I want to use a high-pass filter on my system. Do you make them? What information do you need?
Unfortunately, we cannot make them.
However, we can get you the necessary information needed to make them.
There are 3 things we will need to know when helping you make a high-pass filter:
- Input impedance of your power amp (typically 10,000-100,000 ohm)
- Desired -3dB roll-off point (Ex: 40Hz, 70Hz)
- RCA or XLR
This will allow us to calculate the capacitor value needed for your desired roll off.
The values are quite small, and we always recommend getting the best quality capacitor you can as your entire signal is passing through this capacitor. We typically recommend copper-foil caps like Miflex KPCU03 or KFPM or from other notable brands like Deulund JDM, Jupiter, V-Cap etc depending on the sound you are shooting for.
Note:
If you change amplifiers, the filters will need to change as well.
The capacitor value will need to be adjusted according to the input impedance of the new amplifier.
High-pass filters cannot be used with integrated amplifiers. (Unless they are connected to a separate power amplifier(s))
AV-Receivers typically have a high-pass filter already built into them by setting the speaker size to “small.” Some my also offer edjustable roll off points. recommended range is 70Hz for bookshelf speakers, and 40-60 lower for large tower speakers.
What will it cost to upgrade my speakers?
We don’t know. We are not psychic so here is the deal. In order for us to tell you anything about your speakers we need one of them here. That means, you must ship one to us. If you send us an email asking us how much it will cost to upgrade your speakers and hope we can just guess what it needs and what it will cost, it’s gonna be a waste of time for both of us. If you still have questions, then send us an email.
Do you ship Internationally?
Yes, we do ship all over the world! If you need assistance with shipping quotes, please make sure you provide all the items you would like to purchase and the full shipping address! We cannot give a shipping quote without this information. Thank you!
Can you upgrade my crossover?
What time can I call you?
Is the price for one speaker or the pair?
Can you upgrade or repair my speakers for me?
Can you install your upgrades for me?
Can I swap out my speakers/drivers for yours?
How do you know your "upgrades" will improve my speakers?
All you do is make a flat line! Flat speakers are boring!
Can I buy just the schematic for your upgrade kits?
No. We do not sell the schematics on their own. We pick the parts to get you the best performance for your money, and some parts may be more of a lateral movement than an upgrade. There may cases where you’re getting more performance but not always going to be the case.
If you need to save on international shipping costs, we can remove the No-Rez upon request to bring down the shipping costs, VAT or duty.
