Introducing the New model B-4 active two-way analog crossover with about 400 Million possible settings!  The B-4 is a tremendous value for high performance and flexibility with easy adjustment and is unique in several ways:

First, it uses only direct-coupled matched discrete complementary Jfets (the now unavailable Toshiba 2SK170 and 2SJ74) in unity-gain buffer circuits without feedback. These buffers allow accurate interface between a very wide range of impedances in the filter components. They are adjusted for zero DC offset and do not require coupling capacitors. The filter resistors are high quality 1% Vishay commercial metal film types, and the filter capacitors are Wima polypropylene film types.

Second, the B4 has a fantastic range and variety of filter values and characteristics. Each of the four filters offers 1, 2, 3 or 4 “poles” for each filter, corresponding to 6, 12, 18 or 24 dB/octave slopes. Each of these filter poles is independently adjustable within each filter, allowing wide customization of the character of the filter. Each pole is adjustable from 25 to 6275 Hz in 25 Hz increments, which is 255 settings per Pole, and the possible number of settings for the four poles of each filter is something like 400 million.  With a few simple switches, the B-4 can accommodate “Sallen Key” values or “Linkwitz-Riley” values.   All settings are available without a soldering iron or buying additional components.

The owner’s manual for the B-4 is posted on  More pictures and special offers are on  The B-4’s input impedance is 10K ohms, which will work well with solid state preamps and not with most tube preamps.  There was a "B-4" released years ago-- today we have an All-New B-4.

This ad is for a NEW First Watt B-4 with full three year transferable warranty and Satisfaction is Always Guaranteed from Reno Hi Fi! Includes all factory accessories, owner’s manual, factory AC cord and new factory boxing.  The supplied B-4 power supply has an IEC plug, is auto-sensing, and will work on all standard line voltages worldwide.  We ship worldwide except where First Watt has other local representation: Japan,  Hong Kong, France, Germany, Poland, Italy, England, and Singapore.

Return Policy
Return Window

Item can be returned within 14 days of receipt.

General Terms

Items must be returned in their original condition, with all included packing materials and no signs of use. Buyer assumes responsibility for all shipping return costs unless the item was not received as described.


Buyer will receive a full refund in the original payment method less any shipping charges.

Special Conditions

In keeping with our dedication to client satisfaction, Reno Hi-Fi, Inc. has an extremely generous return policy. If for any reason you are not completely satisfied with your purchase from Reno Hi-Fi, you may return the item for a prompt and full refund, less only the actual round-trip shipping charges. Reno Hi-Fi does not charge a restocking fee, handling fees, credit card processing fee, nor any other kind of fees for returning merchandise.

Returns are to be shipped to the return address on the outbound shipping label. Returns must be shipped no later than 14 days after the item was received; on the 15th day all sales are final. Returned items must be received in the condition in which they were received, with all accessories, including the owner’s manual, AC cord and remote control (if applicable). We recommend UPS or Fed Ex shipping with insurance equal to the sale price of the product (so that your investment is protected) and “signature required at delivery,” so you have proof the item was received by us.

Within 24 hours of our receipt of the returned product in proper condition, we will refund your payment, less only the price of the shipping that Reno Hi-Fi incurred. We almost always refund your payment via the same payment method with which you paid us. PayPal and credit card payments are simply reversed, less the shipping costs. For credit card payments, we will very quickly issue the credit to you though the credit card system. Our finding is that banks are generally fast to charge and slow to credit. Credit card refunds usually take five to ten days to appear on your credit card account, even though we have very promptly entered the credit into the bank’s system and our checking account has been quickly debited. Even though the credit card refund may seem on the slow side, it will certainly reach your account—try not to worry. We’ve never had a credit card or PayPal credit not be applied as it should. Payments made by other forms of payment will quickly be refunded with a Reno Hi-Fi company check sent promptly by First Class Mail.

Our return policy is a great benefit to the Reno Hi-Fi customer. The policy is more than fair and insures that our clients are happy with the products they invest in though us.
