What is the frequency response of this OB-7 without the built in subwoofer?

Daygloworange · « **Reply #21 on:** 1 May 2007, 12:07 am »

I believe Danny said it would start rolling off in the 80Hz region.

You can see all the measurements on the GR Research OB 7 page:

Thanks for the info. The OB-7 just doesn't seem like the OB-7 without that sub in it.

Danny can you confirm what the difference in bass quality would be with this design please?

(I was wishy washy between this and the OB-5... Dammmmmn I should have just taken out that offer on the demo pair of OB-5's in Detroit...

The quality will be great. It just won't play as low as the model with the built in sub.

It does offer some flexibility though. Sometimes the best place for the speakers is not the best place for the sub. The sub can then be placed where it needs to be.

The box is easier to build too, and less expensive to have built.

I think these will become the new OB-7, and the older version with the built in subs can be the OB-7.1.

I have more woofers on the way and they will be here shortly (more M-130's and the new M-130X). They just landed in NY and will be here in about a week if they don't get held up in customs for scans again. I should have them within the next ten days for sure.

Denny is sending me a single MDF box for these. I will use it to try the new M-130X woofers and make sure there is no network changes needed and if so make any adjustments and tweaks to it.

The ne OB-7 kit will be just as Denny's renditions show it.

The standard kit will be $895 and it will be $995 with the M-130X woofers.

I'll offer a special on these for the first six people that order them with enclosures from Denny either fully assembled or just kits and enclosures. I'll knock $100 off of the kit price.

How does customs collect the charges, is it from the receiver or the deliverer? How can we find out what it costs for importation? (It puts me off a bit that we can't even estimate this -I don't want a 500 dollar surprise or anything)

Can we get a shot of the back of the OB-5's wired up to see how you manage the wire's appearance?

How tall would you estimate them to be in this new configuration? -about the same height as OB-5, ~50 inches?

Also, I saw in previous post you were charging for the foam lined crates... what is cost there?

sorry for all of the questions... but I am sure the answers will benefit more than just myself. These look great and I really would like to get them if I can get these concerns addressed.

I will jump IN and answer this.

Building cabinets or assembled speakers in Canada and shipping to the USA there is NO duties applied.
As have a free trade agreement between Canada and the USA.

The same applies if purchasing cabinets or assembled speaker from the USA into Canada.

Now there is a broker fee to clear the goods and if all the proper papaer work is filled out NAFT (North American Free Trade) with a company receipt this is all that is requested.This broker fee is applied by what ever carrier is used if that is a freight company or FEDEX,DHL,UPS etc.Fees range all dependant on the paper work that was provided to the shipping company when they pick up the items.(we provide all the proper documents when we ship to USA or International)
This fee can range from $25.00- as high as $250.00 all dependant on the paper work and the declared value of the items.

And believe me you do not want to under declare the items , if Customs inspects them and finds the value higher you are open for commercial fraud.

Really as long as all the paper work is filled out the broker fees can be calculated from the shipping end as we do.
This means a customer in CA or FL when the items arrive from US there is no charges at all.

We have been doing cabinets for Danny's customers as well as Danny for several years now and no one has ever paid any duties.

Now tax's will apply if you have a State sales tax, other than that no Tax's apply coming from Canada.

No goods coming into Canada have all the tax's applied on the receiving end.

Hope this helps.

This is how I wired up my pair of OB 5's. I can wire them up differently if you prefer. I kinda like the hot rod look, so I did mine up like this.

Yes, the OB 7 (hybrid) will be the same height as the OB 5.

Cost for the crates lined in 2" foam and packaging the speakers is $150.00 for the pair.

There are no duties or taxes from Canada into the U.S., we will cover the brokerage fees. All you pay for is the shipping and insurance on the full value of the speakers. Just PM or email us your zip code and we can give you an estimate on the freight and insurance.

The first OB-7 with the side grills removed.

Vapor Audio · « **Reply #28 on:** 1 May 2007, 11:30 pm »

Hey again Danny ... you remember me asking about building a setup for my Uncle in a large room, needing high dynamics? Well I took my MTMWW's over there and they fill the room just fine - and he's not too keen on the size of an array. The room is also really open, he does a lot of listening while in the kitchen. So what I decided was open baffle. I was planning on ordering all the stuff to build essentially what you're talking about here, this sans-sub OB7.

