    WTB: Oris Horn

    Yes sir, I do! I love the open baffle sound. I built my H frames with eminence Kappalites since I had those on hand. They actually are not "ideal" for an OB design, but they work very well. The sound of an OB is like nothing I have heard before. Clean and clear. No free lunch, of course, so you can only go so low. That is where all my subs come in. Frankly, I started out doing the OB thing because I couldn't believe that a plain board with a hole and driver in it would actually work. Just amazing stuff when you dig in. I have built and tried many OB designs. Taken measurements and listened quite a bit to the various builds. The H frame was the best I could build while trying to balance performance and frequency range. I did build some types that had better LF, but they lacked range and didn't sound quite as good as the very simple OB H frame. My center channel is still a plain old OB! Sounds great. The whole Oris thing was to try and fully match my other main speakers. Not viable though, due to size. I will have to stay with the OB or look at some type of DIY low profile horn. There are not many options for 8" drivers. I once built a horn to mimic a Lowther 'top hat' horn, but it didn't sound good. Back to the wood shop I guess. With an Oris, the OB H frame is an excellent option. Super easy build!!! If you are unusre, you can take scrap plywood and build a prototype in 30 minutes. It's amazing just how good an OB sounds.

    What the heck was I thinking! There is no way I can add a center Oris to my HT and be able to see the center bottom of my 10' screen! I have a large room too. 20'x27'. I watched a movie tonight and realized there is no way to add a center Oris unless I set it on the ground for it to not interfere with the 10' screen. I will have to come up with a DIY horn or something else.

    I just realized the David Dicks you mentioned runs common sense audio. I just picked up 3 Alnico Super 8 Audio Nirvana drivers from him. I am waiting for him to get back from vacation to ask about the Lowthers. Now I know what he would have said.

    I did see where you can order the entire driver kit to repair directly from Lowther. Price wise, it doesn't make financial sense. Sending them back for repair to the UK would be equally unreasonable. So far, have not found anyone in the States that can do original repairs.

    If it's not a problem, can you PM me the contact info?

    sheltie dave, where did you send your Lowther drivers? I am researching a place that is familiar with Lowther driver repair. That horn seems to have the LeCleach curve. Interesting proportions...

    In my case, there is no behind the screen. I am curious as to how well a fully functioning center with an Oris horn will work in an HT environment. The price of new horns from Bert is very reasonable these days. The killer is shipping to the US. You never know, might just order another new set....not sure it will be worth it though. For now, I just got in three Audio Nirvana Super 8 Alnico drivers. I tested one against my Tang Bands and the Nirvana's are a step above and worth the cost of the upgrade. It will be a few weeks before I can get everything installed though. I have been looking for any other option of having a horn on the 8" driver and just can't find anything like an Oris. All in good time I guess.

    Just in case anyone spots a sale of an Oris 250. I am going to try and add one as a center channel for my HT.

    New ? Bass / midbass on 2 way speaker setup

    The only way to know what you will like is to experiment, as you are doing. Good luck!

    New ? Bass / midbass on 2 way speaker setup

    I would shoot to make the crossover point as low as possible, thereby allowing the full range driver to do as much as possible without the interference of a crossover and issues associated with two drivers operating in the crossover range. In my case, I have a non-conventional 3 way system. The HF driver is in an Oris horn which rolls off at 150Hz. I chose a 300Hz crossover to have plenty of hf performance before the horn ran into roll-off territory. So, my HF driver goes from 20kHz to 300Hz. The OB H frame drivers go from 300Hz to 80Hz. From 80Hz to 20Hz I use my RSW-15s in order to get a true 20Hz-20kHz capability. I have not found a better way to do it. For LFE I use 4 huge ported full Marty subs with 18" drivers. As we all know, in an ideal world, you would use a single driver for the entire frequency range and avoid any crossovers. However, that unicorn doesn't exist AFAIK. Your ears will be the ultimate judge, but I submit you will be better served with the full range driver covering the largest possible portion of the audio frequency spectrum.

    What would you do ? A question of Bass......

    Good question. I don't use the RSWs' amplification at all. Actually, over the years I collected 3 RSW-15's that had damaged amps. I ripped the bad amps out and provide my own amplification and active crossover. I had not given any thought on how to implement what you are trying to do, but I'm sure it is possible as you describe.

    IMHO I don't think adding another OB set of bass drivers is going to do anything if you intend on keeping a good balance between the bass and the upper frequencies. I have two OB 15" drivers per side, but have to attenuate the output vs. just a single driver. As you are well aware, the OB does have a lower limit of performance that demands some type of subwoofer if you expect to get to the lower frequencies range. Not to mention any sub 20Hz stuff for movies. In my case, use two RSW-15's that are actively controlled to go from 20Hz up to where the OB 15's are crossed on the low end. I suspect you would be better off setting up some type of subs to get that lower frequency octaves. The attached picture shows my current setup, although the RSW's have been moved to another location in the room to optimize and smooth LF frequency response.
