  • 5Right of revocation

Consumers (§ 13 BGB) have a statutory right of withdrawal.

Right of withdrawal

You have the right to cancel this contract within 14 days without giving any reason.

The revocation period is 14 days from the day on which you or a third party named by you, who is not the carrier, have taken possession of the last partial shipment or the last item.

To exercise your right of withdrawal, you must send us

ACR-Bielefeld Klangwerk GmbH,

Otto Brenner St. 132,

33607 Bielefeld

Tel: 0521-7871453

eMail: service@acr-bielefeld.de

by means of a clear statement (eg a letter sent by mail, fax or e-mail) about your decision to revoke this contract. You can use the attached sample withdrawal form, which is not mandatory.

In order to comply with the withdrawal period, it is sufficient that you send the notification of the exercise of the right of withdrawal before the expiry of the withdrawal period.

Consequences of the revocation

If you revoke this contract, we shall reimburse you for all payments we have received from you, including delivery costs (with the exception of additional costs resulting from the fact that you have chosen a type of delivery other than the most favorable standard delivery offered by us), without undue delay and no later than 14 days from the day on which we received the notification of your revocation of this contract. For this repayment, we will use the same means of payment that you used for the original transaction, unless expressly agreed otherwise with you; in no case will you be charged for this repayment.

We may refuse to refund you until we have received the goods back or until you have provided proof that you have returned the goods, whichever is the earlier.

You must return or hand over the goods to us immediately and in any case no later than within fourteen days from the day on which you notify us of the revocation of this contract. The deadline is met if you send the goods before the expiry of the period of fourteen days.

You bear the direct costs of returning the goods.

You only have to pay for any loss in value of the goods if this loss in value is due to handling of the goods that is not necessary for testing the quality, characteristics and functionality of the goods.

  • 6Prices and shipping costs

(1) The prices stated on the product pages include the statutory VAT and other price components, unless otherwise stated in the respective offer. In the case of used goods/articles, insofar as the legal requirements are met, reference is made to the differential taxation and the applicable taxes.

(2) In addition to the stated prices, we charge shipping costs for delivery. The shipping costs will be clearly communicated to you again on the product pages and on the order page.

(3) The delivery of the ordered goods takes place against prepayment, Paypal*, cash on delivery* or on account*. (* requires a separate agreement)

  • 7Payment

(1) Payment shall be made in advance, Paypal or cash on delivery. Payment on account requires a separate agreement. Insofar as "payment on account" is possible due to a separate agreement, this will be pointed out separately before the order process is completed.

(2) In the case of payment in advance, we will provide you with our bank details in the order confirmation and deliver the goods after receipt of payment, taking into account the stated delivery time.

(3) You shall only be entitled to set-off if your counterclaims are undisputed, have been finally determined by a court of law or are ready for a decision in a legal dispute or if they are counterclaims pursuant to § 320 BGB.

(4) You may only exercise a right of retention insofar as the claims result from the same contractual relationship.

  • 8Preservation of ownership

(1) The goods remain our property until full payment. If you are in default of payment for more than 10 days, we have the right to withdraw from the contract and reclaim the goods.

(2) You shall only be entitled to resell the goods subject to retention of title if we have agreed to the resale in writing. In this case, however, you already now assign to us all claims from such a resale in the amount of the invoice value of our claim, irrespective of whether such resale takes place before or after any processing of the goods delivered under retention of title. Irrespective of our authority to collect the claim ourselves, you shall remain authorized to collect the claim even after the assignment. In this context, we undertake not to collect the claim as long and as far as you meet your payment obligations, no application for the opening of insolvency or similar proceedings has been filed and there is no cessation of payments. Insofar as the above-mentioned securities exceed the claims to be secured by more than 10%, we shall be obliged to release the securities at our discretion upon your request.

(3) The customer is obliged to treat the goods with care. If damage to the goods occurs between purchase and return of the goods to us or if a loss in value of the goods occurs due to other circumstances, the buyer shall be fully liable for this, even if he is not at fault for this.

  • 9Delivery

(1) We deliver the goods according to the agreements made with you. Incidental shipping costs are listed in each case with the product description and are shown separately by us on the invoice. Delivery dates and delivery periods are only binding if they have been confirmed by us in writing.

(2) Insofar as we do not deliver the goods or do not deliver the goods in accordance with the contract, you must grant us a grace period to effect performance. Otherwise you are not entitled to withdraw from the contract.

(3) Delivery shall be made by sending the goods to the address specified by the Buyer. As far as delivery against prepayment is agreed, the delivery period within Germany is 7 working days after receipt of the purchase price and 10 working days for deliveries within the European Union (EU). Otherwise, the delivery period is 7 working days after dispatch of the declaration of acceptance.