I was glad to see you're going to make this a kit now, I was just going to come up with a design myself. So question is when will the kit be ready with the 130x drivers? I'm also going to need essentially an OB-5 kit to use as a center channel too.

Denny,

Replied to your quote -- just want to let you know in case I landed in the spam file again.

Jim,

I'm just getting caught up on my emails. I'll be answering your questions tonight.

Well one more thing to add to the paper work for US items over a un named value.As UPS,FED EX and DHL will not set a dollar value were this needs to apply as it is the US Customs who is asking for this.

When sending high value goods (as noted what they see as high value changes from day to day) US Customs wants a IRS numberr of the person or business were the goods are being sent to.

If you do not supply the shipping company with this IRS number ,it can be weeks before you find out if they even call at all to request this info.

Just a heads up

Our first customer OB 7's are finally being assembled, so I thought I would post a few pics. There are a few things we've done differently to this pair of OB's. First is that we've actually angled the bottom of the speaker. The speaker now leans back between 3 and 4 deg. The top is angled down slightly as well. We sent Danny a test enclosure a while back with the new configuration of 4 woofers on the bottom, and tilted it back to see if it would do any harm to the response. It checked out fine. There was a slight change in the network due to the open baffle section being totally free air.

These OB 7's have the optional M-130X (XBL^2) woofers in the lower section.

The wiring in this speaker is something that was suggested by Jeff at Sonic Craft. We are using all high purity CCC. It gets more interesting. On the woofers, we are using 14 awg stranded CCC. The + and - leads are twisted together at one twist per inch,(2 conductors) and shrinkwrapped. The mid-woofer have 2 runs (4 conductors)of 18 awg solid CCC. The + and - leads again are twisted at one twist per inch and shrinkwrapped. The tweeter has one run of 18 awg CCC twisted, and one run of 23 awg CCC Silver twisted along with the copper,(4 conductors total) and shrinkwrapped together. All wiring is Teflon coated.

All the caps are Sonicaps, bypassed by Sonicap Platinums. These speakers are set up for external crossovers, that will be Faraday shielded. As such, there are binding posts for the 3 sections (M/T/W). The backplate is done in carbon fiber, and finished in gloss epoxy.

We've finally found the time to finalize the design of the bases, they definitely add to the overall look. They are finished in a charcoal grey metallic pearl. I've tried to highlight the curves that we've incorporated. Not only are the sides curved, but the baffle front as well. I'll post some better pics shortly.

Cheers

Nice looking Denny well done

My goodness, what superb looking speakers. They look refined and elegant.

Hank · « **Reply #35 on:** 28 Jun 2007, 02:35 am »

Beautiful work, Denny! I particularly like the large radius relief on the edge of the woof recesses.

gprro · « **Reply #36 on:** 28 Jun 2007, 02:37 am »

NICE!

I'm starting on mine soon. Couple questions. Are those custom BG housings? Mine are perfectly round, no coutout for the mids. My kit is a little older though, I'm having it upgraded with new x-over parts and the 130x's. I'm wondering if the tweeters need these housings to react properly with the tweaked x-over (closer spacing to the mids)? I was thinking of doing external x-over also, got any pics?

Danny Richie · « **Reply #37 on:** 28 Jun 2007, 02:42 am »

Dang those look good.

Are those custom BG housings?

No. It is the stock (and latest) face plate. The mids overlap onto it to get a closer center to center spacing. Yours will too, and the older face plate will give you the same response.

gprro · « **Reply #38 on:** 28 Jun 2007, 02:46 am »

so no need to send back the face plates, my mids are round also, they are going to be spaced farther? I'm mailing everything tomorrow, a few days late, can I get some new face plates also, i could still add them in?

The GR woofer drivers are a flush mount design with an incorporated gasket. No recess is need for the woofers. The BG face plate is recessed flush with the face of the baffle, and then the woofers partly overlap the BG faceplate. I'll take some closeup pics of the MTM section.

I'll post pics of the crossovers when I complete them. They'll be housed in separate boxes. One for each network, so 6 boxes total.
The customer will be biamping these OB 7's, and will be running a pair of active subwoofers alongside these in stereo. Nice!!

Thanks for all the compliments. I've incorporated a couple of changes since the OB 5's that I think have added up to a really nice aesthetic.

Now it's time to rock these bad boys!!

Cheers
