? I have a set that I'd love to do some upgrades on.

Regarding the before/after graphs, what about that sharp little hump at 5Khz and the dip at 400hz? I guess the average is balanced but that still seems noticeable.

Danny's check list would be, after driver quality & placement on baffle, & baffle, not too wide- --then we examine the bracing & damping of the box; damping, ferro-,magnetic connector material (from drivers to crossover & to spkrs box connectors), - cheap crossover parts, just match, pay more, and get more without changing the deign. Danny confims that proper wire gauge matters, all the way from drivers back to the amp. With a software I presume golks could do their own measurements & change rolloff, tapering - but minus that, the other stuff is simple * logical - didn't know half of it, put drivers all over the baffle, when we built Philips kits in the 70s - used their cheapo crossovers pre-assembled if I recall My goal oow, remove tiny push/pinch connectors; remove level controls for mid & high - solder at drivers where we used crimped female spades - relocate mid and hi drivers to center of baffle. Two tweeters will be left over - we thought more, was better. Not so, as we learn from Danny!. Gauge damping & stiff walls, those we got, via flake particle board 3/4, doubled all around, with 2 bottles of Boandfast & Robertson screws

Hi Danny! As usual good video! Why the hell are there so many speaker manufacturer still use these huge and probably expensive biwiring posts. Imagine if they used one set of tube connectors.

They’re my first “real” speakers. I understand they’re not anything special and im not emotionally attached to them. I wont be offended if they’re not great. $600-something just seems like it would go farther towards a new pair of bookies. Also i have enjoyed my bookies but hate the center channel. It sounds flat and shallow.

Wow this is getting so 😎

I watch lots of your videos and decided to build my own tiny monitors out of some old stuff I had hanging around. In addition to the many changes I made to the box (an Infinity RS1 Bookshelf) I switched the filters to little first order. A SonicCap cap on the tweeter, an aircore on the woofer, no resistive or inductive L-Pads, lots more stuffing of the box, a very thick MDF baffle. What a difference! It begs the question, while I understand the one cap in my "new" speaker cost more than most companies spend on an entire crossover (or speaker!), I don't understand why it's primarily high end companies who use simple 1st and 2nd order crossovers with superior film/PIO/Silver in Oil, etc. caps on the tweeter. And for gosh sakes, polyfill, fiber mat, and stiff foam are cheap, stuff the damn cabinets! Do you have any insight? Thanks.

One thing I've seen with audio and video products is they often are selling a perception of quality more than a measurable quantifiable quality. That is, if their speakers 'sound' great to most people, why take a hit on margins by replacing the guts with better-measuring components if most people are already happy with how they sound? That all being said, it would be nice to do a blind A/B listening test between unmodified and modified speakers here to see if the measurable improvements end up being actually perceptible to the listener.

It does give a better clarity to upgrade the crossover. Just buy new caps with the same value for the tweeter circuit and you get rewarded direct. Go all the way with inductors, resistors and better binding post and internal cables, then you get even more rewarded. This does not change the measurement. Stiffened the cabinet inside with dynamat (car use) and some poly fill and you got a really great speaker. New crossover parts needs 100-300 hours of playing.

It is not only the quality of coils and capacitors that gives you good sound! If you have a speaker that does not have good sound, it is not just a matter of switching to high quality parts and you get good sound. You need to design the crossover filter properly to get good sound and then you can switch to extra good parts. In your videos it sounds like you are only using a measuring instrument but you are not listening to the speaker which is just as important!

The filter network measured fine. If the slopes and integration between drivers measure well, that's all you can do. The measured response will correlate with the listening. Other than replacing drivers entirely ( which makes no sense since you might as well get other speakers) all you can do is upgrade crossover parts which is the gist of the video.

I have built many speakers and do not agree. Example, if you have midrange / bass and treble in a box and have assembled the crossover filter in a certain way using capacitors coil resistors but do not get good sound, then it does not help to switch from cheap polypropylene capacitors to expensive or switch from cheap coils with expensive! If you have a lot of 400hz in the speaker then you need to make a circuit that lowers that frequency!