(4) If the Customer is in default of acceptance or culpably violates other duties to cooperate, ACR-Bielefeld Klangwerk GmbH shall be entitled to demand compensation for the damage incurred in this respect, including any additional expenses. Further claims remain reserved.

(5) The risk of accidental loss and accidental deterioration of the object of purchase shall pass to the Buyer as soon as ACR-Bielefeld Klangwerk GmbH has delivered the object of purchase to the forwarding agent, the carrier or any other person or institution designated to carry out the shipment. This shall not apply if the Buyer is a consumer.

(6) If the conditions of para. 4 are met, the risk of accidental loss or accidental deterioration of the object of sale shall pass to the customer at the point in time at which the customer is in default of acceptance or debtor's delay.

(7) ACR-Bielefeld Klangwerk GmbH shall be liable in accordance with the statutory provisions if the delay in delivery is due to an intentional or grossly negligent breach of contract for which we are responsible; fault on the part of our representatives or vicarious agents shall be attributed to us. If the delay in delivery is not due to an intentional breach of contract for which ACR-Bielefeld Klangwerk GmbH is responsible, our liability for damages shall be limited to the foreseeable, typically occurring damage.

(8) ACR-Bielefeld Klangwerk GmbH shall also be liable in accordance with the statutory provisions insofar as the delay in delivery for which we are responsible is based on the culpable breach of a material contractual obligation; in this case, however, the liability for damages shall be limited to the foreseeable, typically occurring damage.

(9) The goods/articles marked with ''Export'' or ''forexport only'' may only be ordered/purchased for export outside Germany. These goods/spare parts may not be resold in Germany (area of application of the FRG) and may also not be installed or fitted in/on vehicles. These are design or utility/design patents or otherwise protected goods/articles which are not intended for use in the FRG.


The buyer of these items undertakes with the purchase to export these goods/items.

The Buyer shall indemnify ACR-Bielefeld Klangwerk GmbH against all obligations or claims of third parties, of whatever nature, arising from a breach of the obligations under sentences 1-4.

  • 10Warranty

(1) We shall be liable without limitation in accordance with the statutory provisions for damage to life, limb and health resulting from a negligent or intentional breach of duty by us, our legal representatives or our vicarious agents, as well as for damage covered by liability under the Product Liability Act. For damages which are not covered by sentence 1 and which are based on intentional or grossly negligent breaches of contract as well as fraudulent intent by us, our legal representatives or our vicarious agents, we shall be liable in accordance with the statutory provisions. In this case, however, the liability for damages shall be limited to the foreseeable, typically occurring damage, unless we, our legal representatives or our vicarious agents have acted intentionally. To the extent that we have given a guarantee as to the quality of the goods or parts thereof, we shall also be liable within the scope of this guarantee. However, we shall only be liable for damage based on the absence of the guaranteed quality but not directly occurring on the goods if the risk of such damage is obviously covered by the quality guarantee.

(2) We shall also be liable for damages caused by simple negligence, insofar as the negligence relates to the breach of such contractual obligations, compliance with which is of particular importance for the achievement of the purpose of the contract. However, we shall only be liable insofar as the damages are typically associated with the contract and are foreseeable.

(3) Any further liability shall be excluded regardless of the legal nature of the asserted claim; this shall apply in particular to tortious claims or claims for reimbursement of futile expenses instead of performance.

(4) Insofar as our liability is excluded or limited, this shall also apply to the personal liability of our employees, representatives and vicarious agents.

(5) ACR-Bielefeld Klangwerk GmbH shall not be responsible for material defects of the delivery which it obtains from third parties and passes on unchanged to the Buyer; the responsibility in case of intent or negligence shall remain unaffected in accordance with the above provisions.

  • 11Closing provisions

(1) Amendments or supplements to these Terms and Conditions must be made in writing. This shall also apply to the cancellation of this written form requirement.

(2) The law of the Federal Republic of Germany shall apply to the exclusion of the UN Convention on Contracts for the International Sale of Goods.

(3) The contractual language is German.

(4) The place of performance as well as the exclusive place of jurisdiction for all disputes arising from or in connection with this contract shall be our registered office, insofar as the buyer/client is a merchant.

(5) Should individual provisions of this contract be invalid or contradict the statutory provisions, this shall not affect the remainder of the contract. The ineffective provision shall be replaced by the contracting parties by mutual agreement by a legally effective provision which comes closest to the economic sense and purpose of the ineffective provision. The above provision shall apply mutatis mutandis in the event of loopholes.
